Trouble
The display "empty dust
drawer" blinks and an
EN
acoustic signal occurs
3 times.
The suction process in
the continuous operation
or automatic operation
stops abruptly and the
relevant displays are still
on (20 / 22, Fig. 2).
The suction unit does not
respond to signals from
the CAM system.
After the suction motor
was changed, the suction
unit stopped functioning
or stops suddenly.
Possible Cause
• The flow velocity is insufficient; the
filter cleaning function is carried out.
• The suction turbine is overheated.
• The suction turbine is defect.
• Plug on CAM system or suction is
not correctly inserted.
• Interface cable damaged.
• Plug assignment of the interface
cable does not correspond to that of
the CAM system.
• The plug from the suction motor is
not sufficiently clicked in place.
Corrective Action
• Wait until the filter cleaning has finished.
• Switch the unit off and allow to cool down for at least
60 min.
• Check whether the suction tube is blocked. Eliminate
blockage.
• Switch the unit off and back on in order to initiate the
filter cleaning function.
• If the filter cleaning does not improve the situation,
change the fine filter (see chap. 6.3).
• Change the suction turbine.
• Check the plug on the suction system and the CAM
system.
• Check interface cable for damage, replace if neces-
sary.
• Check the connector assignment of the interface ca-
ble with that of the CAM. If necessary, use the correct
interface cable.
• Connect the suction motor plug correctly.
Ensure that the plug is fitted correctly and clicked into
place by pulling it.
