7 Description of faults and troubleshooting

A number of functional errors are listed below which can occur as a result of wear, machine defects, particularly challenging operating conditions,
incorrect operation or a lack of maintenance.
Methods are also described which are aimed at finding and eliminating the problems:
Danger!
• Only open the control unit and carry out maintenance work on the entire machine when the mains plug is disconnected!
• Work on the control unit, sensor board, motor and electrical cables may only be carried out by a qualified electrician.
• In the event of a fault, the mains plug must be disconnected first. The fault must be eliminated only by authorised personnel.
Fault
Display without indicator
Display indicator: A00
– Undervoltage
The brush does not rotate and
the display shows the alarm
"A00".
Display indicator: A01
– Overvoltage
The brush does not rotate and
the display (briefly) shows the
alarm "A01".
Display indicator: A02
– Maximum running time
exceeded
The control unit has not
switched off for 20 minutes
(sensor faulty/incorrectly set)
Cause
The socket is not live.
Fuse 6, 3 A (Fig. 8; item 3+4) on the
circuit board has burned through or
has come loose.
Fuses trip after the unit is operated.
-> Motor short circuit or broken motor
cable
Main board in control unit defective.
Mains voltage too low.
Mains voltage too high.
The motor rotates continuously for 20
minutes (with short pauses between
work cycles).
The display then shows the alarm
"A02".
Main board in control unit defective.
Motor cable broken.
Corrective measure
• Is the fuse in the sub-distribution unit intact?
• Disconnect the control unit from the mains and secure it against
being switched on again.
• Check the secure position of the fuses. Replace defective fuses.
(Fig. 8 – item 3+4)
• If there is no indication on the display when restarting with
replaced fuses, then the main board is defective.
• Have the motor and motor cable checked by a qualified elec-
trician
• Replace the main board.
• Have the mains checked by a qualified electrician.
• Check whether the mains voltage is above 200 V.
• Ensure that no other major consumers are supplied via the same
current circuit / fuse.
• Have mains voltage peaks measured by a qualified electrician.
• > 260 V, find the causes of these peaks and eliminate them.
• The LED on the sensor board (Fig. 11) lights up in the rest positi-
on. Restart the unit. The sensor is recalibrated.
• The LED on the sensor board remains lit in the rest position after
restart -> replace the sensor board.
• Replace the main board.
• All wires of the motor cable have continuity?
• External insulation intact?
• Replace motor cable if damaged.
