Error Messages
Error messages indicate that there has been a change in system operation due to a
detected condition.
• You can retrieve the previous twenty Error messages by placing the unit in
Configure mode and then selecting View Last 20 PROsine Faults from the
Diagnostics menu.
• To clear an Error message, press the ESCAPE key.
• If the audible alarm is enabled, press ESCAPE twice. The first key press
deactivates the alarm and the second removes the message from the screen.
(The error is not cleared from the system, however.)
Some Error messages appear as
Internal nnnn
where nnnn is the number of the error.
If one of these errors causes the PROsine to shut down, attempt to restart the unit.
If the error occurs again, call Xantrex.
Other errors are listed in <Xref>Table 6-3. The text in the Error Message column
appears as the second line on the LCD; the first line displays PROsine Error.
