Abstract: The present disclosure relates to a system and method for arbitrating between joystick inputs. The system generates a first command based on the first input if the first input has a non-zero value, and generates a second command based on the second input if the first input has a zero value and the second input has a non-zero value. The system thereby allows two different inputs to control a single commanded function.

Abstract: A computer-based method for calibrating a solenoid-controlled excess flow control valve that couples a first hydraulic circuit to a second hydraulic circuit is provided. The method includes determining a start-of-flow current at which hydraulic fluid begins to flow, closing the valve, sending an actuator command to the second hydraulic circuit, determining a first flow through the hydraulic actuator, opening the valve by setting the solenoid current to a calibration-flow current, sending the actuator command to the second hydraulic circuit, determining a second flow through the hydraulic actuator, calculating a flow difference, determining a calibration-flow valve command associated with the flow difference, determining a maximum-flow current based on the start-of-flow current, the calibration flow current, and the calibration-flow valve command, and creating a valve calibration table based on the start-of-flow current, the maximum-flow current and a valve response table.

Abstract: An overspeed protection method for a machine having an engine drivably coupled to a pump is disclosed. The method includes determining a speed of a rotatable component connected to the engine based on an engine speed and determining a minimum power limit based on the speed of the rotatable component. The minimum power limit corresponds to a minimum power required to retard the engine in order to prevent an overspeed condition of the rotatable component. The method further includes determining a minimum flow limit based on a predetermined relationship between the minimum power limit and the minimum flow limit. The minimum flow limit corresponds to a required flow of the pump in order to provide the minimum power limit. The method further includes regulating the pump in order to achieve the minimum flow limit.

Abstract: Cylinder sensor assembly includes a sensor with pressure pipe extending from the first sensor axial face of a sensor body, an annular face seal adapted to be disposed between the first sensor axial face and an endcap external axial face, and a sensor retention assembly. The sensor retention assembly includes a plurality of fasteners and a retainer body having a retainer distal face, a plurality of through holes and an internal chamber with a radially-extending flange extending into the internal chamber with the internal chamber open to the retainer distal face. The sensor body is disposed within the internal chamber adjacent the radially-extending flange.
