LC2H
Cautions for use
1. Non-voltage input type
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).

board mounting types

or

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.
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.

3. Free voltage input type
6. Environment for use
1) Ambient conditions
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.
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.
• 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)
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.
• 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.
(Free voltage input type)
4. How to reset multiple panel
mounting type counters all at once
(input is the same for count)
t = A/I
t: battery life [h]
Non-voltage input type
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).

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).
2. Voltage input type
( At IF = 20 µA, forward voltage 0.1 and
higher.)
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.

Changing the preset value
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 “
”.

LC2H
Cautions for use
1. Input and output connection
1) Input connection
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 kΩ.
(When the impedance is 0 Ω, 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 kΩ.
(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.
As NPN output
(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.

3) Have the power supply voltage pass through a switch or relay
so that it is applied at one time.

COUNTER-RELATED TERMINOLOGY
TYPES OF COUNTERS
8. Recount
When counting is up, the counter display
resets to zero and counting restarts.
5. Automatic Reset
1. Electro Preset Counter
When counting is up, internal circuitry is
activated to automatically reset the
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.
9. Down Count
Numbers are counted down one by one
6. Reset Signal Width
from a preset number.
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.
2. Electro Magnetic Counter
A magnet is magnetized and demagne-
tized to drive the dial and count up num-
bers.
10. Up Count
Numbers are counted up one by one
from zero.
7. Reset time
RATING
11. Up/Down Count
Numbers are counted up or down
depending on input
conditions.
This is the time from the moment a reset
signal is sent to the instant the counter is
ready to start counting again.
1. Rated Operating Voltage
The voltage is applied to start the
counter.
OTHERS
12. Rejection (gate) Input
This signal is used to keep the counter
from counting.
COUNTINGS
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.
1. Pulse
This is a voltage or current signal sent at
intermittent time intervals.
OUTPUTS
2. Count
1. Count Up
Pulses are used to count up and down.
When a preset number is reached, the
2. Anti-surge
output circuit sends a signal.
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.
3. Miss-count
This happens if the number of pulses
does not correspond to the number of
counts.
2. Retained Output
The output is held until a reset signal is
sent.
4. Hertz
3. One Shot Output
Surge waveform
This unit of counting speed is used to
give the number of counts per one

3. Noise Immunity
Time
This is the strength against external
noise. Relay noise tests, noise simulator
tests, etc. are conducted.
3. Manual Reset
The counter is manually reset.
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).
4. Remote Reset
A signal is sent from a remote point to
the reset terminal so as to reset the
counter.
7. Over Count
Counting continues beyond a preset
number.

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.

voltage of about 2 to 3 times the
power supply voltage.
2. Type of Load and Inrush Current
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.
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.

3. Connection of input
(Except for LC4H-S/AC type)
The LC4H series use power supply with-

nals are not insulated). In connecting
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.

PRECAUTIONS IN USING THE COUNTER
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

ment, leak cur-
rent may flow

and cause it to

5. Superimposed surge of power
supply
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.
Cautions for use
(common for all models)
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."
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.

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.

Power line etc.
8. Checking the actual load
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.)
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.
6. Signal input
3. Control output
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.
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.
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.
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).
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.

INSTALLING DIN SIZE COUNTER
Installation methods
1. Surface mount
2) How to mount the 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
1) For the counters of LC4H series, use
the pin type 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
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
1. International Standards
IEC standard
3. Europe
EN 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.
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.
2. North America
(1) Germany
UL (Underwiters Laboratories Inc.)
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.
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.
LISTING MARK
VDE
Fig. 1
RECOGNITION MARK
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.
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.
Fig. 2
CSA (Canadian Standards Association)
Certification
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.
TÜV certification can be obtained from any of the 14
TÜVs throughout Germany and has the same
effectiveness as obtaining VDE certification.

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.

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.

CE MARKINGS OVERVIEW
Counter, Hour Meter conforming to
CE markings and EC
EN/IEC standards
directives
The Timer, Counter, Hour Meter shown below conform to both EN and IEC standards,
and may display the CE markings.
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.

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.
If the relevant EN standard does not
exist, it is necessary to obtain approval
based on the relevant IEC standard or, if
the relevant IEC standard does not exist,
the relevant standard from each country,
such as VDE, BS, SEMKO, and so forth.
