Faults and malfunctions
6.1
Display of events
Events occurring during operation can be displayed via the menu path: "Choice 2/2" -> "System" -> "Incidence memory" and
after entering the specialist password (see Section 5.3.4 and Image 5-5). For this purpose, the Solaris control unit contains a
simple fault diagnosis system. The incidence memory stores nature and time of the event. The event is displayed in plain text and
a code, the time since the event occurred is shown in hours. Starting with the most recent event, you can leaf through the
individual events by means of the Info key. If the "Delete" parameter in menu path: "Choice 2/2" -> "System" -> "Incidence
memory" is set at "Yes", all events will be deleted. Deletion of individual events is not possible. An overview of the possible entries
in the incidence memory can be found in Table 6 -1.

not achieved in the start phase after "Time
