My swing autogate almost same condition. Can open but sometimes cannot closed. Try to manual swing the gate . Is it very hard to swing?

If not, can you hear the relay sound when you press the remote?

DC Moto remote is running frequency so u hv to press a bit long for the board to receive the right signal, normally 2 second will do. Anyway their new remote is a bit troublesome now days after using for some time hv to knock a bit to get it working. The battery joint seem to be not connect properly, hmmmmm. Anyway their motor system are reliable. But now mostly ppl will go for Dnor Turbo 880 much easier to link to third party module.

Another way to know the board receive command or not is to activate the alert. The system will beep whenever the board receive command signal when alert is activated.

Ha Ha Ha just adjust the stopper at the bottom of the motor.
It's better to get installer who can provide full instruction on how to use and DIY trouble shoot minor problem. DC Moto 925W and Dnor Turbo 880 hv more feature which must be explain properly after installation. This model are not like those normal arm model which open one or two side then close that's it. For us we will need to spent at less another 30 mins to explain on how to use the system.

That's why a lot prefer cheaper installer then those who able to provide proper installation and explanation after full installation.

Since hv rubber stopper then no need to worry when closing. For open turn cylinder stopper facing out side all the way to the end then push the gate until where u want it to stop opening and turn the cylinder stopper to touch the corner of the arm end so it will prevent the arm from moving anymore. After doing it for both side just press remote to open close the gate. That's how u control where the gate stop when opening and not until it hit the pillar like those under grd old system. If u dun adjust it now and let it keep pushing on the pillar end of the day u hv a broken gear bottom part soon.

Actually all the instruction is in the white pc of installation paper.

There suppose to screw on the cylinder nut on both side screw to control where the gate suppose to stop.

Ha Ha Ha that's a first. Yeah that's what u need to do dismantle all and fix back the right screw at the right place.

Hi, is your problem solved? I dont think so its the stopper problem. Installer installed the arm bracket not long enough, probably did not measure it properly. IMO need to shift the arm bracket further out by 1" to adjust so that the black part cant be seen. 

Great! yup, required is 64.5cm. lol. probably installer was in a hurry?  It will last because 64.5cm is their recommended length. I've installed a few and no complaints so far. The only complaint I had was motherboard spoil due to lightning strike, after that is okay already.
