Sensor Power Connection
Though the sensor communicates wirelessly to the display unit, it still requires a
wired connection to provide power and ground. Locate the vehicle’s reverse light
power wire and connect to the red wire on the sensor harness using 18AWG wire
minimum. Connect the black wire of the sensor harness to vehicle ground.

Initial System Power Up and Test
Once the sensor and WD7102 wireless display are installed, wired, configured,
and connected, power should be applied to test correct system operation by
energizing the machine and placing it into reverse. Follow the instructions in
the display manual (3700076_) to properly configure the display and connect
it to the sensor. When the system is operating correctly in an open field with no
obstructions, the display should be showing the “Clear” screen. If the display is
indicating a detection and there is no object in the machine’s vicinity, check for
any objects on the machine which may be detected by the sensor. If possible
move the sensor so it is not detecting the object(s). If it is not possible to relocate
the sensor then consult Preco Customer Service.
If for some reason the display is showing the “Not In Reverse” or “Sensor Not
Communicating” screen when the machine is in reverse, verify the display
is configured correctly see the display manual (3700076_). If the display is
configured correctly and the Troubleshooting section has been reviewed, please
contact Preco Electronics.
Once the system has been installed, the detection zone should be tested. This
test should be performed with two people, one who remains in the cab (the
operator), and one who walks through the sensor field at the rear of the vehicle
(the assistant). The operator engages the parking brake, depresses the machine
brake, and places the machine in reverse. The assistant then walks through the
detection zone while the operator in the vehicle cab notes where the display
indicates a detection. By moving about the rear of the machine and noting when
the display indicates a detection, an accurate detection zone can be mapped.
