Procedure For Programming The Hourmeter
This procedure uses a new GSC with 0 hours as an example. The hourmeter in the new GSC will be set to a value of 1,234 hours. The value must be higher than the original value. Note: Service mode cannot be entered when the ECS is in the AUTO position. Note: Any active shutdown fault must be made inactive in order to access service mode. A FLASHING shutdown indicator means that a shutdown fault exists. To temporarily change a shutdown fault from an active shutdown fault to an inactive shutdown fault, turn the ECS to the OFF/RESET position. To permanently change a shutdown fault from an active shutdown fault to an inactive shutdown fault, the fault must not be occurring. Also, the ECS must be turned to the OFF/RESET position. If the jumper from terminal 6 to terminal 9 is not installed on the ECS, then the GSC will not power up in OFF/RESET and any active shutdown fault must be corrected before entering service mode.
Turn the ECS to the STOP position in order to shut down the engine. Enter service mode and enter the password. "OP 1" is showing on lower display. See Systems Operation, "Service Mode" for more information. See Systems Operation, "Password Entry OP3" for more information.
