Siemens LME73.000A2 Control Box
240v
The LME7 is a microprocessor-based burner control with matching system components for the control and supervision of forced draft burners of medium to high capacity. LME7 are used for the startup and supervision of 1- or 2-stage gas forced draft burners in intermittent operation. The flame supervision supervised with ionization probe optional with UV flame detector QRA2, QRA4.U or QRA10.

LME are used for the startup and supervision of stage or modulating oil / gas burners in intermittent operation. Flame supervision is ensured with an ionization probe or a QRA flame detector with / without AGQ3 ancillary unit, in the case of yellow-burning flames, with a QRB photo resistive flame detector.
