⚙️ Operation Specifications and Usage Methods
- Installation Preparation: Ensure all power sources to the electrical control cabinet are completely locked out. Mount the controller securely inside a protective industrial panel enclosure, ensuring proper shielding and grounding to prevent electromagnetic interference.
- Parameter Configuration: Integrate the controller with compatible Woodward load sharing and speed control modules. Set up internal transfer rates and base-loading references to manage smooth paralleling between the generator and the utility grid.
- Operational Control: Monitor soft load-in and soft load-out sequences via the control relays, ensuring precise power ramping and bumpless transfers during generator synchronization.
⚡ Startup and Shutdown Sequence
- Startup Sequence:
- Inspect all terminal wiring and confirm the 170 to 264 VAC input power supply lines are securely connected.
- Energize the AC input power source to activate the internal controller circuitry.
- Start the prime mover and bring the generator up to rated operating speed and voltage.
- Trigger the auxiliary breaker status to initiate the automatic soft load-in sequence, smoothly ramping active power to the preset target.
- Shutdown Sequence:
- Activate the unload contact to initiate the automated soft load-out process.
- Allow the internal controller to smoothly ramp down the generator power output toward zero.
- Open the generator circuit breaker to completely isolate the unit from the electrical bus.
- Shut down the prime mover according to standard operating procedures and remove input power once the system is offline.
