Abstract: A burner control system in which signals indicating the condition at various locations within the system are applied to a control circuit in the form of pulse trains, causing a continuous alternation of state of solid state switching elements therein. The system actuates a switch to open a fuel valve only when the level of the control circuit output signal is alternating, indicating that the said switching elements are operative. A comparison circuit compares the control circuit output signal with a signal denoting the condition of the fuel valve, to ensure proper operation of the fuel valve switch.

Abstract: A burner control system includes a plurality of field indicators indicative of the status of components of the burner system, control logic responsive to the field indicators for control burner control signals, logic bypass c0ntrol and circuitry responsive to the logic bypass control for establishing the status of the control logic as a function of the field indicators so that the control logic is maintained in synchronism with the field indicators.

Abstract: A burner control system has a field device and control logic for providing a control signal to change the state of the field device. A comparator that compares signals from field and the control logic comprises translation circuitry that is arranged to produce an output pulse train signal in response to a corresponding input pulse train signal, and power supply circuitry that has two logic inputs. The power supply circuitry supplies power to the translation circuitry only in response to a proper comparison between a field signal applied to one logic input and the control signal applied to the other logic input.

Abstract: Scanning apparatus includes a linear array of sensors so that there is effectively a series of independent sensor elements disposed in aligned relation generally perpendicular to a scanning axis. Each sensor is arranged to provide a data output in response to a sensed code mark and an output channel is coupled to each sensor. Logic responsive to detection of a first code mark by a sensor of the array enables at least one code sensitive group of output channels and disables other output channels so that only a limited group of channels are rendered responsive to subsequently detected code marks.
