Abstract
The burner system (17) includes a burner (28), an air/fuel supply, and a burner control (12) that includes a pair of valve assemblies (13,14) with a flow control (18) and two valve actuators (10,11). A position encoder (108) is rigidly connected to the flow control member (18) and generates valve position signals. Control modules (112 are programmed to drive and store calibration parameters specific to the position encoder (108). During operation, the control modules command positioning of the flow control member (18) and compare the position signals to the stored positions to determine correct valve position.
