- •Fuel supply pressure drops below approximately 5 in. water column
Suggested Actions
- 1Identify and address the cause of the E-stop circuit actuation.
- 2Address the specific operating fault (e.g., low oil pressure, high temperature, overspeed, overcrank, under voltage, over voltage).
- 3Investigate and rectify the cause of low engine oil pressure.
- 4The controller initiates a 10-second hold-off timer before automatic engine shutdown.
- 5Address the cause of low fuel supply pressure.
