INSTALLATION

Detach the yellow clamps located at the top and bottom of the unit for separating the body from the base socket.

■ 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) Output: Check that the load resistance meets the described specifications.

ADJUSTMENT PROCEDURE

This unit is calibrated at the factory to meet the ordered specifications, therefore you usually do not need any calibration.

For matching the signal to a receiving instrument or in case of regular calibration, adjust the output as explained in the following.

■ HOW TO CALIBRATE THE DC OUTPUT SIGNAL

Use a signal source and measuring instruments of sufficient accuracy level. Turn the power supply on and warm up for more than 10 minutes.

1) ZERO: Apply the input signals which should lead the calculated result as 0%, and adjust output to 0%.

2) SPAM: Apply the input signals which should lead the calculated result as 100%, and adjust output to 100%.

3) Check ZERO adjustment again.

4) When ZERO value is changed, repeat the above procedure

1) – 3).

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. Apply the input signals which should lead the calculated results as 0%, 25%,

50%, 75% and 100%. Check that the output signal for the respective input signal remains within accuracy described in the data sheet.

When the output is out of tolerance, recalibrate the unit according to the "ADJUSTMENT PROCEDURE" explained earlier.
