SIEMENS LGK16.322A17 110V SIEMENS LGK16.322A27 220V ORIGINAL BURNER CONTROL Burner controls ? For gas, oil or dual-fuel forced draft burners of medium to high capacity ? For multistage or modulating burners in continuous operation ? With air pressure supervision for checked air damper control. ? Flame supervision – LOK16: With silicon detector RAR – LGK16: With flame detector QRA53/QRA55/ionization probe ? Burner control for oil burners or gas burners in accordance with EN 298:2012 ? Suitable for use with air heaters (WLE) ? With self-checking flame signal amplifier The LOK16…/LGK16… and this Data Sheet are intended for use by OEMs which integrate the burner controls in their products Use Burner controls type LOK16…/LGK16… feature a self-checking flame supervision circuit. The flame supervision circuit initiates the safety actions in the case of… : • … premature or missing flame signal • … 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- or gas-fired combustion plant where self-checking flame supervision systems are either mandatory or recommended. For example: – 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 plant using boiler sequencing – Burners that need to comply with the German TRD 411 and TRD 412 regulations for steam boilers – Burners in plant where, for specific safety requirements, supervision of the burner by a self-checking flame supervision system seems advisable – The control sequence and connection circuitry of the LOK16…/LGK16… burner controls are identical to those of the LAL2… and LFL1… respectively (with the exception of the LFL1.148), so that existing combustion plant can also be equipped with self-checking burner controls, ? provided very
