Procedure For Protective Relaying Programming
Note: Service Mode cannot be accessed when the engine control switch (ECS) is in the AUTO position.Note: An active shutdown fault is indicated by a FLASHING shutdown indicator. 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, the shutdown fault must no longer be occurring. The fault must be corrected. The ECS must be returned to the OFF/RESET position. If the jumper from terminal 6 to terminal 9 is not installed on the ECS, the GSC+ does 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 4" is showing on the lower display. For more information, see System Operation, "Password Entry OP3".
Press "CROLL UP" key two times. "OP5-1" is showing on the lower display.
Press "SELECT" key once. "P101" is showing. "P101" is followed by the value of the setpoint.
Press the "SCROLL UP" key or the "SCROLL DOWN" key. The next setpoint is showing with the setpoint value. Repeat this step until the desired setpoint is showing.
Press "SELECT" key. The value of the setpoint is flashing.
Press the "SCROLL UP" or the "SCROLL DOWN" key in order to adjust the value of the setpoint.Note: In order to rapidly scroll through a large range of values, press and hold the appropriate "SCROLL" key.
Press "ENTER" key. The value of the setpoint stops flashing. Repeat steps 4, 5, 6 and 7 until all the desired setpoints are adjusted.
Press "EXIT" key. "OP 1" is showing on the lower display.
Press "EXIT" key. The display returns to normal mode.
