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.

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.
