POINTS OF CAUTION
■ CONFORMITY WITH EC DIRECTIVES
•This equipment is suitable for use in a Pollution Degree
2 environment and in Installation Category II, Measurement Category II (output)
Basic insulation (input to output to power: 300V) is maintained. Prior to installation, check that the insulation
class of this unit satisfies the system requirements.
•Altitude up to 2000 meters
•The equipment must be mounted inside a panel.
•The equipment must be installed such that appropriate
clearance and creepage distances are maintained to conform to CE requirements. Failure to observe these requirements may invalidate the CE conformance.
■ POWER INPUT RATING & OPERATIONAL RANGE
•Locate the power input rating marked on the product and
confirm its operational range as indicated below:
85 – 264V AC rating: 85 – 264V, 47 – 66 Hz, approx. 3 – 5VA
24V DC rating: 24V ±10%, approx. 3W
11 – 27V DC rating: 11 – 27V, approx. 3W
110V DC rating: 85 – 150V, approx. 3W
■ GENERAL PRECAUTIONS
•Before you remove the unit from its base socket or mount
it, turn off the power supply and input signal for safety.
■ ENVIRONMENT
•Indoor use
•When heavy dust or metal particles are present in the air,
install the unit inside proper housing with sufficient ventilation.
•Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
•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.
•Be sure that the ventilation slits are not covered with cables, etc.
■ 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.
INSTALLATION
Loosen the fixing screw at the front of the unit in order to
separate the body from the base socket.
■ 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 minus
screwdriver and pull.

CHECKING
SETPOINT ADJUSTMENTS
1) Terminal wiring: Check that all cables are correctly connected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
13 – 14 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
•Relay contact: Check that the output load is 250V AC/
120VA or 125V DC/15W at the maximum (≤0.5A). For
maximum relay life with inductive loads, external protection is recommended.
•Photo MOSFET relay: Check that the output load is 30V
AC/50V DC at the maximum (≤0.5A).

Measure the voltage across the monitor jacks A1 and COM,
and turn the Output 1 Setpoint Adj. until you read the desired value.
• Output 2 Setpoint
Measure the voltage across the monitor jacks A2 and COM,
and turn the Output 2 Setpoint Adj. until you read the desired value.

Trip Operation in Power Failure: Both relays turn off.
■ CALIBRATION
Warm up the unit for at least 10 minutes.
• Hi Alarm
Increase the input signal from a value lower than the setpoint and check that the relay trips at the setpoint, measuring the voltage across the setpoint monitor jacks.
• Lo Alarm
Decrease the input signal from a value higher than the setpoint and check that the relay trips at the setpoint, measuring the voltage across the setpoint monitor jacks.
When the setpoints are shifted, recalibrate the unit according to the “SETPOINT ADJUSTMENTS” explained earlier.
