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 + base socket + input resistor)...... (1)
Input resistor is provided only with current input type.
■ 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
■ CONFORMITY WITH EC DIRECTIVES OR UL
•This equipment is suitable for use in a Pollution Degree
2 environment and in Installation Category II, with the
maximum operating voltage of 300V.
Basic insulation is maintained between signal input and
output. Prior to installation, check that the insulation
class of this unit satisfies the system requirements.
•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 CE/UL requirements. Failure to observe these requirements may invalidate the CE/UL conformance.
■ 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 (90 – 264V for UL),
47 – 66 Hz, approx. 3 – 5VA
24V DC rating: 24V ±10%, approx. 3W
11 – 27V DC rating: 11 – 27V, approx. 3W
110V DC rating: 85 – 150V (110V ±10% for UL), 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 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.
•Be sure that the ventilation slits are not covered 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 supplied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.

INSTALLATION
CHECKING
Loosen the fixing screw at the front of the unit in order to
separate the body from the base socket.
1) Terminal wiring: Check that all cables are correctly connected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
10 – 11 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% of
the full-scale.
4) Alarm operations: Check the alarm operations referring
to the figure below.
5) Check that the output load is 250V AC/600VA or 125V
DC/150W at the maximum. For maximum relay life with
inductive loads, external protection is recommended.
■ 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.

Regular calibration procedure is explained below:
■ CALIBRATION
Warm up the unit for at least 10 minutes.
• Hi Alarm
Increase the input signal from a value lower than the setpoint and check that the relay trips at the setpoint.
• Lo Alarm
Decrease the input signal from a value higher than the setpoint and check that the relay trips at the setpoint.
When the setpoints are shifted, contact M-System’s Sales
Office or representatives.
