1. Detect left and right open-position limit photoelectric switches and mainboards, respectively.
2. Check the battery voltage (not less than DC9V);
3. Check if the circuit is loose or disconnected. Check the voltage output (DC12V) of MA and MB of the CON1 terminal of the power-off control board. Otherwise, the power-off control board will be damaged.
4. If the clearance of the movement is too large, the swing arm will cause the light block to move, and 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.
Fault 2: After the power is turned off, the gate brake does not operate and stops.
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 the two terminals MA and MB of the CON1 terminal, and determine that the power-off control board of the swing switch is damaged.
Common Faults and Treatments after Switching Power Failure
Fault 1: The pendulum swing arm does not operate normally after the power switch is turned off. The pendulum arm is not limited. After the power is restored, the swing arm is reversed.
