Hi All,
I don;t know if this is an ACP issue or a PMX issue or where to look for a solution.

I am trying to do post imaging flats from a EL screen. Everything work well up until the program attempts to start the flat session. See error below: Note; flatman, and roll off roof work properly via software control. I do not request a roof close. A roof closure would be OK if the program did not shut down. Any help with this is appreciated.

I have not requested the Session program to close the roof but it does and I don't know why. (Red notes below are my comments and this is not included in the program code)

Equipment PMX, Foster Systems roof controller, ACP 8.0 Build 5. MS 7
