 Diagnose the high speed part and then the low speed part.
From the alarm signal stream, the alarm of the high speed signal often causes the alarm of
the low speed signal. Therefore, remove the fault of the high speed part first.
 Analyze the alarm of high level and then that of low level.
Analyze the alarm of high level, such as critical alarm or major alarm. Then, analyze the
alarm of low level, such as minor alarm or warning alarm.
