Common faults

The main factors contributing to the fault of remote operation of electric roll-up doors are as follows:

1. Transmitting Power: A higher transmitting power allows for a longer distance, but it consumes more power and is more likely to cause interference.

2. Receiving sensitivity: The increase in the receiving sensitivity of the receiver extends the remote control distance, but it is easy to be interfered, causing misoperations or uncontrolled operations.

3. Antenna: The antenna is of the straight line type and is parallel to each other, with a long range for remote control but occupying a large amount of space. By stretching and straightening the antenna during use, the remote control distance can be increased.

4. Height: The higher the antenna, the farther the remote control distance, but it is limited by objective conditions;

5. Blockage: The wireless remote currently in use operates on the national standard UHF frequency band, which has similar propagation characteristics to light. It propagates in a straight line and has less scattering. If there is a wall between the transmitter and receiver, the remote control distance will be greatly reduced. If the wall is made of reinforced concrete, due to the conductor's absorption of electromagnetic waves, the impact will be even greater. Since there are many different systems to maintain when repairing electric roll-up doors, there will be many problems encountered during operation. Of course, attention is also needed during maintenance.
The following are the precautions:
(1) Due to the shared ground wire for maintenance of the electric roll-up door, the central door lock, and the electric antenna, a typical fault occurs: the central door lock becomes inoperable. When maintaining the roll-up door, small power appliances such as the radio and the lift indicator light operate, and the result is due to the ground point being grounded incorrectly, leading to mutual electrical connection.
(2) The sealing and dustproof of electric roll-up doors are particularly important: There is a layer of plastic protection on the inner panel of the electric roll-up door, and its damage will lead to the entry of dust into the electric roll-up door, which may interfere with the maintenance movement of the electric roll-up door.
(3) When disassembling and assembling the electric roll-up door for maintenance, it is very important to pay attention to the correct installation position. All the bolt connection holes are elliptical holes. Before maintenance, it is absolutely necessary to ensure that the roll-up door does not interfere with the lifting and lowering.
(4) The size accuracy of the electric roll-up door will have a significant impact on the life of the elevator motor for the maintenance of the roll-up door. This is because the guide groove is installed on the electric roll-up door, and the elevator moves within the guide groove.
Electric roll-up doors are composed of multiple jointed door panels that are connected in series. They are driven by an electric motor unit, and the roll-up doors rotate up and down within a fixed track centered on the top roll shaft. These doors are suitable for public places such as commercial doors, garages, shopping malls, hospitals, and industrial and mining enterprises, or residential use. They are especially convenient and quick to open in places where the door opening is large and it is inconvenient to install a ground-level door body. Examples include garage doors, fire-resistant roll-up doors in shopping malls, and hangar doors. Electric roll-up doors, crystal roll-up doors, and stainless steel perforated roll-up doors are all available at QiChuang Door Industry.
