7 Faults and malfunctions
7.1 Display of events
Using the menu path: "Selection 2/2" -> "System" -> "Event
memory" and, after entering the technician password
(see section 6.3.4 and fig. 6-7), any events that occur during op-
eration can be displayed. The Solaris R4 controller has a simple
fault diagnosis system for this purpose. The events memory
stores nature and time of the event. The event is displayed in
clear text and using a code, the time since the start of the event
is displayed in hours. Starting with the most recent event, you can
leaf through the individual events by means of the Info key.
If the parameter "delete" is shown in the menu item:
"Selection 2/2" -> "System" -> "Event memory" is set to "yes", all
events are deleted. Deletion of individual events is not possible.
An overview of possible entries in the event memory is given in
tab. 7-1.
