• Changing the set value
1. It is possible to change the set
value with the up and down keys (4-
digit type only) even during counting.
However, be aware of the following
points.
1) If the set value is changed to less than
the count value with counting set to the
addition direction, counting will continue
until it reaches full scale (9999 with the
4-digit type and 999999 with the 6-digit
type), returns to zero, and then reaches
the new set value. If the set value is
changed to a value above the count
value, counting will continue until the
count value reaches the new set 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 set value is changed to “0,”
the unit will not complete count-up. It
starts counting up when the counting
value comes to “0 (Zero)” again.
1) Up-count (addition) input when count-
ing is set to the addition direction, count-
ing will continue until full scale is reached
(9999 with the 4-digit type and 999999
with the 6-digit type), return to zero, and
then complete count-up.
2) Down-count (subtraction) input when
counting is set to the subtraction direc-
tion, counting will continue until full scale
is reached (-999 with the 4-digit type and
-99999 with the 6-digit type), and then
the display will change to with
the 4-digit type and with the
6-digit type. The counting value does not
become “0” and so the counter does not
count up.
3) For directive, independent, and phase
input, when the counting value increases
or decreases from the value "0" and then
returns back to the value "0," count-up is
completed.

Operation *Minimum input signal width 30 Hz: 16.7 ms; 5 kHz: 0.1 ms
IN1 or IN2 works as an input block
(gate) for the other input.
• Example where IN1 is the count counting and IN2 is the input block (gate).
• Example where IN2 is the counting input and IN1 is the input block (gate).
* “A” must be more than the minimum input signal width.
* “A” must be more than the minimum input signal width.
* “B” must be more than the minimum input signal width.
* IN1 and IN2 are completely independent, so there is no restriction on signal
timing.
IN1 is the counting input and IN2 is the
addition or subtraction directive input.
IN2 adds at L level and subtracts at H
level.
IN1 is addition input and IN2 is subtrac-
tion input.
Addition when the IN1 phase advances
beyond IN2, and subtraction when the
IN2 phase advances beyond IN1.

Changing the set value
CAUTIONS FOR USE
For more information regarding the cautions for use of LC4H series counter, refer to page 140 “PRECAUTIONS IN USING THE
LC4H SERIES”.
1. It is possible to change the set
value with the up and down keys (4-
digit type only) even during counting.
However, be aware of the following
points.
1) If the set value is changed to less than
the count value with counting set to the
addition direction, counting will continue
until it reaches full scale (9999 with the
4-digit type and 999999 with the 6-digit
type), returns to zero, and then reaches
the new set value. If the set value is
changed to a value above the count
value, counting will continue until the
count value reaches the new set value.
2) Suppose that thew 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 set value is changed to “0,”
the unit will not complete count-up. It
starts counting up when the counting
value comes to “0 (zero)” again.
1) Up-count (addition) input
When counting is set to the addition
direction, counting will continue until full
scale is reached (9999 with the 4-digit
type and 999999 with the 6-digit type),
return to zero, and then complete count-
up.
2) Down-count (subtraction) input
When counting is set to the subtraction
direction, counting will continue until full
scale is reached (-999 with the 4-digit
type and -99999 with the 6-digit type),
and then the display will change to
with the 4-digit type and
with the 6-digit type.
The counting value does not become “0
(zero)” and so the counter does not
count up.
3) Directive, independent, and phase
inputs
The counting value is counted up or
down to any number other than “0” once.
When it comes to “0 (zero)” again, the
counter starts counting up.
EThe decimal point is set using the [UP] and [DOWN] keys to specify the 2nd, 3rd, and 4th digits (this applies only to 4-digit

• Example where IN2 is the counting input and IN1 is the input block (gate).
* “A” must be more than the minimum input signal width.
* “A” must be more than the minimum input signal width.
* “B” must be more than the minimum input signal width.
* IN1 and IN2 are completely independent, so there is no restriction on signal
timing.
IN1 is the counting input and IN2 is the
addition or subtraction directive input.
IN2 adds at L level and subtracts at H
level.
IN1 is addition input and IN2 is subtrac-
tion input.
Addition when the IN1 phase advances
beyond IN2, and subtraction when the
IN2 phase advances beyond IN1.

What is the prescale function?
The prescale function converts the count into an actual
value (amount) and displays it.
Example
For a device that outputs 500 pulses when 1 m has been fed:
1. Set decimal position to the last 3rd place.
2. Set the prescale value to 0.002 (1/500).

• Checking the input mode
Hold down the SET/LOCK key and press the UP key
for the second digit. The input mode is displayed for
about 2 seconds and then the display goes back to
normal. (During these 2 seconds, all operations
other than the display are being performed.)
• Locking the keys
Hold down the SET/LOCK key and press the UP key
for the sixth digit. The keys will lock. This means that
the UP and RESET keys do not respond to touch. To
unlock the keys,hold down the SET/LOCK key and
press the UP key for the sixth digit again.
* The input mode, maximum counting speed and minimum
reset signal width cannot be preset independently for Setting
1 and Setting 2.
• Selecting the Setting 1 or Setting 2 dis-
play
Press the SET/LOCK key and the display changes
between Setting 1 and Setting 2. (This operation
does not affect overall operation.)
• Changing the setting
1. While the counter is working, the UP key can
be used to change the setting. Keep the follow-
ing points in mind, however.
1) Suppose that a preset count-up value is smaller
than the displayed count value. The counter counts
up to the full scale mark (999999), goes back to "0",
and counts up again to the preset number. When the
preset count-up value is larger than the displayed
count value, the counter counts up to the 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".
2. When the preset value is "0", the counter does
not start in the count-up mode. It starts counting
up when the count value comes to "0" again.
1) Up-count input
The counter counts up to the full scale mark
(999999), goes back to "0" and starts counting up
again.
2) Down-count input
The counter counts down to the full scale mark
(–99999) and the display reads . The
count value does not become "0" and so the counter
does not count up.
3) Direction input, individual input, and phase input
The preset value is counted up or down to any num-
ber other than "0" once. When it comes to "0" again,
the counter starts counting up.
(1) Hold down the SET/LOCK key and press the UP key for the first digit. The setting mode is accessed.
(2) Now release the SET/LOCK key.
(3) Press the UP key for the first digit and the input position changes counterclockwise.
(4) Press the RESET key and the input mode being displayed is set. The display then goes back to normal.

ed when the count value is greater than
or equal to the preset value 1, regardless
of the input mode.)
(2) In control output 2, when the count
value is equal to 0 in the count-down
input mode, it is counted. In the other
modes, when the count value is equal to
the preset value 2, it is counted.
(However, if the output mode of the pre-
set value 2 is HOLD-D, it is counted
when the count value is greater than or
equal to the preset value 2, regardless of
the input mode.)
(3) It is not counted even when the
counting conditions are satisfied right
after resetting. It can be counted from
when the count value changes.

Precautions during usage
1. Terminal wiring
1) When wiring the terminals, refer to the
terminal layout and wiring diagrams and
be sure to perform the wiring properly
without errors.
2) When using the instrument with an
flush mounting, the screw-down terminal
type is recommended. For the pin type,
use either the rear terminal block
(AT78041) or the 8P cap (AD8-RC) for
the 8-pin type, and the rear terminal
block (AT78051) or the 11P cap (AT8-
DP11) for the 11-pin type. Avoid solder-
ing directly to the round pins on the unit.
When using the instrument with a front
panel installation, use the DIN rail termi-
nal block (AT8-DF8K) for the 8-pin type
and the DIN rail terminal block (AT8-
DF11K) for the 11-pin type.
3) After turning the counter off, make
sure that any resulting induced voltage
or residual voltage is not applied to
power supply terminals Wthrough U(8-
pin type), Wthrough P(11-pin type) or
and (screw terminal type). (If the
power supply wire is wired parallel to the
high voltage wire or power wire, an
induced voltage may be generated
between the power supply terminals.)
4) Have the power supply voltage pass
through a switch or relay so that it is
applied at one time. If the power supply
is applied gradually, the counting may
malfunction regardless of the settings,
the power supply reset may not function,
or other such unpredictable occurrence
may result.
2. Input connections (except LC4H-
S/AC type)
The power circuit has no transformer
without a transformer (power and input
terminals are not insulated). When an
input signal is fed to two or more coun-
ters at once, do not arrange the power
circuit in an independent way.
If the counter is powered on and off inde-
pendently as shown in Fig. A, the coun-
ter's internal circuitry may get dam-
aged.Be careful never to allow such cir-
cuitry. (Figs. A, B and C show the circuit-
ry for the 11-pin type.)
21
If independent power circuitry must be
used, keep the input contacts or transis-
tors separate from each other, as shown
in Fig. B.
When power circuitry is not independent,
one input signal can be fed to two or
more counters at once, as shown in Fig.
C.
3. Input and output
1) Signal input type
(1) Contact point input
Use highly reliable metal plated contacts.
Since the contact point’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 1
and Input 2 to have a maximum counting
speed of 30 Hz and to be reset with a
minimum input signal width of 20 ms.
(2) Non-contact point input
Connect with an open collector. Use
transistors whose characteristics satisfy
the criteria given below.
VCEO = 20 V min.
IC= 20 mA min.
ICBO = 6µA max.
Also, use transistors with a residual volt-
age 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 input 1 and input 2 ter-
minals is approximately 12 mA, and from
the reset input and lock input terminals is
approximately 1.5 mA.]
Also, the open-circuit impedance should
be more than 100 k.
* As shown in the diagram below, from a
non-contact point circuit (proximity
switches, photoelectric switches, etc.)
with a power supply voltage of between
12 and 40 V, the signal can be input
without using an open collector transis-
tor. In the case of the diagram below,
when the non-contact point transistor Q
switches from off to on (when the signal
voltage goes from high to low), the sig-
nal is input.
2) The input mode and output mode
change depending on the DIP switch set-
tings. Therefore, before making any con-
nections, be sure to confirm the opera-
tion mode and operation conditions cur-
rently set.
Note: The LC4H-W does not have the lock input

4. Output mode setting
The output mode can be set with the DIP
switches on the side of the counter.
Make the DIP switch settings before
installing the counter on the panel.
5. Conditions of usage
1) Avoid locations subject to flammable
or corrosive gases, excessive dust, oil,
vibrations, or excessive shocks.
2) Since the cover of the unit is made of
polycarbonate resin, avoid contact with
or use in environments containing methyl
alcohol, benzene, thinners, and other
organic solvents; and ammonia, caustic
sodas, and other alkaline substances.
3) If power supply surges exceed the val-
ues given below, the internal circuits may
become damaged. Be sure to use surge
absorbing element to prevent this from
happening.
4) Regarding external noise, the values
below are considered the noise-resistant
voltages. If voltages rise above these
values, malfunctions or damage to the
internal circuitry may result, so take the
necessary precautions.
Noise wave form (noise simulator)
Rise time: 1 ns
Pulse width: 1 µs, 50 ns
Polarity: ±
Cycle: 100 cycles/second
5) When connecting the operation power
supply, make sure that no leakage cur-
rent enters the counter. For example,
when performing contact protection, if
set up like that of diagram A, leaking cur-
rent will pass through C and R, enter the
unit, and cause incorrect operation.
Diagram B shows the correct setup.

3) The LC4H series use power supply
without a transformer (power and input
terminals are not insulated). In connect-
ing various kinds of input signals, there-
fore, use a power transformer in which
the primary 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.
Once the wiring to be used is completely
installed and prior to installing this
counter, confirm that there is complete
insulation between the wires connected
to the power terminals (2 each) and the
wires connected to each input terminal. If
the power and input lines are not insulat-
ed, a short-circuit may occur inside the
counter and result in internal damage.
In addition, when moving your equipment
to a new installation location, confirm
that there is no difference in environmen-
tal conditions as compared to the previ-
ous location.
(except LC4H-S/AC type)
4) The input signal is applied by the
shorting of each input terminal with the
common terminal (terminal Qfor 8-pin
type, terminal Efor 11-pin type and ter-
minal for screw terminal types). Never
connect other terminals or voltages high-
er than 40 V DC , because it may
destroy the internal circuitry.
5) Transistor output
(1) Since the transistor output is insulat-
ed from the internal circuitry by a pho-
tocoupler, it can be used as an NPN
output or PNP (equal value) output.
(The above example is 11-pin type)

(2) Use the diode connected to the out-
put transistor’s collector for absorbing
the reverse voltage from induced loads.
(LC4H only)
6) When wiring, use shielded wires or
metallic wire tubes, and keep the wire
lengths as short as possible.
Note: With the LC4H 8-pin type and the LC4H-W,
there is no diode between points Iand O.

6) Long periods of continuous operation
in the count-up completed condition (one
month or more) will result in the weaken-
ing of the internal electrical components
from the generated heat and, therefore,
should be avoided. If you do plan to use
the unit for such continuous operation,
use in conjunction with a relay as shown

When using in applications to which
EN61812-1 applies, abide by the follow-
ing conditions.

(for sensor type model with power sup-
ply)
1. Connections between the power sup-
ply and input/output have basic insula-
tion. Use a device with basic insulation
to connect to the I/O terminals.
(for sensor type model without power
supply)
1) This counter employs a power supply
without a transformer, so the power
and input signal terminals are not
insulated.
(1) When a sensor is connected to the
input circuit, install double insulation
on the sensor side.
(2) In the case of contact input, use dual-
insulated relays, etc.
• The load connected to the output con-
tact should have basic insulation.
This counter is protected with basic
insulation and can be double-insulated
to meet EN/IEC requirements by using
basic insulation on the load.
• Applied voltage should be protected
with an overcurrent protection device
(example: 250 V 1A fuse, etc.) that con-
forms to the EN/IEC standards.
2) You must use a terminal block or
socket for installing the pin-type
counter. Do not touch the terminal
section or other parts of the timer unit
while an electric current is applied.
Before installation or removal, confirm
that there is no voltage being applied
to any of the terminals.
3) Do not use this timer with a safety cir-
cuit. For example, when using a timer
in a heater circuit, etc., provide a pro-
tection circuit on the machine side.

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 ×

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

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.

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).

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

and CSA approval for this grade, the product
becomes authorized publicly.

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.
