wait until the engine temperature rises to normal before loading |
| crankcase pressure too high |
engine breather net blocked, clear it |
| load overload |
reduce load current |
| diesel fuel is of poor quality or contains moisture |
check and replace |
| injector failure or carbon deposition |
injector calibration |
| 5. Abnormal Engine Sound |
injector clogged |
injector calibration |
| incorrect valve clearance |
adjust valve clearance |
| inlet and exhaust steam leakage |
after inspection, lock the pipeline |
| engine operating temperature is abnormal |
check ambient ambient temperature and engine temperature |
| 6. Engine Water Temperature Is Too High |
insufficient cooling water |
check the cooling water in the water tank |
| there is air in the cooling water pipe |
air in the discharge line |
| blocked radiator fins |
remove debris and wash |
| fan belt is broken or not tight enough |
replace or adjust |
| blocked or twisted cooling water lines |
update after checking or contact the original factory |
| cooling water thermometer malfunction |
replace |
| broken fan |
replace |
| 7. Engine Oil Pressure Is Too Low |
insufficient oil, not up to standard |
add oil |
| oil filter clogged |
replace |
| engine temperature is too high |
refer to failure scenario 6 |
| oil pump failure |
contact the original factory |

replace |
| 8. After The Generator Set Is Started, There Is No AC Output |
power circuit breaker not turned on |
open |
| AVR failure |
contact the original factory |
| diode fault in generator head |
replace |
| instrument failure |
replace |
| 9. The Generator Set Cannot Be Started After A Power Failure |
engine won't start |
refer to failure case 1 |
| the power outage time is too short (fake power outage) |
the power failure time is too short, and the generator does not start when the engine delay start time is not reached |
| ATS does not send a signal to start the generator |
ATS failure, repair |
| the remote control circuit between ATS and generator set is loose or disconnected |
check wiring |
| 10. The Alternator Is Abnormal |
voltage is too high |
adjust the voltage adjustment knob |
| voltage is too low |
adjust the voltage adjustment knob |
| voltage swing is unstable |
adjust the "Stable Adjustment" of AVR |
| load current is too high |
reduce load current |
| capacitors on the load side |
turn off the capacitor |
| 11. Abnormal Shutdown of The Generator Set |
low oil pressure shutdown |
- check the oil dipstick for sufficient oil
- whether there is oil leakage or damage on the cylinder wall
- check whether the oil pressure switch operates normally
|
| high water temperature shutdown |
- check the cooling water tank and cooling water pipeline for leaks.
- check that the water level is sufficient.
- check whether the water temperature switch function works normally.
|
| High (low) speed shutdown |
- Check whether the frequency and RPM readings are too high or too low after the engine is started.
|
| overload shutdown |
- test with less equipment used.
- avoid multiple devices starting at the same time.
|
| overcurrent shutdown |
- check whether there is any abnormality at the equipment side (motor).
- test with less equipment used.
- avoid multiple devices starting at the same time.
|
| high (low) voltage shutdown |
