CHECKING
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) Output load: Check that the output load is 300V AC/
600VA or 125V DC/150W at the maximum. For maximum
relay life with inductive load, external protection is recom-
mended.
ALARM RELAY OPERATIONS
• Trip operation in power failure: terminals 1 – 3, 9 – 11 turn ON.
MAINTENANCE
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 trip point remains within the accuracy
described in the data sheet.
• Lo Setpoint
Decrease the input signal from a value higher than the
setpoint and check that the trip point remains within the
accuracy described in the data sheet.
When the trip points are out of tolerance, contact M-System’s
Sales Office or local representatives.
