Abstract
A system for controlling a hydraulic component. The system includes a control system configured to carry out a health check routine having steps of (A) fluidly connecting one of the hydraulic supply systems with the component until (i) a predetermined pressure is reached on the hydraulic supply side and/or the hydraulic return side, and/or (ii) a predetermined amount of time has passed; then (B) isolating the pressurised hydraulic fluid within the hydraulic supply side and the hydraulic return side so that hydraulic fluid leaks from the hydraulic supply side to the hydraulic return side via the controlled leakage; (C) monitoring the pressure of hydraulic fluid within the hydraulic supply side (S) and/or the hydraulic return side over time; and then (D) determining if the pressure of hydraulic fluid within the hydraulic supply side and/or the hydraulic return side follows a predetermined or expected pattern.
