Functional Description
The WOODWARD 8440-2082 is a microprocessor-based digital governor controller designed for precise speed control of diesel, gas, and steam engines/turbines. It offers advanced control algorithms for optimal engine performance, including proportional-integral-derivative (PID) control, load sharing, and droop compensation.

This controller features user-configurable parameters via front-panel keypad or PC software, real-time monitoring of engine speed and system status, and built-in fault diagnostics for quick troubleshooting. It is widely used in power generation, marine, and industrial applications requiring reliable and accurate speed regulation.
Installation Notes
  • Mount the controller in a dry, vibration-damped location away from high-voltage equipment and electromagnetic interference.
  • Use shielded cables for all analog signals to minimize noise and ensure accurate measurements.
  • Verify all wiring connections against the wiring diagram before applying power to prevent damage.
  • Calibrate the speed sensor and control outputs after installation and before system commissioning.
  • Ensure proper grounding (PE) connection to meet safety standards and reduce electrical noise.
  • Follow Woodward’s recommended maintenance schedule for periodic inspection and calibration.
