摘要： First through third relays (K1-K3) are connected in series, and a load (4) does not operate unless all are in the ON state. This enables the prevention of failures such as spilling of fuel due to a malfunction of the load, even when there is a fault in any of the first through third relays img id="iaf01" file="imgaf001.tif" wi="175" he="119" img-content="drawing" img-format="tif"/>

摘要： An RTC, having a crystal oscillator of different characteristics from those of a crystal oscillator, is provided, and the pulse period of the pulse signal from the RTC and the pulse signal based on the crystal oscillator are compared to detect a fault in the crystal oscillator. As a result, even if, for example, located in a high temperature environment, the degrees to the decrease in frequency will be different, thus making it possible to detect reliably a fault in the crystal oscillator.

摘要： Two controlling devices, namely a combustion controlling device controlling the combustion of a combustion furnace, and a safety controlling device checking the operation of the devices wherein the operations are controlled by the combustion controlling device. This enables safer control of combustion because if there is a fault in either the combustion controlling device or the safety controlling device, a process can be performed by the other device to stop the combustion. Additionally, because the controlling device for controlling the structural elements that control the combustion in the boiler system and the controlling device for operational checks of the outputs from those structural elements are separate, if there is a failure in any of the structural elements or controlling devices, that failure can be detected reliably, enabling safer control of the combustion.
