Intelligent barriers are specially used to restrict the entrance and exit management of motor vehicles. They are widely used in highway toll gates, parking lots and other vehicles. The intelligent barrier can be realized by wireless remote control alone, or it can be automatically managed by the management system. The barriers are divided into functions: straight arm barriers, folding arm barriers, fence barriers and advertising barriers. How to solve the failure when it is used normally?

　　The barrier may have the following faults:

　　1. The gate bar cannot be lifted or lowered

　　1. First check whether there is electricity, insurance, etc., and a full inspection must be done.

　　2. Measure whether the motor is short-circuited. 

　　3. Whether the motor is running and whether the capacitor is invalid. 

　　4. If the motor has no problem, check whether the switch can be used, and then check the limit.

　　5. If there is no problem with the motor line and the signal line, it still cant be turned on or off, indicating that there is a problem with the control box.

　　2. The barrier can be closed or not opened

　　If this is the case, check the signal line and sensor switch for short circuits.

　　3. The barrier can be switched but not stopped

　　It may be that the limit signal is not transmitted to the controller or the controller function is damaged.

　　4. The gate cant stop automatically

　　The controller has a problem

　　Fifth, the gate often shakes during the operation

　　Check whether the tension between the road bar and the spring is installed correctly and is proportional.

　　Sixth, the gate bar of the gate keeps in place

　　The SCR in the control box is damaged

　　7. The barrier does not run after power on

　　This shows that there is a problem with the capacitor or the motor

　　8. There is noise in the barrier chassis

　　Check whether the bearing and link parts are normal.

　　Simple faults can be checked by the above methods, such as the inspection or maintenance of the motor and internal accessories in the chassis, or ask a professional to avoid accidents. Various faults will occur during the long-term use of the barrier, which should be discovered and resolved in time.
