1) Confirm the power generation mode, whether it is generator power generation or directly connected to 380V large power. First, ensure that the power generation is normal, and observe whether the voltage and current values during operation are within a reasonable range (350V-420V);
2) If the fan is turned on and stopped, check the display of the integrated protector. If only the overload light is on, check the current value at the time of shutdown and adjust it to a suitable value. If the lack of phase light is on, check whether there is any looseness in the wiring of the fan.
3) If the water pump is turned on and stopped, first check whether the water pump is blocked or stuck, and then check the display of the integrated protector. If only the overload light is on, check the current value at the time of shutdown and adjust to a suitable value. If the lack of phase light is on, check the pump motor all the way If there is any looseness in the wiring, if the phase is still displayed after tightening, contact the after-sales service to dismantle and inspect the motor (to distinguish between the plunger pump and the vertical pump), and also confirm the customer’s water supply method to see if the water supply equipment has high pressure (high pressure) The water supply tank can also cause overcurrent);
4) For generators generating equipment, if the current value is set reasonably but still cannot work continuously, consider whether the generator has insufficient power and cannot drive the load. Customer can directly connect to the large power test machine. If it does not stop the machine, contact the generator The generator manufacturer repairs the generator;
5) If it is an old PLC, it stops when the fan, pump, left and right are working at the same time, consider whether it is caused by signal interference. This kind of shutdown will automatically recover after a period of time after the action stops, and a filter can be installed to solve it. ；
6) Check the limit switch (normally the middle limit is normally closed, if the line is wrongly connected as normally open, there will be no action on the left and right);
7) If a soft starter cabinet or inverter is installed, first look at the screen prompts and judge according to the error code.
