LME71.111A1PKG-PRG10 Siemens Flame Safeguard

Overview

The Siemens LME71.111A1PKG-PRG10 is a preprogrammed flame safeguard control package designed for the supervision and management of 1-stage, direct or pilot ignited forced draft gas burners. This assembly functions as a burner control unit, ensuring safety by monitoring the flame via a UV scanner or flame rod and managing the energization of safety shutoff valves. The “-PRG10” designation indicates that the unit comes pre-configured with specific safety parameters, reducing the need for field programming while providing reliable protection against unsafe combustion conditions.
