If an alarm has been configured with a shutdown alarm that has been enabled to self-
acknowledge, and has been configured as engine delayed the following scenario may
happen:
• The alarm shuts down the engine because of its alarm class. •
• Due to the engine stopping, all engine delayed alarms are ignored. •
• The alarm class is acknowledged automatically. •
• The alarm will self-acknowledge and clear the fault message that shut the engine •
down.
This prevents the fault from being analyzed. After a short delay, the engine will
restart.
• After the engine monitoring delay expires, the fault that originally shut down the •
engine will do so again.
This cycle will continue to repeat until corrected.
