I am absolutely taking it as an insult!I appreciate people taking time to try and enlighten me but keep your snotty comments to yourself. I have been in the business for 26 years and I am the first one to admit I don't know everything, but I guess some people do. I am not on the job now and I will send pictures when I get there Tuesday.
By the way the comment about the controller is accurate, it is a Dover Hydro, there are boards in the controller (power, door, car ,hall etc.), the are two pots on the door board only one of which is labeled and the door operator has 3 250 ohm resistors in the controller cabinet.
