2 Product Overview
The SX Series Safety Laser Scanner is an electro-sensitive protective equipment (ESPE). It employs active opto-electronics
productive devices responsive to the diffuse reflection of a radiation (AOPDDRs), according to the definition and
requirements of international safety standard IEC 61496-3. The optical radiation is a class 1 infrared laser generated within
the device.
When the device is properly installed on a machine that presents a risk of personal injury, it provides protection by making
the machine revert to a safe condition before a person reaches the hazardous points.
The working principle is that the invisible beam of the laser creates a two-dimensional safety area that must be crossed to
reach the dangerous points. In this way the dangerous movement of the machine can be stopped before anyone reaches the
hazard point.
The safety area can be horizontal or vertical and by using a Graphic User Interface, its shape can be planned according to
the application needs.
The beam is emitted in short interval pulses and they are reflected by objects in the safety area. The device calculates the
distance to the object by measuring the time interval between the transmission of the pulse and its reception after being
reflected (time-of-flight principles).
The safety area is scanned by a mirror that deflects the light pulses over the 275° area around the device by rotating at a
constant speed. In this way, all the opaque objects that have a certain dimension can be detected in the safety area.
Within the sensing range of the scanner, two areas can be monitored simultaneously: one is the Safety Zone, that is used to
detect operators or objects entering a hazardous area; the other is the Warning Zone that can be defined with a longer
distance than the Safety Zone, allowing a configuration to detect objects that are approaching the Safety Zone.
Configurations can also be created with one Safety Zone and two different Warning Zones.
Basic (standard) and cascadable (master and remote) systems are available.
The scanner will only turn its Safety Outputs ON when the Safety Zone is free of obstructions, either automatically or
following a manual restart (reset) signal, depending on the operating mode.
When a scanner has the external device monitoring (EDM) function selected in the configuration, it does not require an
external controller. This function ensures the fault detection capability required by U.S. Control Reliability and ISO 13849-1
Category 3 and PL d for controlling final switching devices (FSDs) or Machine Primary Control Elements (MPCEs).
When a scanner does not have the EDM function selected (or is not an option), it should be connected to a self-checking
safety module, safety controller, or safety PLC/PES that conforms to the level of performance required by the risk
assessment. Examples include UM-FA-9A/-11A safety modules, SC10-2roe or XS/SC26-2 safety controller for applications
requiring Control Reliability and/or ISO 13849-1 Category 3 or PL d.

Make no modifications to the Scanner — The SX may not be modified, or the Protective function of the Scanner can no
longer be guaranteed. Where changes are made to the Scanner, all guarantee claims against the manufacturer of the
Scanner shall no longer apply.
Service life TM in accordance with DIN ISO 13849 — The SX’s PL and PFHd specifications refer to the TM service life of
20 years. Repairs or replacement of wear and tear parts do not extend the service life.
Protective function limits — The SX does not protect against (including, but not limited to):
• Parts that are ejected from a machine
• Splashing/spraying liquids
• Gases and vapors
• Radiation
Vapors, smoke, dust, particles — Vapors, smoke, dust and all particles visible in the air can cause the machine to switch
OFF unintentionally. Do not use the SX in environments in which heavy vapors, smoke, dust or other visible particles are
present.
Stray light limitations — Light sources (including infrared, fluorescent, and strobe lights) can impair reliability. Ensure that
no interfering light sources are present within the SX detection plane.
• Prevent reflective surfaces at beam level.
• Where applicable, take additional separation (safety) distances into account.
• Ensure that there are no other photoelectric sources within the SX detection plane that can impair performance.
Monitoring through a window restriction — Do not use the SX to monitor an area (scan) through any window or
transparent materials. Doing so can result in false detection that will cause nuisance machine stoppages.

• As a tripping device to initiate or reinitiate machine motion (PSDI applications), unless the machine and its control
system fully comply with the relevant standard or regulation (see OSHA 29CFR1910.217, ANSI/NFPA 79, ANSI
B11.19, ISO 12100, IEC 60204-1, IEC 61496-1, or other appropriate standard)
WARNING:
• Proper Use
• Failure to follow all instructions and warnings could lead to serious bodily injury or death.
• Only use the SX Series Safety Laser Scanner on machinery that can be stopped immediately after
a stop signal is issued at any point in the machine's stroke or cycle. Under no circumstances may
the Scanner be used on full-revolution clutched machinery or in unsuitable applications as those
listed.
• Allow only Qualified Persons to install and maintain the SX Series Safety Laser Scanner. Perform
the Shift/Daily checkout procedure at every power-up, shift change, and machine setup. Refer to
the instruction manuals and other reference materials (located in the Help menu) for all installation
details, wiring diagrams, operating instructions, shift/daily/periodic checkout procedures, and
warnings.
• If there is any doubt about whether or not your machinery is compatible with the SX Series Safety
Laser Scanner, contact Banner's Application Engineers.
2.3.2 Control Reliability: Redundancy and Self-Checking
Redundancy requires that the SX Series Safety Laser Scanner circuit components be backed up to the extent that, if the
failure of a single component will prevent effective machine stopping action when needed, that component must have a
redundant counterpart which will perform the same function. The SX Series Safety Laser Scanner is designed with redundant
microprocessors.
Maintain redundancy whenever the SX Series Safety Laser Scanner is in operation. Because a redundant system is no
longer redundant after a component has failed, the SX Series Safety Laser Scanner is designed to monitor itself
continuously. A component failure detected by or within the self-checking system sends a stop signal to the guarded machine
and puts the SX Series Safety Laser Scanner into a Lockout condition.
A recovery from this type of Lockout condition requires:
• Replacing the failed device (to restore redundancy, only performed by Banner Engineering Corp.)
• Performing the appropriate reset procedure
Use the Diagnostic Display to diagnose causes of a lockout condition. See Troubleshooting on p. 104.
2.3.3 Application Checklist
The SX Series Safety Laser Scanner can provide a protective function only when its settings and connections (software
configuration, Safety and Warning Zone dimensions, electrical interfacing, mounting, environmental conditions, supplemental
safeguarding, etc.) are coordinated with its application. The checklist items below and the following application examples are
intended to give additional guidance in applying the SX Series Safety Laser Scanner.
The following items are provided to assist in creating a checklist or to be included in a risk assessment for the application of
the SX. Additional items may be required, depending on the application.
• Review this instruction manual
• Identify the appropriate application (required resolution, field orientation, etc):
◦ Expert for horizontal applications
◦ Vertical for vertical applications
• Determine the area to be safeguarded and the SX's installation location and means.
• Determine whether the SX requires protection from mechanical damage.
• Ensure that the environmental conditions do not exceed the SX specifications.
• Determine the size and coverage of the Safety Zone and Warning Zone (if used) depending on:
◦ Physical location of the SX installation,
◦ The minimum safety distance or the stopping distance of the mobile vehicle
◦ The height (H) of the Protective Field (horizontal applications)
◦ Other factors that may require an increased minimum safety distance (e.g. "shadowing", adjacent SX, retro-
reflective surfaces, brake performance degradation)
•
Important: It is recommended to visibly mark the Protective/Warning Field boundaries, if possible.
• Assess the possibility of avoiding detection by the SX by climbing/stepping over, crawling under, moving around the
protection field(s), either at the perimeter of the fields or in unprotected areas caused by the shadow effect.
• Determine whether additional/supplement safeguarding is required.
• Determine the proper startup, start/restart (manual/automatic reset), and other safety-relevant parameters. If the
manual restart is used, determine the position for the reset button.

• Determine whether Zone Set switchover is required and identify the conditions for its use.
• Determine whether the Reference Point function is required (at least three (3) reference points must be defined on
fixed surface(s)).
• Determine the method and means of electrical interfacing dependent on the level of risk determined by the risk
assessment (e.g., OSHA/ANSI control reliability or ISO 13849-1 category 3 PLd).
2.3.4 Sample Applications
The SX Series Safety Laser Scanner is used to detect people who are approaching a hazardous area, before reaching it, to
prevent hazardous circumstance (i.e. mechanical movement) that may cause an accident.
The protective detection is done by defining a safety area (the red zone in the figures), whose shape and dimensions must
be designed according to the risk assessment of the machine. The user must consider the position of the hazardous points,
the shape of the machine and of the environment that surrounds it, and the time needed to stop the dangerous movement.
To better ensure people's safety, it is possible to define a warning area (the green zone in the figures): if a person or an
object is approaching too close to the safety area, the safety laser scanner can trigger warning devices. This warning area
cannot be used for safety purposes.
The following application examples should be considered just as references for instructional purposes.
Stationary Area Guarding (Horizontal Danger Zone Guarding)
Area Guarding uses a horizontal sensing field (i.e., Safety or Warning Zones) to continually sense an individual within a
safeguarded area. Area Guarding can reduce or eliminate the possibility of a pass-through hazard that could result in an
individual being exposed to unexpected machine startup or motion.
As an individual approaches, the Warning Zone (the green area) can illuminate a warning beacon or sound an alarm that the
Safety Zone (the red area) is about to be entered. In conjunction with markings on the floor, the use of a Warning Zone can
eliminate intermittent stopping due to individuals being unaware of the safeguarded area. When the Safety Zone is
encroached upon, a stop is issued and the hazard is brought to a safe state.
Figure 4. Horizontal stationary area guarding
Typical considerations for horizontal stationary area guarding:
• In this example, the SX is mounted in the center of the operator work station to maximize the available size of the
Safety and Warning Zones. The SX is mounted directly to the cell's perimeter guarding fencing 300 mm above the
floor to prevent crawling under the Safety Zone.
• In this example, physical damage is not expected because the fencing provides adequate protection. If interference
with the operator is expected, the Scanner can be recessed into the fencing to minimize exposure.
• The typical manufacturing setting is well within the SX's environmental ratings.
• The size and coverage of the Safety Zone must ensure that the hazard cannot be accessed by moving (reaching)
around, under, or over the Safety Zone. Access to the hazard is prevented by the fencing along the side of the Safety
Zone, which minimizes the required floor space.
• For this example, assume a robot stopping time of 100 ms, SX response time of 62 ms, the response time of a safety
interfacing device is 25 ms (UM-FA-9A safety module). Because an individual can reach over the detection plane by
bending at the waist, the Dpf adder is equal to 1200 mm (U.S. formula) and the Measurement Tolerance Factor
(ZSM ) must be accounted for. This gives a safety distance of:Ds = 1600 mm/s × (0.1s + 0.062s + 0.025s) + 1200
SX Safety Laser Scanner
12 www.bannerengineering.com - Tel: + 1 888 373 6767
mm + 150 mm = 1649 mm (64.9 in). In other words, the leading (outside) edge of the Safety Zone must be 1649 mm
from the nearest hazard.
• It is recommended to mark the boundary of the Safety/Warning Zone on the floor.
• This example has no factors that would require an increase in the safety distance.
• There is no possibility of easily stepping, climbing or otherwise avoiding detection.
• Because there is no pass-through hazard, the SX can be configured for "automatic start/restart (reset)". However, the
machine control circuitry must be designed so that one or more initiation devices must be engaged (e.g. a conscious
act is required) to start the machine.
• Further, any initiation devices (or reset switches) must comply with the Reset Switch Location.
• For the purpose of this example, the UM-FA-9A Universal Input Safety Module was used and interfaced in a control
reliable (category 3 or 4) method as described in the wiring diagram.
Stationary Area Guarding with Zone Set Switchover
An Area Guarding application can use the Zone Set Switchover function to automatically allow access to one area while
simultaneously guarding another hazardous area. This can improve machine cycle efficiency by allowing the operator to
remove/place parts while the operation is in a different area, for example.
The robot position (i.e., the location of the hazard) is monitored to identify when no hazard exists at one work station, at
which time the Zone Sets are switched. The Zone Set Switchover function is much like a muting application for a safety light
screen.
Figure 5. Sample application with Zone Set Switchover
In addition to the typical considerations for horizontal stationary area guarding, for this example:
• Ensure that no individual is exposed to a hazard while employing the Zone Set switching function. The risk
assessment should determine the applicability of this function, means of selecting Zone Sets in respect to failure
modes, and whether supplemental safeguarding is required.
• In higher risk applications that require control reliability (category 3 or 4) interfacing, it is highly recommended to use
redundant sensors or switches to initiate or enable a Zone Set change.
• If two Zone Sets are used the Warning Auxiliary output can be used in conjunction with the Warning Zones. If three
Safety Zones are desired (right, left, entire area) then the Warning output pin is required for selecting the Zone Set
(Safety Zone).
Stationary Area Guarding with Multiple Scanners
Area Guarding is frequently used in conjunction with other safeguards, such as interlocked gates on fencing or vertically
positioned safety light screens/grids (for example, perimeter guarding). The purpose of the safeguarding located at the
perimeter of the work cell is primarily to detect entry into the hazardous area, while the area guarding (for example, the SX) is
responsible for preventing machine restart or other machine hazards while the individual remains within the work cell.
In such applications, it is important not to have any voids or unmonitored areas (dead spaces) in the detection capability of
the Area Guarding system. The SX can be configured for irregularly shaped protection fields to accomplish this.
Important: Area Guarding and Perimeter Guarding should not be used in place of Lockout/Tagout
procedures.

In addition to the typical considerations for horizontal stationary area guarding listed in example #1:
• Install multiple SX with a vertical offset height of 100 mm (or more) or use physical shielding to prevent one SX from
interfering with another SX.
• Be aware of the effect of needle- and cone-shaped fields and eliminate areas of unreliable detection.
• Eliminate the "shadow effect" and/or use additional safeguarding.
• Configure the SX for start/restart interlock (manual reset) to ensure that the Scanner does not turn ON its safety
outputs if an individual is momentarily undetected (e.g., climbs up onto the machinery above the plane of the
Protective Field).
• Configure any perimeter guarding systems (e.g., an interlocked gate or safety light screen) for a manual reset; any
reset switches must comply with the Reset Switch Location Section.
Mobile Area Guarding on Transfer Carts/Trolleys and Automated Guided
Vehicles (AGVs)
On mobile applications, such as transfer carts, the SX monitors the area directly ahead of the cart using both the Warning
and the Safety Zones. If something is detected within the Warning Zone (the green area), the alarm output signals the vehicle
logic to slow the vehicle and sound a horn (or other awareness device). The SX stops the vehicle when something is
detected within the Safety Zone (the red area). If the speed increases or decreases, alternate Zone Sets can be used to
adjust for varying stopping distances.
Figure 7. Mobile area guarding on AGVs
Typical considerations for mobile vehicle guarding (horizontal fields):
SX Safety Laser Scanner
14 www.bannerengineering.com - Tel: + 1 888 373 6767
• In this example, the mobile vehicle is a transfer cart that travels in two directions along a pair of rails. Each direction
of travel is guarded by separate, individually configured Scanners on either end of the vehicle, mounted 150 mm (5.9
inch) above the plane of the floor (not the rails). The plane of the Safety Zone should not exceed 200 mm (7.9 in)
above the floor.
• In this example, physical damage is not expected because the path of travel is restricted.
• The typical manufacturing setting is well within the SX's environmental ratings.
• Safety Zone Length (Minimum Distance D): For this example, assume a maximum vehicle speed of 1200 mm/s (48
in/s), a breaking distance of 900 mm (35 in), SX response time of 122 ms (4 scans), the response time of a vehicle
drive and safety interfacing 100 ms, which results in an overall stopping distance of 1166 mm (46 in). DSD = [1200
mm/s × (0.1s + 0.122s)] + 900 mm. This value is added to the Additional Distance Factors (Z) to determine the Safety
Zone length , which for this example are:
◦ ZSM = 150 mm (5.9 in)
◦ Zrefl = 0 — The possibility of retro-reflectors located within the scanning plane of the Protective Field can be
excluded.
◦ ZF = 100 mm (4 in) — To the ground clearance of the transfer cart's sides is 60 mm (2.4") and the wheels are
not accessible.
◦ ZA = 500 mm (20 in) — The possibility of crushing/trapping hazard against the overhanging conveyor and the
transfer cart is an application specific addition for this example.
◦ The total Safety Zone length (Minimum Distance) from the SX to the leading edge of the Safety Zone is 1916
mm (75.4 in).
• Safety Zone Width (Additional Side Distance Z): The Z factors to determine the Safety Zone width are primarily the
same as above (ZSM = 150 mm, Zrefl = 0, ZF = 100 mm), but the application specific adder, ZA(SIDE), is now used to
account for the entire area to the sides the cart and under the overhang of the conveyor. This distance is 300 mm (12
in); ZSM + ZF = 250 mm (9.8 in) , thus ZA must equal 50 mm (2 in) to ensure the entire area to the sides of the cart are
monitored. The total width of the Safety Zone for this example is 1666 mm (66 in), which is the width of cart of 1066
mm (42 in) plus the value of the two 300 mm side distances.
• A 190° Safety/Warning Zone should be used to minimize any unmonitored area at the SX's sides.
• The vehicle's maximum speed should be identified in the SX's configuration. In this example the maximum speed is
1200 mm/s.
• The Warning Zone is used to slow the transfer cart and sound a horn if an object is detected.
• The design of the transfer cart ensures that there are no protruding loads (e.g., pallets) that could become a hazard.
• The fencing (supplemental safeguarding) along the path of the transfer cart reduces the risk of an individual stepping
directly in front of the cart; this allows the Safety Zone width to be minimized. The fencing also reduces, but does not
eliminate, the possibility of crushing/trapping hazards between the transfer cart and the conveyor because the
individual is detected by the leading edge of the Safety Zone.
• In this example, the movement of the transfer cart is controlled primarily by on-board logic that is safety-rated. This
allows the movement to begin after the material control system (conveyor logic) commands the cart to a specific
location. Automatic restart function must incorporate a two-second delay after the Safety Zone becomes clear (per
ISO 3691-4).
The on-board logic of the transfer cart that controls beginning and stopping motion and the means of electrical interfacing
must be evaluated during the risk assessment to meet the required level of safety performance (e.g., control reliability or
category 3 or 4).
Vertical Guarding with Reference Point Monitoring
This example application uses two SXs with Safety Zone Switchover to safeguard a pallet load/unload station. The two
Safety Zones per SX are enabled (the red lines) and disabled (pink shaded areas) as pallets are loaded/unloaded and as
they enter/exit the work cell at the rear of the station.
The SX's Area Switch inputs identify the position of a pallet to determine which Safety Zone to disable. The Reference Points
(blue points) ensure that the Safety Zones are in the proper position.
SX Safety Laser Scanner

Figure 8. Vertical guarding with reference contour monitoring
Typical considerations for vertical guarding:
• In the example shown, the objective is to prevent an individual from entering an area; detecting the body (torso) is
required.
• In this example, physical damage is not expected because the SX is mounted above and away from the probable
path of the forklift. If impact is possible, a mechanical guard/shroud can be added to protect the SX without blocking
the Safety Zones.
• The typical manufacturing setting is well within the SX's environmental ratings.
• The size and coverage of the Safety Zone must ensure that unrestricted or accidental entry to the work cell is
prevented. Two SXs are used to create four Safety Zones to cover each end of the pallet load/unload station (e.g. left
side SZ, right side SZ, and both sides SZ). When no pallets are at the station, the front SX has a Safety Zone that
covers both sides; the rear SX can be muted to allow pallets to be fed into the station (such as pallets exiting the cell).
As pallets are loaded, sensors monitoring the pallet position switch the Zone Sets to "turn off" the front Scanner's
right side and "turn on" (and unmute) the rear SX's Safety Zone for that side (as shown). This allows the forklift to pick
up the pallet and remove it.
• When the front Safety Zone is inactive, the pallet must completely block the opening to prevent access. When the
pallet is removed, that Safety Zone must immediately be re-activated.
• The use of the Reference Points is required for vertical guarding applications (e.g. the blue points).
• In this example, no factors would require an increase in the safety distance.
• For this example, assume a machine stopping time of 200 ms, SX response time of 62 ms; safety interfacing device
(UM-FA-9A safety module) response time is 25 ms. The resolution can be either 40 or 70 mm, since only body
detection 70mm can be selected, the Dpf adder is equal to 900 mm (U.S. formula). This gives a safety distance of:
Ds = 1600 mm/s x (0.2s + 0.062s + 0.025s) + 900 mm = 1359 mm (53.5 in). In other words, the plane of the rear
Protective Field must be no closer than 1359 mm (53.5 in) from the nearest hazard (assuming no hazard inside the
load station).
• Configure the SX for start/restart interlock (manual reset) to ensure that if an individual interrupts an active Safety
Zone while attempting to enter the guarded area that the SX's OSSD safety outputs remain OFF until manually reset
after the individual exits the cell.
• For the purpose of this example, the UM-FA-9A Universal Input Safety Module was used and interfaced in a control
reliable (category 3 or 4) method as described by Section 3 and Figure 3-19.
Mobile Area Guarding with Side Vertical Guarding
Vertically guarding the sides of transfer carts, material-handling trolleys, and Automated Guided Vehicles (AGVs) prevents
contact with objects that may have overrun the stop position of a conveyor, which could result in damage to the mobile
vehicle and the conveyor. This type of guarding can also be used for situations that with a crushing/trapping hazard, for
example, a distance less than 500 mm (20 in) between the sides of the SX and a physical structure.
Two SXs are positioned to create horizontal Safety Zones, to prevent running over objects or individuals in the path of the
vehicle. A second pair of vertically mounted SXs is positioned to detect objects at or above the horizontal plane of the SXs
that are looking ahead of, and behind the vehicle. In this configuration, the "leading edge" of the Safety Zone is now provided
by the vertical edges on the sides of the SX. These edges will detect the torso of an individual; 70 mm resolution is typically
selected.
SX Safety Laser Scanner
16 www.bannerengineering.com - Tel: + 1 888 373 6767
Figure 9. Mobile area guarding with side vertical guarding
In addition to the typical considerations for mobile area guarding (see Mobile Area Guarding on Transfer Carts/Trolleys and
Automated Guided Vehicles (AGVs) on p. 14):
• Select 70 mm resolution for torso detection.
• Set the leading edge of the vertical Safety Zone no shorter (smaller) than the corresponding horizontal Safety Zone
(assuming that the response times and safety distances are equal).
• Position the vertical Safety Zones at a slight angle so that the lower Safety Zone edges protrude over the vehicle
width by the amount of the additional distances ZSM , ZF , ZREFL and ZA when required (see Vertical Guarding with
Reference Point Monitoring on p. 15).
• The configuration of reference points, as with other vertical guarding applications, is not required, because the
approach of the individual is detected by the edge of the Safety Zone and not the plane. As with the horizontal Safety
Zones, the vertical Safety Zone must be checked (verified) on a periodic basis.
• Minimize crushing/trapping hazards by using supplemental safeguarding, such as by preventing access (e.g.,
fencing) or by causing the individual to be detected by the leading edge of the horizontal Safety Zone.
2.3.5 Applications with Master and Remote Scanners
In applications where you need to monitor several zones that are not visible from just one point, use more than one scanner.
However, there may be just one safety function, for example dangerous movement that must be stopped when something is
detected inside the area.
The SX Laser Scanner can effectively solve this situation. Up to four scanners can be easily connected to each other through
an Ethernet-based safe communications bus, working as a single system (cascading the scanners).
Only the Master Unit receives power, has inputs and outputs onboard, and must be connected to a PC to configure the entire
system.
The Remote Units (cascaded units) are connected to the Master with a single cable that also provides them with power. The
synchronization of up to four (4) scanners is an integrated function. There is no need for extra external control units.
2.4 Operating Features
The Banner SX Series Safety Laser Scanner models described in this instruction manual feature several functions.
Configuring some of these functions must be accomplished by a Qualified Person to ensure that personnel who are exposed
to potentially dangerous situations are adequately protected. Features include:
• Selecting automatic or manual start/restart
• Configuring the response time
• Setting the Warning and Safety Zones
• Defining a Warning output
• Configuring a muting evolution
• Cascading up to four scanners in one chain
• Interfacing encoder inputs in AGV applications for assistance in selecting Zone Sets
For more information, see Configuration Instructions on p. 67.

2.5 Memory Device for the Master Models
The memory device is a removable memory box included on all master scanner models (not on remote or stand-alone
models). The memory device stores the scanner configuration for an individual scanner or a chain of scanners.
The memory device saves the configuration when the PC transfers the operational parameters to the scanner. This simplifies
the replacement of a faulting or damaged scanner. When the original scanner is replaced and the memory device is
connected to a new scanner, it is very easy to install the configuration on that new scanner (no PC required).
To replace your scanner and/or memory devices, refer to Fast Replacement of the Master Scanner on p. 125.
The memory device is also the point of cable connections for a master unit. For the cable connection process, refer to
Mounting and Unmounting the Removable Memory on p. 45.
2.6 Reference Points (Surface) Monitoring
The reference points (surface) monitoring function prevents unintentional misalignment and deliberate manipulation of the
SX.
If the configuration contains reference points, the SX monitors both the Safety Zone (for intrusions) and the reference points
(for position). If the distance between the scanner and the reference surface (point) changes from the configuration (greater
than the assigned tolerance), the SX detects the change and switches the OSSDs to OFF.
The design of the installation and the risk assessment must identify the need and use of the reference points (surface)
monitoring function. In horizontal applications, this function ensures that the safeguarded area does not change due to the
SX moving or changing position because of an impact, vibration, or poor maintenance practices. In a vertical application, the
position of the Safety Zone has a critical effect on the separation (safety) distance. If there is an angular movement of the SX
that causes the Safety Zone to be positioned closer to the hazard, an individual could access the hazard before the machine
can stop.
With a vertical Safety Zone (angle of approach greater than ±30°), it is required that at least three (3) reference points be
assigned. The reference points must be assigned on a surface that will be present but do not have to be at the edge of the
Safety Zone. The surface must be within the safety range for the configured resolution of the scanner. The reference points
should be on at least two sides, areas, or surfaces.
For more information on how to create a Safety Zone and use reference points, see Safety Zone Area - Length and Width on
p. 39.
Note:
•Reference Points
• Failure to follow these recommendations can potentially create a dangerous situation that may lead
to serious injury or death.
• The design of the installation and the risk assessment must identify the need and use of the
reference points (surface) monitoring function. A change in the position or mounting of the SX can
result in gaps/unmonitored areas and an incorrect (too small) safety distance (minimum distance).
If is recommended that Reference Point Monitoring be used for all stationary applications that have
surfaces that can be monitored.
2.7 Passwords
Improperly set parameters on the SX can cause serious accidents. The configuration of the SX is therefore protected by
passwords.
Banner SX Scanner software is not password protected. Users can create and save (to the PC) a configuration file without
entering a password. A password is required to upload a configuration to a SX.
Ensure that the passwords are secured by the Qualified Person. The default password is admin. Call Banner Engineering
technical support if a password is unknown.
The people responsible for the machine's safety must ensure that the appropriately Qualified Person can properly perform
the tests and work on the machine and the SX in accordance with their intended use.
2.8 Laser Safety (Class 1)
The SX Series Safety Laser Scanner has a Class 1 laser.

Figure 11. Class 1 laser characteristics
2.8.2 For Safe Laser Use (Class 1 or Class 2):
• Do not stare at the laser.
• Do not point the laser at a person’s eye.
• Mount open laser beam paths either above or below eye level, where practical.
• Terminate the beam emitted by the laser product at the end of its useful path.
CAUTION:
•Never stare directly into the sensor lens.
• Laser light can damage your eyes.
• Avoid placing any mirror-like object in the beam. Never use a mirror as a retroreflective target.
2.9 Software Overview
Use the configuration software to establish operational settings for the SX and to display measurement and system
information produced by the SX. Communication between the PC and the SX is via an Ethernet network.
The scanner ships from the factory unconfigured. The unit must be configured for each application.
The configuration settings are created by a trained and Qualified Person who understands the SX instruction materials.
These settings are saved in an .xml configuration file and includes all the information that the SX requires for its intended
operation. An SX's configuration file includes the following data:
• Administrative data, for example file name, application description
• Safety-relevant data, such as the startup process
• Safety Zone or Warning Zone configuration data, for example contours and limits
The menu progression in the program assists the user with the configuration process.

2.9.1 System Requirements
To use the system, the personal computer must meet the following minimum requirements:
Component Recommended Minimum
Processor(s) Pentium 4 Pentium 4
Clock frequency ≥ 3 GHz ≥ 2 GHz
RAM 2 GB 1 GB
Free hard drive space 70 MB 70 MB
Monitor resolution 1280 × 768 1024 × 768
Supported operating systems Windows 7, Windows 8, Windows 10
The PC must also be equipped with the following hardware and software drivers:
• Installed Ethernet network card and installed driver
• One free 100 Mbps Ethernet port
2.9.2 Safety and Warning Zones
The software makes it easy to establish Safety and Warning Zones. The Safety Zone and the Warning Zone are user-defined
areas that the scanner monitors.
An intrusion into the Safety Zone (such as a person walking into a monitored work cell) causes the SX to turn its safety
outputs off. An intrusion into the Warning Zone causes the SX to create a warning signal.
Safety Zone and Warning Zone settings are created and saved as zone sets. The number of configurable zone sets available
for the SX are dependent on the model.
Model Type of Unit Cable Wiring Maximum Zone Sets
SX5-B and SX5-B6 Stand-alone 8-pin 6
SX5-M10 Master 8-pin 3
SX5-M10 Master 12-pin 10
SX5-M70 and SX5-ME70 Master 17-pin 20
SX5-M70 and SX5-ME70 Master 17-pin and 8-pin 70
Zone sets can be enabled or disabled, one set at a time, while the SX is operational and actively monitoring a work area.
This function is useful when changing machine guarding requirements create the need for changes in Safety Zone and
Warning Zone dimensions.
2.9.3 Monitored Space Display
When the SX is actively monitoring an area, it measures the distance to, and the angular position of, objects in the area.
These measurement data are transferred via an Ethernet connection to the PC when the Monitoring function is selected. The
software uses this data to constantly update the display to show the Safety Zone and Warning Zone along with the measured
surfaces of the monitored area.

• The requirements for electrical safety and electromagnetic compatibility and the regulations or standards in all
countries and/or regions, must be met by the power supply where the laser scanner is used. If the device power
supply is shared with the machine or other electronic devices, voltage fluctuations to the laser scanner or noise
influences to the scanner may occur due to temporary changes of the current consumption on the machine or the
other electronic devices. We do not recommend sharing the laser scanner power supply with the one for the machine
or the other electronic devices, because the device may go to an error state in such circumstances.
• Do not run the connection cables in contact with or near high-voltage cables and/or cables which undergo large
current variations (i.e. motor power supplies, inverters, etc.).
• Access to the configuration tools must be restricted to only highly qualified personnel. The configuration upload
process through the GUI is allowed only by password.

3 Install Your Scanner
A horizontal Safety Zone is considered to be 30° or less from a level floor or walking surface.
1. Determine the area to be safeguarded by the scanner.
2. Determine whether to install the SX with or without a Banner mounting option.
3. Determine the size and coverage of the Safety Zone and Warning Zone (if used) depending on: physical location of
the scanner installation, and the minimum safety distance or the stopping distance of the mobile vehicle.
See Minimum Safety (Separation) Distance for Stationary Applications on p. 34 and Mobile Applications on p. 38.
4. Determine the restart operating mode (manual or automatic reset). See Automatic or Manual Start/Restart on p. 67.
5. If Manual restart is used, determine the location for the reset switch, see the reset switch location section of the
manual.
6. Determine if a Zone Set switchover is required and identify the conditions for use.
7. Configure the SX with the configuration software.
8. Record the SX configuration and the Safety/Warning Zone dimensioning. This document should identify and be
signed by the individual(s) responsible for the configuration and be included with the machine documentation.
9. For stationary applications, it is recommended to mark the perimeter of the Safety Zone(s) on the floor as an
awareness means for individuals in the area. For mobile applications, it is recommended that the diagram be readily
available for review.
10. If required, install means to protect the SX from physical damage, sources of optical interference (e.g. other
scanners), or prevent the SX from being used as a climbing aid. Ensure that these means do not impair the SX's field
of view.
3.1 Safety Zone (SZ) and Warning Zone (WZ) Considerations
• Ensure the dimension (size) and coverage of the Safety Zone can detect an intrusion and allow the scanner's OSSDs
to stop the dangerous movement before personnel can access the hazard. (See Minimum Safety (Separation)
Distance for Stationary Applications on p. 34 and Minimum Distance D (Safety Zone Length) for Mobile Applications
on p. 40.)
• Ensure that access to all hazards is not possible for all Zone Set switchover applications.
• Ensure that safety distance and stopping distance calculations incorporate all factors that can effect response time,
including:
◦ The additive effect of all device response times, such as the scanner, UM-FA-… safety module, and all
machine control elements (FSDs and/or MPCEs).
◦ Add the appropriate response time values to account for any reasonably foreseeable machine stop time
degradation, such as due to brake pad wear.
• Ensure that the Safety Zone adequately covers all access routes that may lead to the safeguarded hazard or
supplemental guarding may be required (see Unmonitored Areas on p. 27).
• Ensure that the safeguarded hazard(s) cannot be accessed because of the effect of "shadowing" within the Safety
Zone by adding supplemental safeguarding, such as additional scanners.
• Observe the lateral tolerance when dimensioning the Safety Zone (e.g. do not use needle or cone-shaped boundaries
to define the separation (safety) distance; cone-shaped boundaries rely on less accurate, angular resolution
measurements).
• Consider and resolve any other application factors that might require an increase in the separation (safety) distance
or stopping distance. These factors should be identified via the risk assessment process.
• Determine if the reference points (surface) monitoring function is required (especially in vertical applications). This
function prevents unintentional misalignment and deliberate manipulation of the SX (see Reference Points (Surface)
Monitoring on p. 18).
3.2 Mechanical Installation Considerations
Many factors influence the layout of the SX’s mechanical installation. For stationary applications, these include separation
(safety) distance, supplemental safeguarding (hard guarding), unmonitored areas (shadows or areas behind the SX),
adjacent SXs, and the height of the Safety Zone (in horizontal applications). In addition, mobile applications must take into
account the stopping performance and distance of the mobile vehicle the SX is controlling.
SX Safety Laser Scanner
26 www.bannerengineering.com - Tel: + 1 888 373 6767
WARNING: The Hazard Must Be Accessible Only through the Sensing Field
The installation of the SX must prevent any individual from reaching around, under, over or through the
sensing field and into the hazard without being detected. Mechanical barriers (for example, hard (fixed)
guarding) or supplemental safeguarding may be required to comply with this requirement, and is
described by ANSI B11.19 safety requirements or other appropriate standards. Failure to follow these
instructions could result in serious injury or death.
3.2.1 Unmonitored Areas
WARNING:
• Unmonitored areas can create an access route to the hazard or a blind zone where a person
cannot be detected. The area behind the Scanner and near it, on either side is not monitored.
• Failure to minimize the unmonitored area could result in serious bodily injury or death.
• Minimize the unmonitored area so that no one can access this area undetected (for example, by
recessing the Scanner into the machine, using supplemental safeguarding, or using mechanical
barriers to prevent access).
Behind and To the Sides of the Scanner
The area behind and on either side the SX is not monitored. It must not be possible to walk in unmonitored areas or
otherwise access them. This can be accomplished by recessing the SX into the machine, using supplemental safeguarding,
or using mechanical barriers to prevent access. If there is a possibility that the SX could be used as a climbing aid or
standing surface, use a physical cover set at an angle over the SX.
Special attention to these areas must be addressed in vertical Safety Zone applications so that the resolution at the edges of
the Safety Zone does not increase. If an increased resolution cannot be prevented, then the worst-case resolution must be
used to determine the Dpf (U.S. formula) or the C factor (European formula) in the safety distance calculations.

Shadowing Within the Safety Zone
WARNING:
• Permanent and moveable objects in the Safety Zone can create a shadow that results in an
unprotected zone that may provide an access route to the hazard.
• Failure to eliminate access routes caused by the shadowing effect could create a potentially
dangerous condition that may lead to serious injury or death.
• Eliminate any unprotected access routes by repositioning the SX, installing additional SXs, or by
adding supplemental safeguarding.
Objects that are located within the Safety Zone create an unmonitored area directly behind the object. This area is best
described as a shadow, since the light emitted by the SX cannot bend around or penetrate through solid objects. The shadow
effect can be caused by both opaque and transparent objects.
Any unmonitored areas resulting from the shadow effect must not allow unprotected access routes to the hazard. This can be
prevented by repositioning the SX, installing additional SXs, or by adding supplemental safeguarding.
If the object is moveable, such as a scrap bin, do one or more of the following:
• Locate the unmonitored area at a greater distance from the hazard than the calculated safety distance;
• Enable an alternate Zone Set when the object is relocated; or
• The moveable object must be interlocked to stop and prevent the safeguarded hazard, if the object is moved.
• Identify the object with Reference Points (see Reference Points (Surface) Monitoring on p. 18)

Needle- and Cone-Shaped Safety Zone Contours
WARNING:
• Needle- and Cone-shaped Safety Zone contours
• Boundaries or contours that rely on too few measurement points (e.g., one or two) may not reliably
turn OFF the OSSDs when an object is present.
• Any safety distance calculations must consider and resolve the effects of needle- or cone-shaped
Safety Zones.
Needle- and cone-shaped Safety Zone boundaries are not recommended, because they may not reliably detect and respond
to objects (for example, turn OFF the OSSDs), compared with smooth-field boundaries made up of multiple measurement
points. Two effects are to be considered:
1. Not identifying the proper size of the detected object (outward cone shapes), and
2. An increase in resolution (inward cone shapes).
SX Safety Laser Scanner
28 www.bannerengineering.com - Tel: + 1 888 373 6767
Outward Needle- and Cone-Shaped Field Contours — An object equal to or greater than the stated resolution (e.g., 70
mm) will be detected at point A (Object 1), because enough sensing points are present at that location to detect the full 70
mm size of the object.
Objects 2 or 3 may not be identified as being larger than the resolution because at that distance, the angle is too narrow (and
has too few sensing points) to detect the full 70 mm resolution size.
Inward Needle- and Cone-Shaped Field Contours — The effect of an inward cone-shape is to increase the effective
resolution immediately adjacent to the shape. For the Scanner to identify that an object is equal to or greater than the stated
resolution (e.g., 70 mm), the entire object must be within the Safety Zone to turn OFF the OSSDs (e.g., Object 4). When an
object enters the unmonitored cone-shaped area, the start/restart inhibit function will enable a reset as soon as the object
portion within the Safety Zone is smaller than the stated resolution (Objects 5 and 6). This will turn ON the OSSDs if the
configuration is set to automatic restart, or if the reset switch is actuated.
To prevent a safety distance that is too short at that point, the increased effective resolution must be used to determine the
Dpf or C factor in the respective safety distance formulas. If a cone-shaped field must be used and the safety distance cannot
be complied with, additional supplemental safeguarding must be used.
To verify Safety Zone effectiveness, perform a trip test.

3.2.2 Adjacent SXs
WARNING:
• Interference from Adjacent SXs
• Interference from adjacent SXs may cause the OSSDs to go to the OFF state.
• SXs with a clear line of sight to another SX and that share the same detection plane with it, must
be adjusted or shielded so that their light pulses are not detected by the adjacent SXs.
The SX design minimizes the possibility of optical interference from adjacent Scanners. Light from adjacent scanners
(including those of other manufacturers) can cause OSSDs to go to the OFF state. To eliminate the possibility of optical
interference causing the OSSDs to turn off:
• Install mechanical shielding/barriers in stationary applications (both horizontal and vertical Safety Zones).
• For scanners mounted side-by-side, this shielding must be at least at the height of the front screen (window) and
flush with the front of the housing.
◦ Ensure that the means of shielding does not create any unmonitored areas.
◦ Install SXs at an off-set height greater than the height of the scanner output window (60 mm).
• Install SXs with Safety Zones with a crossed alignment.

To further aid in cross talk avoidance, the scanners feature four selectable scan codes. See Anti-interference Coding on p.

3.2.3 Light Interference
Reflective surfaces located near the safety device may cause passive reflections. These reflections can affect the detection
of an object inside the safety zone. The passive light sources can be an incandescent lamp, sunlight, a fluorescent light, a
strobe light or other infrared light sources.
Do not install the SX Series Safety Laser Scanner near strong and/or flashing light sources.
Ambient light may interfere with the functioning safety laser scanner. If the installation requires direct exposure to ambient
light, the scanner must be positioned so that the light does not enter the output window within ±5° of the detection plane.
Figure 23. Position the scanner to avoid light interference
±5°
CAUTION: In all applications where strong light within ±5° of the detection plane cannot be avoided, apply
an additional distance (Zamb) to the Minimum Safety Distance calculations. This distance could be
influenced by the selected Dust Filter Level and the presence of reflective backgrounds of light sources
(e.g. halogen lamp with back reflector). For all models except SX5-B, an additional distance of 200 mm is
typically enough to prevent any reduction in the detection capability (for the SX5-B see Additional
Information on p. 130 to determine the extra distance needed). See the minimum safety distance
calculation section ( Minimum Safety (Separation) Distance Formula on p. 35), and the dust filtering
section ( Dust Filtering on p. 32).
CAUTION: In any case where bright light is present outside the ±5° range, the additional distance is still
highly recommended.
Important: In cases of both light interference and high reflective backgrounds, additional distances do not
have to be summed, but the longest distance should be used.
3.2.4 Highly Reflective Backgrounds
If there is a highly reflective background within 3 meters of the safety zone boundary, for example a metallic glossy surface,
the SX Series Safety Laser Scanner might fail to recognize the exact distance of the detected object.
In this situation, we recommend reducing or removing the reflecting background.

Additional distance for

High-Reflecting Background
CAUTION: In all applications where highly reflective backgrounds within 3 meters of the Safety Zone
boundary cannot be avoided, an additional distance (Zamb) must be applied to the Minimum Safety
Distance calculations. This distance also depends on the Dust Filter Level setting and on the background
characteristics. For all models except SX5-B, an additional distance of 200 mm is typically enough to
prevent any reduction in the detection capability (for the SX5-B, refer to Additional Information on p. 130
to determine the extra distance needed). See the minimum safety distance calculation section ( Minimum
Safety (Separation) Distance Formula on p. 35), and the dust filtering section ( Dust Filtering on p. 32).
3.2.5 Anti-Tamper Function
The scanner continually monitors for conditions caused by tampering in the work area and/or the device that may create
interference or improper operation leading to a potential loss or reduction in the safety function. If these conditions are found,
the device forces a STOP condition and the display shows the full stopped state until the condition ceases.
Figure 25. Full stop state
The forced STOP state is activated within 30 ms when the device does not receive a return signal powerful enough to be
processed (seen) on at least 700 consecutive beams of scanner path (equal to or greater than an angular section of 70°).
The forced STOP state ends within 30 ms of the mentioned condition ceasing for at least 50 consecutive beams (equal to or
greater than an angular section of 5°) of the 70°.
This anti-tamper condition can occur in various situations in the field. The most common conditions are:
• No objects are present up to the maximum working distance of 50 m over a portion of the scanner area.
• Objects are present at a distance less than 50 m on a portion of the scanning area, but the objects' reflectivity do not
generate appreciable echoes (light returns). For example, very dark and opaque objects (as a reference, objects with
1.8% reflectivity may not be detected if placed at distances greater than 9 m; objects with 18% reflectivity may not be
detected if placed at distances greater than 23 m).
• The scanner window is obscured (for example, with a dark cloth) within the limited detection zone, partially or
completely hindering the field of view.
• There are highly reflective surfaces in the scanner area (for example, mirrors, polished surfaces, windows, metal,
etc.) positioned to divert the trajectory of the light beams out of the scanner's reception range.
3.2.6 Limited Detection Capability Zone
If the safety laser scanner is positioned in a limited detection capability zone, the device may not detect an object with low
reflectance located at a distance of 100 mm or less from the safety zone origin (center of the scanner). This is the zone with
limited detection capability.
In this circumstance, it is recommended to make the risk assessment take into account the possibility that an object can
cross a zone with limited detection capability. If possible, responsible personnel must provide an additional solution.

Figure 26. Limited detection capability zone
100 mm
3.2.7 Dust Filtering
Set the Dust Filter Level according to different conditions specific to the application. In general, it is the sensitivity to various
levels of airborne particles that impact the response of the SX Series Safety Laser Scanner detection.
Set the Dust Filter Level to the lowest value that still allows the machinery to work without detecting dust.
• Use a LOW dust filter level (default in the configuration software) in cleaner environments where airborne particles
have little effect on object detection.
• Use a MID dust filter level in environments where some airborne particles are present and can influence object
detection.
• Use a HIGH dust filter level in dirty environments to filter (ignore) detection of airborne particles to ensure that they do
not cause the scanner to detect objects in the zone set when nothing is present. This makes the SX Series Safety
Laser Scanner less sensitive to dust and avoids shutting down the machinery unnecessarily.
The Dust Filter Level setting affects the additional distance that must be applied to the Minimum Safety Distance Calculations
( Minimum Safety (Separation) Distance Formula on p. 35). In addition to the level of airborne particles in the safety laser
scanner's environment, some special lighting conditions also affect the detection sensitivity. These special lighting conditions
are:
• The presence of bright light within ±5° of the detection plane (see Light Interference on p. 30).
• Highly reflective backgrounds within 3 m of the Safety Zone boundary (see Highly Reflective Backgrounds on p. 30).
WARNING: These special conditions require additional distance to be added to the Minimum Safety
Distance calculations to avoid a person or object arriving at the danger zone before the machine shuts off.
This distance also depends on the Dust Filter Level setting.
3.2.8 Anti-interference Coding
Anti-interference coding allows using four different emission modes to minimize interference among scanners working in the
same environment. If scanners can interfere with each other (shine into each other), select a different code for each scanner.
This function is also available for all connected devices in a master/remote configuration. Anti-interference coding is not
available in the SX5-B model.
The scanner scans the surrounding area cyclically at a constant speed. The time for an entire cycle is fixed and is called the
scan cycle time. The scan cycle time depends on the selected scan code.
Select the code on the Detection Configuration screen of the configuration software. The selection of a scan code other
than 0 affects the response time of the relevant device since it changes the scan time. The available scan codes are:
Anti-Interference Code Scan Cycle Time
Scan Code 0 (default) 30 ms
Scan Code 1 30.5 ms
Scan Code 2 31 ms
Scan Code 3 31.5 ms
The software automatically calculates the system response time based on the number of connected devices (master/
remotes), scan cycles, and the selected anti-interference code. This response time is rounded up to the highest integer value
in milliseconds.

3.2.9 Master and Remote Configurations
Each master can support up to three remote scanners. All the machine communications are done with the master, which
then passes on the commands to the remote scanners. If a remote scanner is blocked, a signal travels back up the chain to
the master, which turns off the master scanner's outputs.
Each remote scanner adds a system latency of 10 ms.
Configuration Fastest Response Time (ms)
Master only 62
Master with one remote scanner 72
Master with two remote scanners 82
Master with three remote scanners 92
This worst-case response time can be used in all calculations, but it is really the response time for Remote 3. If the master is
blocked, its outputs would turn off in 62 ms since no latency is added going from one remote to the next or to the master.
3.2.10 Shut-Off Functionality
The Shut-Off function allows energy saving, which can be particularly useful when the scanner is used in battery-powered
applications, such as AGVs.
When the scanner is in Shut-Off status, some of its functions are deactivated, but the device is still active and ready to
restore normal operation when needed.
The configuration software does not allow the user to update the firmware version, change a configuration, or set parameters
(e.g. IP address, password) when the scanner is in Shut-Off status.
The Shut-Off function is enabled or disabled on the Zone Set configuration page of the configuration software (see Zone Set
Configuration on p. 82). When the Shut-Off function is enabled, Zone Set 1 is automatically assigned as the Shut-Off Zone
Set (changes from Zone Set 1 to Shut-Off). The Shut-Off Zone set cannot have any Safety or Warning Zones and the
encoder speed range is set to 0.
When the Shut-Off function is engaged (turned on in the scanner), the SHUT-OFF icon shows on the display for 30 seconds.
After that, the display switches to power safe mode and all LEDs go off.
To restore the scanner to normal operation, change the Zone set. The scanner needs approximately 30 seconds to reactivate
all its functions. During this time, the display shows the RES SHUT-OFF icon. After this re-start time, the display and the
LEDs indicate that the scanner is back to normal operation.
Note: If the Shut-Off function is enabled after Safety and/or Warning Zones have been created for Zone
Set 1, they will be deleted.
Note: When a cluster of scanners is in Shut-Off status, the removal of a remote unit will result in an
INTF18 (topology error) fault. If the cluster topology must be changed, remove the power.
3.3 Positioning Horizontal Safety Zones for Stationary Applications
Height of the Safety Zone Above the Floor or Walking Surface — The Safety Zone should not be located more than 1000
mm above the floor H.
Where H > 300 mm, there is a risk that a person can go undetected. In this case, supplemental guarding may be required.
The minimum allowable height of the Safety Zone (H) is a function of the scanner’s detection capability (resolution) and is
calculated using the following formula:
H = 15 × (d − 50 mm) or H = 15 × (d − 2 in) where
d = the Scanner’s Detection Capability (Resolution)
H = the distance of the Safety Zone above the walking surface
Detection Capability (Resolution) (d) Minimum Height (H)
≤ 50 mm (2 in) 0
70 mm (2.8 in) 300 mm (12 in)
90 mm (3.5 in) 600 mm (24 in)
SX Safety Laser Scanner
www.bannerengineering.com - Tel: + 1 888 373 6767 33
Detection Capability (Resolution) (d) Minimum Height (H)
117 mm (4.6 in) 1000 mm (39 in)
H should not be greater than 1000 mm (39 in)
This ensures detection of a given body part (e.g., thigh, leg, ankle) for a given resolution. For example, a Safety Zone with 70
mm resolution may not reliably detect an ankle (which requires a 50 mm resolution). Thus, the 70 mm resolution Safety Zone
is intended to reliably detect a leg and should be mounted 300 mm or more above the walking surface.
For a given Safety Zone height, the corresponding maximum detection capability (resolution) d can be calculated using the
following formula:
d = (H/15) + 50 mm or d = (H/15) + 2 in
Figure 27. A zone with 70 mm resolution is mounted no lower than 300 mm above the floor
Minimum
300 mm
WARNING:
• Safety Zone height (stationary horizontal fields)
• Where the height of a horizontal Safety Zone is H > 300 mm, there is a risk that a person can go
undetected beneath the field.
• If it is possible for an individual to crawl undetected under the Safety Zone and access the hazard,
install supplemental guarding to prevent this access.
3.4 Minimum Safety (Separation) Distance for Stationary Applications
Response Time Considerations — The SX’s mirror rotates every 30 ms (33.3 scans [revolutions] per second). The safety
outputs will switch off only after an object is detected in the Safety Zone for at least two consecutive scans. The SX’s
minimum response time is therefore 62 ms (2 × 30 ms + 2 ms).
To increase the SX’s reliability in an adverse environments (e.g., with fine airborne particles), increase the number of scans
required before the scanners safety outputs turn off. With each additional scan the response time (Tr) increases by 30 ms.
With K = 1600 mm/s the separation (safety) distance increases by 48 mm per additional scan.
WARNING:
•Scanner Response Time Adjustments
• Failure to follow this recommendation could result in serious bodily injury or death.
• Do not increase the SX’s 62 ms response time for vertically positioned Safety Zones such as work
cell access (Entry/ Exit) or perimeter guarding applications where a person could move quickly
through the Safety Zone without being detected.
SX Safety Laser Scanner
34 www.bannerengineering.com - Tel: + 1 888 373 6767
The Safety Zone must maintain a tolerance of at least 40 mm from any wall or fixed object. This 40 mm value is generally
enough to guarantee normal operation, however according to the real reflectance characteristics of the surface, a higher
value may be necessary. The Teach-In feature of the software automatically applies a tolerance of 100 mm. This can be
changed manually if necessary.
WARNING:
• Determine the correct stop time (T)
• An incorrect stop time can lead to serious bodily injury or death. Be sure to include the stop time of
all relevant devices and controls in the calculations.
• Stop time (T) must include the response time of all devices or controls that react to stop the
machine. If all devices are not included, the calculated Safety distance (S) will be too short.
WARNING:
• Maintain the proper safety distance
• Failure to establish and maintain the minimum safety distance could result in serious bodily injury
or death.
• Locate the Safety Zone far enough from the nearest hazard such that an individual cannot reach
the hazard before cessation of hazardous motion or situation.
3.5 Minimum Safety (Separation) Distance Formula
When all factors that influence the Safety Distance are considered, the formula is:
For US Applications For European Applications
DS = [K × (TS + TR)] + Dpf + ZSM + Zamb where
DS = the safety distance, in mm (inches)
K = 1600 mm per second (63 inches per second) (see note 1 below)
TS = maximum stopping time (sec) of the machine (see note 2 below)
TR = maximum response time (sec) of the Scanner (see note 3 below)
Dpf = Depth penetration factor: The additional distance required by U.S.
standards, such as ANSI B11.19, to prevent a person from encroaching
towards the hazard without being detected.
ZSM = the additional distance needed to account for distance
measurement error.
Zamb = the additional distance needed to account for error due to
reflections from retroreflective surfaces.
S = (K × T) + C + ZSM + Zamb where
S = the minimum distance between the hazard and the Safety Zone. S
is never less than 100 mm (4 in)
K = approach speed (see note 1 below)
2000 mm/s (79 in/s) for S < 500 mm (20 in)
1600 mm/s (63 in/s) for S > 500 mm (20 in)
T = overall system stopping performance in seconds (see note 2 below)
C = an additional distance in millimeters (inches), based on intrusion
towards the hazard prior to actuation of the Scanner. This value is
never less than zero.
ZSM = the additional distance needed to account for distance
measurement error.
Zamb = the additional distance needed to account for error due to
reflections from retroreflective surfaces.
Notes:
1. The OSHA-recommended hand speed constant K has been
determined by various studies, and although these studies
indicate speeds of 1600 mm/s (63 in/s) to more than 2540 mm/s
(100 in/s), they are not conclusive determinations. Consider all
factors, including the physical ability of the operator, when
determining the value of K to be used.
2. TS is usually measured by a stop-time measuring device. If the
machine manufacturer’s specified stop time is used, add at least
20% to allow for possible clutch/brake system deterioration. This
measurement must take into account the slower of the two MPCE
channels, and the response time of all devices or controls that
react to stop the machine (e.g., UM-FA-9A safety module). See
Notice Regarding MPCEs. If all devices are not included, the
calculated safety distance (Ds) will be too short and serious injury
could result.
Notes: The above formula is derived from ISO 13855 (2002).
1. If S is greater than 500 mm, then K = 1600 mm/s can be used
instead of the 2000 mm/s speed, however, if the 1600 mm/s value
is used, then S can never be less than 500 mm.
2. T is the time from the actuation of the sensing function to the
machine's assuming a safe condition, comprising a minimum of
two phases: T = t1 + t2 where
t1 is the maximum time between the actuation of the sensing function and
the output signal switching devices (OSSDs) being in the OFF state. This is
the response time of the SX.
t2 is the maximum response time of the machine, i.e. the time required to
stop the machine or remove the risks after receiving the output signal from
the protective equipment. t2 is influenced by temperature, switching time of
valves, ageing of components, and other factors. t2 is usually measured by
a stop-time measuring device. If the machine manufacturer’s specified stop
time is used, add at least 20% to allow for possible clutch/brake system
deterioration. This measurement must take into account the slower of the
two MPCE channels, and the response time of all devices or controls that
react to stop the machine (e.g., UM-FA-9A safety module). If all devices are
not included, the calculated safety distance (Ds) will be too short and
serious injury could result.

3.6 Reducing or Eliminating Pass-Through Hazards
A pass-through hazard is associated with applications where personnel may pass through a safeguard, such as the SX
Series Safety Laser Scanner (which issues a stop command to remove the hazard), and then continues into the guarded
area. This is common in access and perimeter guarding applications. Subsequently, their presence is no longer detected,
and the related danger becomes the unexpected start or restart of the machine while personnel are within the guarded area.
A pass-through hazard typically results from large safety distances calculated from long stopping times, large minimum
object sensitivities, reach-over, reach-through, or other installation considerations. A pass-through hazard can be generated
with as little as 75 mm (3 in) between the sensing field and the machine frame or hard (fixed) guarding.
Eliminate or reduce pass-through hazards whenever possible. While it is recommended to eliminate the pass-through hazard
altogether, this may not be possible due to machine layout, machine capabilities, or other application considerations.
One solution is to ensure that personnel are continually sensed while within the hazardous area. This can be accomplished
by using supplemental safeguarding, such as described by the safety requirements in ANSI B11.19 or other appropriate
standards.
An alternative method is to ensure that once the safeguarding device is tripped it will latch and will require a deliberate
manual action to reset. This method of safeguarding relies upon the location of the reset switch as well as safe work
practices and procedures to prevent an unexpected start or restart of the guarded machine. The SX Series Safety Laser
Scanner provides a configurable Manual Start/Restart (Latch Output) function for these applications.
WARNING:
•Use of the Banner device for Access or Perimeter Guarding
• Failure to observe this warning could result in serious injury or death.
• If a Banner device is installed in an application that results in a pass-through hazard (for example,
perimeter guarding), either the Banner device or the Machine Primary Control Elements (MPCEs)
of the guarded machine must cause a Latched response following an interruption of the defined
area.
• The reset of this Latched condition may only be achieved by actuating a reset switch that is
separate from the normal means of machine cycle initiation.
WARNING:
•Perimeter guarding applications
• Failure to observe this warning could result in serious injury or death.
• Use lockout/tagout procedures per ANSI Z244.1, or use additional safeguarding as described by
ANSI B11.19 safety requirements or other applicable standards if a passthrough hazard cannot be
eliminated or reduced to an acceptable level of risk.
3.7 Reset Switch Location
Mount the reset switch at a location that complies with the warning and guidelines below. If any hazardous areas are
not in view from the switch location, additional means of safeguarding must be provided. The switch should be protected from
accidental or unintended actuation (for example, through the use of rings or guards).
A key-actuated reset switch provides some operator or supervisory control, as the key can be removed from the switch and
taken into the guarded area. However, this does not prevent unauthorized or inadvertent resets due to spare keys in the
possession of others, or additional personnel entering the guarded area unnoticed. When considering where to locate the
reset switch, follow the guidelines below.
WARNING: Reset Switch Location
When considering where to locate the reset switch, you must follow the guidelines outlined in this section.
If any areas within the guarded area are not visible from the reset switch, additional safeguarding must be
provided, as described by the ANSI B11.19 series or other appropriate standards.
Failure to follow these instructions could result in serious injury or death.
All reset switches must be:
• Outside the guarded area
• Located to allow the switch operator a full, unobstructed, view of the entire guarded area while the reset is performed
• Out of reach from within the guarded area
• Protected against unauthorized or inadvertent operation (such as through the use of rings or guards).
SX Safety Laser Scanner
www.bannerengineering.com - Tel: + 1 888 373 6767 37
Important: Resetting a safeguard must not initiate hazardous motion. Safe work procedures require a
start-up procedure to be followed and the individual performing the reset to verify that the entire hazardous
area is clear of all personnel before each reset of the safeguard is performed. If any area cannot be
observed from the reset switch location, additional supplemental safeguarding must be used: at a
minimum, visual and audible warnings of machine start-up.
3.8 Supplemental Safeguarding
Position the scanner components so an individual cannot reach through the defined area and access the hazard point before
the machine has stopped.
Additionally, the hazard cannot be accessible by reaching around, under, or over the defined area. To accomplish this, install
supplemental guarding (mechanical barriers, such as screens or bars), as described by ANSI B11 safety requirements or
other appropriate standards. Access must only be possible through the defined area of the Scanner or through other
safeguarding that prevents access to the hazard.
The mechanical barriers used for this purpose are typically called hard guarding; there must be no gaps between the hard
guarding and the defined area. Any openings in the hard guarding must comply with the safe opening requirements of ANSI
B11 or other appropriate standard.
WARNING: The Hazard Must Be Accessible Only through the Sensing Field
The installation of the SX must prevent any individual from reaching around, under, over or through the
sensing field and into the hazard without being detected. Mechanical barriers (for example, hard (fixed)
guarding) or supplemental safeguarding may be required to comply with this requirement, and is
described by ANSI B11.19 safety requirements or other appropriate standards. Failure to follow these
instructions could result in serious injury or death.

This shows an example of supplemental safeguarding inside a robotic work cell. The safety light screen, in conjunction with
the hard guarding, is the primary safeguard. Supplemental safeguarding (such as scanners used as area guards) is required
in areas that cannot be viewed from the reset switch (for example, behind the robot and the conveyor). Additional
supplemental safeguarding may be required to prevent clearance or trapping hazards (e.g., the safety mat as an area guard
between the robot, the turntable, and the conveyor).
3.9 Mobile Applications
The SX can protect individuals entering an area with a variable or moving hazard, protect individuals and objects located
within a mobile vehicle’s path, and protect the mobile vehicle and its load from collisions.
Only use the SX on vehicles with electrical drives (e.g. servo) or electrically controlled drive and braking. The Safety Zone
must be configured so that the mobile vehicle can come to a complete stop before a collision can occur. If it is not possible to
completely safeguard the vehicle, including trailers, protruding or overhanging loads, etc., during the full length of travel,
including curves, use additional safeguarding, such as additional SX or bumper/edge switches.
SX Safety Laser Scanner
38 www.bannerengineering.com - Tel: + 1 888 373 6767
The following instructions are general in nature and are intended to provide guidance to safely install the SX on mobile
vehicles. It is not possible to give exact recommendations for all mobile applications; the designer/user must also comply with
the vehicle manufacturer’s recommendations and all applicable regulations and standards. See also the warning and the
basic installation guidelines.
Safety standards covering mobile vehicles or automated/automatic guided vehicles (AGV) include:
• ISO 3691-4 — Industrial Trucks - Safety Requirements and verification - Part 4: Driverless industrial trucks and their
systems
• ANSI/ITSDF (ASME) B56.5 — Safety Standard for Guided Industrial Vehicles
• IEC 61496-3 — Requirements for Active Opto-Electronic Protective Devices Responsive to Diffuse Reflection
(AOPDDR)
The user must also regularly check the safeguarding function of the SX, and the speed and braking functions of the mobile
vehicle (see Initial Checkout on p. 64).
The user must instruct all individuals that may interact with the mobile vehicle (at a minimum) to:
• not approach the vehicle directly or from the sides while moving
• familiarize themselves with warning signals or lights/beacon
• familiarize themselves with the size of the Warning and Safety Zones
3.9.1 Safety Zone Area - Length and Width
The horizontal Safety Zone will prevent a collision only if the edge of the field in the direction of movement is sufficiently
distant from the vehicle and its load. This dimension (length) of the Safety Zone is described as the Minimum Distance D.
The Side Distance Z (or the width of the Safety Zone) is used to ensure that the sides of the vehicle or a protruding load do
not create a hazard.
It is highly recommended that an oversized Warning Zone (in comparison to the Safety Zone) be used. The Warning Zone
and its associated output signal the approach of the mobile vehicle (e.g., by sounding a horn or illuminating lights/beacons),
and reduce the speed of the mobile vehicle. This can reduce the need or the amount of braking and wear on the drive
mechanisms.
The Safety Zone configuration must take into account trapping/crushing hazards that could be created by physical objects
near the path of the mobile vehicle. An example would be an elevated conveyor that the sensing field of the Side Distance Z
passes under, but does not provide enough clearance. This situation can occur if the distance between the end of the
conveyor and the side of the mobile vehicle is less than 500 mm (20 in) per ISO 13854 (EN349) Minimum Gaps to Avoid
Crushing.
The following items apply to the calculation for determining the Minimum Distance D (Safety Zone length):
• Maximum speed of the AGV (Do not rely on the speed reduction initiated by the Warning Zone!)
• The SX response time
• The response time of the mobile vehicle drive logic, including the response time of any interfacing devices, such as
UM-FA-..A safety module (25 ms)
• The braking distance of the AGV (including environmental conditions, such as wet or slippery flooring)
• Absence or lack of clearance in front or to the sides of the AGV
• The speed of movement of an individual
• The reduced efficiency of the braking system, due to wear
WARNING:
•Calculate the correct stop time
• Failure to follow these instructions could result in serious injury or death.
• The Stop Time (TS) must include the response time of all relevant devices or controls that react to
stop the mobile vehicle. If all devices are not included, the calculated Minimum Distance (D) will be
too short.
WARNING:
• Maintain the proper separation distance
• Failure to establish and maintain the Minimum Distance D could result in serious bodily injury or
death.
• Locate the Safety Zone far enough from the nearest hazard such that an individual cannot reach
the hazard before cessation of hazardous motion or situation.

3.9.2 Minimum Distance D (Safety Zone Length) for Mobile
Applications
The following calculations do not specifically take into account the speed of an individual since it can be assumed that an
individual will recognize and will avoid the hazard or at a minimum stop their movement. If this cannot be reasonably
expected, such as if the Warning Zone is not used to signal the approach of the vehicle, the factor ZA should incorporate the
expected speed of an individual.
When all factors that influence a mobile vehicle stopping performance are considered, the formula is: D = DSD + ZSM + Zamb
+ ZF + ZA where:
D = Minimum distance from the vehicle surface to the edge of the Safety Zone in mm
DSD = Stopping distance in mm
ZSM = the additional distance needed to account for distance measurement error.
Zamb = the additional distance needed to account for error due to reflections from retro reflective surfaces.
ZF = the additional distance needed to account for AGV ground clearance
ZA = application specific additions
Note: In the following figure, ZLEAD = ZSM + Zamb + ZF + ZA

where:

VMAX = the maximum velocity as stated by the manufacturer of the mobile vehicle
TS = maximum stop time (in seconds) of the mobile vehicle (see note 1 below)
TR = maximum response time (in seconds) of the Scanner (see note 2 below)
DB = Braking Distance at full load and speed as stated by the manufacturer of the mobile vehicle and other environmental
factors (see note 3 below)
Notes
1. TS for the mobile vehicle should be supplied by its manufacturer. TS must include the response time of all devices or
controls that react to stop the vehicle (e.g., UM-FA-9A Safety Module), which are added to determine the total time to
cause braking/stopping. If all devices are not included, the calculated distance (DSD) will be too short and serious
injury could result.
2. Braking Distance (DB) should incorporate factors such as brake deterioration and environmental factors that can
impact braking (such as loose dirt/gravel, wet/moisture, icing, etc.) which can add 10% or more to the manufacturer’s
stated distance. It should be noted that braking distance is not a linear function; it increases by a square function as
velocity increases.
3.9.3 Additional Distance Factors (Z) Specific for Mobile Applications
For mobile applications, two additional factors must be considered: ZSM and Zamb.
ZSM Measurement Tolerance Factor—For Horizontal Safety Zones (parallel approach): ZSM = 150 mm.

Zamb Retro Reflector Factor—The additional distance needed to account for measurement errors due to light interference
(see section 3.x.4) and/or reflections from highly reflective or shiny surfaces that are present in the scanning plan.
• No ambient interference Zamb = 0
• Ambient Interferences present Zamb = 200 mm; for more information and how to determine the value for the SX5-B
model, refer to Light Interference on p. 30 and Highly Reflective Backgrounds on p. 30
ZF Mobile Vehicle (AGV) Ground Clearance— The additional distance ZF is required if the mobile vehicle does not have
sufficient ground clearance (HF) such that there is no space under the vehicle or Scanner for the tips of feet. If the wheels
are mounted near the side wall, always add an additional distance ZF ≥ 150 mm; otherwise ZF is determined according to the
following figure.

ZA Application-Specific Additions— ZA is the additional distance needed to account for factors that can otherwise affect
the safe application of the SX. Examples include:
• Approach speed of an individual who is unaware of the vehicle's movement. ISO 13855 (Positioning of Safeguard
with Respect to Approach Speed) defines walking speed as 1600 mm/s (63 in/s), thus ZA = 1600 mm/s × (TS + TR)
• Additional clearance to avoid crushing, ZA = 500 mm (20 in) per ISO 13854 (EN349)
• The effect of turning with long vehicles or trailers, resulting in large lateral travel
Multiple factors may or may not result in a cumulative effect: ZA = ZA1 + ZA2 + … ZAn. Evaluate each factor to determine its
effect on all Additional Distance Factors (Z).
Additional Side Distance Z (Safety Zone Width)— The width of the Safety Zone is determined by the width of the mobile
vehicle and the Additional Distance Factors (Z) as described. The distance Z may be different for the two sides and the
leading edge. The width of the Safety Zone must be greater than the width of the mobile vehicle.
Z = ZSM + Zamb + ZF + ZA
It is important that the factor ZA include the effect of turning with long vehicles or trailers, resulting in large lateral travel.
3.10 Mounting System Components
3.10.1 Mounting Your Scanner for Mobile Applications
The mounting of the SX should take into account:
• the surface contour of the path of the vehicle including holes, bumps, inclines, ramps, and other variations in the
surface
• deflection of springs or other vibration dampeners that could cause the plane of the Safety Zone to vary
• unmonitored areas created by the installation of the SX
The point of mounting is typically in the center of the leading edge of the vehicle and is aligned horizontally to achieve a
consistent scanning height over the entire Safety Zone.
Mounting Height— Mount the SX as low as possible to prevent people from passing beneath the sensing field by lying on
the floor. ISO 3691-4 and IEC 61496-3 recommend that the Safety Zone with a resolution of 70 mm be as near as possible to
the floor, but no greater than 200 mm (7.9 in) above the floor. In general, a height of 150 mm (5.9 in) has been recognized by
industry to be the most advantageous height above the floor.

Unmonitored Areas—Mounting the SX on the mobile vehicle must not create unmonitored areas between the Safety Zone
and the vehicle, such that the SX cannot respond to an object with a cross-section of 70 mm or more. Unmonitored areas on
a mobile vehicle can be prevented by:
• Design/contour of the mobile vehicle
• Position of the Scanner
• Mounting the Scanner recessed within the vehicle
• Mounting the Scanner under a physical guard or overhanging parts of frame
• Using supplemental safeguarding, such as bumper or edge switches
• Using mechanical barriers to prevent access
3.10.2 Mounting the Scanner Directly to a Surface
The device has two M5 threaded holes on each side. For direct mounting, use both M5 threaded holes on a given side,
taking into account the following values:
• M5 on the back (tightening torque of 2.3 to 5.5 N·m), maximum depth of thread engagement 9.5 mm
• M5 on the side (tightening torque of 2.3 to 3 N·m), maximum depth of thread engagement 8 mm
Important: For direct mounting on the sides, if the wall or panel obstructs the output window, this plane
cannot be used for safety zone monitoring. The safety zone must adhere to the minimum distance to wall
value.
Figure 33. Mounting the scanner directly to a surface
The M5 UNI 5933 screws used for mounting the brackets to a wall are not supplied in the bracket mounting kits; they must be
supplied by the user.
If the direct mounting procedure to the back is chosen, it is not possible to add the protection bracket to the device.

2Bracket Mounted
The SXA-MBK-2 protection bracket is an optional accessory that
provides protection to the scanner if it is located in an environment
where the scanner may be hit by falling objects or subject to
collision.
Fasten the protection bracket (1) on the back of the scanner using
two M5 screws (2) (maximum of 3 N·m torque). Mount the SXA-
MBK-2 bracket onto the scanner before installing the other
mounting accessories.
Important: This protection bracket consumes
the mounting holes on the back of the unit. Use
other holes to mount the scanner to the
machine.
3.10.4 Mounting the Angle Adjustment Brackets
Provide two M5 holes with 73 mm spacing on the intended wall or mounting surface. The M5 UNI 5933 screws used for
mounting the brackets to a wall are not supplied in the bracket mounting kits; they must be supplied by the user.
Pitch and roll angle adjustment bracket (SXA-MBK-1)—The bracket system is partially assembled.
1. Remove the M4 roll adjustment screws and washers (7), then align the M5 wall mounting screws (9).
2. Mount the roll adjustment bracket (8) to the wall or panel by inserting two M5 UNI 5933 screws (9). Tighten them,
alternating between the two, until they are tight (torque to 2.5 to 3 N·m).
3. Place the assembly of (1) and (6) back onto the roll adjustment bracket (8) (or turn back into place) and re-install the
M4 roll adjustment screws and washers (7). Do not tighten the M4 roll adjustment screws for the roll angle.
If only pitch adjustment is desired, the entire
SXA-MBK-1 can be used with the roll
adjustment centered (level) or the back plates
(6 and 8) can be removed and only the pitch
adjustment bracket (1) is used to mount the
scanner. To remove 6 and 8 first remove the
roll adjustment screws (7) to remove the back
plate (8). Then remove the four screws that
attach (6) to (1) from the back.
The pitch adjustment plate (1) can now be
mounted to the 73 mm spaced holes using the
M5 UNI 5933 screws (9). Tighten the screws,
alternating between the two, until they are
tight (2.5 to 3 N·m torque).

3.10.5 Mounting the Scanner and Adjusting the Angle
When mounting the brackets or scanner, do not exceed the listed torque or you will
damage the scanner. The pitch angle adjustment procedure applies to both uses of
the bracket assemblies.
The Positioning Memory Bracket (one piece) saves the inclination angle set for the
installation. This allows for quick installation without further mechanical adjustments
if it is ever necessary to replace the unit.
To mount the device with 90° vertical inclination:
1. Mount the Positioning Memory Bracket (3) with the M4 screw (and washer)
(2) to the main bracket (1) but do not tighten it.
2. Align the Positioning Memory Bracket with the center of the main bracket
slot, then tighten the M4 screw (do not exceed 1.5 to 2 N·m torque).
3. Mount the scanner to the main bracket using the M5 × 12 Pitch Adjustment
Screws (with washers) (5) and the M5 × 12 Scanner Fastening Screws (4).
Tighten all four screws (do not exceed 2.5 to 3 N·m torque).
To place a device with a specific pitch angle:
1. Screw without tightening the M5 Scanner Fastening Screws, the M5 Pitch
Adjusting Screws, and the Positioning Memory Bracket with the M4 screw.
2. Rotate the device to the desired pitch angle within the allowed range (± 6°).
3. Tighten the M5 Scanner Fastening Screws and then the M5 Pitch Adjusting
Screws (do not exceed 2.5 to 3 N·m torque).
4. Tighten the Positioning Memory Bracket M4 screw (do not exceed 1.5 to 2
N·m torque).

3.10.6 Adjusting the Roll Angle
The roll angle adjustment procedure only applies when all parts of
bracket SXA-MBK-1 are used. Rotate the brackets to reach the
desired roll angle within the allowed range (± 8.5°). Tighten the M4
Roll Adjusting Screws (7) (do not exceed 1.5 to 2 N·m torque) .

axis.
3.10.8 Mounting and Unmounting the Removable Memory
On Master units, the machine interface cables are connected to the Removable Memory (memory device) mounted on the
bottom of the scanner. The following procedure describes how to access this removable memory device to connect the
machine interface cables.
A 2.5 mm hex key is needed for this process. The use of an adjustable torque driver is preferred to prevent overtightening
any of the screws and damaging the scanner housing.
1. Gently place the scanner on its top to expose the underside of the scanner.
2. With the 2.5 mm hex key, remove the black cover by loosening the two screws until the cover comes free.
The screws in the cover are captive screws and should not be removed from the cover.
3. With the 2.5 mm hex key, loosen the two screws of the removable memory device.
The removable memory device is connected to the scanner with captive screws. Only loosen the screws. They do not
and should not be removed.
SX Safety Laser Scanner

4 Electrical Connections
WARNING:
• Make the proper electrical connections
• Connecting equipment to the SX other than what is described in this manual could result in serious
bodily injury or death.
• Make no more connections to the SX than are described in this manual.
• Electrical connections must be made by Qualified Personnel and must comply with NEC (National
Electrical Code) and local standards.
Lockout/tagout procedures may be required (refer to OSHA 29CFR1910.147, ANSI Z244-1, or the appropriate standard for
controlling hazardous energy). Following relevant electrical standards and wiring codes, such as the NEC, NFPA79 or
IEC60204-1, always connect ground (red wire, see wiring diagrams).
4.1 Routing Cordsets
Connect the SX to the machine interface through the appropriate M12/Euro-style machine interface connector(s) using color-
coded cable wiring according to safety equipment regulations. Banner provides accessory cables with color-coded wiring
(referenced in this manual) in compliance with the regulations and standards.
Attach the required cordsets to the SX and route the Machine Interface cable to the junction box, electrical panel, or other
enclosure in which the safety module or other safety related parts of the control system are located. This must be done per
local wiring code for low-voltage dc control cables and may require installation of electrical conduit. For information on
Banner's accessory cables, see Accessories on p. 114.
Attach the 4-pin M12 ethernet cable if it is to be permanently installed. If the connection is only to be used during
configuration (and troubleshooting), route the cable to the PC such that it does not interrupt the scanning field. After the
configuration is complete, remove the PC interface cable and replace the dust cover.
The SX is designed and manufactured to be highly resistant to electrical noise and to operate reliably in industrial settings.
However, extreme electrical noise may cause a random Trip or Latch condition. In extreme cases, a Lockout is possible. SX
wiring is low voltage; routing the cables alongside power wires, motor/servo wires, or other high voltage wiring may inject
noise into the SX.
It is good wiring practice (and may be required by code) to isolate the SX cables from high-voltage wires, avoid routing
cables close to noisy wiring.
Important: The standard SXA cables are unshielded cables. If shielded cables are used, provide a good
earth ground connection to the cordset shield.
4.2 Initial Electrical Connections
Note: The scanner's external power supply must be capable of bridging a brief power failure of 20 ms, as
per IEC 60204-1.
Note: A functional earth ground is available. See Machine Interface Connections for the Stand-alone
Models on p. 51, Machine Interface Connections for the Master Models (8-pin) on p. 55, Machine
Interface Connections for the Master (12-pin) on p. 56, or Machine Interface Connections for the Master
(17-pin and 17+8-pin) on p. 60.The user can connect it or leave it floating to achieve in the application a
best compliance with electromagnetic interferences.
Ensure that electrical power is not applied to the SX until told to do so. Do not connect any wires to the machine control
circuits (i.e. OSSD outputs) at this time.
For initial power-up and checkout, connect as described (to find the pin numbers and wire colors, refer to the appropriate
machine interface wiring section for the model of scanner being used):
• Power connections
• Reset and Zone Set inputs
• If EDM has been configured, it must be wired. Wire the OSSDs to the relays/contactors but do not wire the relay
outputs to the machine. Wire the NC contacts to the EDM pin selected in the configuration.
After configuring the SX and performing the initial checkout procedure:
• Make the final connection of the OSSD and warning (if used) outputs
• Refer to the installation instructions of any interfacing device (i.e. UM-FA-9A/11A) for proper connection and
checkout.
SX Safety Laser Scanner
www.bannerengineering.com - Tel: + 1 888 373 6767 47
If used, connect the external reset switch to the reset wire of the machine interface cordset and to 24 V DC. See warning
about the physical location of the reset switch in Reset Switch Location on p. 37. The reset switch must be a normally open
switch that is held closed for approximately 0.5 to 4 seconds, and then re-opened to accomplish the reset. The switch must
be capable of switching 10 to 30 V DC at 30 mA.
If used, connect the area switch inputs to the configured pins. This must be done to verify each Zone Set.
4.3 Electrical Connections to the Guarded Machine
WARNING:
•Risk of electric shock
• Use extreme caution to avoid electrical shock. Serious injury or death could result.
• Always disconnect power from the safety system (for example, device, module, interfacing, etc.),
guarded machine, and/or the machine being controlled before making any connections or
replacing any component. Lockout/tagout procedures might be required. Refer to OSHA
29CFR1910.147, ANSI Z244-1, or the applicable standard for controlling hazardous energy.
• Make no more connections to the device or system than are described in this manual. Electrical
installation and wiring must be made by a Qualified Person 8 and must comply with the applicable
electrical standards and wiring codes, such as the NEC (National Electrical Code), NFPA 79, or
IEC 60204-1, and all applicable local standards and codes.
Verify that power has been removed from the SX and the machine/vehicle to which it will connect. Make the electrical
connections described as required by each individual application.
Lockout/tagout procedures may be required (refer to OSHA CFR 1910.147, ANSI Z244-1, or the appropriate standard for
controlling hazardous energy). Follow relevant electrical standards and wiring codes, such as the NEC, NFPA79 or IEC
60204-1.
The connections for supply power, external reset (if used), external device monitoring (EDM) (if used), and Zone Set area
switch inputs (if used) should already be connected. The SX must also have been configured, mounted and passed the initial
checkout, as described in Initial Checkout on p. 64.
The final connections to be made are:
• OSSD outputs
• Warning Auxiliary (if used)
• FSD/MPCE Interfacing
• Mute Sensor inputs (if used)
• Mute Enable input (if used)
• Mute Lamp output (if used)
• Override input (if used)
4.3.1 Connecting the OSSD Outputs
Both halves of each pair of output signal switching device (OSSD) outputs must be connected to the machine control so that
the machine’s safety-related control system interrupts the circuit or power to the machine primary control element(s) (MPCE),
resulting in a non-hazardous condition.
Final switching devices (FSDs) typically accomplish this when the OSSDs go to an OFF state. Refer to the output
specifications and the warnings below before making OSSD output connections and interfacing the Scanner to the machine.
WARNING:
•Interfacing both output signal switching devices (OSSD)
• Failure to follow these instructions could result in serious injury or death.
• Unless the same degree of safety is maintained, never wire an intermediate device(s) (PLC, PES,
PC) between the safety module outputs and the master stop control element it switches such that
a failure causes a loss of the safety stop command or the failure allows the safety function to be
suspended, overridden, or defeated.
• Connect both OSSD outputs to the machine control so that the machine’s safety-related control
system interrupts the circuit to the machine primary control element(s), resulting in a non-
hazardous condition.

Note:
•Properly interface the output signal switching devices (OSSD)
•Failure to properly interface the OSSD Outputs to the guarded machine could result in
serious injury or death.
• To ensure proper operation, the Banner device output parameters and machine input parameters
must be considered when interfacing the Banner device OSSD outputs to machine inputs. Machine
control circuitry must be designed so that the maximum load resistance value is not exceeded and
that the maximum specified OSSD Off-state voltage does not result in an On condition.
4.3.2 Connecting the FSD Interfacing
Final switching devices (FSDs) can take many forms, although the most common are forced-guided, mechanically linked
relays or an interface module. The mechanical linkage between the contacts allows the device to be monitored by the
external device monitoring circuit for certain failures.
Depending on the application, the use of FSDs can facilitate controlling voltage and current that differs from the OSSD
outputs of the SX. FSDs can also be used to control an additional number of hazards by creating multiple protective stop
circuits.
Protective Stop (Safety Stop) Circuits
A protective stop allows for an orderly cessation of motion for safeguarding purposes, which results in the stopping of motion
and removal of power from the MPCEs (assuming this does not create additional hazards). A protective stop circuit typically
comprises a minimum of two normally open (N.O.) contacts from forced-guided, mechanically linked relays, which are
monitored (via external device monitoring) to detect certain failures in order to prevent the loss of the safety function. Such a
circuit can be described as a safe switching point.
Typically, protective stop circuits are either single-channel, which is a series connection of at least two N.O. contacts; or dual-
channel, which is a separate connection of two N.O. contacts. In either method, the safety function relies on the use of
redundant contacts to control a single hazard (if one contact fails ON, the second contact will arrest the hazard and prevent
the next cycle from occurring).
The interfacing of the protective stop circuits must be accomplished so that the safety function cannot be suspended,
overridden, or defeated, unless accomplished in a manner at the same or greater degree of safety as the machine’s safety-
related control system that includes the SX.
The normally open safety outputs from a safety module provide a series connection of redundant contacts that form
protective stop circuits for use in either single-channel or dual-channel control.
Dual-Channel Control
Dual-channel control provides the ability to electrically extend the safe switching point beyond the FSD contacts. With proper
monitoring, this method of interfacing is capable of detecting certain failures in the control wiring between the safety stop
circuit and the MPCEs. These failures include a short circuit of one channel to a secondary source of energy or voltage, or
the loss of the switching ability of one of the FSD outputs. Such failures could lead to the loss of redundancy — or to a
complete loss of safety, if not detected and corrected.
The possibility of a failure to the wiring increases as the physical distance between the FSD safety stop circuits and the
MPCEs increases, as the length or the routing of the interconnecting wires increases, or if the FSD safety stop circuits and
the MPCEs are located in different enclosures. For this reason, dual-channel control with EDM monitoring should be used in
any installation where the FSDs are located remotely from the MPCEs.
Single-Channel Control
Single-channel control uses a series connection of FSD contacts to form a safe switching point. After this point in the
machine’s safety-related control system, failures can occur that would result in the loss of the safety function (such as a
short-circuit to a secondary source of energy or voltage).
For this reason, single-channel control interfacing should be used only in installations where FSD safety stop circuits and the
MPCEs are mounted within the same control panel, adjacent to each other, and are directly connected to each other; or
where the possibility of such a failure can be excluded. If this cannot be achieved, then dual-channel control should be used.
Methods to exclude the possibility of these failures include, but are not limited to:
• Physically separating interconnecting control wires from each other and from secondary sources of power.
• Routing interconnecting control wires in separate conduit, runs, or channels.
• Locating all elements (modules, switches, and devices under control) within one control panel, adjacent to each
other, and directly connected with short wires.
• Properly installing multi-conductor cabling and multiple wires through strain relief fittings. (Over-tightening of a strain-
relief can cause short-circuits at that point.)
SX Safety Laser Scanner
www.bannerengineering.com - Tel: + 1 888 373 6767 49
• Using positive-opening or direct-drive components, installed and mounted in a positive mode.
4.3.3 Machine Primary Control Elements and External Device
Monitoring
A machine primary control element (MPCE) is an "electrically powered element that directly controls the normal operation of
a machine in such a way that it is the last element (in time) to function when machine operation is to be initiated or arrested"
(per IEC61496-1). Examples include motor contactors, clutch/brakes, valves, and solenoids.
Depending on the level of risk of harm, it may be required to provide redundant MPCEs or other control devices that are
capable of immediately stopping the dangerous machine motion, irrespective of the state of the other. These two machine
control channels need not be identical (they could also be diverse redundant), but the stop time performance of the machine
(Ts, used to calculate the safety distance, see Minimum Safety (Separation) Distance Formula on p. 35) must take into
account the slower of the two channels. See Wiring Diagrams on p. 51
To ensure that an accumulation of failures does not compromise the redundant control scheme (i.e., cause a failure to
danger) a method to verify the normal functioning of MPCEs or other control devices is required. The SX5-B model provides
this function only when configured for manual start/restart (reset) with MPCE monitoring contacts wired in series with the
reset (start/restart) switch as shown in Wiring Diagrams on p. 51 (see also Reset Switch Location on p. 37). The master
scanner models provide a convenient method for this verification: external device monitoring (EDM).
When the SX5-B scanner model is configured for Automatic Start/Restart (Reset) or a master or SX5-B6 scanner is not
configured for external device monitoring (EDM), to properly monitor the MPCEs, an External Device Monitoring (EDM)
function must be provided from outside the scanner. One example using the UM-FA-9A/-11A safety module is shown in
Wiring Diagrams on p. 51. The UM-FA-9A/-11A can be configured for both manual or automatic reset and provide the
required EDM function.
For external device monitoring to function properly, each device must include a normally closed (NC), forced-guided
(mechanically linked) contact that can accurately reflect the status of the device. This ensures that the normally open
contacts, used for controlling hazardous motion, have a positive relationship with the normally closed monitoring contacts
and can detect a failure to danger (e.g. contacts that welded closed or stuck ON).
It is strongly recommended that a normally closed, forced-guided monitoring contact of each FSD and MPCE be connected
to EDM inputs (see Wiring Diagrams on p. 51). If this is done, proper operation will be verified. Monitoring FSD and MPCE
contacts is one method of maintaining control reliability (OSHA/ANSI) and Category 3 and 4 (ISO13849-1).
If monitoring contacts are not available or do not meet the design requirement of being forced-guided (mechanically linked), it
is recommended to:
• Replace the devices so that they are capable of being monitored, or
• Incorporate the EDM function into the circuit as close to the MPCE as possible (e.g., monitor the FSDs), and
• Employ use of well-tried, tested, and robust components, and generally accepted safety principles, including fault
exclusion, into the design and installation to either eliminate, or reduce to an acceptable (minimal) level of risk, the
possibility of undetected faults or failures that can result in the loss of the safety function.
The principle of fault exclusion allows the designer to design out the possibility of various failures and justify it through the
risk assessment process to meet the required level of safety performance, such as the requirements of Category 2, 3 or 4.
See ISO 13849-1/-2 for further information.
WARNING:
• Notice Regarding MPCEs
• Failure to follow these instructions could result in serious injury or death.
• Each of the machine primary control elements (MPCE1 and MPCE2) must be capable of
immediately stopping the dangerous machine motion, regardless of the state of the other. The two
machine control channels need not be identical, but the machine's stop time performance (TS,
used to calculate separation distance) must be based on the slower of the two channels.
WARNING:
•External Device Monitoring (EDM)
• Creating a hazardous situation could result in serious injury or death.
• If the system is configured for “no monitoring,” it is the user’s responsibility to ensure this does not
create a hazardous situation.
4.3.4 Warning (Auxiliary) Output
The stand-alone scanner can have pins 1, 3, or 4 set as a Warning Output(s). One warning output can be selected when one
or two zone sets are configured. Two warning outputs can be selected when one zone set with one safety zone and two
warning zones is configured. These outputs provide a PNP current-souring output (250 mA maximum) that switches ON
when the defined and active warning field is cleared and switches OFF when the active warning field is interrupted.
SX Safety Laser Scanner
50 www.bannerengineering.com - Tel: + 1 888 373 6767
The master or SX5-B6 scanners can have 1 or 2 Warning Outputs assigned (depending on connector selected, 8 pin can
only have 1 output). These outputs can be assigned to pins or not. The state of the output can also be assigned: on low will
turn the output on when the warning field is clear and on high will turn the output on when the warning field is blocked.
4.3.5 Alarm Output (All Models Except SX5-B)
These alarm outputs apply to all scanner models except the SX5-B model.
One or two alarm outputs can be assigned. These outputs can be assigned to pins for a PNP output.
Enabling Alarm 1 will send a signal when the CLEANW2 warning turns on, signifying that the window needs to be cleaned
(outputs still on).
Enabling Alarm 2 will send a signal when any device fault has turned the outputs off.
4.3.6 Preparing for System Operation
After the initial trip test has been performed (see Perform a Trip Test on p. 65), and the OSSD safety output connections
have been made to the machine to be controlled, the SX is ready for testing in combination with the guarded machine.
The operation of the SX with the guarded machine must be verified before the combined SX and machine may be put into
service. To do this, a Qualified Person must perform the Commissioning Checkout Procedure described in Checkout
Procedures on p. 101.
For the SX5-B6 and master model, the Warning and Alarm outputs can be accessed via the Ethernet connection instead of
hardwired.
4.4 Wiring Diagrams
4.4.1 Machine Interface Connections for the Stand-alone Models
All connections are made using the 4-pin M12/Euro-style connector on the front of the unit and the 8-pin M12/Euro-style
pigtail on the back of the unit. Ensure that the dust cover is re-installed on the 4-pin M12/Euro-style connector when the
communication cable is not installed.

The stand-alone models have one OSSD pair and include three configuration signals. These signals allow the user to
configure the scanner with different functions:
• Signaling when a person or an object is in a Warning Zone
• Switching the detection areas using external signals (Area Switch)
• Restarting the device using a Manual reset (restart) and restoring the device after a fault condition (reset)
• Muting the whole safety area and the single line pattern mute dependent override
• Signaling when the scanner has entered an alarm condition

4.4.5 Remote Scanner Connections (8-pin)
To create a scanner network, remote scanners must be attached to the master. The remote scanners are equipped with
rotatable side connectors for the input and output connection. Data and power are received from the previous scanner via
these connectors. The remote can also send data and power to the next remote via these connectors.
Note: It is possible to connect from one to a maximum of three scanners at a time, which produces a chain
of four devices counting the master. Use 8-pin double ended (male to male) cables to connect remote
devices.

Note: Labels on the rotation connectors help identify the in and out connectors.
4.5 Power Supply and PC Connections
All power connections to the Laser Scanner must strictly comply with standard regulations.
The scanner requires a 24 V DC power supply voltage. Power must be supplied in accordance with SELV/PELV per IEC
60204-1 for all the devices electrically connected to the Safety Laser Scanner. Ensure that the scanner is provided with
appropriate electrical fuse protection and ensure that the functional earth system is the same for all the devices connected to
the Laser Scanner.
Note: The safety laser scanner's external power supply must be capable of bridging a brief power failure
of 20 ms, as required by IEC 60204-1.
Note: A functional earth connection is available on all models. This functional earth connection can be
connected or left floating to achieve the best compliance with electromagnetic interferences for the
application.
Connect the Laser Scanner to a PC for configuration and/or monitoring. The user must create an Ethernet network between
the two devises by employing M12 to RJ45 cables. For more information, see Cordsets on p. 114 and Configuration
Instructions on p. 67.
Note: The scanner must be powered off during any connection operation. Power up the scanner after
connecting it to the computer for configuration.
Note: During configuration, the scanner works using its previously saved configuration.

WARMNG STOP
5 Initial Checkout
The initial checkout procedure must be performed by a Qualified Person, and must be performed only after configuring the
System and after connections are made.
Initial checkout is performed on two occasions:
1. To ensure proper installation when the System is first installed, and
2. To ensure proper System function whenever any maintenance or modification is performed on the System or on the
machinery being guarded by the System.
For the initial checkout, the SX system must be checked without power being available to the guarded machine.
Final interface connections to the guarded machine cannot take place until the SX system has been checked out. This may
require lockout/tagout procedures (refer to OSHA1910.147, ANSI Z244-1, or the appropriate standard for controlling
hazardous energy). These connections will be made after the initial checkout procedure has been successfully completed.
5.1 Apply Initial Power and Configure the SX Scanner System
Verify:
• Power has been removed from (or is not available to) the guarded machine, its controls, or actuators;
• The machine control circuit or the safety module is not connected to the OSSD outputs at this time (permanent
connections will be made later);
• The ethernet cable (4-pin M12/Euro-style to RJ45 cable) is connected to the SX's 4-pin Ethernet connector (if not
previously accomplished) and connect the RJ45 to the PC ethernet port.
1. On the computer, launch the configuration software.
2. Apply power to the SX system.
3. If not previously completed, configure the SX system as described in Configuration Instructions on p. 67.
The scanner must be powered off during any connection operation. During configuration, the scanner will be working
using its previously saved configuration. Follow all the safety instructions.
4. Optional: Status information can be uploaded (Monitoring) or you can download the configuration to the scanner
(Programming).
5.2 Verify the Optical Field (Initial Verification)
The following is the typical display indication, assuming a Warning Zone is configured.
Status OSSD Output Warning Aux Output
Safety and Warning Zones clear On On
Safety Zone clear, Warning Zone interrupted On Off
Safety and Warning Zones interrupted Off Off

I I STO P
If the display background is white instead of black (and the OSSDs are off) the configuration has been sent to the system but
not accepted.
1. Inspect nearby areas for lights and retro-reflective surfaces.
• If found, attempt to remove, cover, or otherwise prevent the item from being located in the scanner's detection
plane.
• If you are unable to do this, ensure the appropriate distance has been added to the separation distance (see Zamb
light factors in Minimum Safety (Separation) Distance Formula on p. 35).
2. Inspect the installation for unmonitored areas and adjacent scanners.
3. In Run mode, observe the scanner's status display to determine status. If any other indication is shown on the
display, see Diagnostic Notes, Warnings, and Errors on p. 105.
4. Ensure that the scanner is in the Run mode, the Safety and Warning Zones are clear of intrusions, and the scanner's
display shows the Zones are clear (or clear and waiting for a reset).
5. Perform a Trip Test to verify the Safety and Warning Zones.
5.3 Perform a Trip Test
Performing a trip test verifies the Safety and Warning Zone fields.
CAUTION: Ensure that no individuals are exposed to any hazard while verifying the Safety and Warning
Zones.
Note: Although the GUI can assist in monitoring the position of objects and the status of the Safety and
Warning Zones, use the display, when possible, to determine whether or not a zone has been interrupted.
1. Ensure that the SX system is in Run mode, the Safety and Warning Zones are clear of intrusions, and the display
shows one of the following:
Zones are clear; OSSDs are on Zones are clear; waiting for a reset input
2. If a Warning Zone is used and with the guarded machine at rest:
a) Use a test piece that matches the resolution selected for the scanner to interrupt the Warning Zone perimeter.
b) Verify the display shows the yellow warning indication.
c) Remove the test piece and verify the warning indicator returns to the status shown in step 1.
d) Repeat this test along the entire Warning Zone perimeter, paying special attention to needle- and cone-shaped
areas.
Yellow warning indication
3. Use the test piece to interrupt the perimeter of the Safety Zone.
The display when a test piece interrupts the Safety Zone
4. Remove the test piece and verify the display returns to the green Go display shown in step 1.
5. Repeat this test along the entire Safety Zone perimeter and verify that the configured zone:
SX Safety Laser Scanner
www.bannerengineering.com - Tel: + 1 888 373 6767 65
• Responds to the intrusion of the test piece.
• Has no unmonitored areas as described in Unmonitored Areas on p. 27.
• Complies with the Safety Distance calculated in Minimum Safety (Separation) Distance Formula on p. 35.
Pay special attention at needle- and cone-shaped areas.
6. For stationary applications, verify that the marking of the perimeter of the Safey Zone on the floor corresponds with
the status of the display. If the floor has not been marked, do so now, with the aid of the display response.
7. Verify the height of the Safety Zone at the perimeter is at the expected level (for example, 150 mm for mobile
applications):
• Safety Zones of 180 ° to 275°—Verify the height in at least four locations, approximately 90° apart from each
other.
• Safety Zones of 90° to 180°—Verify the height in at least three locations, approximately 90° apart from each
other.
• Safety Zones of 90° or less—Verify the height in at least two locations, approximately 90° apart from each other
Figure 47. Safety Zone angles and locations for verification Figure 48. Safety Zone height

8. If Zone Set switchover is used, repeat steps 1 through 7 for each Zone Set that has been configured. Ensure all fields
correspond to the expected fields as determined by the risk assessment. If not, do not continue until the situation
is corrected.
9. If remote scanners are part of the configuration, repeat steps 1 through 8 for each Zone Set of each remote scanner
that has been configured. Ensure all fields correspond to the expected fields as determined by the risk assessment. If
not, do not continue until the situation is corrected.
10. After all corrections and changes to the configuration and the Safety and Warning Zones have been verified, proceed
to Electrical Interface to the Guarded Machine.
WARNING:
•Trip test failure
• Using a system that has failed a trip test can result in serious bodily injury or death. If the trip test
has failed, the system might not stop dangerous machine motion when a person or object enters
the sensing field.
• Do not attempt to use the system if the system does not respond properly to the trip test.
Other checks to carry out include:
• Performing system checkouts to ensure the continued reliable operation. Banner Engineering highly recommends
performing the system checkouts as described in the checkout procedures. However, a Qualified Person should
evaluate these recommendations, based on the specific application and the results of a machine risk assessment, to
determine the appropriate content and frequency of checkouts.
• Designing the Safety Zone so that the approach towards any dangerous point of the machine can only be accessed
by passing through the Safety Zone, and the distance that a person has to cover must be longer than the minimum
safety distance.
• Ensuring a person is unable to remain between the Safety Zone and the dangerous parts of the machine undetected.
• Ensuring access to the dangerous areas of the machine is not possible from any unprotected area.
• Documenting safety checks in a traceable manner.
• Immediately shutting down the machine if the safety check session reveals hypothetical faults. The electrical and
mechanical installation must be checked for further verifications by qualified personnel.

6 Configuration Instructions
6.1 System Configuration Settings
The Scanner must be configured by the user to satisfy the requirements of your application.
Use the SX's configuration software to establish the SX operating parameters. Download the configuration software from
www.bannerengineering.com.
The software is the SX's configuration tool, providing several important advantages:
• Intuitive Graphical User Interface for rapid configuration
• Defined configuration directly stored in the device
• Discovery and IP address setting features to facilitate remote configuration
• Device Monitoring
The software can be used with a SX connected or offline (without a SX). A configuration can be saved and downloaded to a
SX at a later time.
6.1.1 Response Time and Scan Cycle Setting
The response time of the scanner is the time from when an object enters the Safety Zone to when the OSSD goes to the
OFF state. The scanner scans cyclically with a constant speed and it requires 30 ms to complete one rotation.
The minimum response time of the scanner is 62 ms, which is the time needed by the scanner to make two rotations (scans).
Select the number of scans (and therefore the response time) using the configuration software. The user may enter response
times from 62 to 1202 ms (482 ms for the SX5-B model) in 30 ms increments by changing the number of scans from 2 to 40
(16 for the SX5-B model).
Adding remote scanners to the configuration affects the response time. Each remote scanner adds 10 ms to the response
time for that scanner. A system with a Master and one remote scanner results is a best response time of 72 ms for the
remote and 62 ms for the master.
Increase the number of scans if the scanner is operating in a dirty environment caused by floating dust particles (here the
user may need to collect more data, experiment, to prevent inadvertent OSSD off signals from dust).
CAUTION: If the application requires changing the response time, the configuration may require changes
to the Safety Zone (making it bigger) or changes in the scanner installation.
Default setting: 62 ms (2 scans)
6.1.2 Automatic or Manual Start/Restart
Depending on the number of zone sets being used in the configuration, the Qualified Person can select an Automatic Start/
Restart (trip output) or a Manual Start/Restart (latch output). This setting determines if the SX enters Run mode automatically
or if a manual reset is required first.
Select automatic or manual start/restart using the configuration software.
If Automatic Start/Restart is selected, the OSSD outputs turn on after power is applied, and the SX passes its internal self-
test and recognizes that the Safety Zone is clear. The OSSD outputs also turn on after the Safety zone clears following a
blockage. When the SX is set for Automatic Start/Restart, other measures must be taken to prevent a pass-through hazard.
For mobile applications, ISO 3691-4 requires a two (2) second restart delay after the Safety Zone becomes clear before the
OSSDs turn back on. This delay is meant to allow an individual to fully clear the area protected by the scanner. For mobile
applications, set the Recovery Time for at least 2000 ms.
If Manual Start/Restart is selected, the SX requires a manual reset for the OSSD outputs to turn on when power is applied
and the safety zone is clear. The manual Restart switch must be pressed for at least 500 ms.
WARNING:
•Use of automatic (trip) or manual (latch) start/restart
• Failure to follow these instructions could result in a serious injury or death.
• Applying power to the Banner Engineering Corp. device, clearing the defined area, or resetting a
latch condition must not initiate dangerous machine motion. Design the machine control circuitry
so that one or more initiation devices must be engaged to start the machine (a conscious act), in
addition to the Banner Engineering Corp. device going into Run mode.

PD
WARNING:
•Start/Restart (Reset) Switch Location
• Failure to follow these instructions could result in serious injury or death.
• The system Start/Restart (Reset) switch must be accessible only from outside, and in full view of,
the hazardous area. Reset switches must also be out of reach from within the safeguarded space,
and must be protected against unauthorized or inadvertent operation (via rings, guards, key or
other means). If any areas are not visible from the reset switch, additional means of safeguarding
must be provided.
6.2 Muting Functions
To mute the primary safeguard appropriately, the design of a muting system must:
• Identify the non-hazardous portion of the machine cycle.
• Select the proper muting devices.
• Include proper mounting and installation of those devices.
The SX Series Safety Laser Scanner is equipped with Integral Muting that can monitor and respond to redundant signals that
initiate the mute. The mute automatically suspends the safeguarding function to allow an object to pass through the Safety
Zone, without generating a stop command. The muting function allows the suspension of the entire Safety Zone (Total
Muting) or just part of the Safety Zone (Partial Muting). The muting function can be activated for the safety zone controlling
OSSD1 and/or OSSD2 (OSSD3 cannot be muted).
The mute may be triggered by a variety of external devices. This feature provides a variety of options to tailor the system to
the requirements of a specific application. A pair of muting devices must be triggered within time selected in the configuration
(the maximum delay between the activation of mute 1 and mute 2 can be set for one second to 16 seconds, with the default
time being four seconds) of each other, but the order does not matter. The mute sensors cannot activate simultaneously.
This reduces the chance of common mode failures or defeat.
WARNING: Muting Limitations— Muting is allowed only during the non-hazardous portion of the
machine cycle (ISO 13849-1 and ANSI B11.19). Muting at power up cannot be configured in this scanner.
WARNING:
•Muting Inputs Must Be Redundant
• Failure to follow these instructions could result in serious injury or death.
• Do not use a single switch, device, or relay with two normally open (N.O.) contacts for the mute
inputs. A single device, with multiple outputs, may fail so that the system is muted at an
inappropriate time. This could result in a hazardous situation.
6.2.1 Mute Devices
The beginning and end of a mute cycle must be triggered by outputs from the muting devices, depending on the application.
The mute devices must either have normally open contacts or have PNP outputs, both of which fulfill the muting device
requirements. These contacts must close (conduct) when the switch is actuated to initiate the mute and must open (non-
conducting) when the switch is not actuated or in a power OFF condition.
The SX Series Safety Laser Scanner with Integral Muting monitors the mute devices to verify that their outputs turn on within
the selected time of each other (order does not matter). If the inputs do not meet this simultaneity requirement, a mute
condition will not occur. The mute devices must stay on (conducting) during the entire muting process.
The mute devices should be powered from the same power supply powering the scanner. Several types and combinations of
mute devices can be used, including but not limited to: limit switches, photoelectric sensors, positive-driven switches,
inductive proximity sensors, and 'whisker' switches.
6.2.2 Mute Device Requirements
The muting devices must, at a minimum, comply with the following requirements:
1. There must be a minimum of two independent hard-wired muting devices.
2. The muting devices must have one of the following: normally open contacts, PNP outputs (both of which must fulfill
the input requirements listed in the Specifications), or a complementary switching action. At least one of these
contacts must close when the switch is actuated, and must open (or not conduct) when the switch is not actuated or
is in a power-off state.
SX Safety Laser Scanner
68 www.bannerengineering.com - Tel: + 1 888 373 6767
3. The activation of the inputs to the muting function must come from separate sources. These sources must be
mounted separately to prevent an unsafe muting condition resulting from misadjustment, misalignment, or a single
common mode failure, such as physical damage to the mounting surface. Only one of these sources may pass
through, or be affected by, a PLC or a similar device.
4. The muting devices must be installed so that they cannot be easily defeated or bypassed.
5. The muting devices must be mounted so that their physical position and alignment cannot be easily changed.
6. It must not be possible for environmental conditions, such as extreme airborne contamination, to initiate a mute
condition.
7. The muting devices must not be set to use any delay or other timing functions unless such functions are
accomplished so that no single component failure prevents the removal of the hazard, subsequent machine cycles
are prevented until the failure is corrected, and no hazard is created by extending the muted period.
6.2.3 Examples of Muting Sensors and Switches
Photoelectric Sensors (Opposed Mode)
Opposed-mode sensors, which initiate the muted condition when the beam path is blocked, should be configured for
dark operate (DO) and have open (non-conducting) output contacts in a power OFF condition. Both the emitter and
receiver from each pair should be powered from the same source, to eliminate common mode failures.
Photoelectric Sensors (Polarized Retroreflective Mode)
The user must ensure that false proxing (activation due to shiny or reflective surfaces) is not possible. Banner LP
sensors with linear polarization can greatly reduce or eliminate this effect.
Use a sensor configured for Light Operate (LO or N.O.) if initiating a mute when the retroreflective target or tape is
detected (for example, home position). Use a sensor configured for Dark Operate (DO or N.C.) when a blocked
beam path initiates the muted condition (for example, entry/exit). Both situations must have open (non-conducting)
output contacts in a power OFF condition.
Positive-Opening Safety Switches
Two (or four) independent switches, each with a minimum of one closed safety contact to initiate the mute cycle, are
typically used. An application using a single switch with a single actuator and two closed contacts could result in an
unsafe situation.
Inductive Proximity Sensors
Typically, inductive proximity sensors are used to initiate a muted cycle when a metal surface is detected. Due to
excessive leakage current causing false ON conditions, two-wire sensors are not to be used. Only three- or four-wire
sensors that have discrete PNP or hard-contact outputs that are separate from the input power can be used.
Note: Typical Entry/Exit is Dark Operate (DO) with through-beam or polarized retroreflective sensors.
Typical Home Position and Power Press applications are Light Operate (LO) or closed switch to mute.
WARNING:
•Avoid hazardous installations
• Improper adjustment or positioning could result in serious injury or death.
• Properly adjust or position the two or four independent position switches so that they close only
after the hazard no longer exists and open again when the cycle is complete or the hazard is again
present.
• The user is responsible for satisfying all local, state, and national laws, rules, codes, and
regulations relating to the use of safety equipment in any particular application. Ensure that all
appropriate agency requirements have been met and that all installation and maintenance
instructions contained in the appropriate manuals are followed.
6.2.4 Mute Enable (ME)
The Mute Enable function allows the user control of the state of a mute condition.
Select Mute Enable 1 or 2 for one of the input signals on the Input Configuration page of the configuration software.
• To enable a mute condition, pull the Mute Enable 1 or 2 pin high (+24 V DC)
• To disable a mute condition, connect the Mute Enable 1 or 2 pin to DC common (0 V DC) or leave it open
The +24 V DC and 0 V DC should come from the same power supply as the SX.
Typical uses for Mute Enable include:
1. Allowing the machine control logic to create a 'window' for muting to begin
SX Safety Laser Scanner
www.bannerengineering.com - Tel: + 1 888 373 6767 69
2. Inhibiting muting from occurring
3. Reducing the chance of unauthorized or unintended bypassing or defeating of the safety system
6.2.5 Mute Lamp Output
The SX's display provides a visible indication that the safety device's safeguarding function is muted.
Under Output Configuration, select a Muting Lamp output. Configure one of the Output Signals as Muting Lamp 1 or 2. The
Muting Lamp 1 or 2 line will pulse on and off +24 V DC when the system is muted.
CAUTION:
•Mute Status Must Be Readily Observable
• Failure to follow these instructions could result in serious injury or death.
• Indication that the safety device is muted should be provided and be readily observable. Failure of
this indication should be detectable and prevent the next mute, or the operation of the indicator
should be verified at suitable intervals.
6.2.6 Mute Time Limit (Backdoor Timer)
The Mute Time Limit (Backdoor Timer) allows the user to select a maximum period of time that muting is allowed to occur.
The Mute Time Limit can be set between 10 and 1080 minutes in 1 minute increments using the configuration software.
The timer begins when the second muting device makes the simultaneity requirement and allows a mute to continue for the
predetermined time. After the timer expires, the mute ends no matter what the signals from the mute devices indicate. An
Override can be performed to clear the obstruction (if configured). For no time limit (infinite time), select a time of 0 minutes.
Factory default setting: 10 minutes
WARNING:
•Selecting the Muting Time Limit (Backdoor Timer)
• It is the user’s responsibility to ensure the Mute Time Limit (Backdoor Timer) setting does not
create a hazardous situation.
• Select an infinite time for the backdoor timer (disabling) only if the possibility of an inappropriate or
unintended mute cycle is minimized, as determined and allowed by the machine’s risk
assessment.
6.2.7 Mute-Dependent Override
Overriding a safeguarding device is the manual interruption or suspension of the normal function of a safeguard under
supervisor control. Typically, an Override is needed to clear an object that is stuck within the SX's Safety Zone, such as in an
entry/exit application.
Overriding a safeguarding device should not be confused with muting, which is the temporary, automatic suspension of the
safeguarding function of a safeguarding device during a non-hazardous portion of the machine cycle. Muting allows for
material to be manually or automatically fed into a machine or process without issuing a stop command.
When Override (or Bypass) is used, the following precautions must be taken:
• Prevent exposure to any hazards during an Override; supplemental safeguarding must be provided per ANSI B11.19,
ANSI/NFPA 79, IEC/EN 60204-1, and ISO 13849-1.
• The means of overriding and visual indication must be provided and be readily observable from the location of the
safeguard.
• The reset, actuation, clearing, or enabling of the safeguarding device must not initiate hazardous motion or create a
hazardous situation.
• Standards require the use of spring return, hold-to-run, devise or secure momentary action push buttons, located so
that it will not be possible to enter the hazardous zone while maintaining the state of the devices.
The SX5 Override function can be configured to be initiated via different methods. In the stand-alone and master models, a
one terminal Single Line Pattern option can be chosen. In the master units with at least a 12-pin cable, a Single Line Pattern
using one terminal can be configured. You can also select a two-terminal configuration based on signal level or signal edges.
For either method, the Override switch(es) must be supervised and must prevent automatic operation. The single terminal
Single Line Pattern requires one normally closed (NC) switch connecting +24 V DC to the Override input pin. The dual
terminal level or edge configuration requires one normally open (NO) and normally closed (NC) switch connecting +24 V DC
to Override 1 and 2 input pins.
Note: The switch connected to override 1 pin should be normally open. The switch connected to override 2
pin should be normally closed.
SX Safety Laser Scanner
70 www.bannerengineering.com - Tel: + 1 888 373 6767
The override input(s) force the SX5 system outputs on but should not start the hazardous motion of the machine. The
machine should also include a momentary machine start switch to initial hazardous motion and stop hazardous motion if
released. Also one or more of the following must be true:
• Motion should be initiated by a hold-to-run or similar device.
• If a portable control station (e.g. an enabling device) with an emergency stop device is used, motion may be initiated
only from that station/device.
• Automatic machine operation must be prevented by limiting range of motion, speed, or power (e.g. only used in inch,
jog, or slow speed modes).
At all times, all emergency stop devices must remain active.
Mute Dependent Override with 8-pin models— The stand-alone and master units connected only via the 8-pin QD only
have one pin for an override. Thus the only option is the Single Line Pattern override input. The initiation of the override
function is not as simple as opening the override switch. The scanner must receiver a specific series of voltage signals to
start the override process. To force the scanners outputs on, the safety zone must be violated and at least one mute sensor
must be blocked (on). At this time, the override switch must be opened and closed three times, for less than one second
each time.

Mute Dependent Override with 12-pin or more models—Other than being able to select the one terminal Single Line
Pattern override configuration, a configuration can also select a two input Level triggered or a two-input Edge triggered
override configuration. The difference between these two override processes is what happens to the override switches once
the override process starts.
Even during the override process, the safety logic will have priority. If the override is active, the OSSDs will still go to the off
state (STOP) if the non-muted/overridden safety areas (areas that do not have the override function selected) detect an
intrusion. The possibility of selection gives the system more flexibility, but it is obviously subject to a risk analysis by the user.

In either configuration, when the override signal is accepted the display will show Override and the OSSD LED will be green.
Mute-Dependent Override function allows the user to manually force the OSSD outputs on for up to the configured maximum
override time (120 seconds). To initiate an override, the scanner's Safety Zone must be violated with the OSSD outputs off
and at least one mute device must be blocked (on). The override function automatically terminates when one of the following
happens:
• The interruptions of the safety zone are cleared (in bidirectional-muting configuration)
• All the mute sensor inputs are de-actuated (switched to the off state) (in a bidirectional-muting configuration)
• The 120 second maximum override time limit has expired
• Either override input returning to their normal state (Override 1 going open or Override 2 going closed) (when
configured for level triggered)
• All the muting sensors are de-actuated and no beams of the Safety Zone are interrupted (in a unidirectional-muting
configuration)
The SX's outputs stay on at the end of the override sequence (assuming the SX's Safety Zone is clear, and it is configured
for Automatic Restart).
CAUTION: Single Line Pattern and Edge Triggered: After the override starts, changing the state of the
override switches has no affect on the override function. Engaging an e-stop or releasing the machine's
hold-to-run switch can be used to stop the process. Conduct a risk assessment to ensure this cannot
create a hazardous situation.
6.2.8 Muting Function T (X) (Bidirectional) or L (Unidirectional)
Selection
The SX has multiple muting configurations. The SX can monitor and respond to muting sensors in the Bidirectional or
Unidirectional configuration.
Configure the directional setting of the muting on the Input Configuration screen. The configuration can also select total
(mute the entire safety zone) or partial (mute just a defined section of the safety zone) muting.
Factory default setting: Bidirectional
Use the X configuration when the SX is mounted vertically and Bidirectional is selected in the configuration. The X
configuration uses two muting sensors (e.g. two pairs of opposed-mode photoelectric sensors as shown below). The crossing
point of the two sensing paths must be on the hazardous side of the Safety Zone.

Use the T configuration when the SX is mounted vertically and Bidirectional is selected in the configuration. The T
configuration uses four muting sensors. For example, four pairs of opposed-mode or retro-reflective photoelectric sensors or
diffuse photoelectric sensors with background elimination, spaced with two on the inside and two on the outside of the Safety
Zone.

Use the L configuration when the SX is mounted vertically and Unidirectional is selected in the configuration. This
configuration is suitable for applications requiring unidirectional movement of objects. This configuration uses two mute
sensors (e.g. two pairs of opposed-mode photoelectric sensors) stationed on one side of the Safety Zone. The muting is
initiated when the two sensors are made within the configured maximum muting activation delay time (order does not matter).
The mute cycle ends when the configured time limit is reached after the first mute sensor clears.

CAUTION: Unidirectional muting should only be used for removing materials from the dangerous area.
6.3 Encoder Functions
In mobile applications, the Safety Zone can change according to the position, direction, and speed of the vehicle. A typical
example is the use of the Safety Laser Scanner on an Automated Guided Vehicle (AGV). If the speed changes, the minimum
safety distance changes accordingly (the faster the movement, the longer the distance since the stopping time goes up).
To meet such requirements, the SX5-ME70 model is equipped with encoder inputs that allow measuring the actual speed of
the vehicle. Speed information is received from two independent encoders through high speed inputs supported by the 8-pin
connector (pins 4, 5, 6, and 8).
The scanner receives the signal sent by the encoders. The scanner uses these signals in conjunction with the Area Switch
inputs to select the appropriate Zone Set (as defined by the configuration) for the AGV situation and speed. To this end,
different Zone Sets must be configured so that each one will be activated by means of the area switch inputs and encoder
speed range. The number of available zone sets depends on the number of available inputs. The maximum number of zone
sets is 70.
When encoders are used in a configuration the following information is needed: Encoder Δ [%] and Encoder 1 / 2 [p/cm]
Encoder Δ [%]—This is the allowable variation in the speed measures collected by Encoder 1 and Encoder 2. The minimum
value is 0%, the maximum value is 45%, the default value is 25%. To calculate the allowable variation for your application,
use the following formula:
((Vmax - Vmin)/Vmin) × 100 where
Vmax = Maximum speed
Vmin = minimum speed
If the Encoder Δ is exceeded, the OSSDs enter the OFF state to stop the vehicle. Exceeding the Encoder Δ is only allowed
within a certain time window, based on the vehicle speed:
• If the vehicle speed is in the range between –10 cm/s and + 10 cm/s, the vehicle will not be stopped, regardless of
how long the Encoder Δ persists.
• If the vehicle speed is in the range between –30 cm/s and -10 cm/s or +10 cm/s and +30 cm/s, the Encoder Δ can be
exceeded for a maximum of 60 seconds.
• If the vehicle speed is in the range ≤ –30 cm/s or ≥ +30 cm/s, the Encoder Δ can be exceeded for a maximum of 20
seconds.
• If the vehicle speed is in the range ≤ –10 cm/s or ≥ +10 cm/s, then different directions of rotation on the encoders are
only tolerated for a maximum of 0.4 second.
SX Safety Laser Scanner
74 www.bannerengineering.com - Tel: + 1 888 373 6767
When the speed measured by the two encoders is not the same, the higher speed value is used as a reference for this
calculation.
Encoder 1/2 [p/cm]—Encoder (1 and 2) pulse number per centimeter. For both encoders, the minimum value is 50 (default)
and the maximum value is 1000. This is based on the number of pulses the encoder supplies per revolution and on the ratio
between the vehicle wheel and the friction wheel on which the encoder is mounted.
Figure 55. Friction wheel and vehicle wheel
Friction Wheel
Vehicle Wheel
To calculate Encoder 1/2 [p/cm], follow this example:
• The vehicle wheel has a diameter of 40 cm.
• The friction wheel on which the encoder is mounted has a diameter of 4 cm.
• The incremental encoder supplies 1000 pulses per revolution.
The circumference of the vehicle wheel is 40 cm × π = 125.66 cm.
One revolution of the vehicle wheel corresponds to 10 revolutions of the friction wheel, and therefore the encoder supplies
10,000 pulses per revolution of the vehicle wheel.
To calculate the Encoder Ratio (EncR) (the number of pulses per centimeter of distance covered by the vehicle), use the
following formula:
EncR = Prev ÷ C where
Prev = pulses per revolution of the vehicle wheel
C = circumference of the vehicle wheel
In this example, the EncR value is 10,000 pulses ÷ 125.66 cm = 79.58 p/cm. In the configuration software, enter the rounded
value of 80 p/cm in the relevant Encoder [p/cm] field. The software calculates the maximum allowed speed based on this
data.
After setting the encoder values, configure the Zone Set switching. This parameter group allows editing the Area Switch input
configuration depending on the number of selected Zone Sets and the Speed Range of each Zone Set.
Area Switch inputs select Zone Sets—If a different input switch coding is configured with the Area Switch inputs, the
relevant Zone Sets will have either overlapping or different Speed Ranges. In this case, all Area Switches must differ by two
input bit states to be valid.
Combination of Area Switch inputs and Encoder Speed range select Zone Sets—On the other hand, if more Area
Switches share the same input switch coding, configure different Speed Ranges for each Zone Set.
To set Valid Speed Ranges for each Zone Set, the user first needs to calculate the maximum and minimum speeds that the
scanner can read. To calculate the maximum speed (Vmax), use the following formula:
SX Safety Laser Scanner
www.bannerengineering.com - Tel: + 1 888 373 6767 75
Vmax = Fmax ÷ EncR where
Fmax = 100,000. This is a fixed value corresponding to the maximum frequency that can be read by the scanner.
EncR = Encoder Ratio, the number of pulses supplied by the encoder per centimeter of distance covered by the vehicle.
To calculate the minimum speed (Vmin), use the following formula:
Vmin = -Fmax ÷ EncR
After calculating the Vmax and Vmin of both encoders, take the lower values as reference. The Speed Ranges of each Zone
Set must not exceed these Vmax and Vmin values.
Example:
EncR 1 ratio = 50 p/cm (Encoder ratio for encoder 1)
Vmax 1 = 100,000 / 50 = 2,000 cm/s
Vmin 1 = -100,000 / 50 = -2,000 cm/s
EncR 2 ratio = 60 p/cm (Encoder ratio for encoder 2)
Vmax 2 = 100,000 / 60 = 1,667 cm/s (selected an EncR of a different value for demonstration)
Vmin 1 = -100,000 / 60 = -1,667 cm/s
Therefore, the maximum and minimum speeds that the Scanner can read equal respectively 1,667 cm/s and -1,667 cm/s.
The Speed Ranges of each Zone Set cannot exceed these values.
The Speed Range values cannot be included within the interval from -10 cm/s to + 10 cm/s. For example, the Speed Range
interval from -50 cm/s to -9 cm/s is not allowed, the interval would need to be -50 cm/s to +10 cm/s to be acceptable.
If the encoder function is disabled after configuring the Zone Sets, the Speed Ranges will be preserved. The user will need to
set valid Area Switch combinations for each Zone Set or re-enable the Encoder function.
To avoid the flickering effect (continuous switching between two different Zone Sets), the user will have to consider a suitable
margin between the speed ranges of different Zone Sets, as illustrated.
Figure 56. High to low speed switch point
Ideal Switching Point
Higher Speed
Lower Speed
The encoder connection cables must be run to each encoder separately and correctly wired to avoid opposite sign phases.

6.6.1 Output Configuration
Figure 59. Output Configuration screen
Output Functions
•OSSD—to select how many OSSD pairs are used for a given configuration. This component is connected to the
machine control system and associated with the Safety Zone. If an object violates the Safety Zone, the OSSD pair
switches to the OFF state effectively shutting down the machine. The possible number of outputs (1, 2, or 3) varies
depending on the connector selection. All OSSD outputs are managed in pairs.
◦1x2 (one pair)—Two pins are automatically assigned to OSSD1/1 and OSSD 1/2; pin assignment varies
depending on connector selection
◦2x2 (two pairs)—Four pins are automatically assigned (if available) to OSSD1/1, OSSD1/2, OSSD 2/1, and
OSSD 2/2
◦3x2 (three pairs)—Six pins are automatically assigned (if available) to OSSD1/1, OSSD1/2, OSSD2/1, OSSD
2/2, OSSD 3/1, and OSSD 3/2
•Warning—to select how many Warning Zones to use for the configuration. This is the area outside the Safety Zone,
where an object can be detected but the device will not switch the OSSDs to the OFF-State. It can be used to light a
warning lamp or sound a siren. Depending on the configuration, a maximum of two Warning Zones can be
configured. Some configurations allow the warning zones to be accessed using the Ethernet connection instead of
hardwired. For each Warning Zone selected, an auxiliary warning output is assigned. If no warning outputs are
assigned, no Warning Zones are created in the configuration.
•Warning x—to select when the warning output should be on (conducting). To activate the warning output when the
warning zone is clear, select On Low. To activate the warning output when the warning zone is blocked, select On
High.
•Alarm 1—enabling Alarm 1 activates the Clean Window device error warning (turns on when CLEANW2 message
shows on the display and the window should be cleaned to avoid entering a lockout condition). Some configurations
allow this output to be accessed using the Ethernet connection instead of hardwired.
•Alarm 2—enabling Alarm 2 activates the Device Error warning (turns on when the unit shuts down because of a fault
warning (any fault that turns the outputs off will trigger this output)). Some configurations allow this output to be
accessed using the Ethernet connection instead of hardwired.
•Auto Reset—enabling the Auto Reset feature results in the scanner automatically attempting to reset itself from an
error condition. The scanner will undergo the reset process every 10 seconds. If the error condition is no longer
present the scanner will resume normal operation. [The Auto Reset function will be inhibited if the scanner locks out
in INTFx more than 5 times within 15 minutes. In this case a power cycle is necessary to reactivate the scanner.]
The next functions can be individually set for OSSD1 and/or OSSD2. OSSD3 cannot be muted.
•Muting—enabling the Muting function allows the scanner to operate under controlled conditions where an object can
pass through the Safety Zone without the scanner's OSSD outputs switching to the OFF-State (see Muting Functions
on p. 68). Dedicated devices (mute sensors) must be connected to the scanner input signals to control this function.
The two possible settings are:
◦Disable—No muting abilities
◦Enable—Muting turned on; enabling muting reduces the number of Zone Sets that can be configured
•Muting Lamp—if the Muting function is enabled, an optional muting lamp can be connected to a scanner output
signal to indicate when the scanner is functioning in the Muted condition. The scanner display will always display that
the scanner is muted during a muting cycle. To add the Mute Lamp function, set the feature to Enable.
SX Safety Laser Scanner
www.bannerengineering.com - Tel: + 1 888 373 6767 81
a...“ a...“ a...”
•Override Status—when the muting function is enabled, enabling the Override Status allows assigning an output
signal to indicate when the safety function has been manually deactivated (forcing the OSSDs on) to clear the safety
zone from a work cycle anomaly.
Output Signals—assigning wires to output signals. The first OSSD pair is automatically assigned to specific pins and can
not be changed. The Multi In/Out pins can be assigned as inputs or outputs depending on the configuration settings. If one of
these pins is set as an output, it can not be used as an input. From the Output Configuration page, the Multi Out pins and
Multi In/Out pins can be assigned as follows (depending on configuration settings):
•No Function—If the pin is to be used as an input or not at all select no function at this time.
•Warning x—Assign the pin as either auxiliary warning output 1 or 2.
•Muting Lamp—Assign the pin as a mute lamp output if muting is selected.
•Alarm x—Assign the pin as either alarm output 1 or 2.
•Override Status—Assign the pin as a override lamp if override is enabled.
•Safety Output—Assign the pin as half of an OSSD output pair is more than one OSSD output pair is selected.

6.6.2 Zone Set Configuration
A Zone Set is the combination of a configured Safety Zone (SZ) and Warning Zone (WZ).
When active, a specific Zone Set has sole control of the safety outputs (OSSD1 and OSSD2) and the Warning auxiliary
output, if set in the configuration. This function is useful to change the safeguarding area in applications in which a hazard is
not continually present or in applications in which speed and stopping distances varies.
Figure 60. Zone Set Configuration screen
Zone Set Number—Selects the number of Zone Sets to use for the configuration. The default value is one Zone Set (no
Area Switching). Add more Zone Sets using the up arrow. The maximum number of Zone Sets depends on model and
connector selected.
Input Delay Max (ms)—Required when at least two Zone Sets are selected; sets the delay to apply between switching from
one Zone Set to another. The input delay allows waiting for the Area Switch inputs to stabilize from their transient states
before accepting the Zone Set. The Zone Set will not switch until the end of the selected time (the time starts when it sees
the first transition), otherwise the activation and deactivation of the inputs could put the device in undesired/invalid and
temporary switching zone input combinations and cause the device to enter the fault state. The minimum (default) input delay
value is 30 ms and can be increased in 30 ms increments.
SX Safety Laser Scanner
82 www.bannerengineering.com - Tel: + 1 888 373 6767
Shut Off Status—Enables or disables the Shut Off function (not available in the SX5-B model). This is an energy savings
feature that tells the scanner to go into sleep mode (display turns off and motor stops). Zone Set 1 becomes Shut Off. This
Zone Set cannot have any Safety or Warning Zones, and the Encoder speed range is set to 0. Coming out of shut off mode
can take about 30 seconds.
Encoder Status—Enables or disables encoders for dynamic applications. This field is only available in scanners that support
encoders (SX5-ME70 with connector 17+8 selected).
These next few fields are only visible (required) if Encoder Status in enabled.
Area Switch Number—Sets the number of Area Switch inputs that are required. This number does not have to match the
Zone Set number because the encoder inputs can be used in conjunction with the area switch inputs to select the Zone Set.
This number can be increased or decreased.
Active Input Number—Sets the number of available Active Inputs. This value can be increased according to the number of
Area Switches.
Encoder Δ (%)—Allowable variation in the speed measures collected by Encoder 1 and Encoder 2. The minimum value is
0%, the maximum value is 45%, and the default value is 25%.
Encoder 1 ÷ 2 (p/cm) - Encoder (1 and 2) pulse number per centimeter. For both encoders, the minimum value is 50 (also
the default value) and the maximum value is 1,000. This value is based on the number of pulses the encoder supplies per
revolution and on the ratio between the vehicles wheel and the friction wheel on which the encoder is mounted.
X ICON (Delete)—Removes selected Zone Set(s); if Zone Set is selected, the Zone Set will be deleted when the 'X'
icon is clicked. This results in the Zone Set Number being reduced by the number of Zone Sets that were just deleted.
Clicking the down arrow of the Zone Set Number also reduces the number of Zone Sets but it will delete the highest
numbered Zone Set (which might not be the Zone Set that needed to be removed).
BINARY ICON (Binary)—Automatically sets the input switch coding. Alternately, you can click the Area Switch boxes
to manually change its state. All Area Switching must differ by two input bit states (or encoder states) to be valid.
CHECK ICON— Validates the Zone Set coding.
If a different input switch coding is configured for each Area Switch, the relevant Zone Sets can have either overlapping or
different encoder Speed Ranges. In this case, all Area Switches must differ by two input bit states to be valid. If more Area
Switches share the same input switch coding, different Speed Ranges must be configured for each Zone Set.
More than one Zone Set can be configured to define either separate or overlapping areas and these can be switched
between using combinations of input signals.
To create a Zone Set, the user must configure it through the scanner's configuration software.
Single Zone Set Configuration
This configuration step allows the user to set the Zone Set parameters.
For this example, the configuration includes only one Zone Set, so it is not necessary to insert or edit any parameters. The
Input Wires parameters do not require any assignments in this situation.
Click the white > to move to the next page.
Multiple Zone Sets Configuration
When more than one Zone Set is used, the Zone Set inputs (area switch inputs) are used to select which Zone Set is active.
External logic (e.g., a PLC) is capable of selecting one of up to 70 (depending on the model) configured Zone Sets stored in
the scanner at any given time.
After the scanner is configured, switching over to or activating an individual Zone Set is controlled by the input pins (area
switch inputs) assigned in the configuration software. The Zone Set selection can also be controlled by the Area Switch
inputs and Encoder input values.
The input combination that makes the Zone Sets change (area switch inputs) must be unique and must not be susceptible to
false external signals (at least two inputs must change).
WARNING:
•Use Zone Set switching to change the area of safeguarding.
• Failure to follow these instructions could result in serious injury or death.
•Changing the Safety/Warning Zone Set from one pair to another must not expose any
individual to a hazard or hazardous situation. Supplemental safeguarding may be required.
SX Safety Laser Scanner
www.bannerengineering.com - Tel: + 1 888 373 6767 83
The conditions for switching Zone Sets must be in accordance with a risk assessment. Machine stopping/braking distances,
scanner system response time (including interfacing devices), machine stop time and other factors that influence the Safety
Distance (minimum distance) and Stopping Distance calculations must be considered to safely use the Zone Set switchover
function.
In applications that incorporate Zone Set switchover, Minimum Distance D and Side Distance Z must be calculated
individually for all Zone Sets. Conditions to allow switching Zone Sets:
• Only one Zone Set can be active after the switchover time; see the Zone Set logic in the configuration software.
• Zone Set switchover is allowed even if there is an intrusion into the active Safety Zone (i.e. OSSDs are off).
• The switchover must be made within the Max Input Delay time selected in the configuration software. The input delay
allows waiting for the Area Switching inputs to stabilize from their transient states before accepting the Zone Set
change. Otherwise the activation and deactivation (bouncing) of the inputs could put the device into undesired or
invalid and temporary switching zone input combinations and therefore cause the device to enter the fault state. The
minimum input delay (default) value is 30 ms. It can be increased in 30 ms increments.
In addition, factors dependent on the risk assessment that may affect the safety circuit integrity level include:
• Analyze the means of selecting Zone Sets with respect to failure modes to ensure that an unintended switchover
does not occur.
• Ensure that selecting/deselecting Zone Sets does not expose any individual to a hazard. Supplemental safeguarding
may be required.
Zone Set Configuration
1. On the Zone Set Configuration screen, set the Zone Set No.
Depending on the model and the other features used, you can use from 1 to 70 different Zone Sets by changing the
number shown to match the number of desired Zone Sets.
When increasing the number of Zone Sets, the warning 'To go on, Zones design will be modified' may display. Click
Ok. The previous settings allow multiple Zone Sets. If a different warning displays, the previous settings must be
changed to use multiple Zone Sets.
2. Set the Input Delay Max (ms).
After more than one Zone Set is selected, this input field is displayed. This allows the setting of the delay applied
between switching from one Zone Set to the next. The input delay allows waiting for the Area Switching inputs to
stabilize from the transient states before accepting the Zone Set change. Otherwise the activation and deactivation of
the inputs could put the device in an undesired or invalid Zone Set state resulting in a potential unsafe or fault
condition. The minimum input delay (default) value is 30 ms. It can be increased in 30 ms increments.
WARNING: Set the Input Delay Max time as low as possible because the scanner will not react
to violations of the new Zone Set's Safety Zone during this Zone Set changeover time.
3. Set the Zone parameters.
This parameter group allows editing the Area Switch input combinations depending on how many Zone Sets are
selected. The number of Area Switches (AS#) equal to the number of unassigned inputs will appear in the graphic.
Manually set the input switch coding by clicking inside the Area Switch boxes for each Zone Set. To be valid, all Area
Switching must differ by two input bit states. It is possible to set the input switch coding with specific function buttons.
• If the configuration includes only one Zone Set, it is not necessary to insert any parameters.
• As more zone sets are added, more area switch inputs are needed (the maximum number of area switch inputs is
8 for 37 to 70 Zone Sets).
• If two Zone Sets are selected, at least two pins must be assigned to the Area Switch function.
• For the SX5-B and SX5-B6 models: If 3 to 6 Zone Sets are selected (in this case no other functions are available),
pins 1, 3 and 4 must be assigned to the Area Switch function.
• For the SX5-B and SX5-B6 models: If 4 to 6 Zone Sets are selected, the ability to switch between Zone Sets is
limited. This limitation is to ensure that two Area Switch inputs must change to switch between Zone Sets. The
software does not obligate changing the Zone Sets sequentially (i.e. Zone Set 1, 2, 3, 4, etc in order), therefore
the user must verify that the selected passage from one Zone Set to another (in any order) guarantees that at
least two Area Switch inputs change signal levels.

6.6.3 Input Configuration
Figure 63. Input Configuration screen
For each OSSD pair configured, define the following parameters under Safety Zone x in the Input Function section.
1. Configure the Restart Mode.
•Automatic—The scanner automatically returns the OSSD pair to the On-State after all detected objects are
removed from the Safety Zone and the configured Recovery Time elapses.
•Manual—The scanner returns the OSSD pair to the On-State after all detected objects are removed from the
Safety Zone and a manual Restart switch (reset push-button) is pressed for at least 500 ms, but no longer than
4.5 seconds.
2. Define the Recover Time.
This parameter is only configured for Automatic Restart Mode. The Recover Time is the time between the object
removal from the Safety Zone and the OSSDs going to the On-State. Select the time to elapse before the OSSD pair
returns to the On-State. The minimum time is 200 ms. This can be increased to 60,000 ms in 1 ms increments.
Default: 200 ms
3. Select EDM to enable the External Device Monitoring (EDM) function.
4. Configure EDM Delay Time (ms).
The time delay provided for the monitored device to go from its open state to its closed state when the OSSD outputs
turn off can be set from 200 to 1000 ms. Default setting is 350 ms.
5. Define the Muting Type.
If muting is not selected, this option is grayed out. The Muting function can be used in two different configurations.
•Bidirectional—Used when objects can pass through the Safety Zone from either direction; requires two or four
muting sensors be connected to the scanner inputs
•Unidirectional—Used when objects can pass through the Safety Zone from only one direction (out of the
hazardous area); requires two muting sensors be connected to the scanner inputs
•M coeff.—If Unidirectional Muting is selected, the M coeff is displayed. The M coefficient is the time delay
multiplier that times out the Muting function after a mute sensor clears (typically mute 1). The M coeff can be set
from 2 to 16. This is the multiplier of the activation delay between the initiation of the two muting sensors. The
maximum amount of time that the system will stay muted after the clearing of mute 1 is M Coeff × Max Inputs
Delay (actual elapsed time between the activation of mute 1 and mute 2).
6. Define the Max Inputs Delay (seconds).
The maximum allowable time delay between activation of mute 1 and mute 2. This parameter can be set from 1 to 16
seconds with the default being 4 seconds. If muting is disabled, this field cannot be adjusted.
SX Safety Laser Scanner
86 www.bannerengineering.com - Tel: + 1 888 373 6767
CAUTION: The maximum input delay is based on the conveyor speed and package length. Set
the delay long enough to ensure only the package is passing through the curtain and short enough
to prevent inappropriate or unintended muting cycles.
7. Define the Timeout (minutes).
This parameter allows the entering of a muting backdoor timer (maximum time to stay muted). The default time limit is
10 minutes. The time limit can be increased from 10 minutes to 1080 minutes in 1 minute increments. For no time
limit, enter 0.
WARNING: Select an infinite time for the Muting Time Limit only if the possibility of an
inappropriate or unintended mute cycle is minimized as determined and allowed by the machine's
risk assessment. The user is responsible to make sure that this does not create a hazardous
situation.
8. Enable or disable Override.
If muting is enabled, an override function can also be enabled. The override allows OSSDs to be manually forced on
to drive an item out of the Safety Zone.
WARNING: Measures must be taken to prevent activation of the mute-depended override function
from a fault or inadvertent operation of the initiating device.
9. Set the Override Mode, if applicable.
The override mode can be selected as Single Line Pattern, Edge, or Level. See Mute-Dependent Override on p. 70
for details on these modes. A correct override input sequence forces the scanner's OSSD outputs ON. The
hazardous motion should not start until the initiation button (or hold to run switch) of the machine is also engaged.
The override time limit is 120 seconds.
10. The Input Signals section, allows the configuration of the Multi In and unused Multi in/out pins depending on the
configuration's needs.
•Reset—The reset input function can be added in Automatic or manual reset mode. The reset input allows
restoring normal operation after a failure lockout (fault) condition, due to system error, without disconnecting the
power.
•Restart 1—The restart input function is only added in manual reset mode. The restart input turns on the OSSD
outputs after the blockage has been removed from the Safety Zone (and at startup).
•Restart 1 Reset—This selection will perform on whichever input is needed at the moment (reset for faults, restart
for manual reset situations).
•EDM—The EDM input function is only added if EDM is set to ON.
•Muting Enable x—A mute enable input may be added if muting is enabled (Output Configuration settings).
•Muting x x—Mute sensor inputs must be added if muting is enabled (Output Configuration settings).
•Override x x—Override inputs must be added if the override function is enabled.
This parameter group assigns the signals of the input functions to the scanner pins. Each pin is also associated with
color-coded cable wiring, according to safety equipment regulations and standards. Previously assigned pins are
grayed out.

6.6.4 Detection Configuration
Use the Detection Configuration screen to define the Safety Zone and Warning Zone parameters.
Figure 64. Detection Configuration screen
Response Time—Configure the response time settings for each scanner in the chain. The default scanner is the master. To
configure the parameters for each remote unit simply click on it so that it is highlighted in the left-hand panel.
• Anti-Interference Coding—If multiple scanners are going to be used in an area, this parameter can select different
scan codes for each scanner to reduce chances of scanner interactions. Changing the coding form zero will slightly
increase the response time. See section 3.2.7 for more information on the Anti-Interference Coding feature.
• Maximum Response Time—This value cannot be changed by the user. It will display the expected worse case
response time based on the various settings of the configuration (anti-coding level, number of scans and cascaded
systems).
The response time of the cluster corresponds to the response time of the safety output of the device that goes into the STOP
condition and the system latency time. If the device that goes into a STOP condition is the master, no system latency must
be added. If a remote goes into a STOP condition, then the latency time (10 ms) must be added for each device to pass the
off signal (if one remote ten 10 ms added for master to respond to the incoming off signal).
Resolution—Configure the resolution section for each scanner and each set of OSSDs selected previously. Safety Zone 1
corresponds to OSSDs 1, Safety Zone 2 corresponds to OSSD 2, and Safety Zone 3 corresponds to OSSD 3. Each scanner
and each OSSD pair can have it own resolution settings.
1. Set the Number of Scans required to validate detection of a Safety Zone intrusion.
This parameter directly affects the Response Time, which is the time from when an object is detected in the Safety
Zone to when the OSSD switches to the OFF-State.
The Response Time (ms) is automatically generated based on the Number of Scans selected. Response time
ranges from 62 ms to 1202 ms (482 ms for the SX5-B models), in 30 ms increments.
2. Set the Resolution (mm).
This parameter sets the scanners detection resolution ability. The resolution does affect the maximum range of the
scanner. The options are 30, 40, 50, 70, and 150 mm resolution (40 mm and 70 mm for the SX5-B model). The
resolution selected will affect the maximum range, which is shown in the graph below the Dust Filter Level.
3. Set the Dust Filter Level.
This parameter must be set according to different conditions specific to the application. In general, it is the sensitivity
to various levels of airborne particles that affect the response of the scanner's detection abilities. Increasing the Dust
Filter Level can increase the Minimum Safety Distance if certain lighting conditions exist. See Dust Filtering on p. 32.
SX Safety Laser Scanner

an.“ an... a...“ as...” as." an...“ Emmi"
CAUTION: Set the Dust Filter Level to the lowest value that still allows the machinery to work
without detections from dust.
• High—Use in dirty environments to filter (ignore) detection of airborne particles from being confused with objects
to detect. The scanner is less sensitive to dust and therefore avoids shutting down the machinery unnecessarily.
• Med—Use in environments where some airborne particles are present and can influence object detection.
• Low—Use in cleaner environments where airborne particles have little effect on object detection.
4. Set these same parameters for the Warning Zone if a Warning Zone output is used.
Important:
In addition to the level of airborne particles in the scanner's environment, some special lighting conditions
also affect the detection sensitivity. These conditions are:
• high reflective backgrounds within 3 meters of the Safety Zone boundary
• the presence of bright light within +/- 5 ° of the detection plane.
Include an additional distance in the Minimum Safety Distance calculations for these cases. See the
graphs in the SX's instruction Manual for these additional distances.

6.6.5 Create or Edit Safety and Warning Zones
Figure 65. Zone Configuration screen
Zones must be created for each scanner in the chain. To select a scanner simply highlight it in the list shown in the left-hand
panel.
A safety zone must be designed for each output configured for each scanner of the system. When multiple outputs are
configured with more than one Zone set configured, Safety Area 2 and Safety Area 3 of all Zone Sets coincide and can only
be modified from Zone Set 1 (or Zone Set 2 if Zone Set 1 is assigned the Shut Off function).
Tools are provided to draw the Safety and Warning Zones. It is possible to select different shapes and different functions to
manage the graphing.

Icon Function
{upside-down box}
Flips the scanner over.
The standard view has the top of the scanner at the center point. Clicking the Upside Down box puts the bottom of the scanner
in the center of the graph. Nothing physically has changed but this allows the graph to match the orientation of the scanner.
When a scanner is attached and any form of Live Monitoring is engaged, this icon can be selected. This causes the scanner to
show any areas of high light input (a reflective surface or light source is being seen by the scanner).
This can assist in removing potential interference sources from the environment. This icon can be used in the Monitoring mode
and in Zone configuration when Live Monitoring is on.
6.6.7 Use Live Monitoring to Assign Safety and Warning Zones
Note: The Live Monitoring On, Use Live Monitoring to Draw Zone, and Show Reflective Object icons are
only available if a scanner is online.
You may use the Live Monitoring function to outline the space the scanner is guarding, then go back and use shapes. Or you
can use the Live Monitoring Area Assignment to set the fields in the detected area, up to the maximum range.
1. Click the icon to enter Live Monitoring mode.
Live Monitoring scans and displays the area surrounding the scanner. The white area is free of obstacles and can be
assigned to a Safety or Warning Zone. The gray areas contain detected obstructions.
2. Select the Safety Zone or Warning Zone in the left pane.
3. Click the Live Monitoring Area Assignment icon to assign the defined area to the selected zone.
6.6.8 Protect a Vertical Area (Reference Points)
When the scanner is mounted to protect a vertical area (up and down), add Reference Points to an edge.
These reference points are positions where something will always be sensed by the scanner (the surface will always be
present). These points are used by the scanner to ensure that it has not come loose from its mounting surface and is
protecting the correct area. A minimum of three reference points must be added. A maximum of 15 reference points can be
added.
1. To add a reference point, highlight Reference Point at the bottom of the list of Zones on the left.
The reference point icon becomes live.
2. Click on the Reference Point icon on the right.
3. Click the locations of the desired Reference Points.
The maximum distance from the scanner that a reference point can be configured is based on the maximum range
for the selected resolution. The Reference Points do not have to be at the edge of the Safety Zone. If the distance to
the reference point changes, the scanner will turn off. So even if the Safety Zone is muted, if the reference point gets
blocked, the outputs turn off. Select the reference points so that they should not be blocked during a muting evolution.

6.6.10 Connect a Scanner to a PC (Discover the Scanner)
Enter Discovery mode to have the software search the PC's network for any connected SXs.
Attach new scanners one at a time to the LAN because they all have the same default IP Address (192.168.0.10). After new
IP addresses have been assigned, multiple units can be attached to the same network.
1. Enter Discovery mode using one of these three methods.
• Click on Programming. After the configuration file is uploaded to the scanner, the software enters Discovery
mode.
• Go to the Scanner > Discovery menu.
• From the Task Selection area, select Modify Safety System Configuration for a scanner on the network.
If a pop-up windows appears asking to allow the configuration software access through the Windows Firewall, click
Accept. If the window does not appear, verify that the firewall is set to allow the configuration software access. If
access is not allowed, the scanner is discovered, but no information can be sent to or received from the scanner.
Note: If at anytime a notice pops up saying 'the scanner is busy' verify that the software has
access through the Windows Firewall.
2. The configuration software displays the device with its own IP Address.
3. Double-click on the scanner to place it in the Device Configuration Panel.
4. Click on the white > in the upper right side on the main panel to proceed.
A pop-up window suggests aligning the IP Address of the device with the computer LAN.
5. Click OK and enter the password (the default password is 'admin').
6. Change the IP Address parameters in the Network Configuration screen to align them with the computer LAN.
Important: The displayed IP address is assigned to the SX. The successive address is also
reserved because both internal micros have their own IP address. For example, if the displayed
Scanner IP address is 192.168.0.10, the successive address of 192.168.0.11 is also assigned and
cannot be used as the computer LAN IP address. If remote scanners are configured to the master,
each remote scanner will reserve the next two IP addresses. For example, remote 1 reserves
192.168.0.12 and 192.168.0.13, remote 2 reserves 192.168.0.14 and 192.168.0.15, and remote 3
reserves 192.168.0.16 and 192.168.0.17.
7. Click OK to accept the new IP Address parameters. When the device enters Offline status, click OK to continue.
The configuration software automatically rediscovers the scanner with the new IP Address.
8. Double-click on the SX to enter Programming.
Aligning IP Addresses
Assuming the Subnet Mask is at the typical default setting of 255.255.255.0, the first three octets of the IP address must
match (192.168.0 of the 192.168.0.10).
Change the scanner's IP address to match the LAN of the PC or change the PC's IP address to match the LAN of the
scanner.
Connect to a Scanner (Point-to-Point)
It is possible to connect a configuration PC directly to a scanner using the Ethernet TCP/IP interface (point-to-point).
1. When connecting and using a scanner with your PC for the first time, see Connect a Scanner to a PC (Discover the
Scanner) on p. 93 to avoid any network conflicts in the Ethernet communications (all scanners have the same default
IP address).
2. Go to the Scanner menu and select Direct Connect. If the scanner is on a distributed network and its IP address is
known, it can be found via this method.
3. In the window that opens enter the scanner's IP address and select OK.
If the scanner is found it (and any connected remote units) will show up in the left-hand panel.

7 Operating Instructions
7.1 Status Indicators
The SX has three buttons, a graphical display, and five status LEDs (located below the display).
The SX has diagnostic LEDs for initial diagnostics. The OFF state and ON state LEDs are below the scanner's display. When
it is not possible to see the display because of the way it was mounted or because it is hidden from the operator's position,
use the software's Monitoring function to check the status.

•Exit—Select Exit and push the square button to exit the menu option
7.3 Resetting the System
Perform system resets and scanner restarts using an external reset switch. If supervisory control of the reset/restart switch is
required, a key switch may be used, with the key kept in the possession of a Designated or Qualified Person.
Using a key switch will also provide some level of personal control, since the key may be removed from the switch. This will
hinder a reset/restart while the key is under the control of an individual, but must not be relied upon solely to guard against
accidental or unauthorized reset. (Spare keys in the possession of others or additional personnel entering the safeguarded
area unnoticed may create a hazardous situation.)
Any Multi-in or Multi-in/out pin can be configured as a reset/restart input if needed in a configuration.
SX Safety Laser Scanner
www.bannerengineering.com - Tel: + 1 888 373 6767 99
The SX requires a manual restart to clear a Start/Restart Interlock condition and resume operation following a stop
command. Internal Lockout conditions also require a manual reset to return to Run mode after the failure has been corrected.
A reset results in the scanner performing all of its startup tests. The scanner will be offline for approximately 40 seconds.
To reset/restart the SX, close the reset/restart switch for 0.5 to 4.5 seconds and then open it. Closing the reset/restart switch
too long causes the sensor to ignore the reset/restart request.
7.3.1 Reset Signal Function
There are two internally controlled states between the stop and restart of the scanner:
• Interlock ON: Device can be restarted to its normal function because the detected object has been removed from the
Safety Zone
• Interlock OFF: Device is off because the object has not been removed from the Safety Zone
The Interlock ON will be signaled by the LED 5 (right LED under the device display) turning amber and the display showing
Restart inside a circle.
The manual reset input must be connected to +24 V dc via a Normally Open switch contact.

8 Checkout Procedures
8.1 Periodic Checkout Requirements
This section lists the schedule of checkout procedures and describes where each procedure is documented. Checkouts must
be performed as described. Results should be recorded and kept in the appropriate place (for example, near the machine,
and/or in a technical file).
Banner Engineering highly recommends performing the System checkouts as described. However, a qualified person (or
team) should evaluate these generic recommendations considering their specific application and determine the appropriate
frequency of checkouts. This will generally be determined by a risk assessment, such as the one contained in ANSI B11.0.
The result of the risk assessment will drive the frequency and content of the periodic checkout procedures and must be
followed.
At every shift change, power-up, and machine setup change, perform the Daily checkout. This checkout may be
performed by a Designated or Qualified Person (see the Daily Checkout Card for the procedure).
Semi-annually, the Scanner and its interface to the guarded machine should be thoroughly checked out. This checkout must
be performed by a Qualified Person (see the Semi-Annual Checkout Card for the procedure). A copy of these test results
should be posted on or near the machine.
When changes are made to the System (either a new configuration of the Scanner or changes to the machine), perform
the Commissioning Checkout.
WARNING:
• Verify the proper operation of this SX Series Safety Laser Scanner
• Failure to verify the proper operation, on a regular basis, can result in undetected problems, which
if not corrected, can result in serious injury or death.
• It is the user’s responsibility to verify proper operation on a regular basis.
Study each procedure in its entirety, to understand each step thoroughly before beginning. Refer all questions to a Banner
applications engineer (see Contact Us on p. 126). Checkouts must be performed as detailed and results must be recorded
and kept in the appropriate place (e.g., near the machine, and/or in a technical file). This must include a printout of the SX’s
configuration and the shape of all Safety Zones.
Additional factors and checks may be required that are dependent on the application, machine, or local regulations and laws.
A user risk assessment will determine what these additional factors and checks will be and should be incorporated with the
checkouts below. For easy reference, print out the procedures and post them near the machine/application.

• Verifying the cover to the 4-pin M12/Euro-Style Ethernet connector is in place over the connector or a cable is
securely connected
Record the checkout results and store on or near the guarded machine as required by applicable standards.
WARNING:
• There is a risk of unpredictable machine behavior at the initial start up of the machine.
• Failure to follow these instructions could result in serious injury or death.
• The Qualified Person must take precautions to ensure that no one is in or near the hazardous area
during these safety system tests.
1. Examine the guarded machine to verify that it is of a type and design compatible with the SX system. For a list of
appropriate and inappropriate applications, see Appropriate Applications on p. 10.
2. Verify the SX system is configured for the intended application and all mounting hardware is secured.
3. Verify that the minimum safety (separation) distance from the closest hazard of the guarded machine to the Safety
Zone(s) is not less than the calculated distance. See Minimum Safety (Separation) Distance for Stationary
Applications on p. 34 and Mobile Applications on p. 38.
4. Verify that:
a) Access to any dangerous parts of the guarded machine is not possible from any direction not protected by the SX
system, hard guarding, or supplemental safeguarding; and
b) It is not possible for a person to stand between or climb over/under the protected Field(s) and the dangerous parts
of the machine, or stand on top of the SX system; or
c) Supplemental safeguarding and hard guarding, as described by the appropriate safety standards, are in place
and functioning properly in any space between the Safety Zone(s) and any hazard that is large enough to allow a
person to be undetected by the SX system.
5. Verify that all reset switches are mounted outside and in full view of the guarded area, out of reach of anyone inside
the guarded area, and that means of preventing inadvertent use is in place.
6. Examine the electrical wiring connections between the Scanner OSSD outputs and the guarded machine’s control
elements to verify that the wiring meets the requirements stated in Electrical Connections on p. 47 and Electrical
Connections to the Guarded Machine on p. 48.
7. Remove all obstructions from the Safety Zone(s). Apply power to the SX system. Verify that power to the guarded
machine is off.
•If the SX system is configured for Start Interlock (Manual Power-Up), LED 1 will show green, LED 5 will be
on and the display shows RESTART (Interlock 1). Perform a manual reset (close the reset switch for 0.5 to 4.5
seconds, then open the switch) to turn on the OSSD outputs.
•If the SX system is configured for Automatic Start (Automatic Reset), LED 1 will show GREEN and the
display will show GO, and the OSSD outputs turn on (after the restart delay time).
8. Observe the Diagnostic Display on remote scanner displays also (if configured).
•Lockout—Lockout information listed on the display.
•Safety Zone interrupted—Red STOP shown on display with direction of interruption also red.
•Safety Zone Clear and OSSDs on—Green GO shown on the display.
•Start/Restart Interlock (OSSDs off, waiting for reset)—Restart in a circle with Interlock below it shown on the
display.
9. An interrupted Safety Zone (SZ) condition indicates that one or more objects are being detected within the active
protected Zone. To correct this situation, identify the interruption using the software's Monitoring mode or by
observing the area covered by the Safety Zone, and then remove all objects or realign the SX system. If the system is
in a Start/Restart Interlock (waiting for Reset) condition, perform a manual reset.
10. After the display shows the green GO, perform the trip test ( Perform a Trip Test on p. 65) on each of the configured
Safety Zones on all scanners to verify proper system operation and to detect possible unmonitored areas. Verify that
if the Safety Zone boundary is identified (for example, marked on the floor), that it matches the corresponding Safety
Zone. Do not continue until the SX system passes the trip test. Do not expose any individual to any hazard during the
following checks.

WARNING:
• Before applying power to the machine, verify the area is clear.
• Failure to follow these instructions could result in serious injury or death.
• Verify the guarded area is clear of personnel and unwanted materials (such as tools)
before applying power to the guarded machine.
WARNING:
• If the trip test fails, do not use the system.
• Failure to follow these instructions could result in serious injury or death.
• If the SX system does not respond properly to the trip test, do not attempt to use the
system. If this occurs, the SX system cannot be relied on to stop dangerous machine
motion when a person or object enters the Safety Zone.
11. Apply power to the guarded machine and verify that the machine does not start up. Interrupt the Safety Zone with the
appropriate test piece (whose size matches the configured resolution) and verify that it is not possible for the guarded
machine to be put into motion while the Safety Zone is interrupted. Repeat for each configured Safety Zone.
12. Initiate the machine cycle or motion of the guarded machine or mobile vehicle. While it is moving, use the appropriate
test piece to interrupt the Safety Zone. Do not attempt to insert the test piece into the dangerous parts of the machine
or directly in the path of the moving vehicle. Upon interrupting the Safety Zone (at any point), verify that:
a) For stationary applications: The dangerous parts of the machine come to a stop with no apparent delay.
Remove the test piece from the Safety Zone; verify that the machine does not automatically restart, and that the
initiation device(s) must be engaged to restart the machine.
b) For mobile applications: The vehicle stops within the identified/predetermined distance. Remove the test piece
from the Safety Zone; verify that the vehicle does not unintentionally restart, and, if required, that the initiation
device(s) must be engaged to restart the mobile vehicle. This must be accomplished at numerous points along the
entire route (for example, testing each of the Field Pairs in the configuration).
13. Remove electrical power to the SX system. Verify that all OSSD outputs immediately turn off and the machine is not
capable of starting until power is re-applied to the SX system.
14. Test the machine stopping response time, using an instrument designed for that purpose, to verify that it is the same
or less than the overall system response time specified by the machine manufacturer.
15. If the Ethernet cable is removed, ensure the cover is tightly in place.
Do not continue operation until the entire checkout procedure is complete and all problems are corrected.
WARNING:
• Do not use the machine until the system is working properly.
• Attempts to use the guarded machine if these checks cannot be verified could result in serious
injury or death.
• If all these checks cannot be verified, do not attempt to use or operate the machine until the defect
or problem has been corrected.

9 Troubleshooting
9.1 Initial Troubleshooting Steps
The SX uses three diagnostics levels to quickly resolve errors. Follow these steps to resolve an error.
WARNING:
• Remove power from the machinery before servicing it.
• Servicing the SX while the hazardous machinery is operational could result in serious injury or
death.
• The machinery to which the Scanner is connected must not be operating at any time during major
service or maintenance. This may require lockout/tagout procedures (refer to OSHA1910.147,
ANSI Z244-1, or the appropriate standard for controlling hazardous energy).
1. Determine the SX’s status, signaled via LEDs and the Diagnostic Display.
2. Remove the errors with the specified measures listed in the diagnostic key.
9.2 Troubleshooting Lockout Conditions
WARNING:
• Power failures and Lockout conditions indicate a problem
• Attempts to continue to operate machinery by bypassing the SX or other safeguards is dangerous
and could result in serious injury or death.
• Power failures and Lockout conditions indicate a problem and must be investigated immediately
by a Qualified Person.
A Lockout condition causes all the SX OSSD outputs to turn or remain off, sending a stop signal to the guarded machine.
Diagnostic error codes are available to assist in the identification of the cause(s) of lockouts.
The SX provides easy methods for determining operating problems. The Lockout condition is indicated by the display
showing a red box with a symbol and error code listed in it.
To recover from a Lockout condition:
1. Correct all errors.
2. Perform the reset routine or cycle power to the SX (power the SX down, wait five to 10 seconds, then power it up).

9.6 Check for Sources of Electrical and Optical Noise
The SX is designed and manufactured to be highly resistant to electrical and optical noise and to operate reliably in industrial
settings. However, serious electrical and/or optical noise may cause a random OFF state of the OSSDs. In very extreme
electrical noise cases, a Lockout is possible.
Do not directly ground the SX housing. Make only those connections as described in this document.
All SX wiring is low voltage. Running these wires alongside power wires, motor/servo wires, or other high-voltage wiring can
inject noise into the SX. It is good wiring practice (and may be required by code) to isolate SX wires from high-voltage wires.
The Banner model BT-1 Beam Tracker (see Banner catalog or website) is a very good tool for detecting electrical noise. It
can be used to detect electrical transient spikes and surges.
If random nuisance noise problems occur:
1. Check for optical interference from adjacent safety laser scanners or other photoelectric sensors.
a) Turn off the Scanner.
b) Use a Banner BT-1 Beam Tracker to check for light at the SX front screen (window) by press the RCV button on
the BT-1 and moving across the full length of the window with the BT-1 lenses facing away from the SX.
c) If the BT-1’s indicator lights up, check for light from other sources (e.g., other safety laser scanners) by tracking
down the emitted light using the BT-1.
SX Safety Laser Scanner
112 www.bannerengineering.com - Tel: + 1 888 373 6767
2. Check for sources of electrical noise.
a) Turn off the Scanner.
b) Cover the lens of the BT-1 with electrical tape to block optical light from getting into the receiver lens.
c) Press the RCV button on the BT-1 and position the Beam Tracker on the wires going to the Scanner or any other
nearby wires.
d) To reduce or eliminate noise caused by the switching of inductive loads, install proper transient suppression
across the load.
3. Try using a separate filtered power supply and/or a grounded shielded cable to connect the scanner to the cabinet to
eliminate external causes of the nuisance noise.
