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.

This equipment is for use in general industrial environ­ments, therefore may not be suitable for applications which
require higher level of safety (e.g. safety or accident preven­tion systems)or of reliability (e.g. vehicle control or combus­tion control systems).
For safety, installation and maintenance of this equipment
must be conducted by qualified personnel.

■ PACKAGE INCLUDES:

Signal conditioner

(body + base socket + CJC sensor) ................................. (1)

■ MODEL NO.

Confirm that the model number described on the product is
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.

■ SYMBOLS USED ON THE PRODUCT AND IN THIS MANUAL

The symbol indicated on the equipment, means that
the user must refer to the related parts in the manual for
safe operation of the equipment. It is essential to read the
instructions wherever the symbol appears in the manual.

WARNING: is reserved for conditions and actions that

can cause serious or fatal injury.

CAUTION : is reserved for conditions and actions that can

cause injury or instrument damage.

  WARNING

■ INSULATION CLASS

Basic insulation (Signal input or output to Power input: 300
V) is maintained.
If insulation failure may result in equipment, hazardous
voltage (maximum 240 V) may result to signal input and
then electric shock may cause.
Prior to installation, prepare supplemental insulation
(equivalent basic insulation) between signal input and ex­ternal circuits.

  CAUTION

■ REGARDING SAFETY

If equipment is not used in a manner not specified by M­System, the protection provided by the equipment may be
impaired.

■ CONFORMITY WITH LOW VOLTAGE DIRECTIVE OR UL

•This equipment is suitable for use in a Pollution Degree
2 environment and in Installation Category II (transient
voltage 2500 V).

•Altitude up to 2000 meters.

•The equipment must be mounted inside a panel.

•The equipment must be installed such that appropriate

clearance and creepage distances are maintained to con­form to EU/UL requirements. Failure to observe these
requirements may invalidate the EU/UL conformance.

■ CONFORMITY WITH EMC DIRECTIVE

•Insert a noise filter for the power source connected to the
unit. TDK-Lambda Noise Filter Model RSNA-2006 or
equivalent is recommended.

•The actual installation environments such as panel con­figurations, connected devices, connected wires, may affect
the protection level of this unit when it is integrated in a
panel system. The user may have to review the CE re­quirements in regard to the whole system and employ ad­ditional protective measures to ensure the CE conformity.

■ SIGNAL INPUT

This terminal is used for signal input.
Do not connect or measure to the circuits including tran­sient voltage 2500 V.
Refer to “INPUT SPECIFICATIONS” in detail.

■ OUTPUT TERMINAL

Never use the output terminal under any load that exceeds
the rated values. Otherwise it will impair prescribed perfor­mance and cause burning of the equipment itself.

■ WIRING

•For wiring connection, refer to “TERMINAL CONNEC­TIONS” and wire correctly. Fire, electric shock and fail­ure cause if wire are incorrectly connected.

•Wire using vinyl insulated power cable that meet input
voltage and load current for equipment and screw by an
adequate torque.
Loose screws may abnormally generate heat and fire
may cause. (Proper tightening torque [N·m] : 0.98 – 1.18)

•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.

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:

■ AC Power

M2: 100 – 240 V AC, 50 – 60 Hz, maximum 6 VA
(85 – 264 V AC, 47 – 66 Hz)

■ DC Power

R: 24 V DC (24 V ±10%), maximum 3.5 W
P: 110 V DC (85 – 150 V), maximum 3.5 W

■ 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
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 +55°C
(23 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.

■ 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.

•Never use the internal relay under any load that exceeds
the rated contact values including the switching capaci­ties (contact voltage and contact current).
Otherwise it will impair prescribed performance (insula­tion failure, contact welding, contact failure) and cause
burning of the Relay itself.
