Electronic air suspension

This is an air suspension system controlled and monitored by an electronic microprocessor
based device. On top of the advantages of a conventional air suspension system, it contrib-
utes the following benefits:
– optimization of loading bay services and memorizing of the last level setting (even
after a power cut);
– automatic level correction to bring the suspension parallel with the centre-line of the
vehicle (even if the load is poorly distributed);
– savings on tyre wear (with lift-up axle option);
– operations piloted by one remote control box (or by dashboard switches for 4x2
vehicles without remote control);
– reduced number of air lines;
– speedy adjustment of level and low air consumption;
– built-in safety systems (alarm, fall-back operating procedures);
– system programming depending on the vehicle and legislation in the country of use;
– above 10 km/h, return of the chassis to the normal level.
Operation
– Automatic mode
The system keeps the suspension at a normal level, defined by programming.
– Manual mode
Manual mode is programmed, but operation in manual mode is only possible at speeds
below 10 km/.
The manual mode allows the height of the chassis to be adjusted to the required level.
To return to automatic mode, press the button on the remote control (normal level) (or
press the dashboard switch on 4x2 vehicles without remote control) or when the road
speed is above 10 km/h.
– Information pictogram (G47)
This pictogram is illuminated when the vehicle level is different from the normal level.
– Alert pictogram (G29)
This pictogram is displayed as soon as a fault is identified. The electronic box safety
device automatically neutralizes the control system, partly or in full..
On the road
Pictogram (G29) is displayed when a suspension malfunction has been detected.
When stationary
Pictogram (G29) is displayed when a suspension malfunction has been detected. Run a test
(see page D1-19).
When taking the road
When the vehicle moves off, the suspension height is only taken into consideration when
the parking brake is released .
