The process progress is displayed using the progress bar.
The individual process steps are:
Ground contact 1/3: first of all, the cylinders on the lower side
of the vehicle extend until they detect ground contact. Then the
cylinders on the opposite side of the vehicle, i.e. front or rear,
extend until they detect ground contact.
Rough levelling: the vehicle is moved into a stable levelled
position. The aim of this step is to put the vehicle in a favou-
rable starting position and move the vehicle's centre of gravity
into the centre. Rough levelling is carried out with three support
cylinders, which enable a full defined position.
Ground contact 2/3: the fourth support extends until it comes
into contact with the ground.
Precise levelling: the system makes adjustments with the
cylinders moving at a reduced extension speed until the vehicle
lies within a set tolerance range of the saved position.
Ground contact 3/3: finally, a check is carried out on all hydrau-
lic pressures and thus the load capacity of all support cylinders
and these are pushed back to the specified pressure level if
necessary. This results in a levelled position being achieved
with the load uniformly distributed across the individual cylin-
ders.
It is always indicated whether the supports are fully retrac-
ted or not as information for the user. If one of the supports
is partially extended, the „Legs out" icon is displayed.
Semi-automatic mode
