The newly purchased electric gourd is found to be unavailable after the installation is completed. What is going on? Mainly because the electric gourd did not connect the rated work voltage, and it was unable to work. There are generally three cases:

1.Different power: Whether the power supply system is delivered to the electric gourd power supply. Generally, the test pencil is tested.

2. Defect: The electrical appliances of the gourd main control circuit are damaged, the circuit is disconnected or the contact is poor, which will also make the gourd motor lack of phase and cannot work properly. This is the case. The power supply given to the three -phase motor to burn the motor, or the gourd motor suddenly runs the electric operation to cause harm. Be sure to disconnect the gourd motor from the power line, only send the electricity to the main and control the circuit, and then move the start to start. And stop the switch, check the work of controlling electrical appliances and lines, and repair or replace the electrical or lines of problems. When confirming that the master and control circuit are not faulty, you can re -test.

3. The voltage is too low: the voltage of the gourd motor end is more than 10%lower than the rated voltage, and the motor starts torque is too small, so that the gourd can not hang the goods, but it cannot work. Essence.
