1 Safety instructions
Electrical equipment may only be installed and fitted by electrically skilled persons.
Failure to observe the instructions may cause damage to the device and result in fire and
other hazards.
Danger of electric shock. Device is not suitable for disconnection from supply voltage.
Danger of electric shock. Always disconnect before carrying out work on the devise or
load. At the same time, take into account all circuit breakers that supply dangerous
voltage to the device or load.
Do not press on the lens. Device can be damaged.
Do not open the sensor head, because close sealing is not possible. Foreign bodies and
spray water can penetrate and damage the device.

3 Function
Intended use
- Automatic switching of lighting depending on the heat motion and ambient brightness.
- Surface-mounting in indoor and outdoor areas
Product characteristics
- Variable installation position
- Protected against spray water
- Follow-up time, sensitivity and brightness value settable
- Test operation for checking the detection area
- Sensor head adjustable in 3 axes
- Screens for limiting the detection area
- 18 detection zones in 3 levels
- Parallel connection of multiple controllers possible
- Manual switch-on possible with installation button
Automatic operation
The controller detects heat motions of people, animals and objects.
- The light is switched on if a person enters the monitored detection area and the brightness
is below the set threshold.
- The light is switched off if no more movement is detected in the detection area and the
follow-up time has elapsed.
In order to avoid light oscillations due to the cooling of a bulb, the controller does not evaluate
any signals for approx. 2 seconds after switch-off.
4 Operation
Switching the light on manually
Optional push-button is installed.
o Press push-button briefly.
Light is switched on independently of the brightness for the set follow-up time.
When motions are detected, the follow-up time is restarted.
Configuring the controller
The controller has one adjuster each for the brightness threshold, the follow-up time and the
operating mode.

(7) Adjuster for brightness threshold, LUX
(8) Adjuster for operating mode, TEST, ON
(9) Adjuster for follow-up time, TIME
Switch on test operation
In test operation the motion detector operates independently of the brightness. The follow-up
time is approx. 1 second. The motion detector switches on cyclically as long as there is
movement in the detection area.
o Turn adjuster for operating mode (8) to TEST position ( 2).
i The adjusters TIME and LUX have no function in test operation.
Switching on automatic mode
o Turn adjuster for operating mode (8) to ON position ( 2).
Setting the brightness threshold
Only when the brightness drops below the threshold will the light be switched on when there is
motion in the detection area. The brightness threshold is steplessly adjustable in a range from
approx. 5 to 300 lux.
o Turn adjuster LUX (7) to the appropriate position ( 2).
Position Function
3 switches independently of the brightness
300 lux switches when there are heavy clouds or
towards the evening
10 lux switches at twilight
5 lux switches upon darkness
Set follow-up time
The light is switched on for this time The follow-up time is set in a range from approx.
12 seconds to 12 minutes.
o Turn adjuster TIME (9) to the appropriate position ( 2).
Heat radiation too high.
Destruction of the sensors.
Align the device so that no direct sunshine hits the sensor window.
Do not place the device in the sun.

3: Aligning the sensor head
Aligning the sensor head
For optimal alignment of the detection area the sensor head can be adjusted in three axes.
o Slacken central screw (6) somewhat ( 3).
o Slew the sensor head. The scale (10) serves as an aid to orientation ( 3).
o Tighten central screw.
o Slacken manual knob (5) ( 3).
o Incline the sensor head (3).
i If the heavy marks of the scale (11) are aligned with each other, the inclination is
approx. 14 °. ( 3). The farther the sensor head is inclined, the shorter is the range.
o Tighten manual knob (5).
o Turn the sensor head (3) ( 3). The adjustment is detented; each detent corresponds to
approx. 10 °.
Limiting the detection area to the side
4: Detection area with cover plate A
82508412 19.05.2011 4/10
Observer 110

The detection area of the motion sensor can be limited to the side using the included cover
plate A.
o Fit cover plate A( 4).
Reducing the detection area to one level
5: Detection area with cover plate B
Cover plate B masks out the two lower detection levels ( 5).
o Fit cover plate B.
5 Information for qualified electricians
5.1 Fitting and electrical connection
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.
Heat radiation too high.
Destruction of the sensors.
Align the device so that no direct sunshine hits the sensor window.
Do not place the device in the sun.

6: Direction of motion
Selecting the installation location
o Select a vibration-free installation location; vibrations can lead to unwanted switching.
o Avoid interference sources. Interference sources, e.g. heaters, ventilation, air conditioners,
and cooling light bulbs can lead to unwanted switching.
o Take direction of motion into account.
i Motions that are transverse to the motion detector, direction of motion I can be detected
more easily than motions towards or away from the motion detector, direction of motion II
( 6)
o Determine installation height ( 6) III.
i The effects of weather, e.g. rain, fog or snow can reduce the range.

Set brightness threshold using adjuster LUX( 4. Operation).
Detection area is limited.
Align sensor head or adapt cover plate ( 4. Operation).
Controller switches on, even though it is bright enough even without lighting.
Controller is in test operation
Switch off test operation by turning middle adjuster to ON.
Adjuster LUX is at the left-hand end stop, the motion detector switches independently of the
brightness.
Set brightness threshold using adjuster LUX( 4. Operation).
Controller switches on without detected motion
Interference sources in the detection area, e.g. ventilation, cooling light bulbs, trees and
bushes.
Limit the detection area by aligning the sensor head or fitting a cover plate ( 4. Operation).
Controller switches off despite motion
Detection area is limited.
Align sensor head or adapt cover plate ( 4. Operation).
Controller does not switch off after the set follow-up time has elapsed
Controller detects motions constantly. Pay attention to interference sources, e.g. ventilation,
cooling light bulbs, trees and bushes in the detection area.
Limit the detection area by aligning the sensor head or fitting a cover plate ( 4. Operation).
6.3 Warranty
The warranty is provided in accordance with statutory requirements via the specialist trade.
