Siemens LMO64.301C2 control box

Siemens LMO64.301C2 burner control unit - oil burner control based on a microcontroller for starting, controlling and monitoring forced draught oil burners with intermittent operation. The LMO64.301C2 burner control is used for starting and monitoring 1- or 2-stage forced draught burners with intermittent operation. Yellow flame monitoring is performed by photoresistive sensors QRB, oxidative flame monitoring by blue flame sensors QRC. Undervoltage detection. Remote electrical restart capability. Shunt contact for oil preheater. Time monitoring for oil preheater. Precise and reproducible control sequence thanks to digital signal processing. Limitation of restart attempts. Multi-color indication of fault status and operational messages. The housing is made of impact-resistant, heat-resistant and flame-retardant plastic. The removable design snaps into the base. The Siemens LMO64.301C2 control housing contains the following elements: microcontroller for command sequence control and load control relays, electronic flame signal amplifier, reset button with built-in multi-color LED for operating status and fault indication, and a socket for connecting the OCI400 interface adapter or AGK20 reset button extension.
