The letter from a suction
channel is blinking and
the suction channel can-
not be opened.
It is not possible to
change between single
and multi use mode.
There is no audible sig-
nal.
Suction hose cannot be
closed by pressing the
suction hose button.
The extraction unit re-
quires filter cleaning at
frequent intervals.
The suction does not
start when an electrical
appliance connected to
the QCB is activated.
The electrical appliance
connected to the QCB
cannot be operated.
Suction begins, even
though no appliance
connected to the QCB
has been activated.
The suction does not
stop when the electrical
appliance is switched
off.
The fault "Err14" ap-
pears when program-
ming the on / off thresh-
old for a handpiece.
Possible Cause
• The suction channel is closed and the
switch off threshold has not yet been
reached.
• In the single use mode only one suc-
tion channel can be opened at a time.
There is currently a suction channel
already open.
• A suction channel is still open.
• The audible signal is deactivated.
• An electrical appliance connected to
the QCB is still in use.
• The diameter of the suction tube is
too narrow, because a small suction
port was connected to the the suction
point.
• The fine filter unit is so dirty, that it is
no longer possible to clean.
• The system has a leak.
• The extraction unit is not switched on.
• Device fuse has been triggered.
• QCB is not connected with the ex-
traction unit.
• On / off threshold of the suction chan-
nel is too high.
• A connected remote control has pri-
ority over the QCB for this suction
channel.
• QCB is not connected to a power sup-
ply.
• The on / off threshold from the suction
channel is too low.
• The electrical appliance was not con-
nected to the QCB.
• The on / off threshold is set too low.
• A connected remote control has pri-
ority over the QCB for this suction
channel.
• The rpm you have selected on the
handpiece means the difference be-
tween stand-by power and operating
current is too low.
Corrective Action
• No fault.
• Close one open suction channel first and then open
the other.
• Select the multi use mode, but to do so all suction
channels must first be closed.
• Close all suction channels.
• Activate audible signal (Section. 5.6.2).
• Switch the appliance connected to the QCB off, see
section 5.4.4.
• Use the original suction tubes and install a suction
port adapter if necessary (see accessories).
• Change fine filter adapter (section. 6.2).
• Check to make sure that the dust drawer and the fine
filter unit have been replaced correctly and that the
seals are not damaged.
• Check to make sure that the dust area cover panel
has been replaced correctly and is fixed securely in
place.
• Check to make sure the pinch valve seals are secure.
• Switch the extraction unit on (section 5.1).
• Check fuses, if necessary replace fuse (section 6.3.1).
• Connect the QCB to the extraction unit (section 4.6.1).
• Adjust the on / off threshold (section 5.6.4).
• Press the mouse scroll wheel from the relevant suc-
tion channel to give the QCB priority again.
• Connect the QCB to a power supply (section 4.6.1).
• Check which suction channel is open, the relevant
letter will be shown in the display.
• Adjust the on / off threshold from that particular suc-
tion channel (Section 5.6.4).
• Connect the electrical appliance to the QCB (section
4.6.2).
• Adjust the on / off threshold (section 5.6.4).
• Press the mouse scroll wheel from the relevant suc-
tion channel to give the QCB priority again.
• Program a higher rpm on the handpiece to activate
the on / off threshold.
