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) ❇Count becomes “1” when the reset input is turned OFF while the count signal is being input.
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
(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.
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).
2. Voltage input type
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.
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.

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.

2. Use as small a diode (D) as possible in the

terminals 3 and 4 during reset input meets
the standard value (0.5 V).

higher.)

7. Waterproof construction (Installation frame type)
The operation part of the panel installation type (Installation frame type) is constructed to prevent water from entering
the unit and a rubber gasket is provided to
prevent water from entering the gap between the unit and the panel cutout. There
must be sufficient pressure applied to the
rubber gasket to prevent water from entering. Be sure to use the installation reinforcement screws when installing the
frame (ATH3803).
Note) Make sure that H (reset ON) level is at least 4.5
V.

Note) The one-touch installation type is not
waterproof.

ganic solvents such as methyl alcohol,
benzene and thinner, or strong alkali substances such as ammonia and caustic soda.
10. Cautions regarding battery replacement
1) Remove wiring before replacing the
battery. You may be electrocuted if you
come into contact to a part where high
voltage is applied.
2) Make sure you are not carrying a static
electric charge when replacing the battery.
3) Battery replacement procedure
1 One-touch installation type
1. Using a tool remove the up/down hook
of the case.
2. Pull the unit away from the case.
3. Remove the battery from the side of the
unit. Do not touch the display or other
parts.
4. Before inserting wipe clean the surface
of the battery.
5. Insert the battery with the + and – sides
in the proper position.
6. After replacing the battery return the
unit to the case. Verify that the hook of the
case has properly engaged.
7. Before using press the reset button on
the front.

changes drastically.
2) In places where humidity is high and
there is the possibility of dew. (When dew
forms the display may vanish and other

9. Conditions of use
1) Do not use in places where there is
flammable or corrosive gas, lots of dust,
presence of oil, or where the unit might be
subject to strong vibrations or shocks.
2) Since the cover is made of polycarbonate resin, do not use in places where the
unit might come into contact with or be exposed to environments that contain or-
