SmartFade ML fader issue.

I just came into a space using a SmartFade ML, turned on the board, cleared the stack, and reset the patch 1:1.  Went to work with the lights and found that the faders do not bring up the lights at all. The bump buttons still work, however. I have checked the blackout and solo buttons and both are off. I'm not sure where to go from here, having limited experience with this board.
