■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 EU DIRECTIVES, UK LEGISLATION OR UL
• This equipment is suitable for Pollution Degree 2, Meas-
urement Category II (output, transient voltage 2500V)
and Installation Category II (transient voltage 2500V).
Reinforced insulation (signal input or output to power in-
put: 300V) and basic insulation (signal input to output:
300V) are maintained. Prior to installation, check that
the insulation class of this unit satisfies the system re-
quirements.
• 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 con-
form to CE/UKCA/UL requirements. Failure to observe
these requirements may invalidate the CE/UKCA/UL
conformance.
• The actual installation environments such as panel con-
figurations, connected devices, connected wires, may af-
fect the protection level of this unit when it is integrated
in a panel system. The user may have to review the
CE/
UKCA
requirements in regard to the whole system and
employ additional protective measures to ensure the
CE/
UKCA
conformity.
• Install lightning surge protectors for those wires connect-
ed to remote locations.
■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 ca-
bles, etc.
■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.

DIN Rail Adaptor
■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.
■WALL MOUNTING
Refer to “EXTERNAL DIMENSIONS.”
TERMINAL CONNECTIONS
Connect the unit as in the diagram below or refer to the connection diagram on the side of the unit.
When an input resistor is provided with the module, attach it together with input wiring to the input screw terminals.

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
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.

SETPOINT ADJUSTMENTS
Turn the thumbwheel switches until desired figures in per-
cent are shown. Output 1 is for Hi trip, while Output 2 is
for Lo. Monitor LED turns on when the coil is energized
([input] > [setpoint] for Output 1, [input] < [setpoint] for
Output 2).
MAINTENANCE
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 set-
point 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.
LIGHTNING SURGE PROTECTION
M-System offers a series of lightning surge protector for
protection against induced lightning surges. Please contact
