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-

Error messages (power source)

Depending on the options of the machine display, a fault is shown as follows:
Display type - machine control
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.
