  • Low power control system for an elevated work platform
    Patent number: 9527713
    Abstract: A control system optimized for low-power operation includes an electronic valve controller for controlling a hydraulic valve and a control interface for receiving operating commands from a user and communicating the operating commands to the electronic valve controller. The control interface includes a multi-function single hand control with a plurality of position indicating elements for detecting actuation of the single hand control, a master enable associated with all of the position indicating elements, and a plurality of individual enable elements each associated with one of the position indicating elements. A controller directs operation of the control interface and is configured to sample a position indicating element only if the master enable is asserted and the corresponding individual enable element is asserted. Other aspects of the control system minimize power consumption, including fast sampling that allows the controller to spend more time in a low power mode.
