Abstract
Almost all industrial machine controls consist of sequential circuits and one or two fringe condition modules. The most commonly encountered modules are the cycle-selection module, the emergency-stop module and the two-hand start module. This last is a combinational-type module and should not be designed by circuit designers unless they know the precise requirements stated for such circuits by their local industrial safety authority (specifications vary from country to country). Fringe condition modules interrupt, condition or prevent either continuous cycling or the normal sequence program of sequential control circuits.
