Start-up Operation
4 . Sensor sensitivity settings
– In the diagnosis, click on System => Parameter .
The settings are made via the tab (
10) Electronic
Extension Module (System => Parameter)
.
Fine adjustments
The fine adjustment can be implemented within the range from 90 % to 130 %.
This may be necessary if the selected sensor sensitivity must be adjusted a
little. This chiefly concerns vehicles with complex rear body structures.
Sensor sensitivity
The following settings are possible in the area Sensor sensitivity :
„
Sensitive:
High detection capability in close proximity (as delivered).
Recommended sensor sensitivity for the upper sensor level with
TailGUARDMAX and for TailGUARD with low sensor spacing ( < 1.5 m).
„
Standard:
The ultrasonic sensor sensitivity is reduced a little at close range
to mask out objects that are permanently attached to the trailer and can
cause reflections (rubber buffers, etc. for instance). This setting should be
used with TailGUARD
Roof
for the top two ultrasonic sensors.
„
Ground level:
The ultrasonic sensor sensitivity is reduced a little at long
range to mask out reflections caused by objects on the ground (curbs for
instance). This setting should be used if the ultrasonic sensors are installed
lower than 50 cm (e.g. for the lower sensor row with TailGUARDMAX).
!
For vehicles with problematic detection rates, WABCO recommends repeating
the settings in the open (without reflections from walls or other vehicles).
8 .5 .2 Reduced EOL test
Under
Options => Settings => Test options
in the diagnostic software, test steps
can be deselected under the following conditions:
Requirements for deselecting the object test
„
The system has already been successfully adapted and tested on many
vehicles of identical design.
„
The distance between the left and right ultrasonic sensor is 1.6 - 2.4 m.
„
With 3 ultrasonic sensors the middle ultrasonic sensor must be positioned
centrally. The maximum deviation from the centre axis is 30 cm.
„
The installation depth of the ultrasonic sensors is max 35 cm.
Deselecting the reflections test
If you have sufficient experience with TailGUARD on a recurrent vehicle type,
the test for reflections can also be simplified.
After carrying out the test for the first time, the interference echo values must be
written to a file (provided interference echoes were found). The content of this
file is then copied into the ECU file and transferred to the vehicles that follow.
