Siemens LGA 52.150 B27 (LGA52.150B27) combustion controller

Gas burner controls for monitoring single- or two-stage low- and medium-power gas burners with intermittent operation. LME…

LME burner controls are used to start and monitor single- or two-stage gas burners with intermittent operation. Flame monitoring is performed using an ionization electrode or a QRA flame sensor with an AGQ3 auxiliary unit, or using QRC blue flame sensors.
The overall dimensions of the LME… housing are the same as those of the LGB… and LMG… combustion controllers (see “Overview of modifications”).
– Burner controls comply with EN 298
– Gas burners with fan comply with EN 676
– Low voltage detection
– Monitoring of air pressure by means of functional testing of the air pressure switch during start-up and operation
– Possibility of remote electric reset
– Multi-color indication of fault status and operational messages
– Limit the number of repetitions
– Precise control sequence thanks to digital signal processing
– Controlled intermittent operation after 24 hours of continuous operation
