/ control buttons, and PC Software. (The Option B type is for  
the field configuration only.)

The internal DIP switches are used to configure input and  
output type. Once the module is configured, precise ranges  
are set up with the front control buttons using a simulator

turned on. Set the switches with the power supply removed.  
Selectable I/O type and ranges are listed in Table 5 and 6.

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 terminal 11 – 12 with a multimeter.  
4) Input: Check that the input signal is within 0 – 100% of full-scale.  
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.  
The front LEDs’ colors and flashing patterns help you to easily identify the transmitter’s status and confirm the setup actions  
in each step of Calibration Modes. Please read the following explanations referring to “Calibration Flow Chart” below.

ing.  
5) UseUP(increase)andDOWN(decrease)buttonstoadjust  
the output to 100%.  
1) Mount the DIP-SW-configured M3LDY on to a DIN rail.  
2) Connect the M3LDY to a simulator and a multimeter and  
to a DC power source as shown to the right.  
3) Turn the power supply on and wait for 10 minutes.  
6) Run Mode: Push MODE button and confirm that only the  
LD1 green light is blinking.

I/O RANGE LABEL  
Blank I/O range labels are included in the product pack-  
age. Write in the configured ranges and put the label on  
the side above the specification label as shown below.  
INPUT & OUTPUT RANGING  
[Example]  
Setting input to 4 – 20mA DC and output to 1 – 5V DC  
1) Run Mode: Confirm that the LD1 green light is blinking.  
2) Input Configuration Mode: Press MODE button for longer  
than 5 seconds until the LD1 red light is ON and the LD2  
red light is blinking.  
3) 0% Input Ranging: Apply the desired minimum input  
level (e.g. 4mA) from the simulator and push DOWN  
button until the LD1 flashes for approx. 2 sec. and then  
turns OFF. When you release the button, the LD1 is  
returned to ON.  
The flashing 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).

OUTPUT  
4) 100% Input Ranging: Apply the desired maximum input  
level (e.g. 20mA) from the simulator and push UP button  
until the LD1 flashes for approx. 2 sec. and then turns  
OFF. When you release the button, the LD1 is returned to  
ON.  
I/O Range Label (included in the product package)  
5) Output Configuration Mode: Push MODE button and  
confirm that the LD3 red light instead of LD2 is blinking.  
6) 0% Output Ranging: Increase or decrease the simulated  
input until the meter shows the desired minimum output  
level (e.g. 1V). Push DOWN button until the LD1 flashes  
for approx. 2 sec. and then turns OFF. When you release  
the button, the LD1 is returned to ON.  
7) 100%OutputRanging:Increaseordecreasethesimulated  
input until the meter shows the desired maximum output  
level (e.g. 5V). Push UP button until the LD1 flashes for  
approx. 2 sec. and then turns OFF. When you release the  
button, the LD1 is returned to ON.  
8) Run Mode: Programming complete, push MODE button  
and confirm that only the LD1 green light is blinking.  
ZERO & SPAN ADJUSTMENTS  
After the transmitter is installed and operational, fine zero  
and span tuning can be performed as explained below. Both  
zero and span are adjustable within ±15%.  
1) Run Mode: Confirm that the LD1 green light is blinking.  
2) Fine Zero Calibration Mode: Press MODE button for 1 or  
2 seconds until the LD1 red light is ON and the LD2 green  
light is blinking.  
3) UseUP(increase)andDOWN(decrease)buttonstoadjust  
the output to 0%.
