Reasons and Elimination of Common Faults of Switching Power Supply in Parking Lot Card System

In the parking access control card system, the swing gate is used as a heavy pressure device in the channel management system. Whether it can operate normally or not determines the normal passage of the community personnel and the important guarantee for the strict management of personnel entering and exiting. During the use of swing gates, we often encounter inexplicable end-power or failures such as normal operation. This is due to the fact that the swing gate may cause swing due to unstable power supply or power failure. If it can't work normally, Ruifangda is a professional manufacturer of access control parking lot system. Here we have summarized several troubleshooting methods for the common faults of the pendulum brake and power failure, hoping to help you in the future maintenance of the swing gate. 1. When the swing gate is powered off, the swing swing arm does not operate normally and the swing arm is not limited. After the power is restored, the swing arm is reversed.
The solutions are:
1. Check the battery voltage (not less than DC9V);
2. Detect left and right open-position limit photoelectric switches and motherboards, respectively.
3. Check if the circuit is loose or disconnected, and check the voltage output (DC12V) of the MA and MB terminals of the CON1 terminal of the power-down control board, otherwise the power-off control board is damaged;
4. If the clearance of the movement is too large, the swing arm will cause the light block to move. After the swinging power is turned on, the limit signal is not detected and the Motor is reversed. It is normal to block the optocoupler on a lower limit photoelectric switch with a dark opaque object.

2. After the power is turned off, the gate brake will not operate and stop moving.
The solutions are:
1. Check whether the gate line is loose or off;
2. Check whether the voltage of the dry battery is normal (the voltage is not lower than DC9V);
3. Check the voltage output (DC12V) of MA1 and MB2 terminals of CON1 terminal, and check if the power failure control panel of the swing switch is damaged.

The above is the common two troubleshooting methods after the power switch is turned off. Of course, if a swing fault occurs, it is best to contact the manufacturer's technician first to help.
