Question regarding the Apollo 635/636 Control Board


Question: Robert from California has himself a really interesting situation… I had an Apollo 635 / 636 installed in Jan./02. Gate began behaving very erratic. Batteries have been replaced and are fully charged. I am getting a very limited range on both keypad and remote, also when the keypad does function it will open when any number that is pushed.

Answer: Hi Robert, it sounds like you are having issues with your wireless system and not with your operators. May I suggest that before anything else you check the batteries in your keypad, in your remotes and please it is very important that you check the connections (including the antenna connection – COAX cable) on your receiver. Make certain that all connections are tight and free of corrosion or debris. If that does not help I would begin with the receiver.

Question regarding the Apollo 1600 operator and the 636 control board


Question: Armando has a little bit of a complicated issue: I have the Apollo 636 board and the Apollo 1600 dual door actuators. The doors get stuck open or in the retracted position. If I disconnect the primary actuator it will sometimes close, most other times if I press the led button on board, the gates will close. Do I need a new board or do I have problem with the primary actuator or maybe the free exit sensor?

Answer: Well Armando, I would not rush to buy a new board just yet. Before you do anything, my suggestion is to take out the battery and test the voltage under load. If you do not have a meter to do so, you can always take it to an auto parts store (PepBoys or NAPA) and they will test it for you free of charge. If the battery checks OK under load, all your connections are clean and free of corrosion and your peripherals (photocells, loop detectors and exit probe can be tested by simply disconnecting them from the gate operator) are in good working order… then you will probably need a new board.

Is the Apollo Gate Opener battery necessary if wired to 110VAC?


Question: Roy wants to know… My Apollo gate opener is wired to 110 VAC electric, which in turn is wired to a 12 volt battery. Does the gate open with 110VAC or 12 volt battery? Is the battery necessary if wired to 110VAC?

Answer: Good morning Roy, yes it is necessary, your Apollo is indeed a 12VDC operator and everything runs off of the battery. The 110 VAC is for the trickle charger which keeps your battery charged and conditioned so that your operator can run. You can conceivably replace the electric charger for an SG-4 and a solar panel (or panels, depending on how much use the operator gets) and have a fully solar system.
