How to run a quick diagnosis of your diesel generator?

Your generator is your most reliable partner in business, it powers your operations for maximum uptime and ensure that you’re able to meet the demands of your customers. However in that rare occasion, your engine may have stopped running and you need a quick diagnosis to identify the problem. Below is a checklist to help get you going.

Things to check for in a diesel generator

• Check that the opening of the fuel supply valve and cooling water stop valve are unobstructed;
• Check if the alarm indicator of the test button on the distribution screen is on;
• Check the meters are at zero and the switches on the distribution screen are on;
• Start air inlet and exhaust;
• Press the start button on the distribution screen to start the generator. If the first start fails, press the reset button on the distribution screen, wait for the alarm to be eliminated, the unit will return to normal state ready for the second start. After the generator is started, check that the sound of the machine running is normal, the cooling pump running indicator light and the road meter indication are normal, start successfully.
• Check that the oil temperature, water temperature and oil pressure of the generator are within normal range.
• Check that the output voltage and frequency of the equal-parallel generator are consistent with those on the bus row.
• After the manual parallel operation is successful, contact the low voltage power distribution room immediately to make sure whether the general distribution panel feedout switch can be closed for power transmission.

Operational management

• Check each indicator instrument according to the specified time, pay attention to the pressure of lubricating oil and whether the water temperature has changed. The pressure of lubricating oil shall not be lower than 150 KPA, and the temperature of cooling water shall not be higher than 95.
• Check crankcase oil level, fuel tank oil level, radiator water level, below normal position should be replenished.
• Observe every instrument and alarm indicator lamp of power distribution screen whether it is normal or not. Where a red light indicates a failure, the green light is a normal operating indicator.

How to stop a Generator Set
