5 Safety regulations and installation notes
General
Observe the safety regulations of electrical engineering
and industrial safety and liability associations.
Disregarding these safety regulations may result in death,
serious personal injury or damage to equipment.
Power supply units for power supply
Provide external protection for the input area (A1/A2).
Make sure that the power supply unit is able to supply
four times the nominal current of the external fuse, to
ensure that it trips in the event of an error.
Startup, mounting, and modifications
Startup, mounting, modifications, and upgrades may only be
carried out by an electrically skilled person.
Before working on the device, disconnect the power.
Carry out wiring according to the application. Refer to
the “Application examples” section for this.
Reliable operation is only ensured if the device is installed in
housing protected from dust and humidity.
Install the device in housing protected from dust and
humidity (min.IP54).
In operation
During operation, parts of electrical switching devices carry
hazardous voltages.
Protective covers must not be removed when operating
electrical switching devices.
For emergency stop applications, automatic startup of the
machine can pose serious risks for the user.
The machine must be prevented from restarting
automatically by a higher-level controller.
With the manual, monitored reset device, a machine start
may not be triggered in accordance with ENISO13849-1.
Inductive loads can lead to welded relay contacts.
Connect a suitable and effective protective circuit to
inductive loads.
Implement the protective circuit parallel to the load and
not parallel to the switch contact.
Magnetic fields can influence the device. The magnetic field
strength of the environment must not exceed 30A/m.
Do not use the device in the vicinity of strong magnetic
fields (e.g.,caused by transformers or magnetic iron).
Noise emission may occur when operating relay modules.
Wireless reception may be disrupted in residential areas.
The device is a Class A product.
Observe the requirements for noise emission for
electrical and electronic equipment (EN61000-6-4).
Implement appropriate precautions against noise
emission.
Faulty devices
The devices may be damaged following an error. Correct
operation can no longer be ensured.
In the event of an error, replace the device.
Only the manufacturer or their authorized representative
may perform the following activities. Otherwise the warranty
is invalidated.
Repairs to the device
Opening the housing
Taking out of service and disposal
Dispose of the device in accordance with environmental
regulations.
Make sure that the device can never be reused.
WARNING: Death, serious personal injury or damage to equipment
Depending on the application, incorrect handling of the device may pose serious risks for the user or cause
damage to equipment.
Observe all the safety notes and warning instructions provided in this chapter and elsewhere in this
document.

6 Function description
6.1 Single-channel sensor circuit
The sensor circuit is not designed with redundancy.
The safety relay does not detect short and cross-circuits in
the sensor circuit.
6.2 Two-channel sensor circuit
The sensor circuit is designed with redundancy.
With the corresponding wiring, the safety relay detects short
and cross-circuits in the sensor circuit.
6.3 Automatic start
The device starts automatically after the sensor circuit has
been closed.
6.4 Manual, monitored start
When the sensor circuit is closed, the device starts once the
start circuit has been closed and opened again by pressing
and releasing the reset button.
A connected reset button is monitored.
6.5 Safe shutdown
When the sensor circuit opens, the enabling current paths
open without delay.
When the enabling current paths are open, the device is in
the safe state.
The signaling current path closes.

Basic insulation
(rated surge voltage of 4kV)
A mixture of SELV and PELV is strictly
prohibited. Only switch 230VAC at one of the
enable contacts if the adjacent contact carries
the same potential.
Safe isolation/reinforced insulation
(rated surge voltage of 6kV)
Reinforced insulation (e.g.,thanks to greater
air clearances and creepage distances
between conductive paths) is designed for
one overvoltage category higher than basic
insulation. This means that SELV circuits of
U25VAC or U60VDC and circuits with
higher voltages can be mixed.

15 Calculating the power dissipation
Input power dissipation
PInput=2,7 W (with DC)
PInput=2,9 W (with AC)
Contact power dissipation
With the same load currents:
PContact=nIL²200m
With different load currents:
PContact=(IL1²+IL2²+...+ILn²)200m
Total power dissipation
PTotal=PInput+PContact
therefore
PTotal=PInput+nIL²200m
or
PTotal=PInput+(IL1²+IL2²+...+ILn²)200m

16 Diagnostics
The following section describes the LED indicators for
general states and error messages as well as possible
causes and remedies.
Function test/proof test
To verify the device function, proceed as follows:
Demand the safety function by actuating the
corresponding safety equipment.
Check whether the safety function was executed
correctly by switching the device on again.
If the device does not switch on again, the proof test failed.
16.1 General states
WARNING: Loss of functional safety due
to malfunction.
If the proof test contains errors, the device no
longer functions correctly.
Replace the device.

18.1 Using PSR devices at altitudes greater than
2000mabovesea level
Using the device at altitudes greater
than2000mabovesea level up to max. 4500mabove
sea level is possible under the following conditions:
1. Limit the rated control circuit supply voltage (US) in
accordance with the table below. Observe the technical
data for the device.
2. Limit the maximum switching voltage in accordance
with the table below. Observe the technical data for the
device.
3. Reduce the maximum ambient temperature for
operation by the corresponding factor in accordance
with the table below.
4. If derating is specified, offset all the points of the
derating curve by the corresponding factor in
accordance with the table below.
