FAQ Appendix 1
1. 1. Power on the boom gate, open or close it by remote control. The boom does not work.
Check whether the controller power indicator is on. If not, check whether the fuse is in
good condition.
Check whether the remote control matches with the boom gate, or the battery is low.
There is frequency interference near the remote control. Press the control button on the
controller to check whether the boom works (if there is no button, short COM, Open and
Close).
External protection circuit failure, or the circuit is in a protected status. Check whether the
radar indicator and the coil indicator are on.
2. The boom gate stops finding the up and down limit in the closing process after power-on.
Check whether the boom is installed. When the spring is installed, the boom gate cannot work
without the boom.
3. The boom gate opens and closes too fast after powered on for the first time.
Check whether F-13 power-on self-learning speed is too great. If yes, reduce the 1-XX and 2-XX
values of F-13.
4. The bar cannot be in place when manually locating the limit position, and the buzzer will
alarm.
Check whether F-13 power-on self-learning speed is too small. If yes, increase the 1-XX and 2-XX
values of F-13, and try again.
5. The controller displays IDLE.
Check whether motor sensor plug is inserted. If not, insert it.
Check the motor sensor, and replace it if it fails.
6. The controller resets when the boom gate is running.
Check whether there is short circuit inside the motor. Measure the phase line resistance
with a multimeter.
Check the controller, and replace it if it fails.
7. The boom gate automatically opens during the closing process.
Check whether F-15 sensitivity of boom is too small. Increase the value.
Check whether coil or radar has abnormal signals by checking whether the coil or radar
signal indicator flashes abnormally.
8. The boom dithers obviously when the boom gate is opened in place.
Decrease F-06.
Decrease F-06 and F-02.
Decrease F-00.
9. The boom dithers obviously when the boom gate is closed in place.
Decrease F-07.
Decrease F-07 and increase F-03.
10. The remote control distance is too close.
Check whether the battery voltage of the remote control is too low. If yes, replace the
battery.
Check whether there are power lines or severe electromagnetic interference nearby. If yes,
replace the remote control with a high-power one.
