G Troubleshooting
Even carefully designed and manufactured technical systems that are
operated properly, can experience malfunctions. Table G-1 provides
an overview of possible problems that can occur during the operation
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.
Note:
In the case of malfunctions which cannot be remedied with the
information in Table G-1, it is essential to contact the customer service
(refer to www.gruenbeck.de)! Enter the system designation, serial
number and, if necessary, fault signal in the display.
