Sorry about the confusion, but I finally got to the job yesterday. I don't have time this morning to go into much detail, but what I found was that the r3 resistor door close wire was removed from the adjusting band and relocated to the end post on the r3 resistor to try to slow the door down I believe. The OHS wire was attached to r2 resistor which I moved to r3 and the open speed is much better,but I still have virtually no slowdown during door close. The previous mechanic had Csd1 and Csd2 cams almost aligned at about center of the door close, when I move them to there proper position the close gets worse? I have to go back again this week to check the resistor in the operator, I ran out of time yesterday.
This sounds to me that any resistance that should be in that circuit isn't there. Is it shorted, are the limits shorted? Doubt is open circuit as then it would most likely wouldn't close. Anyone got a door print they could post?
