3 Function
Intended use
- Automatic switching of lighting depending on the heat motion and ambient brightness.
- Operation with flush-mounted insert for switching or dimming or 3-wire extension insert to
expand the detection area.
- Ceiling installation on flush-mounted insert.
Product characteristics
- Constant light control in combination with dimmer insert
- 2-point light control in combination with switch insert
- Run-on time and brightness value settable
- Test operation for checking the detection area
- Push-on cover for limiting the detection area
- Expansion of the detection area in combination with 3-wire extension insert
- Manual switch-on and switch-off possible with 2-wire extension insert or installation button
Automatic operation
The presence detector detects heat motions of people, animals and objects.
The light is switched on:
- If someone or something enters the monitored detection area and the brightness is below
the set level. Dimmer inserts first switch to maximum brightness.
- The light remains switched on as long as motions are detected in the detection area and
the brightness is not below the set level.
The light is switched off:
- If no more movement is detected in the detection area and the run-on time has elapsed.
- If the brightness exceeds twice the set value for longer than 10 minutes.
i The minimum switch-off brightness is 400 lux, even if a lower value is set.
The light is switched off in combination with dimmer inserts:
- If no more movement is detected in the detection area and the run-on time has elapsed.
This is done by first dimming the light to minimum brightness and switching it off after
5 minutes.
- If the light has been dimmed to minimum brightness and the brightness exceeds 1.5 times
the set value for longer than 10 minutes.
If the light was switched off because the brightness value was exceeded, the light control
remains active. This means that the light is switched on again as the brightness decreases.
With dimmer inserts, the light is switched on with minimum brightness.
Expanding the detection area
To extend the detection area, the presence detector cover is combined with a 3-wire extension
insert and connected to a main device. The adjusters of the presence detector cover on the 3-
wire extension insert have no function. When motions are detected, the extension transmits a
signal to the main device.
i Do not connect any main devices in parallel.
Behaviour in case of a mains failure
- Less than 0.2 seconds: the old switching position is restored after mains return.
- Longer than 0.2 seconds: a self-test is performed after mains return. This takes approx.
30 seconds. The light is switched on during the self-test; operation via extensions is not
possible.
4 Operation
Switching on the light
A 2-wire extension or an installation button is connected.
o Press button for less than 0.4 seconds.

i If motions are detected, the light remains on after the 2 minutes have elapsed. The run-on
time is set to the time specified on the adjuster.
i If the time adjuster is set to test, then the light remains switched on for approx. 1 seconds,
even if the button is pressed for longer.
Switch light on with minimum brightness
Presence detector cover is combined with a dimmer insert.
A 2-wire extension is connected.
Light is switched off
o Press button at bottom for longer than 0.4 seconds.
Light is switched on to minimum brightness and maintains it as long as motions are
detected.
Switching the light off
It is possible to switch the automatic function off in a targeted fashion, e.g. in order to darken a
room.
A 2-wire extension or an installation button is connected.
Light is switched on.
o Press button for less than 0.4 seconds.
The light is switched off for 3 minutes. Each detected motion extends the time by
3 minutes. After the 3 minutes have elapsed the presence detector is in automatic mode
again. During these 3 minutes the light can only be switched on again using the 2-wire
extension or the the installation button.
Switching off the brightness evaluation
The brightness evaluation can be switched off if the brightness is perceived as too dark after the
light is switched off.
A 2-wire extension or an installation button is connected.
The presence detector has switched the light off due to adequate extraneous light, e.g. daylight.
o Press the installation button within 1 minutes after switch-off.
The light is switched on. The light remains switched on as long as the presence detector
detects motions. The brightness is not evaluated.
i After the run-on time has elapsed, the presence detector switches off and is in automatic
mode once again.
Changing brightness value temporarily
The light can be dimmed using the 2-wire extension. The set value is retained until the
presence detector cover switches off. The next time it is switched on, constant light control is
performed again using the set brightness value.
Presence detector cover is combined with a dimmer insert.
A 2-wire extension is connected.
Light is switched on.
o Press button at top or bottom for longer than 0.4 seconds.
Light becomes brighter or dimmer as far as the respective limit value.

5 Information for electrically skilled persons
5.1 Fitting and electrical connection
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before carrying out work on the device or load, disengage all the
corresponding circuit breakers. Cover up live parts in the working environment.
Selecting the installation location
Figure 2
The presence detector is installed on the ceiling, and monitors the surface under it (Figure 2).
The presence detector has a detection area of 360°. Die PIR sensor system operates with 6
detection levels and 80 lenses.
Figure 3: Detection field
The range is approx. 5 m in diameter at table height, e.g. approx. 80 cm. At floor level the range
diameter is approx. 8 m (Figure 3).

BLC
BLC presence detector with constant light control

These data are applicable for installation on the ceiling at an installation height of 2.5 m.
At installation heights greater than 2.5 m the detection area becomes larger, while at the same
time the detection density and sensitivity are reduced.
i If necessary, the detection area can be limited using the push-on cover (see Limiting the
detection area).
o Select a vibration-free installation location; vibrations can lead to unwanted switching.
o Avoid interference sources in the detection area. Interference sources, e.g. heaters,
ventilation, air conditioners, and cooling light bulbs can lead to unwanted switching.
Fitting the presence detector cover
o Align the presence detector so that the brightness sensor is on the side away from the
windows. This reduces the effects of scattered light.
o Connect flush-mounted insert properly and mount in accordance with the desired
orientation of the presence detector (see instructions for flush-mounted insert).
o Fit presence detector cover on flush-mounted insert.
5.2 Commissioning
Testing the detection area
The presence detector is mounted and connected properly.
o Pull off decor ring (3).
o Set lux adjuster to3(Figure 1).
The presence detector operates independently of the brightness.
o Turn time adjuster to test(Figure 1).
The presence detector switches on for approx. 1 second when there is motion.
o Pace off the detection area, paying attention to reliable detection and interference sources.
o Limit detection area if necessary using the push-on cover.
o Attach decor ring (3).
Limiting the detection area
Figure 4: Push-on cover
The push-on cover can be used to limit the detection area, e.g. in order to mask out
interference sources.

Cover size Detection area on the floor
Complete cover Ø approx 2.2 m
Area I cut out Ø approx 4 m
Areas I + II cut out Ø approx 6 m
Without cover Ø approx 8 m
All data are applicable for an installation height of 2.5 m
o Pull off push-on cover
o Using scissors, cut out push-on cover along the marked lines as required.
o Push on push-on cover
Setting the brightness value in combination with dimmer insert
o Pull off decor ring (3).
o Turn adjuster (7) time to 30 min.
o Turn lux adjuster to 3.
LED (5) is off.
i Do not place brightness sensor (1) in shadow, because otherwise correct brightness
measurement will not be possible. The measured brightness value consists of the reflected
artificial light and daylight, and depends on the reflective characteristics of the surface
under the presence detector.
i If the presence detector is switched on via an extension, the lux adjuster is not evaluated.
o Switch on presence detector via motion in the detection area.
The brightness value should be adjusted in several steps, because the presence detector
requires some time to adjust itself to the changed value.
o Turn lux adjuster (7) in the 2 direction until the desired brightness value is reached.
Presence detector is set to the current brightness.
i If lux adjuster is on 0, the presence detector only switches on through operation of an
extension. In this case the switch-off brightness is 400 lux.
o Attach decor ring (3).
Calibrating the brightness value in combination with switch insert
Brightness calibration is necessary to prevent light oscillations from occurring. A light oscillation
occurs when the presence detector switches off again due to the lighting that has been
switched on (brightness value exceeded). The brightness calibration is performed in the lighting
situation that is required as workplace brightness. The lighting controlled by the presence
detector is switched on. Avoid extraneous light, e.g. from daylight and other lighting. Various
lamps, e.g. fluorescent lamps, require some time to reach full brightness. Therefore note the
run-in phase of the lamp. The LED (5) can be used as an adjustment aid.
Meaning of the LED with the load switched off
LED off Monitored surface is too dark, load switches
on when motion detected.
LED on or LED flashes Monitored surface is bright enough, load
remains off when motion detected.
Meaning of the LED with the load switched on
LED off Monitored surface is too dark, load remains
switched on when motion detected. When no
motion is detected, it is switched off after the
run-on time elapses.

LED on Monitored surface is bright enough due to
lighting that is switched on, load remains
switched on when motion detected. When no
motion is detected, it is switched off after the
run-on time elapses.
LED flashes Monitored surface is very bright due to lighting
that is switched on or extraneous light, load
switches off after approx. 10 minutes, even if
the run-on time is set longer or if motion is
detected.
o Pull off decor ring (3).
o Turn time adjuster (7) to 30 min.
o Turn lux adjuster to 3.
LED (5) is off.
i Do not place brightness sensor (1) in shadow, because otherwise correct brightness
measurement will not be possible. The measured brightness value consists of the reflected
artificial light and daylight, and depends on the reflective characteristics of the surface
under the presence detector.
o Switch on presence detector via motion in the detection area.
o Turn lux adjuster (7) in 2 direction until LED (5) lights up.
Presence detector is set to the current brightness.
i If lux adjuster is on 0, the presence detector only switches on through operation of an
extension. In this case the switch-off brightness is 400 lux.
o Attach decor ring (3).
Setting the run-on time
The fewer the motions expected in the monitored area, the longer the run-on time setting should
be. This reduces the probability that the presence detector will switch off even though people
are present. Use 10 minutes as the default setting value.
o Pull off decor ring (3).
o Turn time adjuster (6) in the appropriate direction.
The presence detector is ready for operation
o Attach decor ring (3).
