ANALOG
INPUT
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.
If the problem occurs permanently
it is necessary to replace the logic
board.

HW FAULT
EV.
At start-up, the hardware circuit dedicated
to enable and disable the EV drivers is
found to be faulty. The hexadecimal value
“XX” facilitates EP technicians debugging
the problem.
This type of fault is not related to
external components. Replace the
logic board.
