When installing the one-touch installation type model, make sure
that the installation spring does not pinch the rubber gasket.
To prevent the installation spring
from pinching the rubber gasket:
1. Set the rubber gasket on both
ends of the installation spring
(left and right).
2. Confirm that the installation
spring is not pinching the rubber
gasket, and then insert and fix the
installation spring in place from the
rear of the timer unit.

Explanation of operation
1. Time measuring takes place when the
start input is ON.
2. When the elapsed (measured) time
reaches full scale it returns to “0”, and
then measuring starts again from “0”.
3. When reset input is ON, the display
becomes “0”. You cannot measure during
reset input.
For PC board mounting type the display
disappears while the reset input is ON;
however, the display reads “0” when the
reset input turns OFF.
4. Press the front reset button if you want
to perform a manual reset (for panel
installation type)

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.
2) Since the current flow is very small
from the start 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. 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.
3) When wiring, try to keep all the input
lines to the start 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). 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
hour meter 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: LH2H 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 start 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 hour
meter will not work if reversed.
3) When wiring, try to keep all the input
lines to the start 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 start 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 start 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.

• There is minimal dust and no corrosive
gas.
• There is no combustible or explosive
gas.
• There is no mechanical vibration or
impacts.
• There is no exposure to direct sunlight.
• Located away from large-volume
electromagnetic switches and power
lines with large electrical currents.
3) Connect a breaker that conforms to
EN60947-1 or EN60947-3 to the voltage
input section.
4) Applied voltage should be protected
with an overcurrent protection device
(example: T 1A, 250 V AC time lag fuse)
that conforms to the EN/IEC standards.
(Free voltage input type)
7. Terminal connection
Tighten the terminal screws with a torque
of 0.8 N·cm or less.
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).
( At IF = 20 µA, forward voltage 0.1 and
higher.)
