Product Overview

The Woodward 9905-068 serves as a primary electronic governor for engine and turbine systems, specifically within the legendary 2301A product family. This 100% Brand New and Original module manages prime mover speed and facilitates proportional load sharing between multiple parallel-running generators. It detects speed via magnetic pickups (MPU) and drives proportional actuators to maintain a steady state, even during severe load transients. Engineered for rugged industrial environments, the 9905-068 provides the essential logic required for stable power generation, marine propulsion, and oil & gas compressor drives.

Engineering Advantages

Deterministic Analog Response: The 2301A architecture utilizes analog circuitry to provide instantaneous response to load changes. This prevents the computational lag sometimes found in older digital units, ensuring your engine reacts immediately to prevent overspeed or frequency dips.
Proportional Load Distribution: This module coordinates with other 2301A units through a dedicated load-sharing lines interface. It forces multiple generators to share the total kilowatt load proportionally to their individual capacities, preventing "load fighting" and ensuring grid stability.
Streamlined Field Commissioning: Front-panel potentiometers allow technicians to perform precise calibrations—including Gain, Reset, and Rated Speed—without specialized software or laptops. This manual interface simplifies setup in remote areas or high-security facilities where external data devices are restricted.
Superior Environmental Hardening: Woodward builds the 9905-068 to withstand the extreme thermal cycles and vibrations found in engine-mounted control cabinets. The wide -40 to +70 deg C operating range ensures reliable startup in arctic conditions and continuous operation in tropical or desert climates.

FAQs

Can the 9905-068 replace a digital 2301D controller?

While the 9905-068 performs similar functions, it is an analog module. Replacing a digital unit requires a review of the wiring and configuration logic. However, for systems that prioritize simplicity and analog speed of response, the 2301A remains the industry standard.

How do I troubleshoot a "Loss of Speed Signal" fault?

First, measure the AC voltage across the MPU inputs; it must exceed 1.5 Vrms during cranking. Inspect the MPU air gap and ensure the shielded cable remains grounded at only one end to prevent electrical noise interference.

Does this module support load sharing with third-party governors?

The 9905-068 uses Woodward’s standard load-sharing lines. To interface with non-Woodward controls, you may require a load-sharing gateway or interface module. It works seamlessly with other Woodward 2301A, 2301D, and 8272 series units.

What is the recommended maintenance for the potentiometers?

Once you reach the optimal setpoints, we recommend applying a small drop of calibration lacquer to the potentiometer screws. This prevents "creep" caused by the high-frequency vibration common in diesel engine applications.
