SERVICE MODE

TROUBLESHOOTING

In case of unwanted reactions of the door, verify whether the problem is caused by the sensor, the door controller or
a radar sensor in proximity. 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 a radar sensor.
Keep a minimum distance of 15 cm between the FLATSCAN modules and radar sensors or use the LZR ® -FLATSCAN
Protective cover to avoid unwanted reactions of the door.
The RED, GREEN or BLUE
LED is ON sporadically
or permanently and the
door does not react
as expected.
The sensor does not
react at power-on.
The sensor does not
react when powered.
Opening function does
not react at power on.
It is not possible to
adjust a setting by
remote control.
The remote control does
not react.

The service mode deactivates the door safety during 15 minutes and can be
useful during an installation, a mechanical teach-in of the door or maintenance
work.
To enter the service mode, push on the button for > 3 seconds.
When the sensor is in service mode, the LED is off.
To exit the service mode, push again for > 3 seconds.
The service mode is deactivated automatically when launching a teach-in.
Bad teach-in.
Unwanted detections
(due to environment or
external conditions).
Inverted power supply.
Faulty cable.
Faulty sensor.
Test error.
The opening function is deac-
tivated during 30 seconds at
power on.
Wrong DIP-switch position.
The sensor is protected by a
password.
Launch a new teach-in (closed door).
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 (closed door).
4
Switch DIP 2 to off (critical environment).
Check wiring (green +, brown -).
Replace cable.
Replace sensor.
Check voltage between red and blue wires.
Press the push button during at least 3 seconds
to exit the service mode.
Wait 30 seconds.
Adjust the required DIP-switches to ON.
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.
