Note: The engine may be running or the engine may be stopped while the operator is viewing the setpoints.Note: Service mode cannot be entered when the engine control switch (ECS) is in the AUTO position.Note: An active shutdown fault must be made inactive in order to access service mode. To temporarily change a shutdown fault from an active shutdown fault to an inactive shutdown fault, turn the ECS to the OFF/RESET position. The shutdown fault must be corrected, and the ECS must be turned to the OFF/RESET position in order to permanently change a shutdown fault from an active shutdown fault to an inactive shutdown fault.
