One potentiometer is provided
in order to determine the
brightness setting (lux value) in
addition to the switch-off delay
(time setting) respectively.
Using the switch-off delay
(4–15 minutes), the period is
determined during which the
light remains switched ON after
recording the last movement.
With each further detection of
movement, the set overshoot
time begins again until motion
is no longer detected or the
surrounding brightness reaches
the adjusted brightness setting.
Only BLS / BLS T:
Pulse mode: If the controller is
set to “ ”, the device is in
pulse mode, i.e. the output is
switched ON for approx. 2 sec.
(e.g. for an staircase lighting
timer). Afterwards, the sensor
does not react to movement for
approx. 8 sec.
The brightness setting to be
set on the sensor (20–1300 lux)
determines the daylight-de-
pendent switching behaviour
of the sensor. On operation of
the control, the sensor switch-
es the lighting OFF in any
case. On completion of adjust-
ment, the following applies:
if the amount of daylight is
below the set brightness set-
ting, the lighting is switched
ON; if the amount of daylight
is above the brightness set-
ting, the lighting is switched
OFF – even in case of move-
ment within the detection
zone.
Thebrightness setting to be
set on the sensor (100–1300
lux) determines the total light
level in the room. If the sur-
rounding brightness lies below
the set theoretical value on
motion detection, the light
sensor detects the difference
and dims the lighting until the
desired theoretical value is
achieved. Changes in the
amount of daylight are con-
stantly detected by the light
sensor and are adjusted such
that with occupancy, a con-
stant brightness prevails in the
room.
Hint: The brightness setting is
best adjusted in test mode
(control for switch-off delay
set to "Test"), since the light
control (dimming) follows all
changes in brightness in this
case.

Technical specifications
BLS / BLS T
The test mode is suitable for
verifying operational status
and for specifically adjusting
the detection zone (also see
Reach setting section).
In order to activate test
mode, the control for the light
threshold is to be turned to
the "Test" position. In test
mode, the sensor switches on
the lighting with an overshoot
time of 5 seconds, regardless
of the surrounding brightness.
Note: When the sensor
switches the lighting off, a
short waiting time of approx.
4 sec. must be observed be-
fore the sensor can react to
movement again.
In order to activate test mode,
the control for the time setting
is to be turned to the "Test"
position. During test mode, the
light control (dimming) directly
follows all changes in bright-
ness (e. g. hold a hand in front
of the sensor lens). The correct-
ness of the wiring can be rapid-
ly checked in this manner.
If the sensor does not dim the
lighting in accordance with the
changes in brightness, the
wiring has not been performed
correctly.
When test mode is quitted, the
dimming behaviour of the sen-
sor is optimally readjusted to
human perception.
