1. What is the failure of chatter during the operation of the barrier?
The chattering in operation is mainly due to the fact that the length (weight) of the brake lever 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.
Second, the barrier can be closed (open) can not be opened (off)
Can be turned off (on) can not be opened (off), indicating the motor white public line is good, you can first measure the motor red (yellow) color and white line is the same, and then measure the blue and gray (green) color signal line and K2 (K1) Whether the sensor switch is short-circuited.
Third, can switch but can not stop can switch Description The motor line red, white, yellow three lines is no problem, the signal line is not short circuit. The main reason is that the limit signal is not sent to the controller or the controller limit function is bad.
Fourth, the barrier can not stop automatically 1. Limit sensor K1, K2 at the same time open (limit sensor is a magnetic field is closed, no magnetic field);
2. Public line blue circuit.
3. Bad Controller: Use the same inspection method as above to measure.
Fifth, the gate can not take off and landing
1. First check whether there is electricity, whether the fuse has burned, if the fuse is broken, you must do a full inspection.
2. Unplug the underground cable plug in the communication room and use a 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, and the yellow and red should be 30 ohms. Left and right), and then use the R×10K file to measure whether or not there is a certain resistance with other lines (mainly to check whether 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.
3. The motor lead is only red and yellow, and the white is unreasonable. Check whether the motor stator is hot. If it is hot, it means that the thermal shutdown of the motor can not be switched. If it is not hot, check whether the 20UF starting capacitor is invalid.
Xiao Bian concludes: The above introduced the parking lot maintenance knowledge, we hope to help everyone. For more relevant knowledge, please continue to pay attention to this website information platform. Follow-up will present more exciting content for everyone.
