Connection example

Basic wiring: Min. operation only

This is the general configuration using one set of the emitter and receiver facing each other. The control outputs (OSSD 1 / OSSD 2) turn OFF if the light is interrupted, while they automatically turn ON if receive the light.
The auxiliary output is used to invalid the external device monitoring function. The auxiliary output cannot be connected to external devices.
