Pneumatic control (1-line system)
First you must set the desired pressure values for
road and field travel via the pressure gauge on the
outside of the vehicle. These values are then saved
by the system. They can be adjusted at any time.
The driver simply selects the desired
mode (road or field) via the control
console in the cab and the control
system sets the preconfigured value
on all tyres.

9.9.2
ISOBUS control (2-line system)
The system is connected to the compressed air
brake system via a safety valve to ensure a constant
supply pressure of 6.5 bar in the brake reservoir.
Due to the high-volume tyres on the vehicles,
separate/additional air supply systems are generally
required.
A number of different air supply systems are
available, which cut in and out automatically when
necessary.
The system is operated from the cab via the ISOBUS
control.
