How To Install Automatic Gate Opener Properly With Ease

An automatic gate opener is an automatic arm which has the ability to open and close the gate.

The opener has an onboard circuit that will tell your gate to open, reverse or close as needed when it receives a signal from a remote control. But make sure you follow the safety guidelines when installing the gate openers.

It is through proper installation that you are assured you will have a problem-free operation of the gate.

Connect a solar panel or a transformer to the opener’s control board to keep the battery charged. Keep in mind DO NOT CONNECT the solar panel and the transformer to the control board at the same time. It will cause malfunction of the control board.

Measure the gap between the control box and the AC outlet. Take note of the length and cut the wire. Place the wire in a trench from the electrical outlet to the control box and then bury the wire.

Wire to be connected to the control box should be run into PVC conduit to keep it protected against animals, weed eaters, and others. With the wire on the PVC conduit attach it to the power terminals on the control board.

Connect low voltage wire from the AC outlet to the transformer terminals. Plug the transformer into the AC outlet. Use a weatherproof housing/cover if the transformer is connected into an outdoor outlet.

The gate opener package includes an entry transmitter that you can use to set the control board’s closed position limit. You can check the Instruction manual for details about programming the closed position limit.

Step 11 - Set The Stall Force Setting 

The obstruction sensitivity is controlled by the stall force potentiometer. The obstruction sensitivity is the force the opener will apply when the opener encounters the problem before it automatically stops and reverses its direction.

To adjust, use a screwdriver from the minimum factory set up to the point where the gate moves smoothly and without interference from its normal wind conditions and weight.

Step 12 - Program The Auto-Close Timing

To set how long the gate will remain open before it closes, adjust the close timer on the control board from 3 to 120 secs. or to off.

Step 13 - Set The Transmitter Code/Settings

Change the security settings of your transmitter by changing them from the factory code. Remove the transmitter cover and set the dip switches into a combination of switch positions.

After adjusting the dip switches, you will program them into the control board following the instruction indicated in the manual.

Step 14 - Set Up The Warning Signs

Setup the warning signs included in the kit. Position these warnings on both sides of the gate.
