SYMPTOMS PROBABLE CAUSES CORRECTIVE ACTION
The door will not open and no red LED
lights up.
The sensor power is off. Check the wiring and the power supply.
The door opens and closes constantly. The sensor "sees" the door moving. Increase the tilt angle and/or reduce the sensitivity.
When closing, the door creates
vibrations picked up by the sensor.
Make sure that the sensor is correctly fixed.
Increase the immunity (dip switch 4: ON).
Reduce the sensitivity.
The door will not close.
Red LED is OFF.
ON-OFF switch at door control is in
wrong position or faulty.
Improper output configuration.
Make sure that the ON-OFF switch for the door is in the ON or
AUTOMATIC position. Check the output configuration setting
on each sensor connected to the door operator.
It rains and the sensor detects for no
apparent reason.
The sensor detects the motion of the
rain drops.
Use the PASM24C accessory.
