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
■POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
AC power: Rating ±10%, 50/60 ±2 Hz, approx. 2VA
DC power: Rating ±10%, approx. 2W
■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.
■WIRING
• 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.
■AND ....
• The unit is designed to function as soon as power is sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.

• Explanations
Hi and Lo setpoint rotary switches are used to set the alarm
setpoints.
The Hi and Lo LED, turn on when the coil for each relay is
energized.
• Examples
For setting the relay to trip above 80% of the full-scale input
signal, set the Hi rotary switch (×10) to “8”, while the switch
(×1) to “0”.
INSTALLATION
Detach the yellow clamps located at the top and bottom of
the unit for separate the body from the base socket.

Shape and size of the base socket
are slightly different with various
socket types.
■DIN RAIL MOUNTING
Set the base socket so that its
DIN rail adaptor is at the bot-
tom. Hang 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.
■WALL MOUNTING

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
7 – 8 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) Output load: Check that the output load is 380V
AC/120VA or 125V DC/30W at the maximum . For maxi-
mum relay life with inductive load, external protection is
recommended.

MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Warm up the unit for at least 10 minutes.
• Hi Setpoint
Increase the input signal from a value lower than the set-
point and check that the trip point remains within the
accuracy described in the data sheet.
• Lo Setpoint
Decrease the input signal from a value higher than the
setpoint and check that the trip point remains within the
accuracy described in the data sheet.
When the setpoints are shifted, please contact M-System’s
Sales Office or representatives.
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.
