6 Faults and malfunctions
Using the menu path: "Selection 2/2" -> "System" -> "Event memory" and after input of the technician password (see
chapter 5.3.4 and figure 5-9) the events occurring during operation can be displayed. The Solaris R3P control system has 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 parameter "Delete" is in the menu path: "Selection 2/2" -> "System" -> "Event
memory" is set to "yes", all events are deleted. Deletion of individual events is not possible. For an overview of the event memory
see table 6-1.

Sensor-specific fault signals
In the case of wire break and short-circuit in sensors or sensor cables the Solaris R3P control system responds as follows
(see table 6-2):
– The display shows a flashing identification letter for the malfunction in the status column and a message appears.
– The lamp associated with the sensor flashes.
– The Solaris R3P control system also automatically intervenes in the operation of the system.
All other sensor values remain accessible via the arrow keys.
