Question: My Apollo 1500 will not auto open when we have a spell of really cold weather


Question: Jimmy has an interesting problem he needs help solving… I have an Apollo 1500 gate operator and my gate will not auto open when we have a spell of really cold weather. The sensor is buried and it will not work at any depth during cold weather… What can I do?

Answer: Hey Jimmy, per your recent email enquiry, it appears that what it giving you the problem is your exit probe, and unless the temperature has been dropping below -5 degrees Farenheit (which is the tolerance value of the EMX-202S probe) what you have is a defective exit probe. You do have other alternatives to the exit probe which are reliable, but non would be as simple to install.

Issue: I am having an issue with readjusting the open and close limit of the Apollo 7300 ETL Operator


Question: Hector wanted to know about his Apollo operator… We have a 7300ETL opener and I am having an issue with readjusting the open and close limit. It appears, cold weather somewhat messes up the cycle when opening my gates.

Answer: Hello Hector, the good news is that the model 7300 from Apollo is rarely affected by weather, especially the limits as they are magnetic reed switches with the actual magnets physically bolted to the chain as you can see on page 11 of the installation manual.

What this means is that neither rain nor shine nor sleet or snow will affect its ability to work or the limits and unless your chain has been cut, they will always stop in the exact same place. However with that being said you may want to check the actual limit reed switches or call a gate maintenance company that can check your charging system and control peripherals.

Second question from Hector: Thanks for your quick and helpful reply. After reading your message, I read something that the installer did not include in the install. That was the magnets for the closed and open limits. I was guessing that these functions were programmed into the system, that apparently is my issue, and the reason why I cannot set the open limit and my gate just wants to go on, plus the gate overworks and then will not come on. Please advise.

Answer: Hello again Hector, please contact me directly and I will be more than happy to give you a quote on the limits and the magnets you need.

Question regarding Apollo operator not closing gate in weather below 45 degrees


Question: Tom has a small problem… I have an Apollo Gate Opener, with control board (model 635) which was installed a little over a year ago. The controller will not close the gate when the air temperature drops below 45 degrees. Please advise what I need to do to correct this problem?

Answer: It sounds as if one of your peripherals (photo cells, receiver, or other safety device) is acting up in the cold weather. Check that all photocells are clean and clear of moisture in the lens, other than that if you have a loop or any other device you may want to look at or even take a photo of your control board so we can determine which input is holding it open by the LED’s that are lit on your board.
