  • Fault detection system with leakage current detection
    Patent number: 9234931
    Abstract: A fault detection system for a machine having a plurality of electrical conducting elements insulated from a frame ground of the machine is disclosed. The fault detection system may include a high voltage DC power source, a positive high voltage bus connected to a positive terminal of the high voltage DC power source and providing high voltage electrical power to the plurality of electrical conducting elements, and a negative high voltage bus connected to a negative terminal of the high voltage DC power source and returning high voltage electrical power from the plurality of electrical conducting elements. At least one of the positive and negative high voltage buses may be selectively connected through a plurality of switches to plural zones of the electrical conducting elements, with each of the plural zones being electrically connected in parallel, and selectively connected to the high voltage DC power source by one of the plurality of switches.

  • Paving machine with operator directed saving and recall of machine operating parameters
    Patent number: 9045871
    Abstract: A paving machine including an adjustable screed assembly is provided. Actuators adjust the screed assembly into the plurality of different configurations. Sensors sense a respective configuration parameter indicative of the configuration of the screed assembly. A controller is configured to save a first set of parameters including the configuration parameters and save a second set of parameters including the configuration parameters in response. The controller is configured to recall one of the first set or second set of parameters, and adjust automatically the configuration of the screed assembly to correspond to the configuration parameters included in the recalled first set or second set of parameters.

  • Screed extender speed control
    Patent number: 8979425
    Abstract: A control system for an extendable screed includes a first input device configured to set a speed limit for the extendable screed, a second input device configured to vary a speed of the extendable screed within the speed limit. The controller further includes, a third input device configured to govern a relationship between a speed of the extendable screed and a relative position of the second input device. The control system further includes a controller configured to receive inputs from the first, the second, and the third input devices and output a command signal to move the extendable screed relative to the main screed.
