Usage Method

1. Pre-Operation Inspection (Mandatory)

2. Start-Up Procedures

1. Mode Selection: Use the control system to choose either "Automatic" mode (triggered by timer or remote control) or "Manual" mode (activate by pressing the start button).

2. Start-Up Monitoring: Let the unit increase its rotational speed to 1500r/min, ensure the oil pressure is ≥0.3MPa, and the water temperature rises to 80℃ (this process usually takes 3 to 5 minutes).

3. Loading Process: Close the output switch → Keep the initial load at ≤50% during the first start-up (run for 30 minutes) → Gradually raise the load to full capacity.

3. Operation Monitoring

- Real-Time Parameter Check: Monitor key parameters continuously, ensuring voltage is within 380V±5%, frequency is 50Hz±0.5Hz, water temperature does not exceed 95℃, and oil pressure is ≥0.2MPa.

- Recording Requirement: Record all operating parameters once every hour. If any abnormality is found, unload the unit immediately and shut it down for inspection.

4. Shutdown Procedures

1. Unloading: Reduce the load to 0 → Disconnect the generator's output switch.

2. Cooling: Let the engine run at idle speed for 3 to 5 minutes (to prevent overheating of the internal combustion engine).

3. Shutdown: Press the "Stop" button → Close the natural gas valve → Cut off the control power supply (disconnect the battery wiring if the unit will be out of service for a long time).
