Diesel generator power distribution control section Troubleshooting

First, when the key to "START", the Diesel Generator Set does not start 
1, check the key switch operation is good 
2, check whether the fault indication, the repair and reset 
3, check the battery voltage of Generator Set, such as the voltage is too low, you need to recharge the battery to full, such as the voltage is normal, you need to step through the correct voltage signal was sent to all the control aspects, such as the throttle valve and start the motor, etc. 
4, check whether the emergency stop button of Generator Set is relax 
Second, when the "START" signal is entered correctly, but the manual / automatic will not turn on 
1, check whether the emergency stop button of Generator Set is relax 
2, check whether the control key "STOP" position 
3, check for fault indication, the repair and reset 
4, check the battery voltage of Generator Set, such as the voltage is too low, you need to recharge the battery to full, such as the voltage is normal, you need to check the signal was correctly sent to all control areas, such as the throttle valve and start the motor and so on. 
5, if all external electronic control part of the Generator Set no problem, you should replace the corresponding part of the electronic control 
Third, start the motor running, but the unit vain car 
1, check the fuel level, and to ensure that tubing is properly connected 
2, the mechanical speed control system unit of Generator Set, check the throttle valve is correct pull 
3, the electronic speed control system unit, check whether the correct access and EPG power voltage is normal 
4, the electronic speed control system unit, start the motor running, Measure the MPU have the correct AC voltage signal 
5, check whether the machine speed of Generator Set has reached or exceeded the normal speed setting of the start 
6, check the fuel delivery system is blocked 
7, check the air filter of Generator Set is clogged 
8, cold regions of the unit, before the start, make sure the unit warm-up 
Fourth, the high-temperature fault alarm / shutdown 
1, check whether the unit overload 
2, check the radiator of Generator Set is blocked 
3, check the fan belt tightness 
4, standby group completely cooled, check the adequacy of the cooling water level 
5, check the water temperature sensor of Generator Set is damaged Wei 
6, check whether the right to open the thermostat valve 
7, check the gap between the pump and the tank is correct 
8, confirm the room temperature of Generator Set is not higher than 40 °C 
Fifth, low oil pressure fault alarm / shutdown 
1, check the oil level of Generator Set
2, check the oil quality and viscosity 
3, check the oil temperature 
4, check the oil pressure sensor of Generator Set is damaged 
5, check whether the oil filter and oil quilt block 
Six speed downtime 
1, check whether the abnormal speed meter indication 
2, the mechanical speed control system of Generator Set, check the throttle lever is flexible, and ensure the correct adjustment 
3, the electronic speed control system of Generator Set, check the throttle lever is flexible, check whether the enforcement agencies the right action, and ensure the correct adjustment EPG 
4, re-calibration and adjust speed limits to protect 
5, troubleshooting, control panel will reset the alarm signal 
Seven, high voltage alarm 
1, measuring the actual value of the output voltage unit of Generator Set
2, and confirm that there is no deviation meter 
3, such as high voltage actual value, according to the steps detailed examination and re-adjust the AVR 
4, confirm the very nature of the load, power factor does not advance 
5, confirm the unit speed / frequency normal of Generator Set
6, such as the actual value of the normal voltage, check voltage display part of the circuit is correct 
Eight, low voltage alarm 
1, measuring the actual value of the output voltage unit of Generator Set
2, and confirm that there is no deviation meter 
3, such as the actual value of the voltage is low, according to the steps detailed examination and re-adjust the AVR 
4, confirm the unit speed / frequency normal of Generator Set
5, such as the actual value of the normal voltage, check voltage display part of the circuit is correct 
6, confirm that no major bias voltage three-phase 
7, confirmed that no phase phenomenon of Generator Set
8, confirm that when an alarm occurs, the load changed slightly 
9, confirm the operation unit is not overloaded of Generator Set
10, check the voltage high and low alarm settings are correct and reasonable limits
