Garage door will not shut down.?

I have a 710 Allister garage door opener. The chain emerged from the arts, so off the chain in order to get back into gear. Now the door does not stop when you open or close until you press the button. Did I mess on the cam chain when I stood new chain? I tried to move them to resemble the installation on the door of my other but nothing seems to help. I found the problem! There are 2 types of fishing gear on the top of the opening, a device of great interior and exterior of a minor art. I had the chain around the outside only small gear. When I removed the chain I could once again see that the train had come inside out of alignment with the external computer. When the two gears mesh with the chain the engine stopped running in the top and lower and everything works fine. I also pulled the chain to prevent a fall of Sproket.

There is a limit switch to open engine that when the garage door is in the full up or down. When the chain jumped the track, he sent this limit does not come out of adjustment. When the door reaches the position down, closer thinks the door is still open. When it hits the bottom, is thought to strike an obstacle instead of being closed and changes direction. The same happens when it reaches the stop in the fully open position. Once more, think that the closer the obstruction is a stop and reverses direction. With the latest opener garage door, when they sense an obstruction, immediately reverse direction. This is a safety feature to prevent injuries. This change has to be adjusted. Check your owner's manual. to be the procedure to properly adjust the limit switches.
