All of these actuators require adjustable compensation to provide stability of operation. Because the Woodward designation of most integrating actuators is shown with a “C,” the term “compensated” is used interchangeably with “integrated” in the discussion of test equipment for actuators. - Page 9 (full clockwise position) Connection Select the correct cable assembly from Figure 1-3. Connect the actuator to the actuator tester with the correct cable assembly. Connect the actuator tester to 115 VAC supply and turn power ON. Woodward...
