*1. Connect the Sensor to an G9SP to use it as a safety device or as part of a safety system.
*2. Depending on the wiring, this may turn ON when light is interrupted.
       For your safety, be sure to connect the pink receiver wire (mode selection input) to 24 VDC to turn ON when light is
       incident.
