■ MODEL NO.

Check that model No. described on speciﬁcation label is ex-

actly what you ordered.

■ INSTRUCTION MANUAL

This manual describes necessary points of caution when you

use this product, installation, connection and basic mainte-

nance procedures.

POINTS OF CAUTION

■ POWER INPUT RATINGS

• Power input ratings are speciﬁed by the model number

sufﬁx code. Check the power input voltage for the unit on

the speciﬁcation label.

AC power: rating ±10%, 50/60 ±2 Hz, approx. 2VA

DC power: rating ±10%, approx. 2W

(85 – 150V for 110V rating)

■ 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) for the transmitter and -10 to +55°C (14 to

131°F) for the probe, with relative humidity within 15 to

85% RH for the probe, 30 to 90% RH for the transmitter in

order to ensure adequate life span and operation.

• Do not cover the ventilation slits with cables, etc.

■ 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 sup-

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

isfying complete performance described in the data sheet.

• DIN Rail Mounting

Set the base socket so that its

DIN rail adaptor is at the bot-

tom. 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.



■ CURRENT PROBE

Mount the sensor so that the conductor passes near the

center of the sensor and at right angle to the sensor circle.

Otherwise, the position sensitivity may increase.

In order to separate the connection, pull out the sensor end

from the connector.

Use binding straps for ﬁxing the position of the probe with

the attachments.

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

7 – 8 with a multimeter.

3)Input: Check that the range selector switch is properly

set to match the input range. Check that the input

signal is within 0 – 100% of the full-scale.

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 suf-

ﬁcient 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.
