To improve basic performance at no engine load:

Open the GAConfig Tool open the Engine Tuning menu, and at the PID Tuning block, perform the following:

a. Increase the Gain parameter by entering new parameter settings until instability develops. Gradually decrease the Gain until

stability returns. Decrease the adjustment one count further to ensure stable performance.

b. Increase Stability parameter on the until instability develops. Gradually decrease the Stability until stability returns. Decrease

the parameter by one to ensure it is stable. If there is no instability leave set at 50.

Set the DEADTIME to Low. If instability persists, change DEADTIME to High.

Once the engine is running at operating speed, with no load, use the GAConfig Tool to adjust the parameter settings to increase engine

stability. Each speed parameter, 1 through 3, has a separate Gain setting. The speed selection number and active Gain are shown in

the PID Tuning section.

Stability is achieved by balancing PID: Gain (P), Stability (I), and Deadtime (D).

Gain

(Proportional) changes the initial response of the governor. Increasing gain makes the engine more responsive to load

changes while decreasing gain makes it less responsive to load changes. Avoid engine instability due to high gain when adjusting

this parameter.

Stability

(Integral) changes the steady state response of the engine. Increasing stability allows the system to come to steady

state speed faster, while decreasing the stability results in a more gradual transition to steady state speed.

Deadtime

(Derivative) sets the transient response of the engine to high or low and affects the stability parameter during transient

load changes. Increasing deadtime decreases the percent of overshoot and settling time during a transient load change while

decreasing deadtime increases them. Note that setting Deadtime to High can cause random speed instability during steady state

since small speed

errors are amplified by this parameter.

Additional adjustments may be required after engine load is applied. Normally adjustments made at no load achieves satisfactory perfor

mance.
