Procedure For Overspeed Verification
Note: Service mode cannot be accessed when the engine control switch (ECS) is in the AUTO position.
Start and run the engine at rated speed. Enter service mode and enter the password. "OP 9" is showing on the lower display. See System Operation, "Password Entry OP3".
Press the "SELECT" key. The value of the overspeed setpoint "P010" is showing on the upper display. The default value for P010 is 2120. "SC1" is showing on the lower display. "SC1" is followed with the present engine speed value.
Press "SELECT" key. The setpoint value is flashing on the upper display.
Decrease the setpoint value by pressing the "SCROLL DOWN" key. The default setpoint value is 2120. The default value is flashing on the upper display. The setpoint value decreases by 10 rpm with each press of the scroll down key. Press the "SCROLL DOWN" key until the setpoint value is past the present engine speed value that is showing on the display. When the setpoint value is less than the present engine speed value, the engine will shut down. The engine overspeed indicator will flash. The GSC+ will no longer be in the service mode.Procedure For Oil Pressure Verification
Note: Service mode cannot be entered when the ECS is in the AUTO position.
Start the engine and run the engine at rated speed. Enter service mode and enter the password. "OP 9" is showing on the lower display. See System Operation, "Password Entry OP3" for more information about entering the password.
Press "SELECT" key. The value of the overspeed setpoint P010 is showing on the upper display. The default value for P010 is 2120. "SC1" is showing on the lower display. The present engine speed value is then shown on the display.
Press the "SCROLL UP" key once. The value of the P013 setpoint for low oil pressure shutdown at rated speed is showing on the upper display. 205 kPa (30 psi) is the default value. The present oil pressure value is shown on the display.
Press "SELECT" key. The setpoint value is flashing on the upper display.
The setpoint value that is flashing on the upper display is increased by pressing the "SCROLL UP" key. With each press of the "SCROLL UP" key, the setpoint value increases by five. Press the "SCROLL UP" key until the setpoint value is past the present value that is showing on the lower display. When the setpoint value is greater than the present oil pressure value, the engine shuts down. The indicator for low oil pressure should be flashing. The GSC+ should not be in service mode.Procedure For High Water Temperature Verification
Note: Service mode cannot be entered when the ECS is in the AUTO position.
Start the engine and run the engine at rated speed. Enter service mode and enter the password. "OP 9" is showing on the lower display. See System Operation, "Password Entry OP3".
Press "SELECT" key. The value of overspeed setpoint "P010" is showing on the upper display. The default value of the overspeed setpoint is 2120. "SC1" is showing on the lower display. "SC1" is followed with the present engine speed value.
Press the "SCROLL UP" key two times. The value of the P015 setpoint for high water temperature shutdown is showing on the upper display. The default value for setpoint P015 is 107°C (225°F). "P015" is showing on the upper display. "SC3" is then shown on the lower display which is followed by the present coolant temperature value.
Press the "SELECT" key. The setpoint value is flashing on the upper display.
The setpoint value that is flashing on the upper display is decreased by pressing the "SCROLL DOWN" key. With each press of the "SCROLL DOWN" key, the setpoint value decreases by five degrees. Continue pressing the "SCROLL DOWN" key until the setpoint value decreases past the present coolant temperature value that is showing on the lower display. The engine shuts down and the high water temperature indicator begins flashing when the setpoint value is less than the present coolant temperature value. The GSC+ is no longer in service mode.
