Abstract

A control system for a machine and the like having at least one cycle made up of at least two events utilizes at least one momentarily operable switching device to actuate the cycle and digital circuitry including a plurality of NAND and AND gates to implement a momentary zero potential signal produced by the switching device. The control system includes a control circuit having programming means, digital circuitry further including at least two NOR gates for latching the control circuit in various modes of operation, and timing circuitry for deriving a selectable timing period for at least one event of the cycle; and gate circuit means including additional digital circuitry for regulating at least another event of the cycle in response to the control circuit.
