⚙️ Operation Specifications and Usage Methods
- Installation Preparation: Ensure all power sources to the electrical control cabinet are completely locked out and tagged out. Mount the controller securely inside an industrial panel enclosure, ensuring proper shielding and grounding to prevent electromagnetic interference.
- Parameter Configuration: Integrate the module with Woodward load sharing and speed control systems (such as the 2301, EPG, or EasyGen-associated architectures). Configure the input power jumpers for either 115 VAC or 230 VAC operation.
- Operational Control: Utilized to regulate and adjust the electrical load assumed by commercial generator sets, providing reliable soft loading and soft unloading capabilities during paralleling operations.
⚡ Startup and Shutdown Sequence
- Startup Sequence:
- Inspect all terminal wiring, confirming that the 115/230 VAC input power lines and paralleling lines are securely connected.
- Energize the AC input power source to activate the internal control circuitry.
- Start the prime mover and bring the generator up to rated operating speed and nominal voltage.
- Engage the system to initiate the automatic or semi-automatic soft loading sequence, allowing the controller to smoothly ramp up active power to the target set point.
- Shutdown Sequence:
- Initiate the soft unload routine manually or via control commands to safely shed active power.
- Allow the controller to ramp down the generator’s electrical load output toward zero.
- Open the main generator circuit breaker to isolate the unit from the shared electrical bus.
- Shut down the prime mover according to standard operating safety protocols and remove input power once offline.
