Abstract
A system for generating electrical signals which are intended to control a flow limiting device, in particular in a fuel control apparatus, has duplicate signal generating circuits which are responsive to operation of the fuel control apparatus and which generate nominally indentical output signals when an operating condition of the fuel control apparatus exceeds predetermined limits. Output signals from the duplicate circuits are supplied to the limiting device by way of respective control circuits each of which is enabled by the presence of a corresponding output signal from the other of the signal generating circuits. A device is provided for detecting a malfunction of one of the signal generating circuits and for permanently enabling the control circuit.
