. Troubleshooting

Fault
LED blinks fast
Lighting on after
the detector is
connected.
Immediate re-
sponse to change
in brightness
Lights never
switched on,
despite presence
of persons and
little daylight
Lights flash
constantly
(«blinking»)
Lights on conti-
nuously / detector
switches without
reason
Lights extinguish
despite presence
of persons
Detection zone
is smaller than
specified

Cause
No or wrong application
Both outputs are closed for 90
s after the detector has been
connected (test phase)
The device is in service phase
(10 min.). This phase is used to
adjust the brightness setting
1. Lux value too low.
2. Detection zone does not
cover the entire room. Vision
may be impaired.
1. Halogen or incandescent
lamps triggered by ECO-IR.
2. Direct illumination from
fluorescent lamps too high.
1. Lux value too high.
2. Other movements have
been registered.
3. Several detectors connected
in parallel
Minimum switch-off delay time
too low
1. Objects in visibility range
2. Detector positioned incor-
rectly
Remedy
Program correct application
Wait for 90 s. The device then
responds immediately to changes in
brightness for 10 minutes.
After the service phase, the re-
sponse to a change in brightness is
delayed to prevent sudden switching.
1. Increase Lux value.
2. Change mounting location or
remove obstacles in detection range.
1. Set Lux value to „on" or replace in-
candescent lamps with FL/PL lamps.
2. check arrangement of detector
with regard to lamps.
1. Decrease Lux value.
2. Devices with instant heat emission
(e.g. heater), moving objects (curta-
ins, etc.) or domestic animals?
3. Check Lux setting on detectors
Check recommended settings, incre-
ase switch-off delay time.
1. Remove obstacles, replace detector
2. Check detection range
