CAUTIONS FOR USE
Non-voltage input type
Common to both the panel mounting type, and the PC board mounting type
• 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.
• Sincethecurrentowisverysmallfromthecount
input and reset input terminals ( and on the panel
mounting type and terminals to and to on the
PC board mounting type) please use relays and switches
with high contact reliability.
• 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.
• 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oatingcapacitanceof
these wires exceeds 500 pF (10 m 32.808 ft for parallel wires
of 2 mm
2
0.003 in
2
).
Whenusing2kHzmode,usewithawiringoatingcapacitance
of 120 pF (3 m 9.843 ft for parallel wires of 2 mm
2
0.003 in
2
).
In particular, when using shielded wiring, be careful of the
capacitance between wires.
PC board mounting type
• For external power supply use manganese dioxide or
lithium batteries (CR type: 3V).
• Alwaysresetafterexternalpowerisappliedandconrm
that the display reads "0".
• Make the wiring from the battery to the counter unit as
short as absolutely possible. Also, be careful of polarity.
• 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]
• 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).
Voltage input type
• Be aware that applying more than 30 V DC to count input
terminals and , and reset input terminals and
will cause damage to the internal elements.
• For external resetting use H level (application of 4.5 to
30 V DC) between reset terminals and of the rear
terminals. In this case, connect (+) to terminal 3 and (-)
to terminal . This is the valid polarity; therefore, the
counter will not work if reversed.
• 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oatingcapacitanceof
these wires exceeds 500 pF (10 m 32.808 ft for parallel wires of
2 mm
2
0.003 in
2
).
Free voltage input type
• Use count input terminals and for free voltage input
and reset terminals and for non-voltage input.
• 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.
• Sincethecurrentowisverysmallfromresetinput
terminal , please use relays and switches with high
contact reliability.
• 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.
• To reset externally, short reset input terminals and
on the rear.
• Input uses a high impedance circuit; therefore, erroneous
operationmayoccuriftheinuenceofinductionvoltage
is present. If you plan to use wiring for the input signal
that is 10 m 32.808 ft or longer (wire capacitance 120
pF/m at normal temperature), we recommend the use of
aCRlterortheconnectionofableederresistor.
Backlight luminance
To prevent varying luminance among backlights when
using multiple backlight types, please use the same
backlight power supply.

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).
