10.4.1 Troubleshooting of alarms from supervisor µC
ANALOG INPUT (MDI/LED code = 96)
Cause:
This alarm occurs when the A/D conversion of the analog inputs returns
frozen values, on all the converted signals, for more than 400 ms. The goal of
this diagnosis is to detect a failure in the A/D converter or a problem in the
code flow that skips the refresh of the analog signal conversion.
Troubleshooting
If the problem occurs permanently it is necessary to replace the logic board.
