I am looking for an adjustment sheet or instructions for an old Dover door Type D operator installed in the 70's. Some modifications have been made over the years and the decel is not working properly. The elevator is a 4 stop hydro and the controller has a door board with 2 pots on it. One is labeled re-open the other is not labeled. What is the function of the second pot?
Thanks for the help!
I'm confused(what's new), it has a board and a resistor. Pics would be greatly appreciated.
