The Sunny Island has a very powerful system management. It makes it possible to
adjust the controlling behavior of the Sunny Island precisely to the connected island
grid and its components. To be able to optimize the required settings it is helpful to
have a look at the history of the plant’s behavior. However the operator should not
be dependent on a PC that has to be operating all the time to be able to view these
data. Therefore the Sunny Island continuously not only acquires changes of its oper-
ating state (“events“), but also any excess of a limiting value or error (“alerts“).
“Alerts“ are to be distinguished into more serious ones that the user has to confirm,
and less serious ones which are merely recorded in the error list (see chapter 17).
The “DIAG“ (0-4) menu selection shows the error status of the system. The menu
branch itself comprises detailed lists of the latest errors and system states. For a
clear distinction “events“ are marked with an “E“ in front, “alerts“ with an “A“.
