Each 723PLUS controller requires 40W of power. It may produce a nominal current impact 7A. Allows the input voltage range 18-40Vdc. Input voltage switch on / off command signals such as acceleration and deceleration of the electrical control. Each switch signal requires at rated voltage 24Vdc 10mA of current. These can be used to drive the low-voltage power supply instruction signal. Torsional Vibration filter described in the manual included in the 723PLUS control module. In order to maximize the filter is to reduce the elastic coupling torsional vibration effects. And provides extremely smooth and stable control, and the engine can be made to match the dynamic control and not cause imbalance to compensate for torsional vibration coupler. If you can eliminate the influence of torsional vibration coupler, Woodward, couplers life will be longer. If there is an unacceptably high level of torsional vibration occurs, the controller will alarm and limit the fuel supply. Most PG governors head by a ring bolt (lug) hoisting, Woodward agents, the ring head bolts (lug) is mounted in the center of a governor cover 0.375-16 (inch) hole. PG-200, PG-300, PG-500 governor must use derrick hoisting grommet. Some PG governor detachable cap is also required derrick hoisting grommet. Between the governor and the accessory mount to use a spacer. Recommend shim 0.032 inches thick (0.81mm). Spacer used to fill not fit between the governor base and mount between the oil between the driving part to avoid the governor an engine leak.
