Turns out that the change I made above didn't have a positive affect on flat production. In fact, flats didn't run at all. As another solution I tried to use the web forum to submit a flat plan. I'll run the testing procedure this afternoon, but this generated yet another question. The plan generated does not include rotation angle even though it's specified.

Well, I'll answer this myself...the rotator must be connected in ACP otherwise the PA doesn't get picked up.
