⚙️ Operation Specifications and Usage Methods

• Installation Preparation: Ensure all power sources to the marine or industrial control panel are locked out and tagged out. Mount the module securely inside the designated enclosure, taking advantage of its Lloyd’s Register certification for marine-grade vibration and environmental resilience. Verify line voltage connections for the 115 or 230 VAC bus and generator inputs.
• Parameter Configuration: Adjust the phase angle settings, confirm the 1:1 voltage matching ratio, and configure the output jumper or terminal selection to match one of the three available impedance options: high impedance, low impedance, or EPG.
• Operational Control: Connect the synchronizer outputs to the corresponding governor speed control or actuator circuit to automate marine generator frequency matching, phase alignment, and breaker closure commands.

⚡ Startup and Shutdown Sequence

• Startup Sequence:
  1. Inspect all AC voltage and control wiring terminals to ensure correct phase rotation, marine-grade insulation, and secure physical connections.
  2. Energize the main AC bus and 115/230 VAC supply lines, verifying stable input frequency (50/60 Hz).
  3. Start the prime mover and bring the incoming generator up to rated speed and nominal voltage.
  4. Engage the SPM-A synchronizer to actively monitor phase angle and voltage differences, allowing it to automatically issue the breaker close command when synchronization parameters are met.
• Shutdown Sequence:
  1. Transfer active electrical load away from the synchronized generator using manual or automated base-load shedding.
  2. Open the generator output circuit breaker to decouple the unit from the shared electrical bus.
  3. Initiate the prime mover shutdown sequence and allow the engine or turbine to cool down completely.
  4. De-energize the AC input power supplies and control circuits once the system is fully offline.
