⚙️ Operation Specifications and Usage Methods
- Installation Preparation: Ensure all power sources to the switchgear and control cabinet are completely locked out. Mount the robust dual-display unit securely onto a vertical panel cutout, utilizing the built-in gasket to maintain IP54 environmental sealing on the front face.
- Parameter Configuration: Utilize the local dual-display keypad interface or connect via communication ports using Woodward configuration tools to define multi-unit sequencing parameters (up to 16 units), bus voltage references, and utility paralleling limits.
- Operational Control: The Master Control (MC) unit automatically arbitrates engine start/stop sequences, oversees utility mains paralleling, manages base-loading or peak-shaving routines, and coordinates token-passing for safe dead-bus closing across the network.
⚡ Startup and Shutdown Sequence
- Startup Sequence:
- Verify all terminal wiring, including discrete I/O, communication lines, potential transformers (PTs), and current transformers (CTs).
- Energize the 18 to 32 VDC control power supply and verify that the dual-line vacuum fluorescent or LCD screens initialize without fault flags.
- Establish network communication across the connected EGCP-3 generator controllers to verify system handshaking and master arbitration status.
- Enable automated system control to permit coordinated generator sequencing and utility synchronizing as demand dictates.
- Shutdown Sequence:
- Ramp down active system power using automated base-load shedding or manual control commands through the master interface.
- Open utility and generator circuit breakers to isolate the busbars completely from active power sources.
- Shut down individual prime movers according to standard facility safety and operational procedures.
- De-energize the 24 VDC control power supply once the entire multi-generator plant is safely offline.
