The opening and closing speed of rolling shutter door leaf is too slow
(1) The speed adjustment of the controller is too slow.
(2) Abnormal voltage.
(3) The belt may be too loose.
(4) The stop wheel rubs against the track.
(5) The movable door leaf may rub with the guide rail or with the fixed door leaf or with the floor.
When installing the rolling shutter door, many problems will be encountered during operation. Of course, attention should also be paid to during maintenance:
(1) As the electric rolling shutter door maintenance shares the grounding wire with the central door lock and electric antenna, a typical fault occurs: the central door lock is not easy to use. When opening and closing the rolling shutter door for maintenance, the radio, elevator indicator and other low-power appliances work. The result is that the grounding points are not grounded and connected with each other
(2) When disassembling and repairing the electric rolling shutter door, pay attention to the correct installation position. All bolt connection holes are oval holes. Do not interfere with the maintenance and lifting of the front rolling shutter door
(3) The dimensional accuracy of the electric rolling shutter door will seriously affect the service life of the elevator motor for the maintenance of the rolling shutter door. Because the guide groove is installed on the electric rolling shutter door, the elevator moves in the guide groove
(4) The sealing and dust prevention of the electric rolling shutter door is particularly important: the inner plate of the electric rolling shutter door has a layer of plastic protective layer, which will cause dust to enter the electric rolling shutter door after it is damaged, which will interfere with the maintenance movement of the electric rolling shutter door in serious cases
