10 Operation
In this chapter, the handling of the OptiTire system is described by means of the WABCO display.
Additionally installed warning lamps indicate the same warning as the display if parameterised
accordingly.
Please refer to manufacturer's operating instructions when operating by means of an
integrated display.
10.1 Warning signals
The colour of the signal light and the type of audio signal indicate the severity of the fault:
Red warning lamp / STOP symbol on the WABCO Display and acoustic warnings at one minute
intervals:
Critical fault: The vehicle must be stopped immediately (potential risk to persons and vehicle).
Yellow warning lamp / turtle symbol on the WABCO Display and acoustic warnings at ten minute
intervals:
Minor fault: The vehicle speed should be reduced and the tire pressure corrected at the next
opportunity.
The faults identied by OptiTire are stored in the ECU for diagnostic purposes.
10.2 Switching on of ignition
After the ignition is switched on, the OptiTire system runs a self-test to check that all the internal
functions are functioning correctly.
All symbols are displayed for one second, all pilot lights and audio signals are enabled. This procedure
is repeated twice.
Initialisation
After initialisation, if tire pressures are within specied values, the following picture will show for a few
seconds:
