POINTS OF CAUTION
■ POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and confirm its operational range as indicated below:
AC power : Rating ±10%, 50/60 ±2 Hz, approx. 2VA
DC power : Rating ±10%, approx. 1.3W or 85 – 150V, approx. 1.3W for 110V rating
Setpoint 1 Adj. & LED
Setpoint 2 Adj. & LED
■ GENERAL PRECAUTIONS
• Before you remove the unit from its base socket or mount it, turn off the power supply and input signal for safety.
• Explanations
Setpoint 1 and Setpoint 2 Adjustments are used to set the alarm setpoints.
A -5 – +5V DC is output at the setpoint monitor jacks across the COM jack, proportional to the setpoint -50 – +50%.
The LEDs turn on when the coil for each relay is energized.
■ 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 -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.
• Examples
For setting the setpoint 1 relay to trip above 20% deviation, turn Setpoint 1 Adj. until you read 2.0V at Setpoint 1
Monitor.
INSTALLATION
Detach the yellow clamps located at the top and bottom of the unit for separate the body from the base socket.
■ 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 supplied, however, a warm up for 10 minutes is required for satisfying complete performance described in the data sheet.
■ 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 minus 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) Alarm operations: Check the alarm operations referring to the figure below.
5) Output load: Check that the output load is 380 V AC/120
VA or 125 V DC/30 W at the maximum. 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.
• 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.
