The main board of retractable door circuit has four buttons, namely, open door, close door, stop and function. I just want to know the function keys.

1. The telescopic door remote controller is a remote control device that uses radio signals to control various mechanisms in the distance. After these signals are received by the remote receiving equipment, they can instruct or drive other corresponding mechanical or electronic equipment to complete various operations, such as closing the circuit, moving the handle, starting the motor, etc., and then these machines will carry out the required operations. As a complementary remote controller with infrared remote controller, it has been widely used in garage doors, electric doors, road brake remote control, burglar alarm, industrial control, wireless smart home and other fields.

Second,? The electric control system of the electric telescopic door, that is, the traction control part of the door body, consists of the following parts: 1, the chassis (usually die-casting cast iron process or thick steel plate forging) as the base of the driving motor, which fixes the motor and increases the traction; 2. The motor (door opener) adopts the worm-wheel motor chain or gear transmission mode, and the chain transmission is a scientific and conventional design structure. The electric telescopic door has the advantages of stable operation, long service life, convenient maintenance and low failure rate. Gear transmission needs to be able to play a role in the oil-immersed closed state, otherwise the maintenance cost will be higher in the future. 3. Magnetic control switch (electric telescopic door limit device). 4. Detector (device for detecting the front and rear magnetic signals of the trackless door chassis). 5. The main control board is the core component used to control the opening and closing of the electric telescopic door. 6. Control the receiving equipment (control box, remote controller). 7, infrared anti-collision device (in the process of closing the electric telescopic door, if you meet a vehicle or a pedestrian, the electric telescopic door will immediately stop and run in the opposite direction to ensure the safety of pedestrians and vehicles). 8. Electronic display screen (divided into scrolling screen and fixed screen). 9. Infrared anti-climbing device. 10, main drive wheel.

3. The main functions of the function keys of the telescopic door remote controller are: 1, which can adjust the walking speed of the door. 2, switch time limit, that is, adjust the maximum stop position when the magnetic switch controls the door switch. 3. Adjust the infrared electronic anti-climbing and anti-collision device.
