GOVERNOR GP-WOODWARD 3N4114 - Caterpillar

electronic engine control system for this engine utilizes the Generator Set Control+ (GSC+) for engine monitoring and engine control. The GSC+ provides engine gauges for monitoring engine operating conditions. The Engine Meter key that is found in the display area of the GSC+ is used by the operator to scroll through the engine operating conditions. Alarm indicators on the GSC+ are used for annunciating engine events. If an engine shutdown, or other action is initiated by the control panel, the alarm indicator will provide the operator with information that is related to the cause of the action.Note: For information about the Generator Set Control+ (GSC+), refer to Operation and Maintenance Manual, SEBU7050, "SR4B Generators And Control Panels". Gauges are used to provide the operator with engine information that is necessary to monitor engine performance. Determine the normal operating range by observing gauge readings during a variety of operating conditions. Extend your observations over a long period in order to establish a reference point. Ensure that the gauges are properly maintained and that the gauges are in good condition.Noticeable changes in gauge readings indicate potential gauge or engine problems. Problems may also be indicated by gauge readings that abruptly change, even though the readings remain within the normal operating range. Determine and correct the cause of any significant change in the readings. Consult your Caterpillar dealer for assistance.Your engine may not have the same gauges or all of the gauges that are indicated below.
If no oil pressure is indicated, STOP the engine. The engine will be damaged from operating without oil pressure.
Engine Oil Pressure - This gauge indicates the pressure of the engine lubrication system. Engine oil pressure will be highest after a cold engine has been started. The engine oil pressure will decrease as the engine warms up. The typical range of engine oil pressure at rated engine speed is 275 to 606 kPa (40 to 88 psi). A lower oil pressure is normal at a lower engine speed.If the load is stable and the gauge reading changes suddenly, perform the following procedure:
Remove the load.
Reduce the engine speed to low idle.
Check the oil level or determine the cause of the change. If the engine oil pressure drops below a preset value, the Low Oil Pressure indicator on the control panel will turn ON and the engine will shut down. The GSC+ and the Electronic Control Module (ECM) will log the event in internal memory.
System Battery Voltage - This gauge indicates the current battery voltage that is being measured by the ECM. A diagnostic code will be generated by the ECM if the engine experiences a high voltage condition or a low voltage condition. Engine operation may be unpredictable if a system voltage that is within an acceptable range is not maintained.
Exhaust Temperature - This gauge indicates the engine exhaust temperature. Maximum exhaust temperature is approximately 575°C (1065°F).
Engine Oil Temperature - This gauge indicates the temperature of the engine oil. The GSC+ may be programmed to shut down the
