  • Patent number: 10906773
    Abstract: Controlling an apparatus may include detecting a fault in the apparatus, such that a controller of the apparatus exits a normal operation state for controlling the apparatus and enters a faulted state based on the detected fault, operation of the apparatus is stopped based on the controller entering the faulted state, and the detected fault is recorded in a fault memory or a fault recorder of the controller. The controlling may include receiving a remote fault clearing command subsequent to detecting the fault, and clearing the detected fault in response to the remote fault clearing command, such that the controller exits the faulted state and enters the normal operation state, and operation of the apparatus is enabled based on the controller entering the normal operation state. Clearing the detected fault may include deleting the detected fault from the fault memory or fault recorder.
