Indicator field
(Fig. 19/1) The indicator field enables
the scrubber drier to provide feedback
on the operating status of the vehicle.
This only relates to operating states
which cannot be switched on and off via
the operating panel: recovery tank full,
dirt hopper for pre-sweep/vacuum unit
full, parking brake applied and error
message.
The individual buttons and functions are
described in detail below:
Indicator for recovery tank
maximum fill level
(Fig. 19/2) The yellow con-
trol lamp lights up when the
recovery tank has reached
its maximum fill level. Also, a "beep"
signal is issued every 15 seconds. In
this case, a float switch switches the
suction turbine off and the squeegee is
raised.
Indicator for dirt hopper
and front flap of pre-
sweep/vacuum unit
(Fig. 19/3) The control lamp
lights up red when the dirt hopper is not
properly inserted (engaged) or the front
flap is not properly closed.
Indicator for parking brake
applied
(Fig. 19/4) The control lamp
lights up red when the park-
ing brake has been actuated
via the pedal to the left of the steering
column. If the traction drive is switched
on, an acoustic signal is also issued.
