Burner controls type LOK16... feature a self-checking flame supervision circuit. 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:
Burners that operate continuously
Burners in intermittent operation that, in the case of great heat demand, may operate continuously for more than 14 hours, e.g. in plants using boiler sequencing
Burners that need to comply with the German TRD 411 and TRD 412 regulations for steam boilers
Burners in plants where, for specific safety requirements, supervision of the burner by a self-checking flame supervision system seems advisable
