An interlock system acts in conjunction with an arrangement in which selected ones of first and second pluralities of equipment for conveying chemicals are interconnected in accordance with a chosen operation of a process or apparatus. A separate information carrier corresponds to each piece of equipment of the first plurality and a control unit corresponds to each piece of the second plurality. The interlock system establishes an appropriate set of operating parameters for the chosen operation when the information carrier which corresponds to the interconnected first piece of equipment engages the control unit corresponding to the interconnected second piece of equipment.

An interlock system for establishing a different set of operating parameters for each of a number of different operations of an apparatus, each of said operations requiring the interconnection of different pieces of equipment selected from first and second pluralities of said equipment pieces, each of said parameter sets being designated by a different multi-digit binary code; said interlock system comprising: a movable information carrier assigned to each of said first, plurality of equipment pieces, each of said carriers containing information representative of a different one of said codes; a control unit assigned to each of said second plurality of equipment pieces; each of said control units including signal circuit means and further including signal probe means responsive to the information on said carriers for connecting or disconnecting said signal circuit means; means for positioning the assigned carrier and control unit of each pair of equipment pieces, selected for interconnection pursuant to a chosen operation so that the information on said assigned carrier is placed proximate the probe means of said assigned control unit clear of any intervening structure; and means for deriving a binary output signal from said signal circuit means representative of the code on said assigned carrier, said output signal being effective to establish a set of operating parameters applicable to said chosen operation.
