Installation; Operation; Function Test - Conrad 55 30 92 Bedienungsanleitung

After switching on the mains voltage, it takes about 30 seconds until the PIR sensor in the
ceiling-mounted motion detector has adjusted itself to the background temperature and is able
to recognise changes in temperature within the detection range.
Detection through glass (e.g. a window) is theoretically not possible.
Connection
Connect the power cables with the
appropriate terminal screws:
L = Phase (brown cable)
N = Neutral wire (blue cable)
A = Switching outlet for connection
of the powered device
Note the imprint on the housing next to
the screw clamps.

Installation

Pay attention to the information in chapter "Preparations for Installation"!
• Fasten the ceiling-mounted motion detector with two
screws and plugs to the room ceiling.
Use screws and plugs that are suitable for the surface.
Pay attention when drilling/tightening the screws
that no power, gas or water pipes are damaged!
Make sure that the mains cables are not pinched
or damaged!
• After confi guring the controls (see next section), mount the
cover ring and lock it by turning clockwise.
• The detection range can be restricted by covering the dif-
fusion panel of the ceiling-mounted motion detector with
opaque adhesive tape.
Controls on the ceiling-mounted motion detector
• Setting the on-time (control dial "TIME")
Using this control knob, you can set the switch-on time for the powered device connected.
Turning the control knob counter clockwise, to the left, shortens the on-time; turning it to the
right lengthens it.
If a new motion is detected during the on-time, the time for the on-time starts again.
• Setting the brightness adjustment (control dial "LUX")
This control knob allows the switching threshold to be set, i.e. the ambient brightness at
which the ceiling-mounted motion detector is activated.
Turning the knob to the left in direction of the moon symbol activates the ceiling-mounted
motion detector only with great darkness, turning it to the right in direction of the sun symbol
activates the motion detector in brighter conditions.

Operation

As already explained in the chapter "Function of the ceiling-mounted motion detector", the
PIR sensor in the ceiling-mounted motion detector responds to temperature changes in the
detection range.
When a temperature change is detected, the relay is activated and switches on the connected
power consumer for the set time. If new motion is detected during the on-time, the on-time
duration starts once again; the consumer stays switched on.
When a temperature change is no longer detected, the connected consumer is switched off.

Function test

If you want to perform a function test after installation, proceed as follows:
• Turn the control knob "TIME" all the way to the left (anticlockwise) towards "-" to select the
shortest switching time.
• Turn the control knob "LUX" all the way to the right (clockwise) towards the sun symbol.
• Cross the detection range. When the PIR sensor detects a temperature variation in the detec-
tion range, the powered device is switched on for a few seconds and then switched off again
(unless there are temperature variations).
Maintenance and Care
The ceiling-mounted motion detector is maintenance-free. For this reason, you should never
open it or take it apart (except for the installation described in this manual). Maintenance or
repairs may only be performed by qualifi ed personnel.
Occasionally, clean the hemispherical diffusion panel on the ceiling-mounted motion detector
from dust or sediments; only use a dry, clean and soft cloth.
Disposal
Dispose of an unserviceable product in accordance with the relevant statutory regu-
lations.
