    Hey guys, I am an electrician on a commercial construction site and we are currently experiencing problems trying to dim a series of megabay Osiris wall lights, the lights are terminated correctly, we are receiving a negative 10v dc reading from the twin coming from the lights, but however we seem to have problems trying to control them with the 0-10v controller, I don't have much of an idea about the inner workings of the analog controller but if someone could help with a bit of an explanation that would be much appreciated. This is my first experience with a c-bus system. Oh and I have actually connected a potentiometer in between the twin coming from the lights and was able to dim them varying the resistance. Please help, and thankyou :).

    Wire the 0-10V output so that the 0V side is connected to the Megabay 0V side, and the +10V side is connected to the Megabay +10V side.

    The megabay lamps should not be putting out -10V, measure it the other way, you should then have +10V. Match the polarities and try that. (Do an experiment first!)
