Step monitoring
For the SensoPart, a step monitoring function can be activated via parameter. The step
monitoring function is only active if the vehicle, while a travel command is pending, has
stopped and is at standstill due to the distance to the SensoPart sensor.
The step monitoring function is not active during travelling or if the vehicle is at standstill
due to a switched−off travel command.
If the control in the buffered state detects a step in the distance of the SensoPart sensor,
for a parameterisable time a warning signal is only shown on the display. After the time has
elapsed, this warning signal changes to a fault signal.
The warning signal and also the fault signal will delete automatically when the SensoPart
sensor detects a correct dístance value again (i. e. when it can "see" the mirror of the
vehicle in front again).
The fault signal must be acknowledged manually at the control if the SensoPart sensor can
no longer detect a distance to the vehicle in front (for instance, because the vehicle in front
has moved in the meantime).
After the step monitoring function has responded, the vehicle will start as usual if ...
ƒ
the SensoPart sensor reports a correct distance which has exceeded the stop
distance parameterised (plus hysteresis) (i.e. "sees" a mirror).
ƒ
the fault signal on the vehicle has been acknowledged manually and the SensoPart
sensor does not detect a mirror in front. PLEASE NOTE: This may also occur if the
fault signal is acknowledged while a person is standing in front of the vehicle.
The "Step monitoring function activated" status (i. e. distance has changed abruptly and
this state is still pending) is saved non−volatilely. If the SensoPart sensor still does not
detect a mirror after mains on/off, the warning signal and then the fault signal is output
again.
