If user wants to change side of arm on their own they should read instructions in User Manual, chapter 3.6.:
When changing side of arm it is possible that you will get DATA error on control board display and Gate will not work properly. DATA error means spring is not balanced properly after changing side.
You should do next steps to remove error:

3. If spring is not standing on 45° screw or unscrew spring manually until you get desired position
4. After adjusting spring lock arm (opposite of first step) and try to manipulate Gate with your App
