⚙️ Operation Specifications and Usage Methods

• Installation Preparation: Ensure all power sources to the electrical switchgear panel are completely locked out. Mount the SPM-D21/PSVX unit securely into the panel door cutout using standard mounting hardware, ensuring proper front-panel sealing against environmental hazards.
• Parameter Configuration: Connect a configuration PC to the service port using Woodward configuration software to set up dual-breaker control logic, potential transformer (PT) ratios, PID governor dynamics, and scaling parameters for the analog and PWM outputs.
• Operational Control: Monitor real-time synchronization states, bus/generator voltages, and multi-breaker operations through the integrated graphical display while the module manages automated power transfers and load control.

⚡ Startup and Shutdown Sequence

• Startup Sequence:
  1. Inspect all terminal wiring for the dual breaker auxiliary contacts, potential transformers, and 12/24 VDC power supply lines.
  2. Energize the control power supply and verify that the module initializes successfully with zero fault flags on the screen.
  3. Start the prime mover and bring the generator up to rated operating speed and nominal voltage.
  4. Engage the SPM-D21/PSVX synchronization mode to execute automatic frequency, phase angle, and voltage matching before commanding the respective circuit breaker to close.
• Shutdown Sequence:
  1. Initiate active load reduction via control commands or remote signals to ramp down generator output smoothly.
  2. Open the active generator circuit breakers through the module to isolate the unit from the electrical bus.
  3. Shut down the prime mover engine or turbine according to standard operational safety protocols.
  4. De-energize the auxiliary control power supply and measuring input lines once the system is fully offline.
