Operation
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,
parking brake applied and error mes-
sage.
The individual buttons and functions are
described in detail below:
Indicator for recovery tank
maximum fill level
(Fig. 19/2)
The yellow control
lamp lights up when the recov-
ery tank has reached its maxi-
mum 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 parking brake
applied
(Fig. 19/3)
The control lamp
lights up red when the parking
brake has been actuated via
the pedal to the left of the steering col-
umn. If the traction drive is switched on,
an acoustic signal is also issued.
Indicator for function faults
(Fig. 19/4)
The control lamp lights up red
when one of the following
faults occurs:
• The thermostatic switch disconnects
from the brush or hydraulic motor.
• One of the safety fuses is defective
or an electronic fuse has been
tripped.
• Another fault has occurred.
At the same time, a four-digit code ap-
pears in the display of the service indi-
cator (Fig. 19/5). This error code infers
which fault has occurred (refer to Sec-
tion 3.5.1). At the same time, the control
lamps flash and an acoustic, pulsating
signal is issued.
