Air suspension
– Within 5 seconds after switching off the ignition, the delay (standby) setting is
activated. Whit this setting activated, only the height adjustment remains active for
60 minutes or until the air supply has become insufficient. The remote control
functions are inactive when the ignition is switched off.
– While lifting or lowering a liftable axle, the electropneumatic valve for the lift bellow
is cut-out immediately. The liftable axle stays at the actual position. The liftable axle
is lowered when the driving speed exceeds 8km/h.
Pressing any of the other keys reactivates the air suspension. Unless stated otherwise,
the keys need only be pressed once briefly.
NOTE: If the 'Stop' key is pressed before inflating of the lift bellow has
started, the stop function is aborted. After a few seconds the air suspension
returns to normal height and pressure ratio control.
12.5 SETTING MEMORY KEYS (M KEYS)
– Bring the chassis to the desired height using the keys 'Lower chassis' or 'Lift
chassis'.
– Press the 'Stop' key and keep it pressed.
– Press either of the 'M' keys briefly. The momentary chassis height is programmed
in the ECAS unit.
If this 'M' key is pressed again, the vehicle adjusts itself to this programmed chassis
height.
A different chassis height can be programmed with the other 'M' key in the same way.
12.6 AXLE LOAD MONITORING
General
The Axle Load Monitoring system is used to show the actual axle loads. Using the
MCS, the individual axle loads and the load's weight can be activated and shown on
the master display.
The axle load is only shown when the ignition is switched on and the vehicle is
stationary and at normal driving height.
