POINTS OF CAUTION
■CONFORMITY WITH EU DIRECTIVES
•This equipment is suitable for Pollution Degree 2 and
Measurement Category II (output, transient voltage
2500V). Reinforced insulation (signal input or power in-
put to output: 300V) are maintained. Prior to installa-
tion, check that the insulation class of this unit satisfies
the system requirements.
•The equipment must be mounted inside a panel.
•Altitude up to 2000 meters.
•The equipment must be installed such that appropriate
clearance and creepage distances are maintained to con-
form to CE requirements. Failure to observe these re-
quirements may invalidate the CE conformance.
•The actual installation environments such as panel con-
figurations, connected devices, connected wires, may af-
fect the protection level of this unit when it is integrated
in a panel system. The user may have to review the CE
requirements in regard to the whole system and employ
additional protective measures to ensure the CE conform-
ity.
•Install lightning surge protectors for those wires connect-
ed to remote locations.
■POWER INPUT RATING & OPERATIONAL RANGE
•Locate the power input rating marked on the product and
confirm its operational range as indicated below:
24V DC rating: 24 V ±10%, approx. 0.5W
■GENERAL PRECAUTIONS
•Before you remove the unit 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 -20 to +55°C
(-4 to +131°F) with relative humidity within 30 to 90%
RH in order to ensure adequate life span and operation.
■WIRING
•Do not install cables 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.
■AND ....
•The unit is designed to function as soon as power is sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected 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.
If the RTD or its extension wires are broken, the output
goes over 100% (below 0% with downscale protection) due
to the burnout function. Confirm the status indicator
LED pattern and check leadwires in such a case.
4) Alarm operations: Check the alarm operations referring
to the figure below.
5) Output load: Check that the output load is 250 V AC /
500 VA or 125 V DC / 60 W. For maximum relay life with
inductive load, external protection is recommended.

MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Warm up the unit for at least 10 minutes.
• H Setpoint
Increase the input signal from a value lower than the
setpoint and check that the relay trips at the H setpoint
within the setpoint accuracy described in the data sheet.
• L Setpoint
Decrease the input signal from a value higher than the
setpoint and check that the relay trips at the L setpoint
within the setpoint accuracy described in the data sheet.
When the setpoints are shifted, recalibrate the unit using
the PC Configurator Software (model: M6CFG).
