Use:
LME are used for the startup and supervision of 1- or 2-stage gas burners or gas burners in intermittent operation. Flame supervision takes place via an ionization probe or a QRA2 / QRA2(1) / QRA2(2) / QRA2.9 / QRA4.U / QRA10.C UV flame detector with AGQ3.xA27 ancillary unit for forced draft gas burners, or, in the case of blue-burning flames, with a QRC1 blue-flame detector. In terms of housing dimensions, the LME are identical with the burner control LGB and LMG burner controls (refer to Type summary).
