Programming Governor Gain Parameters
The governor gain parameters are set at the factory. The factory default settings are recommended for most applications. The default settings should allow the engine to respond quickly to transient load changes. The default settings should allow the engine to remain stable during all operating conditions. If the factory default setting does not provide satisfactory performance, the governor gain parameters can be adjusted.The parameters in Table 1 can be adjusted.
Table 1
Parameter Valid Range
Governor Gain Factor 0 - 1000
Governor Minimum Stability Factor 0 - 1000
Governor Maximum Stability Factor 0 - 1000 Note: No engineering units are associated with the numbers in table 1.Note: The range of the programmable setting is wide for flexibility. Do not expect to use the whole range. If the programmable setting is greater than the valid range, the system will revert to the factory default value.Do not perform this procedure until you read this information and you understand this information.Gain Explanations
Governor Gain Factor
The "Governor Gain Factor" is multiplied by the engine speed error. This value is derived by calculating the difference between the desired speed and the actual speed.
If the "Governor Gain Factor" value is too large, the engine speed can overshoot the desired speed.
If the "Governor Gain Factor" value is too small, the engine will accelerate slowly.Governor Minimum/Maximum Stability Factor
The "Governor Minimum Stability Factor" functions in order to eliminate steady state speed error. The "Governor Minimum Stability Factor" is used by the Electronic Control Module (ECM) when the steady state speed error is less than 20 rpm.The "Governor Maximum Stability Factor" functions in order to eliminate steady state speed error. The "Governor Maximum Stability Factor" is used by the ECM when the steady state speed error is increasing and the engine speed error is greater than 20 rpm.
If the "Governor Minimum Stability Factor" or the "Governor Maximum Stability Factor" is set too high, the ECM will provide additional fuel. The additional fuel will cause the engine speed to overshoot. The additional fuel will also cause the engine speed to oscillate.
If the "Governor Minimum Stability Factor" or the "Governor Maximum Stability Factor" is set too low, the engine will not achieve a steady state operation quickly.Tuning Procedure
Turn the Engine Control Switch (ECS) to the COOLDOWN/STOP position. Connect the Caterpillar Electronic Technician (ET). Enable the engine overspeed protection prior to the adjustment procedure. Adjusting governor gain parameters without engine overspeed protection can result in serious engine damage. Ensure that engine overspeed protection is ON. Engine overspeed is configured on the setup screen of "Service Monitoring System" in Cat ET.
Personal injury or death can result from engine overspeed.If the engine overspeeds, it can cause injury or parts damage. The engine should be equipped with a separate shutdown device, to protect against engine overspeed. Do not use for emergency shutdown.
Start the engine. Observe the control panel to ensure that the engine has reached the rated speed. The control panel will serve as the reference point for engine speed during this procedure.
