Fault 1: After the power is turned off, the gate brake does not operate and stops.
Solution:
1. Check the battery voltage is normal (voltage is not lower than DC9V);
2. Check the gate line is loose or off;
3. Check the voltage output (DC12V) of the two terminals MA and MB of the CON1 terminal, and determine that the power-off control board of the swing switch is damaged.
Fault 2: After the power switch is turned off, the swing swing arm does not operate normally and the swing arm is not set. After the power is restored, the swing arm is reversed.
Solution:
1. Check the battery voltage (not less than DC9V);
2. Check if the circuit is loose or disconnected. Check the voltage output (DC12V) of MA and MB of the CON1 terminal of the power-down control board. Otherwise, the power-off control board is damaged.
3. Detect left and right open-position limit photoelectric switches and mainboards, respectively.
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.
The above are two common troubleshooting methods after a power failure. I hope to help you. If a swing fault occurs, it is best to contact the manufacturer's technician directly for assistance.
