Manual 04127 ProAct III/IV Actuator/Driver
Woodward 1
Chapter 1.
General Information
The ProAct™ III and ProAct IV drivers convert either a 0–200 mA or 4–20 mA
control signal from a Woodward electronic control into a specific actuator
position.
The ProAct drivers require a separate electrical supply of 20–32 Vdc. The supply
must be capable of supplying a sustained 10 A and a peak 20 A for up to two
seconds for both the ProAct III and ProAct IV drivers.
The ProAct III actuator provides up to 14 J (10 ft-lb) of work to move the fuel
setting lever on the engine. The ProAct IV actuator provides up to 27 J (20 ft-lb)
of work. The actuators rotate 75 degrees, and they have position feedback.
Figures 1-1 through 1-3 show the control outline drawings, and Figure 1-4 is the
plant wiring diagram.
Engine stability and response are set by the controlling device, not by the
actuator and driver. Follow the instructions for the controlling device while setting
up the engine control system.
