Setting Output Operation Values
The output operation values can be set using the potentiometer for
adjustment inside the translucent cover.

Setting Method
1.
Set the input signal, hysteresis, contact operation (delay time),
and contact drive method using the DIP switch.
2.
Mount the Unit to DIN rail and wire it.
