Abstract: A sensor calibration system includes a controller configured to receive a first electrical output generated by a sensor while submitted to a first input condition and a second electrical output generated by the sensor while submitted to a second input condition. The first and second electrical outputs represent lower and upper limits, respectively, of a sensor measurement range. The controller obtains a first reference value that corresponds to the lower limit and a second reference value that corresponds to the upper limit, and determines a drift function of the sensor based on a value of the first electrical output, a value of the second electrical output, the first reference value, and the second reference value. The controller inputs a value of a raw electrical output generated by the sensor into the drift function to determine an adjusted value of the raw electrical output.

Abstract: A system is provided that includes one or more sensors configured to monitor operating parameters of engine components and a controller. The controller is programmed to perform operations that include displaying test details on a display screen that are specific to a selected test to be performed on the engine components. The test details include pre-conditional parameters of the engine components that are necessary prior to starting the selected test. The operations also include receiving the monitored operating parameters of the engine components from the one or more sensors and determining whether the monitored operating parameters satisfy the pre-conditional parameters. The operations further include, responsive to receiving an indication to start the selected test and determining that the measured operating parameters satisfy the pre-conditional parameters, performing the selected test on the engine components.

Abstract: A system includes one or more sensors that generate sensor measurement signals based on characteristics of one or more components of an engine control subsystem. The system also includes a controller circuit having one or more processors. The controller circuit is programmed to perform operations in response to instructions stored on a non-transitory memory. The operations performed by the controller circuit include acquiring the sensor measurement signals from the one or more sensors. The sensor measurement signals include electrical characteristics. The operations performed also include comparing the electrical characteristics of the sensor measurement signals with operational threshold corresponding to the one or more sensors, determining a set of candidate sensors having a fault based on the comparison, and displaying a troubleshoot window based on a select candidate sensor.

Abstract: In one embodiment, an engine management system (EMS) can use a human machine interface (HMI) to modify operating parameters of a set of engine generators controlled by an engine control unit (ECU). The HMI can permit authorized users to adjust a plurality of operating parameters of the engine generators in accordance with an authorization level of the authorized users. The ECU can be a standalone system operable independent of the EMS. A communication network (e.g., ARCnet) can link the EMS to the ECU, wherein the changes of the operating parameters input via the HMI are maintained over a power-cycle of the EMS. Further, changes of the operating parameters input via the HMI can be maintained even when communications over the communication network linking the engine.

Abstract: A method of determining fuel limits for an engine includes measuring an actual fuel value for the engine and creating a plurality of engine speed points. The method further includes calculating respective static fuel limit points for each of the engine speed points utilizing the actual fuel value. The static fuel limit points define and limit a rated power of the engine.
