It is common that gate openers have separate receivers. If it happens that you do have these sources near you, then you will have to get a special receiver and an antenna.Ĭheck the face of your receiver cover. This could be a radio station, a military base, a flight path or an airport. Check to see if there is any possible source of radio transmitting near where you live. The other might be that some other source of transmitting is interfering with your source.Try to put it as high as you can and be careful not to let it touch any other metal surface. One reason might be the antenna which was cut or just shortened.The gate doesn’t open unless there is someone standing next to it This battery could be used on electronics on recreational vehicles or on boats and for lights.Ĥ. “Deep Cycle battery” is meant for long continuous small amperage loads. If it happens so that you need a new one, make sure you buy a battery which is rated for “High Cold Cranking Amps” and not the “Deep Cycle battery” because these “High Cold Cranking Amps” batteries are designed to provide maximum amperage for a short period of time, even when the battery and the weather is cold. There they will tell you if you need to buy a new battery or not. If all these steps did not help you and you still notice problems with the working of your gate opening mechanism, then I suggest you to take your battery out and take it to an auto parts store to be tested under load. You should check the trickle charger and make sure that it is charging properly.You can find this type of grease in any store for automotive parts. You will have to clean them and then apply grease which is specially meant for cold weather. Take care of the rollers and bearing surfaces.You should look for corrosion and if you happen to find any, you have to clean the terminals. Look at the solenoid switch and its electrical connections.Since Lead acid batteries emit Hydrogen gas during the charging process, the top part of the battery and the battery box MUST be vented to eliminate the hydrogen and prevent a disaster such as an explosion. WARNING - Never apply the Styrofoam insulation on the top of the battery!!! If your battery box is made of metal, then you should take some Styrofoam insulation and apply a thin layer of it onto the bottom and the sides of the box.Disconnect the cables from the battery and then clean the ends of the cables, as well as the battery terminals.If you follow the order of these steps, you will get an inexpensive solution to your problem. Luckily for all of us, there are several corrective steps that a person can take. If you hear a clicking sound coming from your gate, that is the indication that the battery solenoid switch is trying to close, but it can’t because the power is too weak. These actions create an internal resistance in the battery causing it to physically warm up from the inside, just enough to start the engine. The same thing happens when you repeatedly try to start the engine. When the engine won’t start because it is too cold outside, you can turn on your headlights for half a minute or a minute and then the engine will start. What happens here is very similar to what happens to your car when it is cold outside. Review: US Automatic Sentry 300 S Commercial Grade Automatic Gate Opener You may have noticed that if you try to open it a couple of times, it will finally work. This reaction is meant to produce the electrical current which allows the gate system to operate. Due to this, as the temperature gets lower outside, the internal temperature of the battery will also drop and this will make it harder for the battery to start because of the reduction of the electro-chemical reaction. All this makes it harder for the gate to move and open since it requires more power.Īnother problem is the battery since it is inside a metal box. Metal components will contract as the temperature drops and unless you are using grease specially intended for lower temperatures, the grease will thicken, too.
You might notice some delay in opening of your gate, or even the inability to open at all. There are several problems your gate might experience when the low temperatures strike. Problems due to cold weather and low temperatures
