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.

■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 sup-

plied, however, a warm up for 10 minutes is required for

Torque: 0.8 N·m

PIPING

The pneumatic inlet is female screwed of Rc 1/4” (1/4” NPT

optional with a ﬁtting). Tightening torque is at the maxi-

mum of 12 N·m. Check that there is no air leak at the con-

nection after sealing it.

CHECKING

1) Terminal wiring: Check that all cables are correctly con-

nected according to the connection diagram.

2) Power input voltage: Check voltage across the terminal

1 – 2 with a multimeter.

3) Input: Check that there is no air leak at the pneumatic

connection.

4) Output: Check that the load resistance meets the de-

scribed speciﬁcations.

ADJUSTMENT PROCEDURE

This unit is calibrated at the factory to meet the ordered

speciﬁcations, therefore you usually do not need any cali-

bration.

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 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 0% input and adjust output to 0%.

2) SPAN: Apply 100% input and adjust output to 100%.

3) Check ZERO adjustment again with 0% input.

4) When ZERO value is changed, repeat the above proce-

dure 1) – 3).

MAINTENANCE

Regular calibration procedure is explained below:

■CALIBRATION

Warm up the unit for at least 10 minutes. Apply 0%, 25%,

50%, 75% and 100% input signal. Check that the output

signal for the respective input signal remains within accu-

racy described in the data sheet. When the output is out of

tolerance, recalibrate the unit according to the “ADJUST-

MENT PROCEDURE” explained earlier.
