Configured for speed control and load management in industrial power generation networks, the Woodward LR20949 (LR20949 Engine Control Module) provides direct physical/electrical execution. This electronic hardware unit interfaces directly with prime movers to process system parameters and manage engine operational profiles.

Hardware Specifications

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.

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.
