8. Diagnostics
8.1. Diagnostics menu
The diagnostics menu contains the following functions:
Error Log
Diag. values
Diag. limits
8.2. Error table
In the diagnostics menu, select "1=Error table". If the
self-diagnostics system has detected no errors, the
display reads "NO ERRORS". If errors have been de-
tected, the first line of the display shows the timestamp
when the error occurred, the second line shows when
it ended, and the error type is shown on the third line.
If the error is still on, the ending timestamp is shown
as '--'. The message "Shutdown" instead of the error
ending stamp indicates that operating power was
switched off when the error was still on. If the error is
still on when the power is connected on again, it will
be stored in the error table as a new error. The table
contains the 10 most recent errors.
