Troubleshooting Photo Detectors

979-2

Troubleshooting Photo Detectors

Another cause of improper machine operation is a faulty or dirty photo detector.
There are two types of photo detectors, Through Beams and Photo Eyes.

•

Through Beam Detectors

consist of an emitter and detector. The emitter sends a light beam that is

sensed by the detector. The detector then sends 0VDC to the PLC. If the beam is broken the detector
sends 24VDC to the PLC.

•

Photo Eye Detectors

contain both emitter and receiver. If an object is within the Photo Eye’s sensing

field light from the emitter is reflected from the object back to the receiver. The Photo Eye then sends
24VDC to PLC. If no object is sensed the Photo Eye sends a 0VDC to the PLC.

If the photo detector is dirty, it will falsely sense the presence of a door, or other obstruction, and stop
the machine operation. If a suspected Photo Detector is clean check for the proper DC Voltage.
