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 that the model number described on the product is
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
WARNING
•Risk of Electrical Shock: The Front Cover is to be Opened
Only by Qualified Service Personnel.
•Before You Remove the Unit from its Base Socket or
Mount it, Turn Off the Power Supply and Input Signal for
Safety.
■ CONFORMITY WITH LOW VOLTAGE DIRECTIVE 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, output and power input. 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.
■ CONFORMITY WITH EMC DIRECTIVE
•Insert noise filters for the power source and the signal I/O
connected to the unit. TDK-Lambda Model MZS-1206-33,
TDK ZCAT 3035-1330 or equivalent is recommended.
•The actual installation environments such as panel configurations, connected devices, connected wires, may affect
the protection level of this unit when it is integrated in
a panel system. The user may have to review the CE requirements in regard to the whole system and employ additional protective measures to ensure the CE conformity.

■ 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 +60°C (23 to 140°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
■ 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.

FRONT VIEW & PROGRAMMING
L1 Monitor LED
The MSEF has three function modes for checking and
programming parameters:
Run mode: Normal operating mode.
Either one or both LEDs are OFF or turned
to red.
Check mode: Parameters can be indicated on the display
in turn.
Either one or both LEDs turns to green.
Normal output as in the Run mode.
Set mode: Used to change parameters.
Either one or both LEDs turns to red/green.
The output is held at the status just before
the MSEF is turned into the Set mode.

• L2 Monitor LED:
The L2 LED is for the Output 2.
• Digital Display:
Run mode:
The 4-digit display indicates the input percentage.
Check/Set mode: Indicates the setting item ID and set values.
Alarm setpoints are represented in 4-digit numbers. The other items are shown with its item ID
(alphanumerical characters) followed by set values.
• UP/DOWN Controls: Pressing UP/DOWN Control Button briefly changes parameter in minimum increments.
Keeping pressing UP/DOWN Control Button increases the speed of change.
Switches the three function modes and the set items.
Run ➾ Check:
Press briefly the MODE Selector.
Run/Check ➾ Set: Press the MODE Selector for 2 seconds.
Next item: In Check/Set mode, press briefly the MODE Selector. Items appear in the order shown in the table below. In Check mode, the unit automatically returns to the Run mode after all the items are displayed in turn.

■ HOW TO MODIFY THE PARAMETERS
1) Press MODE Selector briefly one or more times until the item you need to modify turns up.
Confirm the set value (Check mode).
2) Press MODE Selector for 2 seconds to turn the unit into the Set mode.
[ (1) and (2) can be performed in a reverse order. ]
3) Press UP or DOWN Control Buttons until the display shows a desired setting.
4) Repeat (1) and (3) to change more parameters.
5) Keep pressing MODE Selector for 2 seconds to store the setting and return the unit to the Run mode.
If the buttons are left untouched for longer than 20 seconds, the unit automatically returns from the Check/Set mode to
the Run mode, however, no parameter change performed in the Set mode is effectuated.

INSTALLATION
Detach the yellow clamps located at the top and bottom of
the unit 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.

■ CALIBRATION
Warm up the unit for at least 10 minutes.
• High Setpoint
Increase the input signal from a value lower than the setpoint and check that the relay trips at the Hi setpoint within the setpoint accuracy described in the data sheet.
9 COM
• Low Setpoint
Decrease the input signal from a value higher than the
setpoint and check that the relay trips at the Lo setpoint
within the setpoint accuracy described in the data sheet.
When the setpoints are shifted, please contact M-System’s
Sales Office or representatives.

LIGHTNING SURGE PROTECTION
In order to protect the unit from lightning surges entering
through power supply cables, use of appropriate lightning
surge protectors are recommended. Please contact M-System.
*Input shunt resistor attached for current input.
CHECKING
1) Terminal wiring: Check that all cables are correctly connected 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 300V
AC/600VA or 125V DC/150W at the maximum. For maximum relay life with inductive load, external protection
is recommended.
