proximity switches or encoders without addi-
tional devices.
3. Voltage Signal Input:
PNP input types are available.

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) For embedded installation applica-
tions, the screw-down terminal type is
recommended.
Use either the rear terminal block (A 8-
RR) or the 8P cap (AD8-RC) for the 8-
pin type, and the 11P cap (A 8-DP11)
for the 11-pin type. Avoid soldering
directly to the round pins on the unit.
For front panel installation applications,
use the 11-pin type DIN rail terminal
block (A C18004).
3) After turning the unit 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-down 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
he power circuit has no transformer.
When an input signal is fed to two or
more counters 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
damaged.Be careful never to allow such cir-
cuitry. (Figs. A, B and C show the circuitry for
the 11-pin type.)
21
If independent power circuitry must be used,
keep the input contacts or transistors sepa-
rate 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.

less than 1 kΩ.
[When the impedance is 0 W, 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) he input mode and output mode
change depending on the DIP switch set-
tings. herefore, before making any con-
nections, be sure to confirm the opera-
tion mode and operation conditions cur-
rently set.

4. Output mode setting
he output mode can be set with the
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.
DIP
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.
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.

device, use a single-phase or double-
phase insulated power transformer. he
second-phase side must not be ground-
ed.
4) Since the power supply circuitry does
not contain a transformer, be aware that
it is not possible for simultaneous input
from an input contact point or transistor
to a LC4H counter with independent
power supply operation.
5) he input signal is applied by the
shorting of each input terminal with the
common terminal (terminal 1 for 8-pin
type, terminal 3 for 11-pin type and ter-
minal 6 for screw-down terminal types).
Never connect other terminals or volt-
ages higher than DC 40 V, because it
may destroy the internal circuitry.
6) ransistor output
(1) Since the transistor output is insulated
from the internal circuitry by a photo-
coupler, it can be used as an NPN out-
put or PNP (equal value) output. ( he
above example is 11-pin type)
(2) Use the diode connected to the out-

lengths as short as possible.
Note: With the LC4H 8-pin type and the LC4H-W,
there is no diode between points Iand O.

7. CE Marking Certification
1) EMC directive (89/336/EEC)
As a counter unit, the LC4H series con-
forms to EMC directives. Applicable
standards are EN50081-2 and EN50082-
2.
2) Low voltage directive (73/23/EEC)
In order to satisfy VDE0435/Part 2021,
be sure to adhere to the following instal-
lation conditions and precautions.
(1) he counter uses a non-transformer
power supply and the power supply and
input signal terminals are not insulated.
• When a sensor is connected to the
input circuit, install double insulation on
the sensor side.
• With contact-point inputting, use dou-
ble-insulated relays, etc.
(2) Always connect loads insulated with
basic insulation specifications to the out-
put contact points. he counter unit is
also insulated with basic insulation speci-
fications. he combination of the two sat-
isfies VDE, which calls for double insula-
tion.
(3) For the applied power supply, use
one protected by an over-current protec-
tion device that conforms with EN/IEC
standards (e.g. 250 V, 1 A fuse).
(4) During installation, always use a ter-
minal block or the appropriate sockets.
Do not touch the terminals, or other part
of the counter unit while it is on. Before
installation or removal of the unit, first
verify that no voltage is being applied to
any of the terminals.
(5) Do not use the counter in a safety cir-
cuit. When the unit is being used in a cir-
cuit such as a heater circuit, install a pro-
tection circuit on the machine side.
6. Self-diagnosis function
If a malfunction occurs, one of the following displays will appear.
Note 1: When the counter value goes below the minimum value during any of the subtraction, directive, independent, or phase input modes.
Note 2: Includes the possibility that the EEPROM’s life has expired.
