Using Sensors to Trouble Shoot
• Photo Sensors often get dirty. Make sure they are clean. If they are not clean, debris
may block the signal or provide a false signal.
• Check output voltages of the sensors in the
active
mode. The voltage should effec-
tively equal
0 VDC
• Check the output voltages of the sensors in
inactive
mode.The voltage should effec-
tively equal
24 VDC
The distance from an eye to the door should be in range. Typically the range should be
3/4'' to 7/8'' from the top of all eyes to the door.
