• Explanations
Hi and Lo setpoint rotary switches are used to set the alarm
setpoints.
The Hi and Lo LED lights turn on when the coil for each relay
is energized.
• Examples
For setting the relay to trip above 80% of the full-scale input
signal, set the Hi rotary switch (x10) to "8", while the switch
(x1) to "0".

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 +60°C (23
to 140°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.
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
ncrease 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.
When the trip points are out of tolerance, contact M-System's
Sales Office or local representatives.
