How to safely turn off the generator when the power comes back on?

To safely turn off a diesel engine generator when the power comes back on, follow these steps:

1. First, ensure that the generator is no longer needed and is safe to shut down. 

2. Turn off all the appliances and equipment and power the generator. When you turn off the generator, it prevents potential damage or surges.

3. For the manual transfer switch(Changeover switch), go to it and move the liver from the designated ON position, usually marked "GENERATOR," to the established public power supply marked(Name of the company that supplies the electricity) all the way passing through the ''OFF'' position to engage it firmly (to avoid partial contact) at the designated "ON."

4. Permit the generator to cool. It is crucial to let the generator cool down before attempting to turn it off because diesel engines produce a lot of heat. Depending on how big the generator is and how hot the environment is, it can take a short or longer.

• Wait for 1 to 2 minutes before putting the generator off. Reason: You must enable coolant and lubricant to disperse the heat produced by the bearing, shafts, and combustion chamber. The cooling-off period is at this time.

• This practice is perfect for turbocharged engines. The high temperature of the exhaust is a threat to the bearings and oil seals of the turbocharger. When the engine is running, the circulating oil dissipates this heat. Still, if the engine stops abruptly, the turbocharge temperature might be increased, and overheating will result in a jammed bearing or failed oil seal.

5. Turn off the generator; By flipping the switch or key or pressing the "off" button on the generator's control panel.

6. Secure the generator. It may involve covering the generator with a protective cover, locking it securely, or taking other measures to prevent unauthorized access or tampering.

It is essential to follow these steps carefully to ensure the safe and proper shutdown of the generator. If you are unsure how to turn off the generator or have any concerns about its operation, consult the manufacturer's instructions or seek the assistance of a qualified technician.

It is essential to turn off a generator when the power comes back for several reasons:

Safety: Generators can produce dangerous levels of carbon monoxide gas, which can accumulate in poorly ventilated areas and be deadly. When the power comes back, it is essential to turn off the generator and open windows to allow the gas to dissipate.

Protection of the generator: When the power comes back, the generator will no longer be; needed and can be; turned off to preserve its fuel and prevent unnecessary wear and tear.

Protection of the electrical grid: When the power comes back, the generator is no longer needed to provide power to your home. If the generator is left running, it could potentially feed energy back into the electrical grid, which can be dangerous for utility workers and can damage the grid.

Saving money: If you have to keep the generator running when the power is back, it is a waste of fuel and can be costly. It is more economical to turn off the generator and use the leverage from the grid.

In summary, turning off the generator when the power comes back on is essential for safety, the protection of the generator and electrical grid, and cost savings.

When the power comes back, there are numerous ways to turn off a diesel engine generator:

1. A generator and the main power supply can be switched automatically by an automated transfer switch (ATS). The ATS will recognize central control when the power is; restored and turn the generator off automatically.

2. An MTS, or manual transfer switch, is a switch that enables the user to switch between the generator and the primary power source manually. The operator can manually switch the MTS to the primary power source when the electricity returns, which will turn off the generator.

3. Emergency Power Off (EPO) Button: Many generators have an emergency power off button that you can use to shut down the generator in an emergency quickly. When the power comes back on, the operator can use the EPO button to shut off the generator.

4. Shutting off the Battery Charging Circuit: Some generators have a battery charging circuit that you can use to shut down the generator.

It is essential to follow the manufacturer's instructions for shutting off the generator to ensure it is safe and correct.

Turning off a diesel engine generator when the power comes back on can be hazardous for several reasons. 

• One of the main hazards is that the generator may not have time to cool down properly before you turn it off. It can lead to overheating and potentially cause damage to the engine.

• Another hazard is that the generator may not have time to stabilize before the power turns on properly. It can cause voltage fluctuations that damage electrical equipment and appliances connected to the generator.

• Additionally, turning off a generator when the power comes back on can cause a sudden change in the load on the generator, which can also cause voltage fluctuations and potentially damage the generator or connected equipment.

Please allow the diesel generator to run for a few minutes after the power comes back to cool down and stabilize before turning it off. It can help to reduce the risk of damage to the generator and any connected equipment.

 

When to use the emergency stop button? 

The emergency stop button on a diesel engine generator is engaged when you need the generator to be off immediately. It could include conditions where the generator is experiencing a malfunction or where there is a risk of injury or damage to personnel or equipment.

It is essential to use the emergency stop button only when necessary, as shutting down the generator in this way can cause damage to the engine or other components. It is also essential to follow any specific guidelines or procedures the manufacturer provides for shutting down the generator in an emergency.

Examples of situations where it may be necessary to use the emergency stop button on a diesel engine generator include:

• If you observed a mechanical issue with the generator that is causing it to operate improperly or pose a risk to people or property; 

• If there is a fire or other hazardous situation involving the generator; 

• If someone is injured or trapped near the generator, it must be off to ensure their safety.

• If the generator produces hazardous levels of exhaust fumes or other dangerous emissions; 

• If the generator produces excessive vibration or noise, causing damage or posing a safety hazard.

It is essential to follow any specific guidelines provided by the manufacturer for using the emergency stop button and to only use it in emergencies with a risk of injury or damage.

Generator shutdown guide 

1. In the case of power restoration, it is essential to know how to turn off the generator.

2. There are a few different ways to turn off the generator.

3. Make sure you know the location of the emergency shutoff switch.

4. Follow the steps to turn off the generator.

5. If you use a portable generator, always keep the key in the ignition and the generator off until you are ready to use it.

6. If you use an electrician’s or contractor’s generator, ensure it is labeled “off” when not using it.

7. If you use a standby generator, ensure the fuel is stored correctly and the generator is safe.

8. Ensure that the fuel is drained adequately of sediments and that the generator is safe.

9. If the public power is off, turn on the generator only if you are sure you need it.
