Problem Possible cause Solution / Correction
After switching on,
nothing can be
seen on the display
or only black bars
appear
Mains voltage under 350 V • Connect the device to a higher voltage outlet.
• Use a voltage transformer
One phase missing in the
power supply
• Check the fuses at the customer’s power supply
• Have an electrician check whether all three phases are
present and connected correctly (socket and plug of the
machine)
Defective display • Send the unit back to the manufacturer for repair
(see above the section "Service and maintenance")
The shrinking proc-
ess is aborted after
a short period of
time (approx. 0.5
sec)
Major drop in the supplied
voltage
• When using an extension cable: Connect the device
directly with the outlet or try using a cable with a larger
cross-section.
• Connect the device to a higher voltage outlet
• Run a separate feed directly from the main distributor to
the shrink fit machine.

Device defective • Send the unit back to the manufacturer for repair
(see above the section "Service and maintenance")
Tool or extension
cannot be unshrunk
properly
General notes • Do not use excessive force to remove the tool from the
chuck. The clamping hole and shank could be damaged
• Do not temper the chuck
For adjustable coils and
clamping diameter 3 – 5 mm
• Use insert ring
Shank diameter is too great • Only use tools with a shank tolerance of h6
Tool shank is dirty or dam-
aged (ridges, scratches, dents)
• Clean the tool shank before shrinking in
• Use undamaged tools only
• Correct any unevenness (truing)
Wrong parameter settings at
the device
• Set the correct setting in the display
Chuck holder not cooled
down completely
• Always cool the chuck holder completely before using it
again
Chuck overheated (glowing) • Shrinking and unshrinking are no longer possible. Send
the chuck with the tool to the manufacturer, repair may
be possible
Mains voltage too low • Connect the device to a higher voltage outlet
• Use a voltage transformer
Power supply unstable. Volt-
age display sinks to under
495 V during the shrinking
process.
• When using an extension cable:
Connect the device directly with the outlet or try using a
cable with a larger cross-section.
• Connect the device to a higher voltage outlet
• Run a separate feed directly from the main distributor to
the shrink fit machine
