摘要：A burner system (17) includes a burner (28), an air/fuel supply system (21) and a burner control system (12). Burner control system (12) includes a pair of valve assemblies (13, 14) including flow control member (18) and a pair of valve actuator assemblies (10, 11). Position encoder (108) is rigidly connected to flow control member (18) and generates valve position signals. Control modules (112) are programmed to derive and store calibration parameters specific to position encoder (108). During operation control modules (112) command positioning of flow control member (18) and in response to position signals from encoder (108) compares the position signals to stored calibration parameters to determine correct valve position.
