7-Segment Error Codes
A 7-segment indicator appears on the following components;
refer to
. The 7-segment indicator provides codes to
indicate any present errors and their cause. When an error
occurs, the 7-segment will flash the error code. If multiple errors
are present, the 7-segment will flash the errors individually in
succession. If no errors are present, the 7-segment will show a
continuously looping figure-8.
