In case of unwanted reactions of the door, verify whether the problem is caused by the sensor, the door
controller, or a nearby radar sensor. To do so, activate Service Mode (no safety) and cycle the door open.
Be sure
to exit Service Mode when finished with troubleshooting activities.
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 6 inches between the FLATSCAN SW and radar sensors or use the LZR®-Flatscan
protective cover to avoid unwanted reactions of the door.
