ABSTRACT:
The apparatus and method for contiguous valve control. This involves the inputting of data for each of a series of valves then comparing that digital valve activation data in a one and one correspondence to the digital valve activation data that was inputted to that same series of valves in the previous machine cycle. If a particular valve was turned on in the previous machine cycle, then this valve will not be applied with voltage for a percentage of the valve's machine cycle time. There is a first circuit for generating a first voltage pulse of a first period of time, a second circuit for generating a second voltage pulse, a third circuit for generating a third voltage pulse, a fourth circuit for generating a fourth voltage pulse for a second period of time, a fifth circuit, coupled to the second circuit, third circuit, and fourth circuit for generating a fifth voltage pulse for said second period of time when the second voltage pulse and the third voltage pulse and the fourth voltage pulse are present, and the first circuit and the fifth circuit are coupled to a valve drive circuit for activating said valve for a first period of time with said first voltage pulse and deactivating said valve for a second period of time during said first period of time with said fifth voltage pulse.
