24 Troubleshooting
Fault Cause Remedy
Lighting system on after
the detector is
connected. Both outputs are closed for 90
s after the detector has been
connected (test phase) Wait for 90 s. The device then
responds immediately to changes in
brightness for 10 minutes.
The detector does not
switch off after 90 s The detector may respond
more slowly in accordance
with the switch-off delay time Wait until the switch-off delay time
has elapsed
Immediate response to
change in brightness The device is in service phase
(10 minutes)
This phase is used to adjust
the brightness setting Test: "blind" with torch –> lights off.
Darken (e.g. with blinds) –> lights on.
After the service phase, the system
response to a change in brightness is
delayed to prevent sudden activation /
deactivation.
Lights never switched on,
despite presence of
persons and little daylight 1. Lux value too low.
2. Detection zone does not
cover the entire room Vision
may be impaired.
3. No sensitivity setting
4. Lamp supply line
interrupted by switch. 1. Increase Lux value.
2. Change mounting location or
remove obstacles in detection range.
3. Sensor element may be defective.
4. Set switch to "ON".
Lights flash constantly 1. Incandescent lamps trig-
gered by ECO-IR.
2. Direct illumination of detec- 1. See section 2.3, set Lux value to
„on“ or replace incandescent lamps
with FL/PL lamps.
2. See section 2.3, check arrange-

tor from fluorescent lamps too
high. ment of detector with regard to lamps.
Lights on continuously /
detector switches without
reason
1. Lux value too high.
2. Other movements have
been registered.
3. External contactor or relay
triggered
4. Several detectors con-
nected in parallel
5. "Self-learning effect" 1. Decrease Lux value.
2. Switch off devices with instant heat
emission (e.g. heater, halogen spots,
incandescent lamps), close open
doors and windows, are other moving
objects (curtains, suspended signs) or
domestic animals present?
3. Inductive loads must be fitted with
suitable spark extinguishers by quali-
fied technicians (e.g. RC element).
4. Check Lux setting on detectors
5. Remove ECO-IR and connect it
again, repeat initialization.
Lights extinguish despite
presence of persons Minimum switch-off delay time
too low Check recommended settings,
increase switch-off delay time.
Lights extinguish too late
after the room is vacated Minimum switch-off delay time
too high Reduce switch-off delay time.
See section 2.5 in these instructions
–> self-learning adjustment of switch-
off delay time.
Detection zone is smaller
than specified 1. Objects in visibility range
2. Detector positioned
incorrectly
