Installing The Display; Connection - Conrad Electronic 85 51 49 Notice D'emploi

Installing the display

The core of the parking aid is the acoustic or optic display with integrated warning buzzer.
The displays are attached on the installed adhesive pad. For this purpose, pull the protective paper off
the pad.
When selecting the installation site, make sure that the display is not in the direct visibility
range of the driver or in safety-relevant areas (airbags, etc.).
The surface to which it is attached must be absolutely clean and grease-free. Do not
attach the pad below 5 °C, otherwise the pad will not stick properly.

Connection

After installation of all components, you have to connect the display cables and the voltage supply.
Connect all cables as depicted in the connection scheme in „Individual part names". The plugs only fit in
the socket with the correct polarity.
• Connect the plug of the connection cables (3 or 4) with the socket „DISP" on the control unit (1).
• Connect the four plugs of the ultrasound sensors (A to D) in the right sequence with the sockets
„A,B,C,D" of the control unit (1). Make sure that the letters on the cables and sockets are in the right
sequence.
After you have made almost all connections, you have to connect the voltage supply.
As the parking aid only works when the reverse gear is shifted, it is supplied by the taillights.
Measure the correct cable with a voltmeter or a diode test lamp when the reverse gear is set and the igni-
tion is on. The lights and the blinkers should be off. If you were able to determine the right cable, turn the
ignition off again.
Connect the red plus cable (5) with the voltage supply cable of the headlight. Make sure that the contact
place is permanently insulated (e.g. insulated clamps, tape, etc.).
With an optional cable cutting connector, you can easily establish safe contact without sev-
ering the light cable.
For this purpose, place the cable cutting connector around the voltage cable of the head-
light and additionally the red conductor of the connection cable (5) into the connector. Use
pliers to press the contact point onto the cables.
