• 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 LED lights turn on when the coil for each relay is energized.

• Examples

For setting the setpoint 1 relay to trip above 20% deviation, turn Setpoint 1 Adj. until you read 2.0V at Setpoint 1

■ 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) Alarm operations: Check the alarm operations referring to the figure below.

4) 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.

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 relay trips at the Hi setpoint (Measure the voltage at the Hi setpoint monitor jacks).

• Lo Setpoint

Decrease the input signal from a value higher than the setpoint and check that the relay trips at the Lo setpoint

(Measure the voltage at the Lo setpoint monitor jacks).

When the setpoints are shifted, recalibrate the unit according to the "ADJUSTMENT PROCEDURE" explained earlier.
