Hi
I have replaced the normal photocells that come with the liftmaster openers and the cb11 control with the above photocells. The original photocells had only two wires so there was no problem wiring them up but the new ones have 5 and 3. I just wired the +/- to the cb11 as before but they do not work. They do click when you walk through them but this does not stop the gate from closing like before. The gates will open and close ok but the photocells are not doing their job. Does some of the other of the 5 connections need to be made and if so where are they connected on the cb11. If they are wired ok is there anything else that could be the problem?, I have done the learn photocells detail on the controller but it dosen't seem to help.
Thanks for any help
