Sleep mode
To minimise electricity consumption the
control system switches to “system idle”
(sleep mode) after 15 minutes.
There is no level adjustment in sleep mode.
“Wake-up” is primarily triggered by the door
switch signal.
If the door switch signal fails, the system is
activated when the ignition is switched “ON”
or by the driving speed signal.
The system can switch between sleep mode
and run-up mode, triggered by the door
switch signal, a maximum of 5 times. After
this, the system can only be activated via
terminal 15 and/or the driving speed signal.
Run-on mode/run-up mode
After “Ignition OFF”, the control system is in
the so-called run-on/run-up mode. The
control unit remains active for a maximum of
15 minutes (via terminal 30) until it goes into
sleep mode.
The run-on/run-up mode is used to adjust
level deviations after parking the vehicle or
prior to starting on a journey.
The limit value in the rebound direction is
increased by 25 mm in the run-on/run-up
mode so that when the driver and/or the
passenger re-enters the vehicle, it does not
sink lower than the reference level or in order
to minimise any necessary vehicle raising
period.
The same response times apply as those
indicated for the stationary mode.
