Siemens LMO44.255 B2 Burner Control Box 230V

Overview

The LMO44.255 is a microcontroller based oil burner control box for the startup, supervision and control of forced draft oil burners in intermittent operation. Maximum oil throughput up to 30 kg/h.

The LMO44 control box features: Bridging contact for oil preheater, Monitoring of time for preheater, accurate and reproducible control sequence thanks to digital signal handling, the LMO limits the number of repetitions and has a multicolour indication of the fault status and operational staus messages.

In the event that the mains voltage drops below about AC 165 V, an electronic circuit ensures that the gas burner control will prevent burner startup or – without releasing fuel – lockout will be initiated.


LMO44.255 B2 Burner Control Box Applications


The LM44.255 contro box is designed for the startup and supervision of 2 stage forced draft oil burners in intermittent operation. Yellow-burning flames are supervised with photo resistive detectors QRB..., blue-burning flames with blue-flame detectors QRC... In terms of housing dimensions, electrical connections and flame detectors, the LMO44.255 is identical to the LOA oil burner controls..

Burner controls have a designed lifetime of 250,000 burner startup cycles which, under normal operating conditions in heating mode, correspond to approx. 10 years of usage
