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.
