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 (body + CJC Sensor)...................... (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.

The unit is programmable using the PC Conﬁgurator Soft-

ware. For detailed information on the PC conﬁguration,

refer to the W2CFG users manual. The W2CFG PC Con-

ﬁgurator Software is downloadable at M-System’s web site:

http://www.m-system.co.jp.

POINTS OF CAUTION

■ POWER INPUT RATING & OPERATIONAL RANGE

• Locate the power input rating marked on the product and

conﬁrm its operational range as indicated below:

100 – 240V AC rating: 85 – 264V, 47 – 66 Hz, approx. 5 – 7VA

24V DC rating: 24V ±10%, approx. 3W

■ GENERAL PRECAUTIONS

• Before you remove the unit from its base socket 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 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 30 to 90% RH

in order to ensure adequate life span and operation.

• Be sure that the ventilation slits are not covered with ca-

bles, 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 20 minutes is required for

satisfying complete performance described in the data

sheet.

• With voltage output, do not leave the output terminals

shortcircuited for an extended time period. The unit is

designed to endure it without breakdown, however, it may

shorten appropriate life duration.

■ DIN RAIL MOUNTING

Set the base socket so that

its DIN rail adaptor is at

the bottom. 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 minus

screwdriver and pull.

TERMINAL CONNECTIONS

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

OUTPUT RANGING

The internal DIP switch setting is required to select output

types before setting a precise output range using PC Con-

ﬁgurator Software (model: W2CFG).

For detailed information on the PC conﬁguration, refer to

the W2CFG users manual.

CHECKING

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

nected according to the connection diagram.

2) Check DIP switch setting.

3) Power input voltage: Check voltage across the terminal

10 – 11 with a multimeter.

4) Input: Check that the input signal is within 0 – 100% of

the full-scale.

If the thermocouple or its extension wires are broken, the

output goes over 100% (below 0% with downscale) due to

burnout function. Conﬁrm the status indicator LED pat-

tern and check leadwires in such a case.

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

scribed speciﬁcations.

6) LED: Conﬁrm that the LEDs indicate the normal oper-

ating mode.

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 using the PC Conﬁgurator

Software (model: W2CFG).

LIGHTNING SURGE PROTECTION

M-System offers a series of lightning surge protector for

protection against induced lightning surges. Please contact

M-System to choose appropriate models.
