For backlight function model, the input terminals are no.
, and the GND terminal is no. .
※
AC type proximity sensor cannot be used as the source
of count input signals.
※
Input terminal(

Input from AC type proximity sensor
In case of free voltage input type, do not connect AC proximity sensors instead of a switch as shown in the gure 1.
It may cause malfunction due to sensor's leakage current. Connect a relay as shown in the gure 2.
