  • Patent number: 4898263
    Abstract: An elevator self-diagnostic system monitors the operative status of various elevator components and upon sensing an error initiates action to bring the elevator car to a safe operating state. The system then logs the error. The diagnostic system then analyzes the error and the conditions prevailing at the time the error occurred and, if necessary, a corrective action is then taken to resolve the error. This allows the elevator system to be brought back into service more quickly than would otherwise be possible. Specifically, a number of tests are serially performed on various elevator components, such as the motor drive, the position sensors, etc. When an error, or fault, arises in a system component, a selt-diagnostic system logs a preselected error level which has been assigned to the particular fault. A preselected action is then taken according to the particular error.
