    Abstract: A system includes a control module and a monitor module. The control module selectively operates a component of the system in an ON state. The system receives power from an electrical grid. The monitor module selectively detects a fault event of the electrical grid in response to (i) an amount of current drawn by the component or (ii) a voltage of power received by the component. In response to detecting the fault event, the control module switches the component from the ON state to a second state, determines a first delay period according to a random process, identifies an apparent conclusion of the fault event, and in response to the apparent conclusion of the fault, waits for the first delay period before switching the component back to the ON state. The component consumes less power in the second state than in the ON state.

    Abstract: A sensor module for a compressor having an electric motor connected to a power supply is provided. The sensor module includes an input that receives current measurements generated by a current sensor based on a current of the power supply. The sensor module also includes a processor. The processor is connected to the input, determines a maximum continuous current for the electric motor, and selectively compares the current measurements with a value equal to the maximum continuous current multiplied by a predetermined value. The maximum continuous current is set based on at least one of a type of refrigerant used by the compressor and actual refrigeration system conditions.

    Abstract: A compressor diagnostic device is provided and includes at least one of a temperature sensor and a current sensor. The current sensor measures a first current flow through a motor of a refrigerant compressor. The temperature sensor is disposed within and sensing a temperature of a measurement region of an electrical conductor that is configured to close and open to allow and prevent current flow to the motor, respectively. The compressor diagnostic device also includes a controller in communication with the at least one of the current sensor and the temperature sensor. The controller is operable to control the electrical conductor based on a comparison of a second current flow through the motor and a maximum current.

    Abstract: A method of operating a refrigeration system that receives power from an electrical grid includes selectively operating at least one component of the refrigeration system in a first state. The method includes selectively detecting a fault event of the electrical grid in response to a concurrent (i) increase in amount of current drawn by the component and (ii) decrease in voltage of power received by the component. The method includes, in response to detecting the fault event, switching the component from the first state to a second state. The component consumes less power in the second state than in the first state. The method includes determining a first delay period. The method includes identifying a conclusion of the fault event. The method includes, in response to the conclusion of the fault event, waiting for the first delay period before switching the component back to the first state.

    Abstract: A compressor is provided and may include a shell, a compression mechanism, a motor, a data module, and a compressor controller. The data module may include a data module processor and a data module memory. The compressor controller may include a controller processor and a controller memory distinct from the data module processor and the data module memory. The data module may receive sensed data, may store the sensed data in the data module memory, may determine a first diagnosis of the compressor based on the sensed data, and may communicate the sensed data and the diagnosis to the compressor controller. The compressor controller may determine a second diagnosis of the compressor based on the sensed data and may verify the first diagnosis by comparing the first diagnosis to the second diagnosis.
