What if the electric rolling gate of the garage can't stop rising or falling?

Generally, it is caused by the short circuit of the remote controller, but this situation only sends instructions to the signal receiver of the shutter door, and the signal receiver of the shutter door drives the motor to work continuously after receiving the instructions;

However, due to the limiter, the motor will enter the non-electric sleep state every time it is started. Over and over again, those who are slow to respond to the limiter can see that the shutter door has been shaking at the end of opening or closing.

The limiter is sensitive, the motor jitter can hardly be seen, the shutter door does not move, but the signal receiver has been working. If there is no limiter, the power supply must be cut off immediately, otherwise the motor or shutter door will be damaged.

Maintenance knowledge of electric shutter doors;

1. When using the electric shutter door, try to keep the controller and voltage stable, and don't install it in a very humid environment. In addition, don't turn on the remote control at will. If wires are found on the door body, they should be handled in time. Pay attention to whether the passage is blocked to prevent the door from falling down. If there is any abnormal reaction, stop the motor immediately.

2. Regularly check the switch of the up-and-down stroke of the electric shutter door and add lubricating oil to the stroke controller to maintain normal and good operation. In addition, the operator manually controls the shutter door, checks the operation of the detector, and proofreads the position of the up-and-down travel switch.

3. The operator had better check the manual switch and manual lifting decoration of the electric shutter door regularly to prevent the electric shutter door from failing in an emergency or causing unnecessary safety accidents.
