The unit cannot be shut down. It may be due to mechanical factors or human factors. Due to the difference in the design, type and control system of the unit, you need to know what is the cause. You can contact us directly, and our company will have professional personnel to provide you solve the problem.
The following table shows the simple troubleshooting methods for general unit failures:
failure situation possible reason Solution 1. The engine cannot be started or is difficult to start Insufficient battery voltage Check whether the battery fluid is sufficient and whether the automatic charger works Daily fuel tank switch not turned on Turn on the switch and drain the air in the oil line There is air in the diesel line Air in the discharge line Diesel filter clogged change filter Loose control wiring or open circuit Check wiring Autostart plate failure replacement or repair Start subsidy relay failure replace Starter motor failure Remove for testing or repair Internal damage to the engine Please check with the original technician governor failure Please check with the original technician 2. The engine cannot be stopped after starting Autostart plate failure replacement or repair Loose control wiring or open circuit Check wiring Engine governor failure Please check with the original technician Engine stop solenoid switch failure replacement or repair 3. Insufficient engine horsepower Diesel system has air Check the diesel pipeline for leaks and tighten the screws Diesel filter clogged change filter Air filter clogged change filter Diesel fuel is of poor quality or contains moisture replace Insufficient rated speed (insufficient frequency) Corrected frequency value Too much engine oil Check the oil and correct it if too much Load has exceeded engine horsepower reduce load current Fourth, the engine smoke is not normal Too much engine oil Check the oil and correct it if too much Engine temperature is too low 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</p Add oil Oil filter clogged replace Engine temperature is too high Refer to Failure Scenario 6 Oil pump failure Contact the original factory Oil pressure gauge failure 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 Refer to failure case 5 High water temperature shutdown Refer to Failure Scenario 6 High (low) speed shutdown Check the engine frequency value and correct it Overload shutdown reduce load current Overcurrent shutdown reduce load current High (low) voltage shutdown Refer to Failure Scenario 10 Battery high (low) voltage warning Check the charger and battery WARNING: Start the machine only when it is safe to do so; do not attempt to start the machine when you know it is unsafe.
