Let me explain the faults of automatic door manufacturers to everyone.

　　Let me explain the faults of automatic door manufacturers.

　　An automatic door is a control unit that recognizes the action of a person approaching the door (or some form of entry permission) as an opening signal, driving the system to open the door, and automatically closing it after the person leaves, controlling the opening and closing process.

　　Types of Automatic Doors

　　Automatic doors are classified into revolving doors, sliding doors, balance doors, speed gates, arc doors, air-tight doors, industrial doors, etc. based on their Applications.

　　Automatic doors are commonly used in facilities such as shopping malls, hotels, hospitals, stations, office buildings, and shopping centers, where there is a large flow of people and frequent operation of automatic doors. According to statistics, a normally operating automatic door runs about 876,000 cycles per year, which puts a heavy load on it, making it prone to various faults that can affect customer experience, damage company image, and even pose certain hazards to customers, such as incidents involving automatic door injuries.

　　Common Faults of Automatic Doors:

　　1. Not moving

　　1. First, check if there is power supply; if not, reconnect the power after cutting it off.

　　2. When the door is moving, is it dragging on the ground? If this phenomenon occurs, it will be troublesome when the door starts, as the main controller will judge it as a fault, engage self-lock protection, and stop the door's movement.

　　3. Check if the wheels of the door's hanging device have come off the track; if this happens, the door cannot move.

　　4. Check if the automatic door has installed a "safety light beam"; if there is dust on the receiver of the safety light beam, it may cause a malfunction, and the main control of the automatic door may mistakenly think that an object is in the middle of the door, causing it to not close.

　　2. Slow response of the automatic door

　　1. The detection range of the probe may be too small.

　　2. There may be dust accumulation inside the probe.

　　3. The object may be too heavy, exceeding the motor's pulling force.

　　3. The opening and closing sound of the automatic door is very loud

　　1. The wheels of the hanging device may have some wear due to long-term operation. When there is slight wear, the track and wheels can be cleaned, and a little lubricant can be added to the wheels' bearings, but do not oil the track and plastic wheels, as oil can easily attract dust, causing the wheels to wear out faster.

　　2. Some metal connectors may be loose; just tighten them.

　　3. Damage to the guide rail system can also cause the sound to become louder.

　　4. Friction may occur between the movable door and the fixed door, resulting in noise.

　　5. The beam may not have been installed smoothly during initial construction, or it may resonate with the overhead suspended ceiling.

　　5. The automatic door continues to open and close by itself

　　1. There may be objects such as pedestrians, vehicles, flags, or shadows of trees within the detection range of the sensor.

　　2. The detection range of the sensor may be too low; before the door closes, the sensor detects the movable door again, which may mistakenly think that the sensor is detecting a person moving, thus reopening the door.

　　3. The upper beam plate that fixes the sensing probe may be shaking, causing the probe to shake, preventing the door from opening and closing.

　　4. Carefully check if there are objects nearby the automatic door that emit strong electromagnetic waves; interference from strong electromagnetic waves can also cause malfunctions.
