Abstract:
1. A combustion control device comprising: a power cutoff circuit electrically connected to a first output terminal line and a second output terminal line, either a first stop signal or a second stop signal controlling said power cutoff circuit to inhibit a supply of fuel to an element; a monitoring circuit configured to detect a first criterion of a system component and to detect a second criterion of the system component, a monitoring signal being output from said monitoring circuit; a sub controller configured to output said first stop signal onto said first output terminal line only when a first input signal indicates an existence of the first criterion, said first input signal being said monitoring signal that has been received by said sub controller; a main controller configured to output said second stop signal onto said second output terminal line when a second input signal indicates the existence of the second criterion, said second input signal being said monitoring signal that has been received by said main controller, wherein said main controller is configured to detect a difference between said second input signal and said first input signal.
