SIEMENS LGK16.622A17 110V SIEMENS LGK16.622A27 220V 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 good flame detector curr
