Malfunction
Cause
Remedy
No power at the sensor
■
Fuse has tripped, not switched
ON, break in DALI wiring
■
Short circuit
■
Activate, change fuse, turn ON
mains switch, check DALI wiring
with voltage tester
■
Check connections
Light level not being
communicated
■
Break in wiring
■
DALI power supply faulty
■
Check cable
Sensor sending motion
detection signal when it
should not
■
There is interference,
e.g. fan, air-conditioning system
or other source of heat,
in the detection zone
■
Animals moving in detection zone
■
Wind is moving paper or plants in
the detection zone
■
Sunlight is shining on the lens
■
Sudden temperature change
due to air expelled from fans,
open windows, air-conditioning
systems or other sources of heat
■
Sensor near Wi-Fi or other wire-
less communication source
■
Adjust detection zone or fit
shrouds, increase distance
■
Adjust zone or fit shrouds
■
Change detection zone
■
Mount sensor in a protected
place or change zone
■
Adjust detection zone or install
in a different place
■
Install at least 2 m away from the
