procedures described leads to the correct functioning of the product, please inform your authorised dea-

7.1 Error messages (power source)
The possible error numbers displayed depend on the machine series and version!
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.
• 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.
