That supervision circuit initiates the required safety actions not only in the case of premature or missing flame signals, but also in the event of any kind of fault on the flame detector, the detector cables or the flame signal amplifier that could simulate a flame signal during burner operation.
The burner controls are therefore suited for use in all types of oil-fired combustion plants where self-checking flame supervision systems are either mandatory or recommendable:
