Cautions for use
1. Non-voltage input type
For both panel mounting and PC
board mounting types
1) Never apply voltage to the non-voltage
input type. This will damage the internal
elements. Also, since there is a possibility
of erroneous operation, do not connect in
parallel the inputs of a non-voltage input
type and another counter from a single
input signal.
2) Since the current flow is very small
from the count input and reset input
terminals (1 and 3 on the panel
mounting type and terminals e to t and
S to F on the PC board mounting type)
please use relays and switches with high
contact reliability.
3) When inputting with an open collector
of a transistor, use a transistor for small
signals in which ICBO is 1 µA or less and
always input with no voltage.
4) When wiring, try to keep all the input
lines to the count and reset inputs as
short as possible and avoid running them
together with high voltage and power
transmission lines or in a power conduit.
Also, malfunctions might occur if the
floating capacitance of these wires
exceeds 500 pF (10 m 32.808 ft. for
parallel wires of 2 mm2). When using 2
kHz mode, use with a wiring floating
capacitance of 120 pF (3 m 9.843 ft. for
parallel wires of 2 mm2). In particular,
when using shielded wiring, be careful of
the capacitance between wires.
PC board mounting type
1) For external power supply use
manganese dioxide or lithium batteries
(CR type: 3V).
2) Always reset after external power is
applied and confirm that the display
reads “0”.
3) Make the wiring from the battery to the
counter unit as short as absolutely
possible. Also, be careful of polarity.
4) Calculate battery life with the following
formula.
t = A/I
t: battery life [h]
I: LC2H current consumption [mA]
A: battery capacity until minimum
operation voltage is reached [mAh]
5) Hand solder to the lead terminal. Do
not dip solder. With the tip of the
soldering iron at 300°C 572°F perform
soldering within 3 seconds (for 30 to 60
W soldering iron).
2. Voltage input type
1) Be aware that applying more than 30 V
DC to count input terminals 1 and 2,
and reset input terminals 3 and 4 will
cause damage to the internal elements.
2) For external resetting use H level
(application of 4.5 to 30 V DC) between
reset terminals 3 and 4 of the rear
terminals. In this case, connect + to
terminal 3 and – to terminal 4. This is
the valid polarity; therefore, the counter
will not work if reversed.
3) When wiring, try to keep all the input
lines to the count and reset inputs as
short as possible and avoid running them
together with high voltage and power
transmission lines or in a power conduit.
Also, malfunctions might occur if the
floating capacitance of these wires
exceeds 500 pF (10 m 32.808 ft. for
parallel wires of 2 mm2).
3. Free voltage input type
1) Use count input terminals 1 and 2 for
free voltage input and reset terminals 3
and 4 for non-voltage input.
2) Be aware that the application of
voltage that exceeds the voltage range of
the H level to the count input terminal,
and the application of voltage to the reset
input terminal, can cause damage to the
internal elements.
3) Since the current flow is very small
from reset input terminal 3, please use
relays and switches with high contact
reliability.
4) When inputting a reset with an open
collector of a transistor, use a transistor
for small signals in which ICBO is 1 µA or
less and always input with no voltage.
5) To reset externally, short reset input
terminals 3 and 4 on the rear.
6) Input uses a high impedance circuit;
therefore, erroneous operation may occur
if the influence of induction voltage is
present. If you plan to use wiring for the
input signal that is 10 m or longer (wire
capacitance 120 pF/m at normal
temperature), we recommend the use of
a CR filter or the connection of a bleeder
resistor.
4. How to reset multiple panel
mounting type counters all at once
(input is the same for count)
Non-voltage input type
Notes) 1. Use the following as a guide for choosing
transistors used for input (Tr).
Leakage current < 1 µA
2. Use as small a diode (D) as possible in the
forward voltage so that the voltage between
terminals 3 and 4 during reset input meets
the standard value (0.5 V).
( At IF = 20 µA, forward voltage 0.1 and
higher.)
Voltage input type
Note) Make sure that H (reset ON) level is at least 4.5
V.
5. Backlight luminance
To prevent varying luminance among
backlights when using multiple Backlight
types, please use the same backlight
power supply.
6. Environment for use
1) Ambient conditions
• Overvoltage category II, pollution level 2
• Indoor use
• Acceptable temperature and humidity
range: –10 to +55°C, 35 to 85%RH (with
no condensation at 20°C)
• Under 2000 m elevation
2) Use the main unit in a location that
matches the following conditions.
There is minimal dust and no corrosive
gas.
There is no combustible or explosive
gas.
There is no mechanical vibration or
impacts.
There is no exposure to direct sunlight.
• Located away from large-volume
electromagnetic switches and power
lines with large electrical currents.
3) Connect a breaker that conforms to
EN60947-1 or EN60947-3 to the voltage
input section.
4) Applied voltage should be protected
with an overcurrent protection device
(example: T 1A, 250 V AC time lag fuse)
that conforms to the EN/IEC standards.

1. It is possible to change the preset
value even during counting. However,
be aware of the following points.
1) If the preset value is changed to less
than the count value with counting set to
the addition direction, counting will
continue until it reaches full scale, returns
to zero, and then reaches the new preset
value. If the preset value is changed to a
value above the count value, counting will
continue until the count value reaches the
new preset value.
2) Suppose that the counter is preset to
count down. Whether a preset count
down value is smaller or larger than the
count value, the counter counts down to
“0 (zero)”.
2. If the preset value is changed to “0”,
the counter will not complete count-
up. It starts counting up when the
counting value comes to “0 (zero)”
again.
1) Addition (up-count) input when
counting is set to the addition direction,
counting will continue until full scale is
reached, return to zero, and then
complete count-up.
2) Subtraction (down-count) input when
counting is set to the subtraction direction,
counting will continue until full scale
“–9999999” is reached, and then the
display will change to “ ”.

Cautions for use
1. Input and output connection
1) Input connection
(1) Contact input
Use highly reliable metal plated contacts.
Since the contact’s bounce time leads
directly to error in the count value, use
contacts with as short a bounce time as
possible. In general, select input to have
a maximum counting speed of 30 Hz.
(2) Non-contact input (Transistor input)
Connect with an open collector. Use
transistors whose characteristics satisfy
the criteria given below.
VCEO = Min. 20 V
IC = Min. 20 mA
ICBO = Max. 6 µA
Also, use transistors with a residual
voltage of less than 2 V when the
transistor is on.
* The short-circuit impedance should be less
than 1 k.
(When the impedance is 0 , the current
coming from the count input terminal is
approximately 5 mA and from the reset
input terminal is approximately 1.5 mA.)
Also, the open-circuit impedance should
be more than 100 k.
(3) Input wiring
When wiring, use shielded wires or
metallic wire tubes, and keep the wire
lengths as short as possible.
2) Output connection
Since the transistor output of counter is
insulated from the internal circuitry by a
photo-coupler, it can be used as an NPN
output or PNP (equal value) output.

2. Self-diagnosis function
If a malfunction occurs, one of the following displays will appear.
* Includes the possibility that the EEP-ROM’s life has expired.
3. Terminal connection
1) When wiring the terminals, refer to the terminal layout and
wiring diagrams and be sure to perform the wiring properly
without errors.
An external power supply is required in order to run the main
unit.
Power should be applied between
terminals (1) and (2). Terminal (1) acts
as the positive connection and terminal
(2) as the negative.
2) After turning the counter off, make sure that any resulting
induced voltage or residual voltage is not applied to power
supply terminals (1) through (2). (If the power supply wire is
wired parallel to the high voltage wire or power wire, an induced
voltage may be generated at the power supply terminal.)
3) Have the power supply voltage pass through a switch or relay
so that it is applied at one time.

COUNTE R-RE LATE D TE RMINOLOGY
COUNTER-RELATED TERMINOLOGY
TYPES OF COUNTERS
1. Electro Preset Counter
The counter is equipped with semicon-
ductor counting circuitry. When the
counter counts up to a preset number, its
output circuit sends a signal.
2. Electro Magnetic Counter
A magnet is magnetized and demagne-
tized to drive the dial and count up num-
bers.
RATING
1. Rated Operating Voltage
The voltage is applied to start the
counter.
COUNTINGS
1. Pulse
This is a voltage or current signal sent at
intermittent time intervals.
2. Count
Pulses are used to count up and down.
3. Miss-count
This happens if the number of pulses
does not correspond to the number of
counts.
4. Hertz
This unit of counting speed is used to
give the number of counts per one
second.
5. Make Ratio
This is the ratio of ON time (Ta) to OFF
time (Tb).
6. Maximum Counting Speed
Suppose that the counter is operated
with an input pulse of a make ratio of 1.
The highest counting speed is the peak
of a range in which the output circuit can
send signals without mis-counting. The
speed is expressed in units of Hz (cps:
counts per a second).
7. Over Count
Counting continues beyond a preset
number.
8. Recount
When counting is up, the counter display
resets to zero and counting restarts.
9. Down Count
Numbers are counted down one by one
from a preset number.
10. Up Count
Numbers are counted up one by one
from zero.
11. Up/Down Count
Numbers are counted up or down
depending on input
conditions.
12. Rejection (gate) Input
This signal is used to keep the counter
from counting.
OUTPUTS
1. Count Up
When a preset number is reached, the
output circuit sends a signal.
2. Retained Output
The output is held until a reset signal is
sent.
3. One Shot Output
This output has a specified width of time.
RESETTINGS
1. Reset
The counting process, display and output
sections are all brought back to the initial
status.
2. Power off Reset
The operating voltage is turned off to
reset the counter.
3. Manual Reset
The counter is manually reset.
4. Remote Reset
A signal is sent from a remote point to
the reset terminal so as to reset the
counter.
5. Automatic Reset
When counting is up, internal circuitry is
activated to automatically reset the
counter.
6. Reset Signal Width
This is the time during which the power
is off so as to reset the counter or during
which an external (manual) reset signal
is sent.
7. Reset time
This is the time from the moment a reset
signal is sent to the instant the counter is
ready to start counting again.
OTHERS
1. Function of Memorizing Condition
Counting data up until the operating
voltage is turned off can be stored in
memory. When the power is reactivated,
the data can be reproduced.
2. Anti-surge
The strength against power voltage
surge is determined by applying a single-
pole full-wave voltage (several hundred
to several thousand volt wave for ±(1.2 ×
50) µs) acrosss the control power
terminals.
Surge waveform
[Single-pole full-wave voltage for ±(1.2 ×

3. Noise Immunity
This is the strength against external
noise. Relay noise tests, noise simulator
tests, etc. are conducted.

PRECAUTIONS IN USING THE COUNTER «Wm <% m Fm é% ‘m if“? ‘ o I fit?
PRECAUTIONS IN USING THE COUNTER
Cautions for circuits
1. Protective circuit for counter contact
In the circuit that switches an inductive load, a contact failure may occur at a contact point due to surge or inrush current resulting
from that switching. Therefore, it is recommended that the following protective circuit be used to protect the contact point.
2. Type of Load and Inrush Current
The type of load and its inrush current
characteristics, together with the switch-
ing frequency, are important factors
which cause contact welding.
Particularly for loads with inrush cur-
rents, measure the steady state current
and inrush current and use a relay or
magnet switch which provides an ample
margin of safety. The table below shows
the relationship between typical loads
and their inrush currents.
various kinds of input signals, therefore,
use a power transformer in which the pri-
mary side is separated from the
ungrounded secondary side as shown in
Fig. A, for the power supply for a sensor
and other input devices so that short-cir-
cuiting can be prevented.
4. Long Continuous Current Flow
Avoid keeping the counter on for a long
period of time (over one month).
Otherwise heat is generated and accu-
mulated inside the counter, which may
deteriorate its electronic parts. If the
counter must be kept on for a long period
of time, a relay is added. See the circuit
diagram below.
When you want large load and long life
of the counter, do not control the load
direct with a counter. When the counter
is designed to use a relay or a magnet
switch, you can acquire the longer life of
the counter.
3. Connection of input
(Except for LC4H-S/AC type)
The LC4H series use power supply with-
out a transformer (power and input termi-
nals are not insulated). In connecting

Application
Features/Others
Device Selection
AC Available
If the load is a relay or solenoid, the release time lengthens.
Effective when connected to both contacts if the power supply voltage is
24 or 48 V and the voltage across the load is 100 to 200 V.
If the load is a timer, leakage current
flows through the CR circuit causing
faulty operation.
Note: If used with AC voltage, be sure
the impedance of the load is sufficiently
smaller than that of the CR circuit.
As a guide in selecting r and c,
c: 0.5 to 1 µF per 1 A contact current
r: 0.5 to 1 per 1 V contact voltage
Values vary depending on the properties of the load and variations in counter charac-
teristics.
Capacitor c acts to suppress the discharge the moment the contacts open. Resistor r
acts to limit the current when the power is turned on the next time. Test to confirm.
Use a capacitor with a breakdown voltage of 200 to 300 V. Use AC type capacitors
(non-polarized) for AC circuits.
The diode connected in parallel caus-
es the energy stored in the coil to
flow to the coil in the form of current
and dissipates it as joule heat at the
resistance component of the induc-
tive load.
This circuit further delays the release
time compared to the CR circuit.
(2 to 5 times the release time listed in
the catalog)
Use a diode with a reverse break-
down voltage at least 10 times the
circuit voltage and a forward cur-
rent at least as large as the load
current.
In electronic circuits where the cir-
cuit voltages reverse breakdown
voltage of about 2 to 3 times the
power supply voltage.
Using the rated voltage characteris-
tics of the varistor, this circuit pre-
vents excessively high voltages
from being applied across the con-
tacts. This circuit also slightly
delays the release time.

Diode circuit Varistor circuit
Do not use a single coil transformer (e.g.,
Sly-Duck). Otherwise, the internal circuit
of the counter will be short-circuited as
shown in Fig. B resulting in breakdown.

5. Leakage current
1) For connecting operating voltage to
the counter, a circuit should be used,
which will prevent the flow of leakage
current. For example, a circuit for con-
tact protection as shown in Fig A. will
permit leakage current flow through R
and C, causing erroneous operation of
the counter. Instead, the circuit shown in
Fig. B should be used.
2) If the counter
is directly
switched with a
non-contact ele-
ment, leak cur-
rent may flow
into the counter
and cause it to
malfunction.
Cautions for use
(common for all models)
1. Terminal connections
Correctly connect the pins while seeing
the terminal layout/wiring diagram. In
particular, the DC type, which has polari-
ties, does not operate with the polarities
connected reverse. Any incorrect con-
nection can cause abnormal heating or
ignition.
2. Connection to operating voltage
1)Apply the entire supply voltage through
a switch, relay or other contact.
2) The operating voltage for the DC type
must be at the specified ripple percent-
age or less. The average voltage must
fall within the allowable operating voltage
range.
5. Superimposed surge of power
supply
For the superimposed surge of power
supply, the standard waveform (±1.2 ×
50µs or ±1 ×40µs) is taken as the stan-
dard value for surge-proof voltage. (The
positive and negative voltages are
applied each three or five times between
the power pins.)
For the standard values for the LC4H
type counters, see the respective items
in "Cautions for use."
• Single-pole, full-wave voltage for surge
waveform [±(1.2 ×50) µs]
If external surge occurs exceeding the
specified value, the internal circuit may
break down. In this case, use a surge
absorption element. The typical surge
absorption elements include a varistor, a
capacitor, and a diode. If a surge
absorption element is used, use an oscil-
loscope to see whether or not the foreign
surge exceeding the specified value
appears.
6. Signal input
The counter's signal input comes in two
ways. One is by opening and closing the
input terminal. The other is by applying a
specified H-level or L-level voltage to the
input terminal.
For an input sensor's residual voltage,
input impedance, input voltage level and
other signal input conditions, see the rat-
ings for each type of product.
7. Operating environment
1) For the ambient operating tempera-
ture and humidity, see the ratings for
each type of product.
2) Avoid using the counter in a location
where inflammable or corrosive gas is
generated, the counter is exposed to
much dust and other foreign matter; water
or oil is splashed on the counter; or vibra-
tions or shocks are given to the counter.
3) The counter cover (case), the knobs,
and the dials are made of polycarbonat-
ed resin. Therefore, prevent the counter
from being exposed to organic solvents
such as methyl alcohol, benzine, and
thinner, strong acid substances such as
caustic soda, and ammonia and avoid
using the counter in atmosphere contain-
ing any of those substances.
4) If the counter is used where noises
are emitted frequently, separate the input
signal elements (such as a sensor), the
wiring for the input signal line, and the
counter as far as possible from the noise
source and the high power line contain-
ing noises.
8. Checking the actual load
In order to increase the reliability in the
actual use, check the quality of the
counter in the actual usage.
9. Others
1) If the counter is used exceeding the
ratings (operating voltage and control
capacity), the contact life, or any other
specified limit, abnormal heat, smoke, or
ignition may occur.
2) The LC2H series counter, incorpo-
rates a lithium battery.
Never disassemble the lithium battery or
throw it into fire because this may affect
humans and facilities. The lithium bat-
tery must be disposed of as an incom-
bustible like other used batteries.
3) If any malfunction of the counter is
likely to affect human life and properties,
give allowance to the rated values and
performance values. In addition, take
appropriate safety measures such as a
duplex circuit from the viewpoint of prod-
uct liabilities.
3) Make sure that no induced voltage
and residual voltage are applied between
the power terminals on the counter after
the power switch is turned OFF.
(If the power line is wired in parallel with
the high-voltage and motor lines,
induced voltage may be produced
between the power pins.)
3. Control output
1) Keep the load capacity below the
counter's rated control capacity. If used
above the rating, the counter's service
life may shorten. With the transistor out-
put type counters, transistors may be
damaged.
4. Installing the counter
1) To install the counter, use the dedicat-
ed pin bracket or socket (cap). Avoid
connecting the pins on the counter by
directly soldering them.
2) In order to maintain the characteris-
tics, do not remove the counter cover
(case).

INSTALLING DIN SIZE COUNTER FWD—Iran Efiéa "III
145
Installation methods
1. Surface mount
1) For the counters of LC4H series, use
the pin type counter.
INSTALLING DIN SIZE COUNTER
5) Correctly connect the terminals while
seeing the terminal layout and wiring
diagram.
6) If the pin type is used, the rear pin-
bracket (AT8-RR) or the 8P cap (AD8-
RC) is necessary to connect the pins.
For the 11-pin type, use the 11P cap
(AT8-DP11) and avoid directly soldering
the round pins on the counter.
7) Panel cutout dimensions
The standard panel
cutout dimensions are
shown in the left fig-
ure. (Panel thickness:
1 to 5 mm .039 to .197
inch)
8) Although the
counters can be
mounted adja-
cent to each
other in this
case, it is rec-
ommended to
arrange the
mounting holes
as shown in the
figure to facili-
tate attaching
and detaching
the mounting
frame.
9) Adjacent mounting
Although the counters can be mounted
adjacent to each other, remember that
the panel surface of LC4H series counter
will lose its water-resistant effect. (Panel
thickness: 1 to 5 mm .039 to .197 inch)
A = (48 ×n – 2.5)
When lining up the counters horizontally,
set the frames in such a position so the
formed spring areas are at the top and
bottom.
When lining up
the counters
vertically, set
the frames in
such a position
as the formed
spring areas
are at the right
and left.
+0.6
+0
Pull the mounting
frame backward
while spreading out
its hooks with your
thumbs and index
fingers.
3) Caution in mounting the counter
• LC4H series
a If the LC4H series are used as the
waterproof types (IEC IP66), tighten the
reinforcing screws on the mounting
frames so that the counters, the rubber
gaskets, and the panel surfaces are
tightly contacted with each other.
(Tighten the two screws with uniform
force and make sure that there is no rat-
tling. If the screws are tightened too
excessively, the mounting frame may
come off.)
b If the counter is installed with the
panel cover and the rubber gasket
removed, the waterproofing characteris-
tic is lost.
4) Removal
Loosen the screws on the mounting
frame, spread the edge of frame and
remove it.
2) How to mount the counter
From the panel front, pass the counter
through the square hole. Fit the mount-
ing frame from the rear, and then push it
in so that the clearance between the
mounting frame and the panel surface is
minimized. In addition, lock the mount-
ing frame with a screw.
• LC4H series
5) 8-pin type should be connected with
terminal socket AT8-DF8K. 11-pin type
should be connected with terminal sock-
et AT8-DF11K.
6) DIN rail (AT8-DLA1) is also available
(1 m).
2. Flush mount
1) For the counters of LC4H series, it is
recommended to use the built-in screw
terminal type for flush mount. (Mounting
frame and rubber gasket are provided
when counter is shipped.)
2) Put the terminal socket on the board
directly or put it on the DIN rail (Fig. 1).
3) Insert the counter into the terminal
socket and fix it with clip (Fig. 2)
4) On DIN rail mounting, mount the
counter on the DIN rail tightly to get the
proper dimension (Fig. 3).

FOREIGN SPECIFICATIONS OVERVIEW
4. Shipping Standards
(1) Lloyd’s Register of Shipping
Standards from the Lloyd’s Register shipping asso-
ciation based in England. These standards are
safety standards for environmental testing of the
temperature and vibration tolerances of electrical
components used for UMS (unmanned machine
rooms in marine vessels) applications. These stan-
dards have become international standards for
control equipment in all marine vessel applications.
No particular action is taken to display the confor-
mation to these standards on the products.
1. International Standards
IEC standard International Electrotechnical Commission
By promoting international cooperation toward all
problems and related issues regarding
standardization in the electrical and electronic
technology fields, the IEC, a non-governmental
organization, was started in October, 1908, for the
purpose of realizing mutual understanding on an
international level. To this end, the IEC standard
was enacted for the purpose of promoting
international standardization.
2. North America
UL (Underwiters Laboratories Inc.)
This is a non-profit testing organization formed in
1894 by a coalition of U.S. fire insurance firms,
which tests and approves industrial products
(finished products). When electrical products are
marketed in the U.S., UL approval is mandated in
many states, by state law and city ordinances. In
order to obtain UL approval, the principal parts
contained in industrial products must also be UL-
approved parts.
UL approval is divided into two general types. One
is called “listing” (Fig. 1), and applies to industrial
products (finished products). Under this type of
approval, products must be approved
unconditionally. The other type is called
“recognition” (Fig. 2), and is a conditional approval
which applies to parts and materials.
CSA (Canadian Standards Association)
This was established in 1919 as a non-profit, non-
governmental organization aimed at promoting
standards. It sets standards for industrial products,
parts, and materials, and has the authority to judge
electrical products to determine whether they
conform to those standards. The CSA is the ultimate
authority in the eyes of both the government and the
people in terms of credibility and respect. Almost all
states and provinces in Canada require CSA
approval by law, in order to sell electrical products.
As a result, electrical products exported from Japan
to Canada are not approved under Canadian laws
unless they have received CSA approval and
display the CSA mark. Approval is called
“certification”, and products and parts which have
been approved are called “certified equipment”, and
display the mark shown in Fig. 3. The mark shown
in Fig. 4 is called the “Component Acceptance”
mark, and indicates conditional approval which is
applicable to parts. The C-UL mark shown in Fig. 5
(finished products) and Fig. 6 (parts) indicates that
the product has been tested and approved in UL
laboratories, based on UL and CSA standards,
through mutual approval activities.
3. Europe
EN standard European Standards/Norme Europeennee
(France)/Europaishe Norm (Germany)
Abbreviation for European Standards. A unified
standard enacted by CEN/CENELEC (European
Standards Committee/European Electrical
Standards Committee). EU and EFTA member
nations employ the content of the EN standards into
their own national standards and are obligated to
abolish those national standards that do not agree
with the EN standards.
(1) Germany VDE (Verband Deutscher Elektrotechniker)
The VDE laboratory was established mainly by the
German Electric Technology Alliance, which was
formed in 1893. It carries out safety experiments
and passes approval for electrical devices and
parts. Although VDE certification is not enforced
under German law, punishment is severe should
electrical shock or fire occur; therefore, it is, in fact,
like an enforcement.
TÜV (Technischer Überwachungs-Verein)
TÜV is a civilian, non-profit, independent
organization that has its roots in the German Boiler
Surveillance Association, which was started in 1875
for the purpose of preventing boiler accidents. A
major characteristic of TÜV is that it exists as a
combination of 14 independent organizations (TÜV
Rheinland, TÜV Bayern, etc.) throughout Germany.
TÜV carries out inspection on a wide variety of
industrial devices and equipment, and has been
entrusted to handle electrical products, as well, by
the government. TÜV inspection and certification is
based mainly on the VDE standard.
TÜV certification can be obtained from any of the 14
TÜVs throughout Germany and has the same
effectiveness as obtaining VDE certification.

5. Pilot Duty One of the specifications in the “UL508
Industrial Control Equipment” regulations at
UL (Underwriters Laboratories Inc.), has to
do with the grade of contact control capacity
by NEMA (National Electrical Manufacturers
Association) standards. By obtaining both UL
and CSA approval for this grade, the product
becomes authorized publicly.

C E MARKINGS OVE RVIEW
CE MARKINGS OVERVIEW
Counter, Hour Meter conforming to
EN/IEC standards
The Timer, Counter, Hour Meter shown below conform to both EN and IEC standards,
and may display the CE markings.
CE markings and EC
directives
The world’s largest single market, the
European Community (EC) was born on
1 January 1993 (changing its name to
EU in November 1993. It is now always
expressed as EU, apart from EC direc-
tives.) EU member country products
have always had their quality and safety
guaranteed according to the individual
standards of each member country.
However, the standards of each country
being different prevented the free flow of
goods within the EU. For this reason, in
order to eliminate non-tariff barriers due
to these standards, and to maximize the
merits of EU unification, the EC direc-
tives were issued concomitant to the
birth of the EU.
The EN standards were established as
universal EU standards in order to facili-
tate EU directives. These standards
were merged with the international IEC
standards and henceforth reflect the
standards in all countries. Also, the CE
markings show that products conform to
EC directives, and guarantee the free
flow of products within the EC.
Appropriate
EC directives for control
equipment products
The main EC directives that are to do
with machinery and electrical equipment
are the machinery directive, the EMC
directive, the low voltage directive, and
the telecom directive. Although these
directives have already been issued, the
date of their enactment is different for
each one. The machinery directive was 1
January 1995. The EMC directive was 1
January 1996, and the low voltage direc-
tive was enacted from 1 January 1997.
The telecom directive was established by
the separate CTR (Common Technology
References.)
What are EN standards?
An abbreviation of Norme Europeenne
(in French), and called European
Standards in English. Approval is by vote
among the CEN/CENELEC member
countries, and is a unified standards
limited to EU member countries, but the
contents conform to the international
ISO/IEC standards.
