Abstract
A speed control system for a device includes a microprocessor based module for established a window or speed range having an upper and a lower speed limit. Operator control of the speed of the device is permitted within the window. In a first mode, a windowed comparator is engaged immediately that the device speed attains the lower limit of the established speed range. In a second mode, the device speed must be substantially constant at a speed within the established speed range for a predetermined time before the windowed comparator is engaged.
