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 setup actions
in each step of Calibration Modes. Please read the following explanations referring to "Calibration Flow Chart".
PREPARATION (e.g. M3LV-R4/A)
■
1) Mount the DIP-SW-configured M3LV on to a DIN rail.
2) Connect the M3LV 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.

When you set 0% or 100% input/output ranges,
keep pressing UP or DOWN button until the
LD1 blinks for approx. 2 seconds and turns off,
which indicates the setup is complete.
If the LED does not change, the entered level may
be inappropriate: e.g. out of usable range.
* For the model M3LV-x/A, the green LED is blinking.
For the model M3LV-x/B, the green LED turns on.
