Procedure For Hourmeter Programming
A new GSC with 0 hours is used as an example in the following procedure. The example sets the hours to a value of 1234. If the value of the hours is increased, this procedure is valid. Note: Service Mode cannot be entered when the engine control switch (ECS) is in the AUTO position.Note: Any active shutdown fault (FLASHING shutdown indicator) 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/RESETposition. In order to permanently change a shutdown fault from an active shutdown fault to an inactive shutdown fault, the shutdown fault must not be present and the ECS must be turned to the OFF/RESET position. The GSC will not power up in the OFF/RESET position if the jumper from terminal 6 to terminal 9 is not installed on the ECS, 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 the lower display. See System Operations, "Password Entry OP3".
