Page 13: Chapter 2. Description Of Operation
Introduction The ProAct™ control system functions by receiving a current signal from a Woodward electronic governor. The system then sends a pulse width modulated (PWM) current (–20 A to +20 A) signal to the actuator, modified by signals from a position feedback, velocity, and current sensor from the actuator (see Figure 2-1). -

ProAct III/IV Actuator/Driver Manual 04127 A 25-turn potentiometer (Offset) adjusts the actuator position with a minimum input signal from the speed control. A 25-turn pot (Span) adjusts how far the actuator travels when the speed control signal varies from minimum to maximum. This pot adjusts the maximum position of the actuator. -

Page 18: Actuator Bracket
Avoid pressure washing near the shaft seals. The ProAct III actuator weighs 11 kg (25 lbs), and the ProAct IV actuator weighs 19 kg (42 lbs). The bracket and attaching hardware must be designed to hold the weight and to withstand the vibration associated with engine mounting. -
Page 19: Linkage
Maximum actuator speed is 900 degrees per second in both the increase and decrease fuel directions. The ProAct III actuator's Mass Moment of Inertia (MMOI) is 0.027 in-lb-sec². The ProAct IV actuator's MMOI is 0.058 in-lb-sec². -

ProAct III/IV Actuator/Driver Manual 04127 ProAct III actuator stops are designed to absorb 1.1 J (10 in-lb) of kinetic energy with 3 degrees overtravel. ProAct IV actuator stops are designed to absorb 2.3 J (20 in-lb) of kinetic energy with 3 degrees of overtravel. If the actuator travel stops are used, the linkage must be designed to allow this 3 degree overrun. -
Page 21: Power Supply
Installations with severe electromagnetic interference (EMI) may require additional shielding precautions. Contact Woodward for more information. Failure to provide shielding can produce future conditions which are difficult to diagnose. Proper shielding at the time of installation is required to assure satisfactory operation of the ProAct control system. -
