20 Troubleshooting
In general the Sunny Island distinguishes between events and errors.
•
Events
describe state changes or transient states (e.g. generator connection).
•
Failures
describe states that are not permitted or are only permitted up to a certain rate. This
includes warnings, failures and errors. A user interaction is generally required.
20.1 Failure Confirmation
If there is a disturbance or failure, the Sunny Island goes into standby.
Proceed as follows to confirm a failure:
1. Remove the cause.
2. Confirm failure with <ENTER>.
3. Start the Sunny Island again.
20.2 Autostart Handling
The Sunny Island has an autostart counter which counts down by 1 with every automatic start. After
10 minutes of normal operation of the Sunny Island, the autostart counter is set back to its original
value.
If another failure occurs when the autostart counter is at 0, the Sunny Island waits for 10 minutes and
then attempts to restart. The autostart counter begins to run again.
The number of the autostarts allowed can be set using the ”250.01 AutoStr” parameter (in standby
mode).
20.3 Master Slave Handling
Each device detects the failures separately and saves it. The slaves transfer their failures to the master.
The master collects these failure messages and enters the slave failures as warnings into its history.
Example:
Slave 1 has detected overtemperature. It enters this failure 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 line on the
master.
If warning 138 is still active on slave 1, the Enter symbol is displayed at the end of the line.
After confirmation on the master using ENTER, the warning is forwarded to the corresponding slave.
