Under electronic control, speed and droop adjustments are made to the electronics. Most electronic controls provide features for isochronous load sharing between engines. The electronics must be able to function in droop mode for units that are paralleled with an infinite bus or to dissimilar governors.
The ballhead portion of the EGB governor/actuator can be operated isochronously or with droop for single-unit or parallel applications. A knob provides droop adjustment for the ballhead governor in parallel applications. The load-limit control knob is used to adjust the maximum output position of the governor/actuator.
