Rectifying faults
All products are subject to rigorous production checks and final checks. If, despite this, something fails to
work at any time, please check the product using the following flowchart. If none of the fault rectification
procedures described leads to the correct functioning of the product, please inform your authorised dea-
ler.
7.1 Error messages (power source)
Depending on the options of the machine display, a fault is shown as follows:
Display type - machine control
Display
Graphic display
two 7-segment displays
one 7-segment display
The possible cause of the fault is signalled by a corresponding fault number (see table). In the case of an
error, the power unit shuts down.
The display of possible error numbers depends on the machine version (interfaces/functions).
• Document machine errors and inform service staff as necessary.
• If multiple errors occur, these are displayed in succession.
• Document machine warning and inform service personnel, if required.
• If there are several errors in a control system, the error with the lowest error number (Err) is displayed.
If this error is corrected, the next higher error number appears. This process is repeated until all errors
have been resolved.
Categories legend (resetting the error)
a) The error message will disappear once the error has been rectified.
b) The error message can be reset by pressing a push-button :
c) The error message can only be reset by switching the machine off and on again.

Tacho error
Error of wire feeder
Check connections (connec-
tions, pipes)
Permanent overload of the wire
drive
Do not place the liner in tight
radii; check wire core for
smooth movement
4
Excess tempe-
rature
Power source overheated
Allow the power source to
cool down (mains switch to
“1”)
Fan blocked, dirty or defective Check fan and clean or re-
place
Air inlet or outlet blocked
Check air inlet and outlet
5
Mains overvol-
tage
Mains voltage is too high
Check the mains voltages and
compare with the power
source connection voltages
6
Mains under-
voltage
Mains voltage is too low
7
Low coolant le-
vel
Flow rate too low (< = 0.7 l/min)
/ (< = 0.18 gal/min)
[1] [3]
Check coolant flow, clean wa-
ter block, remove kinks in
hose package, adjust flow
threshold
Coolant volume too low
Fill coolant
Pump does not run
Turn the pump shaft
