Wherever a cross is placed under both Warning and
Alarm, this can mean that a warning precedes the
alarm. It can also mean that it is possible to program
whether a given fault is to result in a warning or an
alarm. After a trip, alarm and warning will flash, but if
the fault is removed, only alarm will flash. After a
reset, the FC motor will be ready to start operation
again.
