• 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.

* “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

models).(The 1st digit is set using the [UP] key or [DOWN] key in settings where there is no decimal point (this applies

only to 4-digit models).)

• Setting the pre-scaling value

QHolding down the [SET/LOCK] key, press the key for the first digit to access the pre-scaling value setting mode.

Example) 4-digit type Example) 6-digit type

WWhen the setting mode has been accessed, release the [SET/LOCK] key.

EUse the [UP] or [DOWN] key to set the pre-scaling value (this applies only to 4-digit models).

Select either: 0.001 to 9.999 (4-digit) or 0.001 to 99.999 (6-digit)

RPress the [RESET] key to set the displayed pre-scaling value and return to normal operation.

• Setting the one-shot output time

QHolding down the [SET/LOCK] key, press the key for the third digit to access the one-shot output time setting mode.

WWhen the setting mode has been accessed, release the [SET/LOCK] key.

EEach time the 1st-digit [UP] key is pressed, the one-shot output time changes in the following sequence, moving to the

right:

(With a 4-digit type, the [DOWN] key can also be used to move to the left.)

RPress the [RESET] key to set the displayed one-shot output time and return to normal operation.

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.

IN1 or IN2 works as an input block

(gate) for the other input.

• Example where IN1 is the counting input 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. *n: Set value 2

* “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.

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.)

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.

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 kΩ.

[When the impedance is 0 Ω, 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 kΩ.

* 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

R,.

Note: The LC4H-W does not have the lock input

141

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.

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

in the circuit in the diagram below.

PRECAUTIONS IN USING THE LC4H SERIES

7. Compliance with the CE marking

When using in applications to which

EN61812-1 applies, abide by the follow-

ing conditions.

• Overvoltage category II, pollution level

(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

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 Ωper 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

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).

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.

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.
