I just installed a liftmaster commercial (medium duty). I got a 3 button wall controller with it. Wiring was as follows. Up = Green, Down = Blue, Stop = Red and a neutral = White. Everything works as it should. Now I came along afterwards and wanted to duplicate the function with and identical PB-3 wall controller about 70' away. I wired it identically to the original. I wired it in parallel with the original wiring (they are both wired directly to the head.)
It also works as expected with one exception: When I wire the second red (stop) button, then neither of the stop buttons work.
When I disconnect the second red (stop) wire both the open buttons and both the close buttons work as does the original stop button.
I tried replacing the original wall controller with the new one and it works just as did the original so I don't think it is the wall controller.
I tried replacing the red circuit wiring with another circuit in the same sheath and came up with the same results.
For now I have the original working with all three buttons working as expected and the second wall controller partially working (open and close buttons working with the stop button disconnected)
Additional Info: I experimented with it and found that either stop button would work if the other one was disconnected.
I suppose that it is obvious that I am confused about how to get the second stop button working. Anyone have any ideas? Thank You for taking the time to read this. Kind Regards.
