Aux. Output Electrical Connection
This sensor provides an auxiliary output that can be used to activate an external
backup alarm or other device (white wire). Depending on the system ordered,
the cable provided may or may not have provisions to access this output.
The aux. output is activated whenever an object is detected. The output is switched
from a high impedance state to ground when active and is protected against an
over current condition. The maximum operating current is approximately 1 amp,
this includes any inrush current. For alarms or other devices that meet the 1 amp
maximum current, connect the aux. output wire on the interconnect harness to
the ground wire of the alarm or device. For alarms or devices that exceed the 1
amp current limit an intermediary relay must be used.
Display Unit Installation
The display unit should be mounted where the vehicle operator can easily view
it while backing. The ideal location for this is on the dash positioned by either
windshield pillar. This will allow the operator view of the display while also looking
out one of the side mirrors.
The WorkSight PreView display unit comes equipped with a mounting bracket
and hardware. If desired, the display unit can be mounted to the display bracket
with the supplied hardware. This bracket can then be mounted in the vehicle cab
as desired.
Cable Installation
The standard interconnect cable between the sensor and display is 30 feet (9.1M)
in length. If the distance between the sensor and display is greater than 30 feet,
contact Preco for a longer interconnect cable.
Sensor Power Connection
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.
