exceed the maximum speed permitted for the
environment.
• Entering a hall
Theceilingdetectorsystemau
tomatically
detects whether the truck ente
rs a hall. The
system then automatically slo
ws the truck to
the maximum speed that is set
for the hall.
• Leaving a hall
If the truck leaves the hall again, the ceiling
detector system enables the maximum
speed set for areas outside the hall. Due
to the range of the sensor, this may not
happen until the truck is a few metres away
from the hall exit. Before the truck is able to
accelerate to the maximum speed permitted
for outdoor areas, the speed limitation must
still be unlocked. To do this, release the
accelerator briefly and then operate the
accelerator again.
• Switchingonthetruckina
hall
If the truck is switched on inside a hall, the
ceiling detector system detects the hall
ceiling and reduces the driving speed to the
maximum speed that is set for halls.
Possible limitations for object recognition
• If the truck moves under larger overhead
structures outdoors, e.g. a pedestrian
bridge, the ceiling sensor system may
interpret this overhead structure to be a hall
ceiling and reduce the maximum speed.
• In rare cases, it may occur
that the ceiling
sensor system does not reco
gnize a ceiling
and does not then reduce the sp
eed. This
can happen if the signals from
the ceiling
sensor are insufficiently refl
ected due to the
ceiling geometry; for examp
le, if there are
large window areas at a 45° an
gle.
In these cases, the sensitivity and the range of
the ceiling sensor system must be adjusted.
