⚙️ Operation Specifications and Usage Methods

• Installation Preparation: Ensure all power sources to the electrical switchgear panel are completely locked out. Mount the compact SPM-D11 unit securely into a standard panel cutout using the integrated retention clips, ensuring proper front-face environmental sealing.
• Parameter Configuration: Connect a configuration PC to the communication port using Woodward software tools to configure generator voltage inputs (100 VAC measuring inputs), phase matching parameters, frequency thresholds, and analog/discrete bias output levels.
• Operational Control: Monitor real-time system diagnostics, true RMS power calculations, and synchronization statuses via the integrated 2-line liquid crystal display while the unit manages automatic breaker closing and load sharing.

⚡ Startup and Shutdown Sequence

• Startup Sequence:
  1. Inspect all terminal wiring for the generator potential transformers, busbar inputs, and auxiliary power connections.
  2. Energize the 12/24 VDC control power supply and verify that the 2-line LCD screen initializes successfully without error flags.
  3. Start the prime mover and bring the generator up to rated speed and nominal voltage.
  4. Enable the SPM-D11 synchronization mode to execute automatic frequency, phase, and voltage matching before issuing the breaker close command.
• Shutdown Sequence:
  1. Initiate soft unloading via control commands to ramp down active generator power output smoothly.
  2. Open the generator circuit breaker to isolate the unit from the shared electrical busbar.
  3. Shut down the prime mover engine or turbine according to standard mechanical safety protocols.
  4. De-energize the auxiliary control power supply and measuring input lines once the system is fully offline.
