Operation
Indicator field
(Fig. 17/1) The indicator field enables the
Admiral 38C to provide feedback on the
operating status of the vehicle. This only
relates to operating states which cannot be
switched on or off via the operating panel:
recovery tank full, parking brake applied
and error messages.
The individual buttons and functions are
described in detail below:
Indicator for recovery tank
maximum fill level
(Fig. 17/2) The yellow control
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 parking brake
applied
(Fig. 17/3) The control lamp lights
up red when the parking 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.
Indicator for function faults
(Fig. 17/4)
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 indicator
(Fig. 17/5). This error code infers which
fault has occurred (refer to Section 3.5.1).
At the same time, the control lamps flash
and an acoustic, pulsating signal is issued.
Operating hours counter
(Fig. 17/5) The four-digit
LED serves to display the
operating hours. When the
key in the key switch is turned on, one and
then two four-digit codes appear in suc-
cession (for further details, refer to Page
36, Key Switch (Fig. 18/1)). The operating
hours appear after this.
The counter only operates when consum-
ers are switched on (e.g. hydraulic or
brush motor, suction turbine). At the same
time, a red dot flashes at the bottom right
of the display.
Service indicator
(Fig. 17/5) The same LED
also serves for a more
accurate determination of
function faults. If a fault
occurs during operation, a four-digit code
(error code) appears in the service indica-
tor display. At the same time, the four
dots of the error code flash in the display
and a pulsating acoustic signal is issued.
The control lamp in the functional fault
display lights up red. Section 3.5 provides
an overview of the error codes which
help you clear functional faults yourself.
Clear the fault before starting to use the
vehicle again. If you cannot clear the fault
yourself, note down the error code and
inform the authorized PowerBoss
dealer
responsible for your vehicle.
