Technical Description
21 Troubleshooting/Problem Solving
In principle, the Sunny Backup 2200 makes a distinction between events and errors. These messages
are displayed on the external Sunny Remote Control 1 display.
•
Events
describe state changes or transient states (e.g. firmware update).
•
Errors
describe impermissible or only limited permissible states. This includes warnings, failures
and errors. A user interaction is generally required.
21.1 Error Confirmation
If a fault or an error occurs, the Sunny Backup 2200 switches into standby mode.
Proceed as follows to acknowledge an error:
1. Correct the cause.
2. Confirm the error by pressing the button of the Sunny Remote Control 1.
3. Restart the Sunny Backup 2200.
21.2 Autostart Handling
The Sunny Backup 2200 has an autostart meter that counts down by 1 for each autostart. If the Sunny
Backup 2200 runs uninterrupted for over 10 minutes, the autostart meter is reset to its initial value.
If another fault occurs when the autostart meter is at 0, the Sunny Backup 2200 waits for 10 minutes
and then attempts to restart. The autostart meter begins to run again.
The number of the autostarts allowed can be set using the "250.01 AutoStr" parameter (in standby
mode).
21.3 Handling Pending Errors During the Booting Procedure
During the booting procedure, all pending errors are generally confirmed without an entry being
made in the history (see menu "400# Failure/Event"). This way, an error that is still pending after the
booting procedure is re-entered or if the system detects that this error has stopped, it is entered as no
longer being present.
The Sunny Remote Control 1 displays:
• „!“ for set – the Sunny Backup 2200 has detected an error (again) and enters it in the list.
• "C" for clear – the cause of the error has been successfully corrected; the error is "no longer
present".
