Whenever ColMon is moved:
    
    Collimator A (40min) and then Collimator B (60min) are moved to achieve the desired
    collimation (they cannot be moved simultaneously).  Here are the positions of the
    collimators based on ColMon's destination:
        None:  A and B are OUT
        24min: A and B are IN
        40min: A is IN and B is OUT
        60min: A is OUT and B is IN
