6.2 Troubleshooting
Light does not switch on despite motion detection and low lighting
Cause 1: Wrong function block active.
Change function block switch-over.
Cause 2: Brightness threshold set is too low.
Increase the brightness threshold with the remote control or parameter setting.
Light switches on despite sufficient ambient lighting
Cause 1: Signal function is active and the device therefore operates independently of the
brightness.
Check programming.
Cause 2: Device operates independently of the brightness.
Adjust the brightness threshold with the remote control.
Adjust parameter setting for brightness threshold.
Light switches off briefly and then on again immediately
Cause 1: Light bulbs in the detection area.
Set the configuration barrier parameter so that cooling light bulbs are not detected.
Cause 2: The brightness threshold set is not reached after switching off. Device switches on
again immediately during motion detection.
Increase brightness threshold.
Light switches off early despite motion detection and low lighting
Cause 1: The set time is too short.
Increase the time with the remote control or parameter setting.
Cause 2: Detection problem, the surface to be monitored is not in the detection area, or
furniture or pillars are in the way.
Check detection field, extend presence detector extension if necessary.
Device responds even without any motion in the detection field
Cause: Interference sources in the detection area or device are set too sensitively.
Limit detection area, remove interference sources.
Adjust sensitivity by one level with adjuster
Sens.
(6) or with remote control.
Reduce sensitivity in parameter setting.
i
The sensitivity should be reduced by 1 to 2 levels in small spaces.
Light does not switch off despite sufficient ambient lighting
Cause 1: Device is set as motion detector and therefore does not evaluate the ambient lighting
after reacting.
Check programming. Set and program device as presence detector.
Cause 2: Brightness threshold set is too high.
Decrease the brightness threshold with the remote control or parameter setting.
Light does not switch on or switches on too late despite motion in the detection field
Cause 1: Device is set for alert operation and does not evaluate the first motion impulse
detected.
Check programming. Set and program device as motion detector.
