1 Leaf Door fixed
(1) Door leaves do not move, of course, first of all to check if there is a power supply to it, if it is due to the cause of electricity is connected to the source.
(2) Whether there is a drag-and-drop activity doors, if this phenomenon, the door will be very difficult to start, the main controller will be considered to have obstacles and self-locking protection, so that the doors stop movement;
(3) Check the door door hanging the wheel part is not falling off the track, if there is this phenomenon, the door will not move.
2 Automatic Door response delay
(1) The detection range of the sensor probe is too small.
