Abstract:
A control circuit for controlling certain operations of a work machine based upon the fulfillment of certain operator conditions, said control circuit comprising:a first switch operable between a first mode of operation corresponding to a condition when a first operator condition is not fulfilled and a second mode of operation corresponding to a condition when the first operator condition is fulfilled;a second switch operable between a first mode of operation corresponding to a condition when a second operator condition is not fulfilled and a second mode of operation corresponding to a condition when the second operator condition is fulfilled; andan electronic controller coupled to said first and second switches for receiving signals therefrom, said controller being operable to receive a first signal indicative of when said first switch is either in its first mode of operation or said first switch is not in its first mode of operation and a second signal indicative of when said first and second switches are either concurrently in their second modes of operation or at least one of said first and second switches is not in its second mode of operation;said first signal being grounded when said first switch is in its first mode of operation, and said second signal being grounded when said first and second switches are concurrently in their second modes of operation,said controller being further operable to control the certain operations of the work machine based upon said first and second signals.
