Introduction to the installation method of electric control lock

Introduce the concept of electric lock before installing the electric control lock. The terminal of the electric lock is actually an electromagnet, which controls a simple mechanical device to switch the door. However, the action of the electromagnet is acted upon by a series of commands. When there is no control, first measure the voltage to the electromagnet, and input the switch door command (some are electromagnetic card, some input password), to see if the voltage changes, if there is a change, and the electromagnet does not move, The fault is the electromagnetic control part, and the electromagnetic control part should be repaired or replaced, otherwise the control part is faulty. The control part is more complicated. It has two parts of hardware and software for control, and some are connected with computer interface, which can perform personnel access query statistics. The general control output voltage is controlled by the relay output. First, see if the relay has a sound of suction. If not, measure the voltage of each part of the relay control interface and whether the drive device is damaged. If it is intact, you can further measure the working voltage of the integrated circuit, reset the port and the clock oscillation part. If there is no problem, Generally it is a software failure, which can only be contacted by the developer. If the relay has a pickup sound and the voltage of the relay is normal, the relay contact is damaged or the line to the electronic control part is broken.

Electric lock installation

According to my installation experience and teaching experience in Zhengzhou North School to help you analyze, you should say that the installation of the central locking.

First of all, many cars are now in the original car. If the installation is very simple, the following requirements are required: 1. The motor of the five wires is the main motor mounted on the main driver's door, and the other two-wire motors are each door. (There are three remaining doors) one, and finally all the motors are fixed; 2. Connect the motor motor to the lever or button (opening handle) on the original car through the wire to ensure that it can operate freely; The motor harness is smooth, the plug is firmly connected and the harness is arranged, and it can not be leaked outside. 4. Place the central control box under the instrument panel on the main driver side and fix it. Connect the plug. 5. If the iron is used, the general anti-theft device If you connect the brown and white wires to the immobilizer, this is the switch signal.

Finally, by operating the main driver motor, the other motors follow the action.
