. Troubleshooting
Fault Cause
Lighting does not switch on
or switches off in case of
presence and darkness Lux value setting is too low; Detector is in semi-automa-
tic mode; Lighting was switched off manually; Person is
outside the detection range; Detection is disturbed by
obstacle(s); Set switch-off delay setting is too short
With persons present, the
lighting is on although the
brightness is sufficient
Lux value setting is too high; The lighting has been
switched on manually with clic recently (wait for 30
min); Detector is in test mode
Lighting does not switch off
or switches on spontane-
ously in case of absence Wait until the switch-off delay time has elapsed (self-
learning effect); Disturbing heat sources within the
detection range (heaters, incandescent lamp/halogen
lamp, moving objects (e.g. curtains due to open
windows); Load (el. starter devices, relay) has no
interference suppression
Lighting keeps switching
on and off during the
service phase
Too much artificial light is falling on the detector. Incre-
ase lux value or reposition the detector.
Push-button does not work Device is still in start-up phase or an illuminated push-
button without PEN conductor connection is used;
Push-button is not connected to the master
Lighting cannot be switched
off with the push-button DIP-switch in „corridor“ position
Device does not respond Short circuit/ multiple phases connected in parallel!
Disconnect detector from mains for 5 min. (thermal
protection switch).
Error blinking (4x per sec.) Failure during self test. Device not working!
