Operation Procedure Instruction Manual for Generator Sets

Generator sets serve as crucial equipment for emergency or temporary power supply. The standardization and safety of their operation procedures directly relate to the stable operation of the equipment and the safety of operators. To ensure the correct and safe use of generator sets, this operation procedure instruction manual is formulated to guide operators in performing standardized operations.

I. Pre-startup Inspection

Before starting a generator set, a comprehensive inspection must be carried out to ensure the equipment is in good working condition.

1. Oil Level Check: Oil is essential for the normal operation of the engine. The oil level should be between the upper limit (H) and the lower limit (L). Too much or too little oil can affect engine performance and even cause damage. Therefore, operators should carefully check the oil level to ensure it is within the normal range.

2. Coolant Check: The coolant keeps the engine running at an appropriate temperature. When checking the coolant, ensure it is at a level where it can be touched by a finger at the filling port to guarantee effective cooling. If the coolant level is insufficient, add it promptly to prevent engine overheating.

3. Battery Switch Check: The battery provides the power for starting the generator set. Check that both battery switches are in the "NO" position and rotate them clockwise to close them to the "NO" position to ensure the battery can supply power normally.

4. Fuel Level Check: Fuel is the energy source for the generator set's operation. When checking the fuel level, ensure it meets the fuel requirements for the working period, and the fuel port valve should be fully open to ensure a smooth fuel supply.

5. Appearance Inspection: Check the generator set for any damage or deformation on its exterior. Ensure all components are firmly connected and that there are no loose screws. Also, check that the equipment surface is clean and free of oil stains and debris accumulation, which could affect the normal operation of the equipment.

II. Startup and Operation Procedures

After completing the pre-startup inspection, you can proceed with the startup and operation procedures.

1. Manual Startup: Press the controller to the manual button position and then press the startup button to start the generator set. After successful startup, observe whether all data, such as frequency, voltage, water temperature, and oil pressure, are normal. These data are important indicators reflecting the operating status of the generator set and must be closely monitored.

2. No-load Operation: After successful startup, let the generator set operate without load for 2 to 3 minutes to stabilize all data. Then, press the closing button to close the circuit and supply power with load.

3. On-load Operation Inspection: During on-load operation, conduct inspections every 15 to 30 minutes. Observe for any oil or water leaks, abnormal sounds, and abnormal data displays, and record all displayed data. Meanwhile, the on-load power should be controlled below 80% of the rated power for long-term operation to avoid overloading and damaging the equipment.

4. Automatic Mode Startup: To start the generator set in automatic mode, simply press the automatic button to the automatic state. When the mains power fails, upon receiving the self-startup signal, the control system will automatically start the generator set and automatically close the circuit to supply power with load, achieving unattended automated operation.

III. Shutdown Procedures

Shutdown procedures are equally important and must be carried out in accordance with standardized processes.

1. Unloading Operation: Gradually reduce the load until the generator set operates without load. Turn off all electrical equipment and press the opening button to open the circuit and disconnect the load switch to prepare for shutdown.

2. No-load Operation for Cooling: Operate the generator set without load for 3 to 5 minutes to allow all engine components to cool evenly and prevent local overheating caused by sudden shutdown, thereby extending the equipment's service life.

3. Shutdown Button Operation: Press the red shutdown button to stop the engine operation. After shutdown, place the control switch on the control panel in the "stop" position (if the automatic function is not required) to ensure the equipment is in a safe state.

4. Automatic Mode Shutdown: In automatic mode, when the mains power is restored, upon receiving the shutdown signal, the control system will automatically open the circuit, enter the automatic delay cooling state during shutdown, stop operation after a 130-second delay, and enter the automatic standby state, waiting for the next startup.

In conclusion, the operation procedures of generator sets must strictly adhere to standards to ensure that operators use the equipment correctly and safely, guarantee the stable operation of the equipment, and prevent safety accidents and equipment damage caused by improper operation.
