Abstract:
An electronic sequencing system comprised of two groups of three identically operating sequencers and circuitry that combines the outputs of these sequencers so that accurate, flexible and reliable sequencing of devices is obtained. Each sequencer is comprised of a microprocessor, memory, and peripheral circuits. The individual sequencer outputs are combined such that at least one of the corresponding system outputs will activate the device to be sequenced if at least two of three corresponding individual sequencer outputs signal that the device should be activated. Additional reliability is obtained by combining the outputs of each group of the identically operating sequencers to control the devices to be sequenced. Reset circuitry is also provided to simultaneously reset the sequencers and to prevent premature outputs from activating the devices to be sequenced.
