GSC300 Product Number Identification The GSC300 series product numbering scheme provides significant information pertaining to a specific model. The Product Number Identification Table (see Table 1) provides the required interpretation information. An example is offered to initially simplify the process. A product number GSC300-X-XX-XX would consist of a combination of information from the following table.
WIRING INSTALLATION GUIDELINES Danger: Never work on the engine while its power is on. This controller does not generate a warning signal prior to automatic engine start. Warning signs should be placed on engine equipment indicating this important safety measure. INSTRUCTIONS Following these instructions will help avoid common installation problems during wiring and setup. • Battery must be disconnected before any wiring connections are made.
WIRING GUIDELINES 1. DO NOT use wire smaller than 18 AWG. 2. IMPORTANT: The connections supplying DC power to the GSC300 panel should preferably run directly from the battery posts with no splices or other connections. Avoid using chassis (aluminum or iron engine parts), as return conductor for battery negative voltage. Copper wiring is recommended. Failure to follow the above may result in erratic operation due to large voltage drops across wiring connections.
GSC300 12/24VDC SYSTEM OPERATION The GSC300 controller is designed to operate in either 12 or 24 VDC system voltages. When operating in 12VDC systems the fuel, crank and preheat/ets relays need to be the proper 12VDC relay type. When operating in 24VDC systems these relays need to be the proper 24VDC relay type. Contact the factory if relays are required.

CONTROLLER OVERVIEW The GSC300 Features the Following Functions: 1. Controller Programming Adjustability 2. General Fault Conditions 3. Not In Auto 4. Low Battery Voltage Alarm 5. Oil Pressure Input 6. Coolant Temperature Input 7. Fuel Level/Auxiliary Input 8. Speed Signal Sensing 9. Adjustable Input Programming 10.
3: NOT IN AUTO: When the controller is in the OFF Mode, the NOT IN AUTO LED will illuminate and the NOT IN AUTO Output will close to +Vbatt, indicating the controller is not in the AUTO Mode. The LCD display will read “OFF”, however the backlight on the LCD display will not be ON. NOTE: + Battery must be permanently connected to the AUTO terminal for the NOT IN AUTO condition and LED indications to function properly.

Programming The GSC300 Settings Using the Front Panel Interface: The following table shows the LED’s that correspond to the various settings of the various parameters. To enter the controller into Program Mode, you need to turn the small switch at the bottom edge of the controller to the program position. This Mode Switch can be set using a ballpoint pen or such to allow the controller to be put into Program Mode.
Numbering Of LED’s and Location of Mode Switch Programming Using the PC Interface The GSC300 can also be programmed using the PC interface. Detailed instructions on the PC interface are included with the GSC300 Configurator software. A sample interface screen is illustrated on the following page.

TROUBLESHOOTING GUIDELINES TROUBLE POSSIBLE CAUSE SUGGESTED ACTION Unit does not operate when powered to test mode Power leads to unit are reversed Confirm correct wiring for ground and +bat, and re-attempt testing. Run wire directly from battery - to the ground terminal #11on controller unit. Check to ensure that the speed sensing wires of the controller are connected to the generator output.
TECHNICAL NOTES ON FREQUENTLY ASKED QUESTIONS 1. Controller Memory Clear Time The GSC300 needs 10 seconds for its memory to clear. When the power to the controller is turned off and then back on again without waiting a few seconds to clear the memory, a loss of speed will be indicated by the GSC300 because the controller remains in run mode and senses that the generator has stopped. This would be indicated by a Flashing Overspeed LED.
