Setting of short-time duty
Within the scope of a special operating mode, the Comfort
motion detector top can also be set to short-time duty. The short-
time duty operates irrespective of the current brightness level
and can be used, e.g. for controlling a bell.
For this mode the delay time controller is set to the shortest
time (symbol similar to
Ω
).
If a motion is detected, the Comfort motion detector top switches
on for 0.5 s. If the detector continues to detect motions, the light
ing is not switched on again until a locking time of 3 s has
expired.
Setting of the brightness threshold
The brightness threshold is the threshold of the brightness at
which a detected movement releases a switching operation.
The brightness threshold can be set within a range of approx.
0 to 80 lux.
To modify the brightness threshold, the controller must be
turned in the desired direction.
If the controller is set to the "sun" limit stop (> 80 lux), the
Comfort motion detector top wo
rks in day mode and therefore
switches irrespective of the
current brightness level.
Note: if the Comfort motion detector top no longer responds to a
detected motion at the "moon" limit stop (night setting, 0 lux), the
controller must be turned slightly in the direction of the sun.
The comfort motion detector top has a high imm
unity to external
light. For this reason, the Comfort motion detector top
• Does not interpret a brief illumination (e.g. that of a flashlight)
as "brightness threshold exceeded", thus causing it not to
switch in the case of motion, so that the motion detector can-
not be disabled by exposing it briefly to a bright light,
• Does not interpret brief unintentional shadowing (e.g. by a
person) as "brightness threshold fallen below" and does not
switch on in case of motion.
The external light immunity is attained by a time delay.
When brightness turns into darkness, the set brightness thresh-
old must be fallen below for at least 10 s
before detected mo-
tions initiate a switching operation.
The same applies to the changeover from darkness
to bright-
ness. Only if the set brightness threshold has been exceeded by
at least 10 s will detected motions no longer initiate a switching
operation.
Exception: If the Co
mfort motion detector top has just switched
off, the 10 s time delay is no longer active.
Releasing the teach function
By means of the teach function, the current ambient brightness
can be stored as brightness threshold whereas the brightness
threshold set at the controller is no longer evaluated.
To activate the teach function, the Comfort motion detector top
must be
co
mpletely covered briefly (approx. 1 s) at least 3 times,
e.g. using your hand, within a 9-second period.
As soon as the Comfort motion detector top has detected three
light changes, the teach function is activated. This activation is
confirmed
• When the switched on lighting is switched off and subse-
quently switched on for 3 s,
• The switched off lighting is switched on for 3 s.
You then need to step away from the Comfort motion detector
top for at least one minute in order to enable it to correctly mea-
sure and
sto
re the current brightness.
The lighting then switches on for 3 s to confirm that this bright-
ness level has been stored.
The Comfort motion detector top switches to the set operating
mode.
If the brightness threshold set at the controller is to be reacti-
vated, the Comfort motion detector top must be pulled off the
insert and plugged on again.
