TROUBLESHOOTING
In case of unwanted reactions of the door, verify whether the problem is caused by the sensor, or the door controller.
To do so, activate the service mode (no safety) and launch a door cycle.
If the door cycle is completed successfully, check the sensor. If not, verify the door controller, the wiring or other sensor.
The RED or GREEN LED
is ON sporadically or
permanently and the door
does not react
as expected.
Bad teach-in
Launch a new teach-in.
Unwanted detections
(due to environment or
external conditions)
1
Make sure the flexible cable does not cause
detections.
2
Verify if the laser window is dirty and clean it with
compressed air. Then wipe it carefully with a damp
and clean microfibre cloth if necessary.
(attention: the surface of the laser window is delicate)
3
Launch a new teach-in.
4
Switch DIP 2 to off (critical environment).
The sensor does not react
at power-on.
Inverted power supply
Check wiring (green +, brown -).
Faulty cable
Replace cable
Faulty sensor
Replace sensor
The sensor does not react
when powered.
Test error
Check voltage between red and blue wires.
The service moded is activated
Press the push button during at least 3 seconds
to exit the service mode.
It is not possible to
adjust a setting by remote
control.
Wrong DIP-switch position.
Adjust the required DIP-switches to ON.
The remote control does
not react.
The sensor is protected by a
password.
Enter the right password. If you forgot the code, cut
and restore the power supply to access the sensor
without entering a password during 1 minute.
