Recessed-mounted motion detector LBU 1237 (Triac), recessed-mounted motion detector LBU 1244 (relay)
Function
The 195° recessed-mounted motion detector has been designed for
wall mounting and is installed in a recessed-mounted box instead
of a conventional light switch. The motion detector functions using
passive infrared technology (PIR). The device has an in-built PIR sensor
that detects moving heat sources within a fi eld of detection of 195°.
The switching times and the twilight feature are infi nitely variable.
Safety instructions
This device must be installed by a technician in accordance
with the applicable regulations. The electrical power supply
must be switched off throughout the entire installation process.
To guarantee this, the circuit protection must be switched off .
Please check that the connection cable is disconnected!
Under no circumstances does the warranty cover damage resulting
from failure to observe these instructions. Nor do we accept liability
for any indirect damage. Similarly, we can accept no liability for any
material damage or bodily injury caused by mishandling or failure
to observe the safety instructions. No warranty claim may be made
in these cases. In addition, for safety and compliance reasons,
you are not authorised to dismantle or alter the device in any way.
Mounting position
The 195° recessed-mounted motion detector reacts to sources
of heat. To prevent switching errors, ensure that the device is not
installed above heaters or exposed to direct sunlight (Fig. B).
To ensure optimum device operation, please note the following:
larger range smaller range
Installation height > 120 cm < 80 cm
Ambient temperature < 18°C > 18°C

Installation
Remove the frame and the sensor. Now, connect up the device
as shown in the wiring diagram (Fig. A), taking care to choose the
right diagram for the model you are using (LBU 1237 or LBU 1244).
Place the supply unit in the recessed-mounted box and tighten the
two fastening claws on the left and right (Fig. C2). Now attach the
sensor section, screw it to the supply unit and replace the cover
frame. Finally, switch the circuit protection on.
Settings
To enter test mode, adjust the Meter, Time and Lux controllers to
the desired settings as shown in (Fig. D).
You can use the slide switch (Fig. E1) to choose one of the following
settings:
0 = OFF: Always move the switch to this position when replacing
the illuminant.
A = automatic mode: The motion detector switches on the light
when it detects movement and then turns it off again after the
preset length of time has elapsed (provided that the detector has
not detected any further movement).
1 = continuous light mode:
Use the enclosed masking tape (Fig. F) to shield specifi c fi elds of
detection.

Recycling instructions
Do not dispose of this device with unsorted household waste. Owners of old devices are required by law to dispose of this
device properly. Contact your town council for further information.
Troubleshooting - practical advice
Fault Cause
Motion detector responds too late • head-on movement
Maximum range is not reached • Motion detector is mounted too low
• Diff erence between the ambient temperature
and the source of heat is negligible
Lamp is permanently lit or light is switched • Constant warm movements; the motion detector has been installed above a source of heat (e.g. a
on when not needed heating device) or has been exposed to direct/indirect rays of sunlight
Light does not switch on • Faulty fuse
• Observe minimum load of 40 watts
