INSTRUCTION MANUAL

BEFORE USE ....

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

contents of the package you received as outlined 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.

Conﬁrm Model No. marking on the product to be exactly

what you ordered.

■ INSTRUCTION MANUAL

This manual describes necessary points of caution when

you use this product, including installation, connection and

basic maintenance procedures.

POINTS OF CAUTION

■ GENERAL PRECAUTIONS

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

tilation.

• 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 +55°C

(23 to 131°F) with relative humidity within 0 to 90% RH

in order to ensure adequate life span and operation.

■ WIRING

•Do not install cables (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.

• Install lightning surge protectors for those wires connect-

ed to remote locations. Choose a surge protector with its

maximum surge voltage 40V or less between lines. Rec-

ommended M-System model: MDP-24-1.

■ AND ....

•The unit is designed to function as soon as the input sig-

nal is supplied, however, a warm up for 10 minutes is re-

quired for satisfying complete performance described in

the data sheet.

COMPONENT IDENTIFICATION

INSTALLATION

Set the unit so that its DIN rail adapter is at the bottom.

■ MOUNTING THE UNIT ON A DIN RAIL

A) Hang the upper hook at the rear side of unit on the DIN

rail.

B) Push in the lower in keeping pressing the unit to the

DIN rail.

■ REMOVING THE UNIT

A) Push down the DIN rail adaptor using a minus screw-

driver.

B) Pull out the lower part of the unit.

C) Remove the upper part from the DIN rail.

CHECKING

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

nected according to the connection diagram.

2) Input: Check current with an ammeter. Be sure that

the connected transmitter allows the M5SN’s load value

[230Ω + output load resistance].

3) Output: Check that output load is within the permis-

sible limit of 50 to 350Ω.

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 input signal 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.
