BFT Gate issue

[Automatic-TC]

Hello,

Firstly great website, been looking over to see if anyone else has a similar issue. Basically I've had two service companies out and its been quite painful trying to get an answer on fixing an issue. One of our gates doesn't close over properly and its on a new BFT Sub R (now its 2-3 year old) but we face this issue every time servicing comes around and ask for it to be fixed only for it to run on.

One of the gates doesn't close over properly. It drives against the stop but theres no force holding it closed. Infact its slack. In the wind its either held open at its maximum gap or held closed. A video below will probably show it much better than I can explain it.

Is this a case of the gate not being seated on the sub properly?

Any help would be greatly appreciated and would help keep a jack russel and border collie alive

it looks quite easy to fix it ,control board have to be reprograming once again .
tell me when this problem back again after service ??

i wtch this movie once again with sound this time ,im wonder why in a half way whole gate starting to shaking up ???

regards
