5.3 7-Segment Error Codes
A 7-segment indicator appears on the following components; refer to
Figure 7
. 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.
