Notes) 1. When using contact input, since current flow is small from terminals 1 and 3 on the panel mounting type and terminals e to t and S to F on the PC board

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.
t = A/I
t: battery life [h]
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).

DC to count input terminals 1 and 2, and
reset input terminals 3 and 4 will cause
damage to the internal elements.
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).
3. Free voltage input type
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.
Note) ❇Count becomes “1” when the reset input is turned OFF while the count signal is being input.
0
Notes) 1. Do not reverse the polarities when connecting the DC voltage for the backlight.
2. 2 and 4. (The input and reset circuits are functionally insulated.)
3. When using transistor (Tr) input, use the right as a guide. (Collector withstand voltage Q 50 V, leakage current < 1 μA)
4. 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.
Explanation of operation
1. Counting takes place when the count
input signal is ON.
2. Counting resumes again when the
count value reaches 99999999 (full scale
value) and then returns to “0” with a new
count input.
3. No measurement takes place when a
reset is 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
For both panel mounting and PC board
mounting types
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.
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.
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

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.

Notes) 1. Use the following as a guide for choosing

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).

higher.)
