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:
24V DC rating: 24V ±10%, approx. 80mA with dual alarm
■GENERAL PRECAUTIONS
• Before you remove the unit 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.
• Be sure to put the terminal cover on while the power is
supplied.
■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.

• Single Alarm Trip
Simulate an input for the desired setpoint, then turn the
top mounted screw driver adjustment slowly clockwise until
the output relay trips.
• Dual Alarm Trip
Set the Dual Output 1 setpoint in the same manner as con-
figuring the single alarm trip using the upper adjustment.
Then, repeat the procedure to set the Dual Output 2 set-
point using the lower adjustment.
• Hi/Lo Alarm Trip
Lo Setpoint: Simulate an input for the desired setpoint,
then turn the screw driver adjustment slowly counterclock-
wise until the output relay trips.
Hi Setpoint: Simulate an input for the desired setpoint, then
turn the screw driver adjustment slowly clockwise until the
output relay trips.
INSTALLATION
Use Standard Rack (model: 10BXx).

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage supplied to the rack
(model: 10BXx). For the DC power source, be sure that
the ripple level is within 10% p-p.
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 trip points 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
