Setting the sensitivity
The Comfort motion detector top has an internal algorithm which
carries out an automatic adjustment to the ambient conditions.
This virtually eliminates the possibility of unintended switching
operations.
Under normal circumstances, the controller should be set to
maximum sensitivity.
If, in exceptional cases, it is necessary to determine a different
sensitivity level, this can be done using the controller .
Schematics
Caution: It is not permissible to connect motion detector center
units in parallel.
Extension units
The sensing range of a center unit can be extended by means
of extension units. This can be achieved by combining, for
example, a Comfort motion detector top with a motion detector
extension unit insert and connecting it to the center unit.
Caution:
• Motion detector extension units are not suitable for the direct
switching of loads but just issue brightness-independent
motion signals to the center unit.
• The brightness t
hreshold, the operating mode and the delay
time are set and evaluated at the center unit only.
• The operating mode switch and the controllers for brightness
and delay time of the Comfort motion detector top on the
extension unit have no function.
• If required, the Comfort motion detector top plugged onto the
extension unit can be adjusted over the respective controller
(see the section Programming).
• When combining the Comfort motion detector
top with the mo-
tion detector extension unit insert, please note that after the
lighting has been switched off, there is a locking time of ap-
prox. 3 s before the extension unit can be switched on again.
Mechanical pushbuttons
Using mechanical pushbuttons without a glow lamp (NO con-
tact) and with automatic mode activated, the Comfort motion
detector top can be operated from several sides.
In case of a short operation in the switched off state, the lighting
is switched on irrespective of the current brightness level.
It is not possible to switch off the lighting.
