The circuit control system of the automatic retractable door mainly includes: operation key box, control board with CPU as the core, remote control, and detection and control circuit composed of some sensors. Because the structure of the automatic retractable door is much more complicated than the ordinary door structure, everyone should pay attention to the maintenance and repair methods in daily life. Today Xiao Bian came to share with you some automatic retractable door repair methods.
[automatic retractable door working principle]
The main structure and working principle of the automatic retractable door: The nuclear door is mainly composed of a door body, a driver, and a control system. The door body is made of high-quality aluminum alloy and common square pipe, and is hinged on the principle of parallelogram. It has a flexible and flexible stroke. The driver is driven by a special motor, the worm gear is decelerated, and there is no manual clutch. When the power is turned off, it can be manually opened and closed. The control system has a control board, a button switch and a user remote control device.

First, why the automatic rewind phenomenon often occurs when the door is open The automatic rewinding of the door is a malfunction of the infrared anti-jamming ability or the radiation sensor. Generally take the code or replace the PCB board to solve, you can also push the transistor of the infrared output relay in the electrode of a 47uf electrolytic capacitor to filter external interference. The general-purpose circuit now used is divided into A and B versions. The signal channel processing in the circuit does not need to be coded again, but it is necessary to use the A and B versions for opening the door.
2. What is the problem of trembling during the operation of barriers? The occurrence of trembling during operation is mainly due to the fact that the length (weight) of the rod is not proportional to the spring tension. If it is the next rod will not tremble, the rising rod will tremble, indicating that the tensile spring tension is too strong, can loosen the spring tension; the upper rod will not be the next rod trembling, is the spring tension is insufficient, to adjust the tension spring or replace the pull Spring to deal with.
Third, can switch but can not stop
The switch can indicate that there is no problem with the red, white and yellow lines of the motor line, and the signal line is not short-circuited. The main reason is that the limit signal is not sent to the controller or the controller limit function is bad. Can not automatically stop: a. Limit sensor K1, K2 at the same time open (limit sensor is a magnetic field is closed, no magnetic field is disconnected); b. public line blue circuit breaker. c. controller is bad; the same method of inspection using the above inspection method .
Fourth, can be closed (open) can not be opened (off)
Can be switched off (on) not on (off). Description The motor white common line is good. It can be measured whether the motor red (yellow) color and white line are connected, and then the blue and gray (green) color signal lines and K2 (K1) are measured. The sensor switch is short-circuited. The inspection method can refer to "can not switch."
Fifth, the automatic retractable door can not be switched first check whether there is electricity, insurance tube burned, if the fuse is broken, you must do a full inspection.
Unplug the underground cable plug in the communication room and use the multimeter Rx1 to measure whether the red, white and yellow wires of the motor are connected. (yellow (red) and white, the resistance should be about 15 ohms, yellow and red should be about 30 ohms) Then, use R×10K to measure whether or not there is a certain resistance with other lines (mainly to check if there is an indirect short circuit between the line and the line). The red, white, and yellow three motor wires are disconnected (infinite resistance), and then the red, white, and yellow in the terminal junction box are detected. If they are the same, the red, white, and yellow wires in the underground cable are disconnected; In the hood, measure the three lines at the plug connected to the head of the door. If they are the same, it means that the line from the end of the line to the communicator is broken (including the poor contact of the plug); if it still does not work, measure the motor directly Stator coil is open circuit.
Xiao Bian concludes: The above is Xiao Bian about the automatic retractable door repair method to everyone's introduction, I believe that the friends who read the automatic retractable door can have more understanding, but also hope to give maintenance and repair of automatic retractable door friend They help. For more relevant knowledge, please continue to pay attention to this website information platform.
