Some alarms might not be reset before the cause that generated it has been
removed. For example, an alarm due to an error in the tripping circuit (coil
supervision) cannot be reset before the tripping coil is replaced. Whereas an
alarm generated by a trip of a protection function is normally reset with this
procedure.
