Actuator Loop Feedback & Harmonic Distortion Suppression

The 2301A module drives hydraulic or electric fuel actuators by converting speed errors and load sharing signals into a calibrated 0 to 200 mA output current. Actuator loop feedback response directly determines dynamic governing performance under rapid step-load transients. Integrated signal conditioning limits high-frequency noise interference, providing harmonic distortion suppression across the magnetic pickup input circuit to preserve steady-state frequency control.

Frequently Asked Questions

  • Q: What cable type should be used for connecting the magnetic speed sensor?
  • A: Magnetic pickup connections require two-conductor twisted-shielded cable to maintain signal integrity, with the cable shield grounded solely at the control unit chassis.
  • Q: How is power supply isolation handled for the 20 to 40 VDC input terminals?
  • A: Operating power must be routed through dedicated fused conductors, keeping DC negative isolated from earth ground unless explicitly required by local system wiring schematics.
  • Q: What is the function of the 0 to 200 mA current output interface?
  • A: The 0 to 200 mA current loop interfaces directly with Woodward fluid/fuel actuator coils to translate electronic speed correction commands into physical valve positioning.

Field Installation Guidelines

  • Mount the unit vertically inside an enclosure using all four mounting holes to maintain stable thermal dissipation across the baseplate.
  • Route signal lines, magnetic pickup wiring, and load-sharing bus cables in separate grounded metallic conduits away from heavy AC power leads.
  • Ensure shield drain wires are connected strictly to the designated chassis terminal to avoid creating unwanted ground potential loops.
  • Verify input voltage remains strictly within the 20 to 40 VDC range under both static and dynamic generator operating states.
