Product Overview & Introduction
The WOODWARD 9905-096 is an advanced Automatic Generator Loading Control (AGLC) module designed for precision load management, sequencing, and regulation in industrial power generation systems. Engineered to work alongside load sharing and speed control modules, this device provides smooth loading and unloading of engine-generator sets when paralleling with the utility grid or other generators. Housed in a rugged metal chassis with high shock resistance, the unit ensures stable operation, optimized fuel efficiency, and seamless protection against system disturbances or overloads under varying load conditions.
Operational Specifications & Guidelines
Prior to installation, ensure that all electrical power sources, busbars, and control circuits are completely de-energized and locked out to prevent electrical shock or arc flash hazards. Mount the 9905-096 module securely within a protective, environmentally controlled industrial control cabinet or panel enclosure, allowing adequate clearance for heat dissipation and wiring access. Connect the AC input power supply (170–264 VAC, 50/60 Hz using at least 20AWG insulated wiring), control interfaces, and governor/actuator lines strictly in accordance with the manufacturer’s wiring schematics. Verify all terminal connections and ensure proper system grounding before restoring power. Calibrate response thresholds and adjustable ramp rates carefully to match the dynamic loading requirements of the prime mover system.
Startup & Shutdown Sequencing
To prevent system disturbances, out-of-phase transitions, or control loop instability, operators must strictly follow the defined startup and shutdown procedures.
- Startup Sequence:
- Verify all external wiring, potential inputs, control power connections, and safety interlocks are securely fastened.
- Energize the system control power supply to the WOODWARD 9905-096 module (activated automatically upon the closure of circuit breaker auxiliary contacts) and perform a complete self-test.
- Start the prime mover and allow it to reach rated nominal speed and thermal stability under governor control.
- Enable the AGLC module to monitor system potential and compare the oncoming generator against local bus parameters.
- Engage automatic loading control, allowing the unit to execute smooth, bumpless soft-loading synchronization without voltage or frequency disturbances.
- Shutdown Sequence:
- Gradually initiate soft-unloading via the control module to transfer active electrical load away from the generator set back to the main grid or companion units until minimum baseline load is achieved.
- Open the main generator circuit breaker manually or via system command to isolate the unit electrically from the busbar.
- Initiate the standard prime mover cool-down cycle at idle speed for the required duration.
- Issue the stop command to shut down the engine or turbine completely.
- De-energize the auxiliary control power to the loading control module only after the prime mover has come to a complete standstill.
Frequently Asked Questions (Q&A)
- Q1: What is the primary function of the WOODWARD 9905-096 AGLC module?
- A1: The unit automatically manages generator loading and unloading, provides bumpless soft-loading transitions during parallel operations, and handles base-load control or peak-shaving strategies.
- Q2: What are the input voltage and power consumption specifications for this model?
- A2: The module operates within an AC input voltage range of 170–264 VAC (supporting 50 or 60 Hz frequencies) and has a low typical power consumption of 5 VA.
- Q3: Can the 9905-096 draw its operating power directly from the local electrical bus?
- A3: Yes, drawing input power directly from the local bus is acceptable for this module, provided that power supply wiring meets minimum gauge (20AWG) and insulation standards.
