I'm going to start this thread to provide reference information for some future poor soul who may have to service one of these systems. Hub is no longer around, and information about these systems and dimmer modules does not exist. As such, over the next few months I am going to have to reverse engineer the equipment and create my own schematics. The system consists of an analog controler mounted in a wall. It has seven dimmers and a master, as well as an up/down motor controler for the bulk of the building's lights. Up in the hot attic is a cabinet containing 18 modules, each 3.6Kw. (and a tiny little motor attached to a pot!) It has been in use for 28 years 24/7. Amazingly, it still works pretty well, although the curves are trash at this point. I am suspecting this will involve massive capacitor replacement.
Today I started with the controler and had my first surprise! The controler outputs 0 to -24 vdc! Yes, Negative!
I will post back as the project continues.
