20 Troubleshooting
In general, the Sunny Island distinguishes between events and errors.
• Events describe state changes or transient states (e.g. generator connection).
• Errors describe states that are not permitted or are only permitted up to a certain rate. This
includes warnings, distrubances and errors. User interaction is generally required.
20.1 Error Acknowledgement
If a disturbance or error occurs, the Sunny Island goes into standby.
Proceed as follows to acknowledge an error:
1. Eliminate the cause.
2. Confirm error with .
3. Start the Sunny Island again.
20.2 Autostart Handling
The Sunny Island has an autostart meter which counts down by 1 with every automatic start. If the
Sunny Island runs uninterrupted for over ten minutes, the autostart meter is reset to its initial value.
If another fault occurs when the autostart meter is at 0, the Sunny Island waits for ten minutes and then
attempts to restart. The autostart meter begins to run again.
The number of autostarts allowed can be set using the parameter "250.01 AutoStr" (in standby
mode).
20.3 Master-Slave Handling
Each device detects the errors separately and saves them. The slaves transmit their errors to the
master. The master collects these error messages and enters the slave errors as warnings into its
history.
Example:
Slave 1 has detected overtemperature. It enters this error in its history and reports it to the master,
which also enters it as a warning into its failure history ("Menu 420# Failure History").
The following message appears in the lower display line
on the master.
If warning 138 is still active on slave 1, the Enter symbol appears at the end.
After the warning has been confirmed on the master by pressing the key, it is forwarded to
the respective slave.
The master shows the following message after
confirmation.
