Working on a Van Dorn pathfinder control. Hold was not giving us what we asked which was 1100 hold pressure for 9 sec. Pack was not being used at all.I turned it on by setting it at 9 sec and the only setting for pressure was low, medium, or high. As soon as I turned that on the hold graph hit every set point for the hold pressure. Does anyone know if the pack pressure settings run off of the hold settings or is there a page where I can control it separately. Thank you
