• Lo LED: Turns on in a tripped condition.
• Hi Setpoint Monitor (+):
Outputs 0 – 10V DC proportional to the setpoint 0 – 100%.
(ex: Set to 8V when you need output ON with input 80% or more.)
• Lo Setpoint Monitor (+):
Outputs 0 – 10V DC proportional to the setpoint 0 – 100%.
(ex: Set to 2V when you need output ON with input 20% or less.)
• Common (–): Used for setpoint monitors.

■ 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 screwdriver
(–) and pull.

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 properly referring to the figure below.
5) Output load: Check the output load corresponds to the table below.

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.
Trip Operation in Power Failure
• Output Code: 1, 2, 4 : both relays turn OFF
• Output Code: 3 : both relays turn ON
