  • 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.

  • Publication number: 20190248625
    Abstract: A method for preventive maintenance of an elevator speed sensor system includes at least a first and a second sensor, which are independent of each other. The method includes: determining a reference distance for an elevator car travel between a first door zone and a second door zone, during the elevator car travel, defining continuously a first elevator car speed information from the first sensor and a second elevator car speed information from the second sensor, calculating a cumulative sensor system error by integrating the difference between the first elevator car speed information and the second elevator car speed information, and dividing the cumulative sensor system error with the reference distance to obtain a sensor system performance indicator.
