We claim:
1. An electronic control system for a compressor connected to a pressure system in which pressure is to be maintained within a desired pressure range by varying an output capacity of the compressor, the pressure system having a pressure sensor measuring pressure in the pressure system, and the compressor having a plurality of electrically actuated valves which can be selectively actuated to vary the output capacity, comprising:
input means for receiving operator input specifying a loaded pressure and an unloaded pressure, said loaded pressure and said unloaded pressure defining the boundaries of the desired pressure range;
processing means connected to the input means, the pressure sensor, and the valves, for: receiving signals identifying the specified loaded pressure and unloaded pressure; storing, for each of a plurality of pressure bands covering at least the desired pressure range, open and close values of each said pressure band, and storing information associating one or more of the valves with each said pressure band; receiving a signal from the pressure sensor indicating the pressure measured by the pressure sensor; determining for each valve a required valve status specifying whether the valve should be opened or closed, depending on the relationship between the open and close values of the pressure band associated with the valve and the measured pressure; and changing the open or closed state of the valves to match the required valve status of the valves; and
dynamic pressure band calculating means associated with the processing means for recalculating the open and close values of each pressure band whenever at least one of the input loaded pressure and input unloaded pressure are changed by the operator, such that the calculated open and close values vary with the loaded pressure and unloaded pressure input by the operator.
2. The system of claim 1 wherein the difference between the open value and the close value calculated by the dynamic pressure band calculating means for a pressure band varies depending on the difference between the loaded pressure and unloaded pressure input by the operator.
