Requirements
Vehicle at rest
Level control operating unit (S22) is activated
Function raise/lower overall vehicle is selected or lights up
Function sequence
Pressing the Activate raise/lower buttons (3) activates the raise or lower function.
The level control (CLCS) control unit (A26) receives the signals from the level control operating unit (S22) connected to the modular switch panel (MSF) (A43) over the central gateway control unit (CGW) (A2) and actuates the level control valve unit on the drive axle on 2-axle vehicles (Y21) or the level control valve unit on the drive axle on 3-axle vehicles (Y21a) as well as, with full air suspension, the front axle level control valve unit (Y20).
----------------------------------------------------------------------------------------
The level control valve unit for 2-axle vehicles (Y21) or the level control valve unit for 3-axle vehicles (Y21a) and the front axle level control valve unit (Y20) are pressurize or depressurize the air bellows on the drive axle or front axle, depending on the selected function. The chassis frame is raised or lowered.
In the multifunction display (A1 p1) of the IC (ICUC) control unit (A1) the message "Towing vehicle outside driving level" is indicated as well as the level control indicator lamp (A1 h14) of the IC (ICUC) control unit (A1) being actuated.
The level control function messages are not displayed if the driver is in the Level control menu.
----------------------------------------------------------------------------------------
The left drive axle travel sensor (B24), right drive axle travel sensor (B25) or the front axle travel sensor (B27) sends the change to the frame height to the level control (CLCS) control unit (A26).
As soon as the level control (CLCS) control unit (A26) recognizes the signals from the LH drive axle position sensor (B24), the RH drive axle position sensor (B25) or the front axle position sensor (B27) that the upper or lower frame height limit has been reached then it independently interrupts raising or lowering of the vehicle frame. The vehicle frame therefore remains in the uppermost or lowest maximum position.
If the vehicle frame, and therefore also the cargo area, has reached the desired height, raising or lowering of the vehicle is stopped by pressing the Stop button (4).
The level control (CLCS) control unit (A26) receives the stop signal from the level control operating unit (S22) connected to the modular switch panel (MSF) (A43) over the central gateway control unit (CGW) (A2) and actuates the level control valve unit on the drive axle on 2-axle vehicles (Y21) or the level control valve unit on the drive axle on 3-axle vehicles (Y21a) as well as, with full air suspension, the front axle level control valve unit (Y20) to match the stop signal. The air bellows are no longer pressurized or depressurized.
The frame height is stored by pressing and holding the memory button (M1) (5) or memory button (M2) (6).
The level control operating unit (S22) confirms saving of the frame height by flashing all arrows in the function indicator.
