Configured for load sharing and speed control in prime mover applications, the Woodward 8273-1011 (2301E Speed Controller) provides direct physical/electrical execution. The microprocessor-based digital control unit manages diesel engines, gas engines, or steam turbines by processing speed sensor inputs and generating precise actuator output signals. It incorporates software-configurable control modes including isochronous speed control, droop speed control, and auxiliary load sharing over dedicated analog or network interfaces.

Hardware Specifications

Actuator Loop Feedback Response & Speed Regulation

The Woodward 8273-1011 processes high-resolution pulse inputs from magnetic pickups (MPUs) to monitor prime mover rotational velocity. Its internal PID control algorithm dynamically corrects speed deviations, optimizing actuator loop feedback response to drive electric or electro-hydraulic actuators. The digital architecture ensures deterministic closed-loop execution, minimizing overshoot and settling time during abrupt load acceptance or rejection sequences.

Frequently Asked Questions

Q: How is the Woodward 8273-1011 speed controller configured for field operation?

A: Parameter setup, I/O calibration, and dynamic PID tuning are executed via serial communication using the Woodward Control Assistant or ToolKit service tool on a PC.

Q: What actuator interface options are supported by the 2301E hardware?

A: The module provides configurable analog outputs designed to drive standard Woodward drivers and electro-hydraulic actuators across selectable current or voltage ranges.

Q: How does the module handle load sharing in multi-generator set applications?

A: The unit features dedicated analog load sharing lines and software settings to maintain balanced active power distribution across multiple prime movers operating in parallel.

Field Installation Guidelines

• Ensure all power sources and fuel supply valves are isolated before terminating field wiring to the controller.
• Connect magnetic pickup (MPU) speed sensors using twisted shielded-pair cable, grounding the shield at the controller end only to prevent noise interference.
• Verify that actuator signal lines are routed in grounded conduit separate from high-voltage AC power cables.
• Securely mount the chassis to a vertical flat surface using panel mounting hardware with full thread engagement.
• Calibrate the minimum and maximum actuator position limits in software prior to starting the prime mover for the first time.
