Form and positive recognition
The area behind the vehicle is monitored up to the vehicle width and a distance of
max. 2.5 - 4 m (depending on system, object size and surface) back behind the
vehicle.
If an object is located within the monitoring area of the sensors, the distance indi-
cated as follows:
• Flashing clearance lights with varied frequencies
• Display on the LED bar in the optional Trailer Remote Control
• Changing tone frequency of the beeper in the Trailer Remote Control
• Optional, external buzzer (not included in WABCO scope of delivery)
• Optional, external signal lights (not WABCO supplied) for countries, in which
flashing clearance lights are not allowed, such as Great Britain or Switzerland
If the ultrasonic sensors are raised to a height at which parts of a ramp are located,
the system can also be used as ramp approach support.
An external acoustic signal transmitter can be connected to GIO14 / Pin 1 (ELEX).
When using the Trailer Remote Control, the driver in the cab is notified by an
acoustic signal as well as a visual indication of the position and the distance of de-
tected objects.
Acoustic and visual driver information
The changes in lamp and buzzer frequencies occur at distances of 3 m, 1.8 m and
0.7 m.
The buzzer is not to be used as the only distance output because it is not possible
to clearly indicate a malfunction.
