If a discrete input has been configured with a shut-down alarm that has been enabled to
self-acknowledge, and has been configured as engine delayed the following scenario may
happen:
• The discrete input 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.
