Troubleshooting/Problem Solving

18 Troubleshooting/Problem Solving
In general the Sunny Island distinguishes between events and failures. These messages are shown
on the Sunny Remote Control 1 display.
Events describe state changes or transient states (e.g. generator connection).
•
Errors describe impermissible or only limitedly permissible states. This includes, warnings,
•
failures and errors. These normally require user interaction.

18.1 Error Confirmation

If there is an error or fault, the Sunny Island goes into standby.
Proceed as follows to acknowledge and remove an error message:
1. Remove the cause.
2. Acknowledge and confirm the error message by pressing the knob on the Sunny Remote
Control 1.
3. Start the Sunny Island again.

18.2 Handling Autostart

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 fault occurs when the autostart meter is at 0, the Sunny Island waits for 10 minutes and
then attempts to restart. The autostart counter starts again.
The number of autostarts allowed can be set using the "250.01 AutoStr" parameter (in standby
mode).

18.3 Handling Failures Present During Startup

During the booting procedure, all pending errors are generally confirmed without an entry being
made in the history (see. menu "400 Failure/Event). Any errors still present after that are entered
again after booting.
The Sunny Remote Control 1 shows:
• "Arrive" - the Sunny Island has recognized a fault (again) and has entered it in the list.
• "Clear" - the source of the fault has been cleared and the fault is "gone".

18.4 Display of Failures and Events

Every error and every event is labeled distinctively and placed according to the Parameter/
Measured value classification.
The message has four characters and is made up of one letter and three digits.
