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 sensor window. Device can be damaged.
The device is not suitable for use as a burglar alarm or other alarm.
These instructions are an integral part of the product, and must remain with the end
customer.

- Follow-up time and brightness value settable
- Test operation for checking the detection area
- Range can be set in three levels
- Parallel connection of multiple motion detectors possible
- Manual switch-on possible with installation button, NC contact
Automatic operation
The controller detects heat motions of people, animals and objects.
- The light is switched on if a person enters the 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. 3 seconds after switch-off.
2: Detection area, motion detector
4 Operation
Switching the light on manually
Optional installation button, NC contact is installed (connect the motion detector).
o Press the installation button for at least 1 second.
Light is switched on independently of the brightness for the set follow-up time.
When motions are detected, the delay time is restarted.
5 Information for electrically skilled persons
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.
3: Installation laterally to the direction of movement
Selecting the installation location
At an installation height of 2.4 m ( 2), the optimum range of the motion detector is achieved
transversely to the direction of movement ( 3).
The range is reduced in the case of:
- The land slopes upwards away from the motion detector
- Internal housing in middle or lower lock ( 6)
- Low temperature difference
- Installation height less than 2.4 m
- Effects of weather, e.g. rain, fog or snow
The range is increased in the case of:
- The land slopes downwards away from the motion detector
- High temperature difference
- Installation height greater than 2.4 m
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, or cooling light bulbs can lead to unwanted switching.
o Take direction of motion into account.
o Determine installation height.
i To achieve a rapid response from the motion detector on leaving the building, install the
device at a height of less than 2.4 m, centrally above the door.
Installing the motion detector
o Slacken central screw (3) ( 1).
o Remove the housing cover.

4: Rear housing panel and installation frame
i To prevent the ingress of moisture, we recommend inserting the cables from below (10).
o When the cables enter below, use an installation frame (9). Insert the rear housing panel
(7) into the installation frame.
o Do not use an installation frame for surface cable entry from the side or from above, but
instead penetrate one of the the thinner areas of the rear housing panel.
i Do not remove the water-permeable closure of the condensation water hole (8).
o Run the connection cable into the connection compartment through a rubber sleeve (4).
o Fasten the rear housing panel on the installation location with two screws (6) in such a way
that the condensation water hole is at the bottom.
Configuring the motion detector
On the rear side of the housing cover of the motion detector, there is one adjuster each for the
follow-up time (11) and the brightness threshold (12) ( 5).
5: Setting the follow-up time and the brightness threshold
The range of the motion detector can be set in three stages by sliding the internal housing (13)
( 6).
82523522 19.05.2011 4/8
Observer 70
6: Setting the range
o Set the required follow-up time using the adjuster (11).
o Set the required brightness threshold with the adjuster (12). The 3 icon stands for Day
mode, i.e. switching independent of brightness, and the 2 icon for minimum brightness.
i Should the device need to switch at the start of twilight, then set the adjuster (12) as shown
in ( 5).
o Set the range by sliding the internal housing ( 6).
Top lock (14) Maximum range
Centre lock (14) Medium range
Bottom lock (14) Minimum range
o Measure the detection area by walking it. To do this, switch the motion detector to test
mode. Set the follow-up time to 10 seconds and the brightness value to 3.
Connecting the controller
7: Stripping the connection cable
The connection cables are equipped with screwless terminals. For secure contacting, connect
only single-wire cables with a cross-section of maximum 2.5 mm². Observe the stripping lengths
for external cable jacketing and basic insulation ( 7).
blue, BU N, neutral conductor
brown, BN 8 Lamp cable
black, BK L, conductor
o Insert the screwless terminals for fixing into the holders (5) of the housing cover ( 4).

8: Motion detector connection diagram
o Connect controller and optional installation button T, NC contact, according to connection
diagram ( 8).
o If multiple motion detectors are to switch a shared load, connect the motion detectors in
parallel.
i Parallel switching of multiple motion detectors does not increase maximum connected load.
9: Connection diagram, switching off motion detectors
The motion detector can be switched off using installation switch S1 or S2 ( 9). Switching
installation switch S1 on again triggers switch-on for the follow-up time. Installation S2 does not
do this.

10: Connection diagram, Automatic manual mode
Installation switch S1 ( 10) can be used to switch Automatic mode on and off. Installation switch
S2 can be used to switch Manual mode on and off.
o Lock the housing cover into the bottom of the rear housing panel, push the top down and
screw it tight with the central screw (3).
