FAQ
Q: What is the Woodward 9905-377?
A: The 9905-377 is a Woodward 2301A Load Sharing and Speed Control module. It combines electronic engine-speed regulation with load-sharing functions for generator systems operating in parallel.
Q: What is the main function of the 9905-377?
A: The controller receives engine-speed feedback, compares it with the required operating speed and controls the connected actuator. In multi-generator systems, it also supports balanced load distribution between generating units.
Q: What type of speed sensor does the 9905-377 use?
A: The controller normally receives speed feedback from a magnetic pickup (MPU). The pickup signal provides the frequency information required for accurate engine-speed measurement.
Q: What power supply is required?
A: The 9905-377 is designed for a nominal 24 VDC control system, with a commonly specified operating range of approximately 18–32 VDC.
Q: Can the 9905-377 operate in both droop and isochronous modes?
A: Yes. The 2301A controller supports both droop and isochronous control. Droop is commonly used for load sharing between parallel generators, while isochronous operation is suited to applications requiring constant engine speed.
Q: What type of engines can be controlled by the 9905-377?
A: The controller is commonly used with compatible diesel and gas engines. The actuator, magnetic pickup and engine fuel-control arrangement must be matched to the specific application.
Q: Is the 9905-377 suitable for parallel generator operation?
A: Yes. Load-sharing capability makes it suitable for generator sets operating in parallel, where coordinated speed and load control is required to distribute generator output.
Q: What are the dimensions and weight of the 9905-377?
A: Commonly referenced dimensions are approximately 241 × 165 × 64 mm, with a weight of about 1.85 kg. Mechanical dimensions can vary by hardware revision, so the actual unit should be checked against the applicable installation documentation before panel fabrication.
