1. Counting takes place when the count  
input signal is ON.  
Count input  
2. Counting resumes again when the  
count value reaches 99999999 (full scale  
Reset input  
value) and then returns to “0” with a new  
count input.

3. No measurement takes place when a  
reset is input.  
Note) Count becomes “1” when the reset input is turned OFF while the count signal is being input.  
1) When reset is ON, resetting takes  
place and the count becomes “0”.  
2) Press the front reset button when you  
want to reset manually (only panel  
installation type).  
Note) Be aware that battery life will decrease if the  
count input or reset input are left ON.

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).

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)

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 “  
”.

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 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.  
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.

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.

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

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.

surge is determined by applying a single-  
pole full-wave voltage (several hundred  
to several thousand volt wave for (1.2 ×

terminals.  
3. Miss-count  
This happens if the number of pulses  
does not correspond to the number of  
counts.

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.

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.

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  
(

switched with a  
non-contact ele-  
ment, leak cur-  
rent may flow  
into the counter  
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.  
Approx. 17%  
,
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.

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.

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.
