■ DIN RAIL MOUNTING
Set the base socket so that its
DIN rail adaptor is at the bottom. Position the upper hook
at the rear side of base socket
on the DIN rail and push in the
lower. When removing the
socket, push down the DIN rail
adaptor utilizing a screwdriver
(–) and pull.

CHECKING
POINTS OF CAUTION
1) Terminal wiring: Check that all cables are correctly
connected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal 7
– 8 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% of
the full-scale.
4) Alarm operations: Check the alarm operations referring
to the figure below.
5) Output load: Check that the output load is 380V AC/
100VA or 125V DC/30W at the maximum. For maximum
relay life with inductive load, external protection is recommended.
■ GENERAL
• Before you remove the unit from its base socket or mount it,
turn off the power supply and input signal for safety.
■ WIRING
• Do not install cables (power supply, input and output) close
to noise sources (relay drive cable, high frequency line, etc.).
• Do not bind these cables together with those in which noises
are present. Do not install them in the same duct.

■ ENVIRONMENT
• When heavy dust or metal particles are present in the air,
install the unit inside proper housing and ventilate it.
• Do not install the unit where it is subjected to continuous
vibration. Do not apply physical impact to the unit.
• Environmental temperature must be within -5 to +55°C (23
to 131°F) with relative humidity within 30 to 90% RH in order
to ensure adequate life span and operation.

MAINTENANCE
• Trip operation in power failure: terminals 1 – 3, 9 – 11 turn
ON.
ADJUSTMENT PROCEDURE
Adjustment procedure for the Hi and Lo setpoints are as
follows:
■ HOW TO ADJUST ALARM SETPOINTS
The monitor jacks output 0 – 10V DC in proportion to the 0
– 100% setpoints.
• Hi Setpoint
Measure the voltage at the Hi setpoint monitor jacks and
turn the Hi Adj. until you read a desired value.
• Lo Setpoint
Measure the voltage at the Lo setpoint monitor jacks and
turn the Hi Adj. until you read a desired value.
Regular calibration procedure is explained below:
■ CALIBRATION
Warm up the unit for at least 10 minutes.
• Hi Setpoint
Increase the input signal from a value lower than the setpoint
and check that the relay trips at the Hi setpoint (Measure the
voltage at the Hi setpoint monitor jacks).
• Lo Setpoint
Decrease the input signal from a value higher than the
setpoint and check that the relay trips at the Lo setpoint
(Measure the voltage at the Lo setpoint monitor jacks).
When the setpoints are shifted, recalibrate the unit according
to the "ADJUSTMENT PROCEDURE" explained earlier.
