7 Troubleshooting
Error Cause Corrective action
LEDs (5, 6, 7, Fig. 1) do not
light, pressure discs will not
move.
• The unit is not switched on. • Switch the unit on at the main power switch (16,
Fig. 1).
The unit does not switch on. • Power cord not properly connect-
ed to the unit.
• Fuse blown.
• No power at the wall outlet.
• Unit fault.
• Check that the unit plug is properly seated
(Fig. 2).
• Replace the fuse (refer to Sec. 6.5).
• Check that there is power at the wall outlet.
• Return the unit for repair.
Pressure discs will not
move, ”Unit cover” LED (7,
Fig. 1) is on or flashes.
• Unit cover not properly closed. • Close the unit cover (8, Fig. 1) and check that the
cartridges are properly seated. If required, seat
cartridges correctly.
Pressure plates move very
slowly towards the cartridge.
• The cover was opened before the
pressure plates stopped. A previous
cartridge position has been saved.
• Press retract key (4, Fig. 1) and wait until the pres-
sure plates have reached their home position and
have come to a complete stop. Then repeat the
process with the cartridge.
Cartridges cannot be re-
moved / cannot be installed.
• Pressure discs have not fully re-
tracted to their home position.
• Press the retract key (4, Fig. 1) and allow the
pressure discs to retract until they stop automati-
cally. They are now in their home position (refer to
Sec. 5.1).
A loud sound can be heard
when the mixer shaft threads
itself into the mixing nozzle.
• A spring pushes the mixer shaft
forward until it reaches a stop.
• This is perfectly normal and requires no interven-
tion.
• Only install the mixing nozzle subsequently.
Mixing nozzle (21, Fig. 1) is
not turning.
• The mixer shaft has not threaded
itself.
• Material has hardened in the mix-
ing nozzle.
• The mixer motor’s thermal protec-
tor has activated.
• Check that the cartridge is properly seated.
• Install a new nozzle.
• Allow the unit to cool down for approx. 30 min-
utes, Observe the maximum permissible operating
time (2 minutes of operation, 5 minute pause).
Unit automatically reduces
the Extrusion speed.
• Unit detects a highly viscous im-
pression material and automatical-
ly reduces the feed rate and mixer
rotary speed.
• Contamination (e.g. debris) in the
cartridge holder.
• Insufficient spindle lubrication.
• The pause time was not observed.
• This only occurs if the material is highly viscose or
is cold. Refer to the manufacturer’s processing in-
structions (processing temperature).
• Clean the inner surfaces of the cartridge holder
and pressure plate.
• Lubricate the spindles (special grease!).
• At least 5min intermission.
The mixing nozzle bursts
(21, Fig. 1).
• Incorrect mixing nozzle installed.
• Mixing tip/ foil bag not compatible.
• Use the mixing nozzle specified by the manufac -
turer.
• Contact the manufacturer of the mixing tip / foil
bag.
The tubular bag bursts or is
damaged.
• Pressure discs are too worn or
have been damaged, causing the
tubular bag to be pinched between
the pressure disc and the car-
tridge.
• The material has partially hard-
ened in the cartridge.
• Replace the pressure discs (refer to Sec. 6.3).
• Replace the cartridge (refer to Sec. 5.1).
