POTENTIOMETERTRANSMITTER

COMPONENT IDENTIFICATION

INSTALLATION

Use Standard Rack (model: 10BX❑).

TERMINAL CONNECTIONS

Connect the unit as in the diagram below or refer to the

connection diagram label on the unit side.

CHECKING

1) Terminal wiring: Check that all cables are correctly

connected according to the connection diagram.

2) Power input voltage: Check voltage supplied to the rack

(model: 10BX❑). For the DC power source, be sure that

the ripple level is within 10% p-p.

3) Input: Check voltage across the terminal 2 (+) – 3 (–) with

a voltmeter to show 0V at 0% potentiometer input and the

same voltage as that across 1 (+) –␣ 3 (–) at 100% input.

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

scribed specifications.

BEFORE USE ....

Thank you for choosing M-System. Before use, check the

package you received as below.

If you have any problems or questions with the product,

please contact M-System's Sales Office or representatives.

■ PACKAGE INCLUDES:

Signal conditioner ................................................... (1)

■ MODEL NO.

Check that model No. described on specification label is

exactly 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.

24V DC ±10%, approx. 35mA with Voltage Output 1

approx. 55mA with Current Output 1

■ GENERAL

• 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 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 +55°C (23

to131°F)withrelativehumiditywithin30to90%RHinorder

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.

ADJUSTMENT PROCEDURE

This unit is calibrated at the factory with the total resistance

input, therefore you do not need any calibration if you use the

potentiometer's total resistance.

When you don't use the total resistance 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 procedure

1) – 3).

5) Go through the same procedure for Output 2. Extender

Card (model: 10EC) is required to access the Output 2

Adjustments on top of the unit maintaining electrical

connection at the rear connector.

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.
