Actuator Loop Feedback Response & Dynamic Stability
The internal proportional solenoid assembly executes dynamic rotational position adjustments between 35 deg and 40 deg to optimize the actuator loop feedback response during high-transient load steps. Driven directly by signals from Woodward 2301 or 2500 series control platforms, the hardware converts current inputs into proportional mechanical force, overcoming link stiction without dynamic overshoot. Internal thermal heat sink dissipation profiles efficiently channel internal heat away from the solenoid coil, maintaining force consistency and preventing thermal drift across the entire -40 to +85 deg C temperature envelope.
Frequently Asked Questions
Q: How does the proportional solenoid interface with existing Woodward 2301 or 2500 series control loops?
A: The solenoid coil receives a variable control current from the governor driver output, converting the current directly into proportional shaft rotation to regulate fuel rack positioning.
Q: What installation steps prevent mechanical linkage binding across the 35 to 40 deg travel range?
A: Technicians must align the actuator output lever and the engine fuel rack linkage in a single plane, checking manually for zero mechanical slop or binding before connecting the control link.
Field Installation Guidelines
Mount the unit rigidly to the engine bracket using high-tensile bolts to withstand operational vibration. Connect the 24 VDC power supply and governor output driver lines using twisted, shielded pair wiring. Electrical installers must ground the cable shield drain wire at the electronic governor bus bar only, preventing circulating ground current loops. Verify that the mechanical linkage operates freely through the full 35 deg to 40 deg rotation stroke prior to starting the engine.
