6-11(b) Modify the original program so that the panel mounted selector switch can be used to select one of the following three operating modes:

• When the selector switch is in position A, the process shall be virtually turned off with no outputs

being capable of being energized.

• When the sector switch is in position B, the process shall operate as the continuous filling program

of 6-11(a).

• When the sector switch is in position C, the process shall operate in such a manner that the boxes

will simply move down the conveyor continuously and bypass the fill operation.
