G Troubleshooting
Even carefully designed and manufactured technical systems that are
operated properly, may experience malfunctions. Table G-1 provides
an overview of possible problems that may occur during the operation
of the systems and indicates the causes and their elimination.
The systems are equipped with an error detection and reporting sys-
tem. If an error message is displayed:
1. Press P button (= acknowledge malfunction).
2. Watch the display.
If the message reappears, compare it with table G-1.
3. If necessary, notify Grünbeck’s technical service.
Note:
The technical service definitely must be notified (refer to
gruenbeck.de) in case of malfunctions that cannot be remedied with
the information given in table G-1! When contacting the technical ser-
vice, please indicate the system designation, serial number and the
error message displayed.
