⚙️ Operation Specifications and Usage Methods

• Installation Preparation: Mount the metal chassis securely inside an industrial control cabinet, ensuring adequate clearance space for proper ventilation and servicing. Verify that all external wiring utilizes twisted-pair shielded cables with foil or braided shielding to prevent electromagnetic interference.
• Parameter Configuration: Connect the unit alongside compatible load sharing and speed control modules. Configure internal base-loading settings to manage between 1 and 15 generator sets operating in a utility network.
• Operational Control: Use the auxiliary circuit breaker status to initiate soft loading, and configure the unload contact to handle controlled power shedding and bumpless transfers when paralleling engine-generator sets.

⚡ Startup and Shutdown Sequence

• Startup Sequence:
  1. Inspect all terminal wiring and ensure the continuous, uninterrupted AC power supply lines are securely connected.
  2. Energize the 115 VAC or 230 VAC input power source to activate the control circuitry.
  3. Start the prime mover and bring the oncoming generator up to operating speed and voltage.
  4. Engage the auxiliary circuit breaker to trigger the automatic soft load-in sequence, ramping the generator smoothly to its preset baseload level.
• Shutdown Sequence:
  1. Open the designated unload contact to trigger the automatic soft load-out process.
  2. Allow the internal controller circuitry to smoothly ramp down active generator power output to near zero.
  3. Open the main generator circuit breaker to completely isolate the unit from the shared electrical bus.
  4. Shut down the prime mover engine or turbine according to standard mechanical safety protocols, then cut off power to the control module once the system is fully offline.
