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).
