Summary of Common Maintenance Methods of Parking Lot Gate System - Tiger Wong Technology

Intelligent gate is the most common problem in parking lot system management. What do you know about the faults and troubleshooting methods of some gates? I. maintenance methods for parking lot gate that cannot take off and land: 1. First check whether there is electricity and whether the fuse is burned. If the fuse is broken, a comprehensive inspection must be carried out. 2. Unplug the underground cable plug in the reception room and measure whether the red, white and yellow leads of the motor are connected. If they are connected, it indicates that the red, white and yellow leads in the underground cable are open; Not connected: disassemble the hood and measure the three lines at the plug connecting the door row and the machine head. If they are connected, it indicates that the line from the end of the door row to the reception room is broken (including poor contact of each plug); If it still fails, directly measure whether the motor stator coil is open circuit. 3. The motor leads are only connected in red and yellow, but not in white.

Check whether the motor stator is hot. If it is hot, it means that the motor thermal protection shutdown cannot be switched on and off. If it is not hot, check whether the starting capacitor of 20uf is invalid. 4. If the motor is in good condition or cannot be switched on and off, measure whether the blue, green and gray limit signal lines are short circuited. 5. If the motor line and signal line are good or cannot be switched on and off, it indicates that the control box is faulty. II. Maintenance method for parking lot gate switch failure: first measure whether the red (yellow) and white lines of the motor are connected, and then measure whether the blue and gray (green) signal lines and K2 (K1) sensor switch are short circuited. III. The parking lot gate can be switched but not shut down.

Maintenance method: if it can be switched, it means that there is no problem with the red, white and yellow lines of the motor line, and there is no short circuit in the signal line. The main reason is that the limit signal is not sent to the controller or the limit function of the controller is bad. IV. the parking lot gate cannot be shut down automatically. Maintenance methods: 1. The limit sensors K1 and K2 are open at the same time. 2. Public line blue circuit breaker. 3. Check whether the controller is broken. V. maintenance method: check whether the length (weight) of the brake rod is directly proportional to the spring tension.

Vi. maintenance methods for the gate rod of the parking lot gate in place: 1. The thyristor in the control box is broken: as soon as the control box is plugged in, it runs automatically, indicating that the thyristor is penetrated. 2. The switch is in place without continuity: swing the brake rod to the closed or open position with a hand handle, and use a multimeter to measure whether the output voltage of the closed or open position changes. If not, the hall switch is broken. 3. Poor contact between the switch and the loss of control box plug-in: open the channel gate and use a meter to measure whether the positive and negative voltage of the photoelectric switch exists. If not, there is a problem with the connector and it must be checked. The section screws are connected with positive and negative threads, and the upper and lower bearings are connected with double headed screws. If the screws are loose, the upper and lower positions will be inaccurate.

Insert an 80mm long #4 iron bar between the double headed screws and rotate to adjust the upper and lower sword positions of the brake rod. If the screw is loose, the upper and lower positions of the brake rod will be inaccurate and the rod will shake greatly when stopping. Hang the bolt tightly and lock the nut. Cimin Hall elements are used for up and down in place. If the position of rectangular magnet and disc with cam of reducer changes, it will cause inaccuracy in place.The problem can be solved by adjusting it accurately without scraping. When the local induction coil cannot be firmly fixed in the nest, the vibration of the vehicle over the road will cause the coil in the nest to deform and change the initial inductance of the ground induction. At this time, the sensor must be reset before it can work normally. The solution is to pour the melted asphalt into the to fix it.
