<p>A method of operating a control valve assembly 26 for a hydraulic system 20 includes detecting the current operation of a first position sensor 44 and a second position sensor 46 to determine if at least one of the first position sensor 44 and the second position sensor 46 is inoperable. A pressure of the fluid at a first work port 36 and a second work port 38 is measured, and one of a first valve 40 and a second valve 42 is actuated when one of the first position sensor 44 and the second position sensor 46 is determined to be inoperable. The first valve 40 is actuated based upon the fluid pressure measured at the second work port 38 to adjust the flow of the fluid through the first work port 36. The second valve 42 is actuated based upon the fluid pressure measured at the first work port 36 to adjust the flow of the fluid through the second work port 38.</p> |
