In the event of a Hard Failure, the control board will shutdown the HPA for 30
seconds and then turns on the HPA to check for a repeated Hard Fail occurrence. If
the next two occurrences sense a Hard Fail, the control boards will shutdown the
HPA for 1 hour (total of three consecutive hard fails). After 1 hour, the HPA will
automatically come back alive and the control board will check if the Hard Fail alarm
has cleared or not. If it has not, the same process will continue as mentioned above.
