(Summary description)1. Common phenomenon: the control box indicator does not light up, the display screen and the warning light do not light up, open, close, stop, and do not work. If the power supply is poorly connected and the voltage is too low, the operation of the retractable gate will be unstable and the control will fail. Automatic stop in the middle, the robot is easy to go wrong, or while the motor rotates, while not rotating, etc.

Information

1. Common phenomenon: the control box indicator does not light up, the display screen and the warning light do not light up, open, close, stop, and do not work. If the power supply is poorly connected and the voltage is too low, the operation of the retractable gate will be unstable and the control will fail. Automatic stop in the middle, the robot is easy to go wrong, or while the motor rotates, while not rotating, etc.

2, power failure

A. The display screen is off, and the indicator light of the control box is off.

B. The display is on, and the control box indicator is on.

Judgmen

C. Circuit problems, check and repair the circuit.

D, all transformers are burned out. Note that if you press the wrong 380V or the zero line contact reef is badly connected to the live line to form 380V, it will cause high voltage and burn out the components.

E. Measure whether the control box and the input voltage are under 200V when the motor is running. If it is lower than 200V, it may be caused by too small or too long wire diameter, so increase the wire diameter.

F. Measure the voltage through the 220V wire in the gate row junction box and the guard room to determine the fault location.

G. Measure whether the voltage is higher than 220V, check the neutral line for bad contact, and replace the burned-out component after the power supply is normal.

H, 220V voltage is sufficient, it may be due to poor contact somewhere in the line. Check the line. If you can’t find it, you can pull a 220V power supply from another place to verify the solution.
