Engine/Generator Programming OP5

Usage:

OP5 is the option for programming the engine/generator setpoints. The engine/generator setpoints affect the proper operation and serviceability of the engine, and the accuracy of information shown on the display. The setpoints are programmed in the GSC at the factory.

The setpoints may require changing when the GSC is moved from one engine to another engine. Customer requirements and moving the GSC from one engine to another engine may require changes in the setpoints. The setpoints that are stored in the GSC must match the specified setpoints of the particular generator set. The setpoints are P01 to P24 and the setpoints are programmable. The setpoints are described in Table 1.

Procedure For Engine/Generator Programming

Note: Service Mode cannot be entered when the ECS is in the AUTO position.

Note: Any active shutdown fault (any shutdown indicator FLASHING) 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 be no longer occurring. The fault must be corrected and 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, the GSC does not power up in the OFF/RESET position 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 Systems Operation, "Procedure To Enter The Password" that is located within the topic Password Entry OP3 for more information.

Press "SCROLL UP" key again. OP5 is showing on the lower display.

Press "SELECT" key again. P01 is showing on the display. P01 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 value of the setpoint. Repeat this step until the desired setpoint is showing.

Press the "SELECT" key. The value of the setpoint is flashing.

Press the "SCROLL UP" key or "SCROLL DOWN" key in order to adjust the value of the setpoint.
Note: Press and hold the appropriate "SCROLL" key in order to rapidly scroll through a large range of values.

Press the "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 will return to the normal mode.

^( 1 )	The setpoints that are stored or the setpoints that are being programmed must match the specified setpoints of the particular generator set.
^( 2 )	When oil pressure drops to within 34 kPA (5 psi)of the "P13" or "P14"setpoint, a low oil pressure alarm is issued by the GSC and the optional alarm module (with the exception of the NFPA 99 RAN).
^( 3 )	When coolant temperature rises to within 6°C (11°F)of the "P15 "setpoint, a high water temperature alarm is issued by the GSC and the optional alarm module (with the exception of the NFPA 99 RAN).
^( 4 )	The values other than the default (700V) are for switchgear applications and require the use of external potential transformers and the removal of the AC voltage range jumper located in the relay module. See the topic AC Voltage Range Selection in the Testing And Adjusting section.
^( 6 )	The P24 setpoint only functions when the P23 setpoint is set to 1 (gas engine).
