Troubleshooting
Even carefully designed and manufactured technical systems that are
operated properly, may experience malfunctions. Table G-1 provides

of the systems and indicates the causes and their elimination.
The systems are equipped with an error detection and reporting
system.
If an error message is displayed:
1. Press button (= acknowledge malfunction).
2. Watch the display.
If the message reappears, compare it with table G-1.
3. If necessary, notify Grünbeck’s technical customer service.
