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) Relay operations: Confirm that the relays operate prop-
erly referring to the figure below.
5) Output load: Check the output load corresponds to the
table below.
For maximum relay life with inductive load, external
protection is recommended.
ALARM RELAY OPERATIONS
Trip Operation in Power Failure
•
Output Code: 1, 2, 4
: both relays turn OFF
•
Output Code: 3
: both relays turn ON
POINTS OF CAUTION
■
GENERAL
• Before you remove the unit from its base socket or mount it,
turn off the power supply and input signal for safety.
■
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.
■
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.
■
AND ....
• The unit is designed to function as soon as power is
supplied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data sheet.
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.
