■LOW ALARM: When the signal input goes below
the preset setpoint, the relay provides a tripped
condition
■ON DELAY TIME: The relay status does not change
until after the preset ON Delay Time (TD) once the
signal input goes across the threshold.
■POWER ON DELAY TIME: The relay does not provide
a tripped condition for a duration of the preset Power
ON Delay Time (TDP) after the power supply is turned
on, even when the signal input is in an alarm range.
■ LATCHING OUTPUT: The relay does not return to an
untripped condition once the signal input goes across
the threshold, unless:
(1) the Reset control button is pressed,
(2) the Reset input terminal is closed, or
(3) the power supply is removed.

(thumbwheel switch adjustment; single SPDT output) MODEL M2AS1
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.
■ 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
• 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 con-
form to CE requirements. Failure to observe these re-
quirements may invalidate the CE 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, 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, 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.
• DO NOT apply excessive pressure on the thumbwheel
switches.
■ ENVIRONMENT
•Indoor use
•When heavy dust or metal particles are present in the air,
install the unit inside proper housing with sufficient ven-
tilation.
• 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 (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 sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.
COMPONENT IDENTIFICATION
INSTALLATION
Loosen the fixing screw at the front of the unit in order to
separate the body from the base socket.
■ 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 DI-
MENSIONS.”
TERMINAL CONNECTIONS
Connect the unit as in the diagram below or refer to the con-
nection 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
13 – 14 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 250V AC/
600VA or 30V DC/150W at the maximum. For maximum
relay life with inductive loads, external protection is rec-
ommended.
SETPOINT ADJUSTMENTS
Turn the thumbwheel switch-
es until desired figures in per-
cent are shown. The output
operation is set to “Latching”
when the Deadband Adj. is set
to 00. Monitor LED turns on
when the coil is energized ([in-
put] > [setpoint] for Codes 1 or
4, [input] < [setpoint] for Codes 2 or 3).
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 set-
point and check that the relay trips at the setpoint.
When the setpoints are shifted, contact M-System’s Sales
Office or representatives.
