CHECKING
1 ) Terminal wiring: Check that all cables are correctly
connected according to the connection diagram.
2 ) DIP SW setting: Check that the switches are set to
appropriate positions.
3 ) Power input voltage: Check voltage across the termi-
nal 10 – 12 (AC) or 11 – 12 (DC) with a multimeter.
4 ) Input: Check that the input signal is within 0 – 100%
of full-scale.
If the thermocouple, RTD, potentiometer, resistance
or their extension wires, or lead wires of mV input
are broken, the output goes over 100% (below 0%
with downscale protection) due to burnout function.
Confirm the status indicator LED pattern and check
leadwires in such a case.
5 ) Output: Check that the load resistance meets the
described specifications.
I/O RANGING & FINE ADJUSTMENTS
After the DIP SW setting is complete, set up the precise
input and output range using the front control buttons. Be
sure that the front control button function is enabled with
the DIP switch setting.
The front LEDs’ colors and blinking patterns help you to
easily identify the transmitter’s status and confirm the set-
up actions in each step of Calibration Modes. Please read
the following explanations referring to “Calibration Flow
Chart” in Page 6.

PREPARATION (E.G. M3LU2-R4/A, DC POWERED TYPE)
1 ) Mount the DIP-SW-configured M3LU2 on to a DIN
rail.
2 ) Connect the M3LU2 to a simulator and a multimeter
and to a DC power source as shown below.
3 ) Turn the power supply on and wait for 10 minutes.

INPUT & OUTPUT RANGING
[Example] Setting both input and output to 1 – 5V DC
1 ) Run Mode: Confirm that the green LED is blinking
(model M3LU2-x/A) or the green LED turns on (model
M3LU2-x/B).
2 ) Input Configuration Mode: Press MODE button for
longer than 5 seconds until the LD1 red LED is ON
and the LD2 red LED is blinking.
3 ) 0% Input Ranging: Apply the desired minimum input
level (e.g. 1V) from the simulator and push DOWN
button until the LD1 blinks for approx. 2 sec. and then
turns OFF. When you release the button, the LD1 is
returned to ON.
The blinking LD1 means that the value is stored in
the memory. If the LED does not change, the entered
level may be inappropriate: too small a span, or out of
usable range (same for all steps).
