basic maintenance procedures.

POINTS OF CAUTION

■GENERAL PRECAUTIONS

• Before you remove the unit or mount it, turn off the power

supply and input signal for safety.

■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.

■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

satisfying complete performance described in the data

sheet.

TERMINAL CONNECTIONS

Connect the unit as in the diagram below or refer to the connection diagram on the side of the unit.

Ground the screw terminal at the bottom for RFI protection if necessary. When grounded, dielectric strength between output

signal line and ground is of 50V DC, though it is of 500V AC when not grounded.

WIRING INSTRUCTIONS

■EURO TYPE TERMINAL

Applicable wire size: 0.25 – 1.5 mm2

Stripped length: 7 mm

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

connection.

3) Output: Check that the load is within the permissible

limit including wiring resistance.

Load Resistance (Ω) = Supply Voltage (V) – 12 (V)

0.02 (A)

(including leadwire resistance)

4) When you check the output signal, connect an ammeter

of which the internal resistance is of 10Ω max. to the

monitor terminals.

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.
