This function stops light emission of an emitter. It is available for checking if the F3SN can
show the correct OSSD (Output Signal Switching Device) outputs state, and so on.
[Directions for use]
Applying a voltage of 24VDC (for PNP type) or 0 V (for NPN type) to the test input line of an
emitter makes the emitter stop emitting.
