OPERATION EXPLANATION

UP
LC24-F type
Counts when the
operation signal is ON.
• While the reset input is
ON, the signal time is
not counted and the
display is "0".
Example
ExampleLC24-C type
• Counts when the
operation signal is ON.
• While the reset input is
ON, the signal does
not change.
CAUTIONS
<Non-voltage input type>
1.Since the current from the operation
signal and reset input terminals
[1-3(flush mounting type), E-H
(PC board mounting type)] is small,
use relays and switches which have
high-reliability contact performance.
2.When input signals are triggered
through the transistor ’s open collector,
use a small signal transistor with an
ICBO less than 1 µA, being sure to trig-
ger them with no voltage across the
collector.
3.When connecting the signal input and
reset input wires, do not run them
parallel to high-voltage or power
cables and avoid using the same
conduit. Use shielded wires or metallic
conduits which are as short as possi-
ble. If the floating capacitance of the
wires exceeds 500 pF (approx. 10 m
for parallel wires of 2 mm2), it will
cause malfunctions.
4.Lithium batteries are built in the flush
mounting types. Never throw them into
a fire. Do not dispose of them in trash
intended to be incinerated.
•PC board mounting type—
1.After connecting the external power,
be sure to reset it to make sure that
“0” appears on the display.
2.Battery life is calculated as follows:
t = A
I
t: Battery life (h)
I: Consumption current (mA)
A: Battery capacity when the operating
voltage becomes minimum.
3.Hand soldering:
<Voltage input type>
AC/DC Voltage input type
1.Apply voltage to the signal input termi -
nal. Do not apply voltage to the reset
input terminal. When voltage exceed-
ing the range of the rated input voltage
is applied to the signal input terminal,
or if voltage is applied to the reset ter-
minal, it may cause break-down of
internal elements.
2.Since the current from the reset input
terminal is small, use relays and
switches which have high-reliability
contact performance.
3.When reset is triggered through the
transistor ’s open collector, use a small
signal transistor with an ICBO less than
1 µA, being sure to trigger it with no
voltage across the collector.
4.For external reset, make a temporary
short-circuit between the rear reset ter-
minals [3-4].
DC voltage input type
1.When more than 30 V DC is applied to
the signal or reset input terminals, it
may cause breakdown of internal
elements.
2.For external reset, voltage is applied
between the rear reset terminals
[3-4] to the H level (4.5 to 30 V DC).
In this case, connect (–) to terminal 4
and (+) to terminal 3]. Since they are
polarized, they will not operate with
reverse polarity.

Common
1.When connecting the operation signal
wires [1-2] and reset input wires
[3-4], do not run them in parallel with
high-voltage or power cables. Avoid
running signal or reset wires in a
power conduit. Use shielded wires or
metal conduits which are as short as
possible. If the floating capacitance of
these wires exceeds 500 pF (approxi-
mately 10 m for parallel wires of
2 mm2), it will cause malfunctions.
2.Lithium batteries are built in.
Never throw them into a fire. Do
not dispose of them in trash intended
to be incinerated.
