Actuator Loop Feedback Response and Engine Speed Control

The Woodward LR20949 processes engine speed and load inputs to deliver high-speed actuator loop feedback response. Communication across integrated CANbus and Modbus interfaces allows the module to exchange real-time diagnostic and operational data with supervisory control networks. Operating over a broad supply range of 12-24 VDC and temperatures from -40 to +85 deg C, the internal control algorithms dynamically adjust actuator outputs to optimize engine stability under variable load conditions.

Frequently Asked Questions

Q: What is the operating input voltage range for the Woodward LR20949 control module?

A: The module operates on an auxiliary DC power supply ranging from 12 VDC to 24 VDC.

Q: Which communication protocols are supported on the LR20949 module?

A: The hardware includes onboard interfaces for CANbus and Modbus communication protocols.

Q: What is the certified operating temperature range for this engine control unit?

A: The module is specified for full industrial operation between -40 deg C and +85 deg C.

Field Installation Guidelines

  • Mount the control module in a cabinet or enclosure designed to isolate the hardware from excessive vibration and direct heat sources.
  • Verify input power wiring polarity and confirm supply voltage remains within the allowed 12-24 VDC range prior to powering up.
  • Use shielded twisted-pair cabling for all CANbus and Modbus communication lines, grounding cable shields at a single point to prevent ground loops.
  • Keep low-voltage control and communication wiring routed separately from high-voltage AC cables and heavy inductive load wiring.
