Photoelectric sensor wiring
Our photoelectric sensors don't work. The lights light up, and change when something is moved underneath the sensors, but they don't send signal, to track the line. Right now we have them wired so that brown and blue are power from the PDB, and white is plugged in to the DSC, and black is plugged in to nothing. Where should white be plugged in on the Digital I/O of the DSC, pin 1, 2, or 3? Is this wired correctly?
