Page 6: Electrostatic Discharge Awareness
Do not touch the components or conductors on a printed circuit board with your hands or with conductive devices. To prevent damage to electronic components caused by improper handling, read and observe the precautions in Woodward manual 82715 , Guide for Handling and Protection of Electronic Controls, Printed Circuit Boards, and Modules. -
Page 7: Chapter 1. General Information
General Information Introduction The ProAct II driver converts either a 0–200 mA, 4–20 mA, 4–13 mA, 11–20 mA, PWM, or a 0–5 V control signal from a Woodward electronic control into a specific actuator position. The driver provides a feedback of 0.5–4.5 V corresponding to actuator position. -

Page 12: Chapter 2. Installation
The actuators are designed for installation on the engine. The actuators will generate heat, especially when stalled or during other conditions requiring maximum torque output. Maximum operating temperature for the ProAct II actuator is 100 °C (212 °F). The installer must consider the heat conductivity of the installation bracket, and the operating temperature of the ultimate heat sink to which the bracket will be attached. - Page 13 Moment of Inertia (MMOI, with inertia disc applied) is 3.67*10 in-lb- sec². ProAct II actuator stops are designed to absorb 1.1 J (10 in-lbs) of kinetic energy with 3 degrees overtravel. If the actuator travel stops are used, the linkage must be designed to allow this 3 degree overrun.

Page 14: Actuator Bracket
Avoid pressure washing near the shaft seals. The ProAct II actuator weighs 6.9 kg (15.23 lbs). The bracket and attaching hardware must be designed to hold the weight and to withstand the vibration associated with engine mounting. -

(2 inches). The other end of the shields must be left open and insulated from any other conductor. DO NOT run shielded signal wires along with other wires carrying large currents. See Woodward application note 50532, Interference Control in Electronic Governing Systems, for more information. -
Page 16: Power Supply
ProAct II Actuator/Driver Manual 04176 Power Supply Power supply output must be low impedance (for example, directly from batteries). Run an insulated wire directly from the positive (+) battery terminal to the fuse and the switch as shown in Figure 2-5, then from the switch to the correct connection on the driver (see Figure 1-4). -

If the characteristic falls outside the tolerance... -
Page 19: Actuator Travel
Manual 04176 ProAct II Actuator/Driver The adjustment of the system position feedback potentiometers does not affect the positioning of the actuator relative to the position input signal, or the response of the actuator to the position input signal. Reconnect the actuator drive wires. -
Page 20: Chapter 3. Description Of Operation
Description of Operation The ProAct control system functions by receiving a position command signal from a Woodward electronic governor. The system then sends a pulse width modulated current (–12 A to +12 A) signal to the actuator, modified by signals from a position feedback, velocity, and current sensor from the actuator (Figure 3-1). -
Page 21: Actuator Position Signal
Manual 04176 ProAct II Actuator/Driver A 25-turn pot (Position Command Offset) adjusts the offset of the actuator travel when the speed control signal varies from minimum to maximum. A 25-turn pot (System Position Feedback Gain) adjusts the system position feedback gain as the actuator varies from minimum to maximum. -
Page 22: Chapter 4. Troubleshooting
ProAct II Actuator/Driver Manual 04176 Chapter 4. Troubleshooting Improper engine operation is often the result of factors other than governor operation. This chapter gives tips about engine problems which can resemble governor problems. Make sure the engine is operating correctly before making any changes in the governor. -
Page 23: Chapter 5. Technical Specifications
Technical Specifications Power Supply The power supply for the ProAct II driver is configured to operate from 20 to 32 Vdc. The minimum current level to be provided by the system will be 6 A dc and 12 A dc for up to two seconds. -
