Possible Causes
Solutions
Falling barrier arm
suddenly rises in
the midway.
If the F3 value is smaller than
25, bacause of the high
rebound sensitivity, barrier
arm inertia or wind might
cause this problem.
Adjust the rebound value F3 to 50.
Spring is too tight.
Loosen the spring.
The barrier arm
cannot be
controlled up and
down, while the
control board LED
displays error code
E1.
If the barrier arm cannot rise
during power-on, but the
control board LED displays
the movement angle value
when you manually rise the
barrier arm, it means that the
motor is damaged.
Replace the motor.
