Four reasons why the lifting door cannot be opened normally

     1. The emergency stop switch is not turned out, and the emergency stop switch of the lifting door will not operate when it is pressed. It needs to be manually rotated out of the emergency stop switch in the direction of the knob to open normally.

     2. The power supply is in poor contact. It is necessary to check the wires of the lifting door control system to avoid failure to open and close due to poor contact.

     3. The power of the remote control is insufficient, just replace the battery.

     4. The remote control is not within the sensing range, the remote control sensing range of the lifting door is within 50m, if it exceeds the distance, it will not be sensed.

     The problems with the opening and closing of the lifting door are generally the above types. According to different usage conditions, there may be other problems. If you need consultation, you can call us.
