  • Safety override circuit for pneumatic positioner and method of use thereof
    Patent number: 8196595
    Abstract: Systems and processes may provide improved performance for a pneumatic positioner during a safety override. In certain implementations, a system and process may include may include the ability to receive an input control signal, power control circuitry of the pneumatic positioner using the input control signal, and generate a control signal for a signal-to-pressure converter with the control circuitry based at least partially on the input control signal. The system and process may also include the ability to detect an unsafe operating condition for the pneumatic positioner based on an input signal and modify the control signal in response to detecting the unsafe operating condition, to cause the converter to transition to a safe state. The system and process may additionally include the ability to allow the control circuitry to continue being powered by the input control signal while the converter is in the safe state.
