Siemens LMV6 Series Burner Management Controls

Siemens LMV6 Series is a microprocessor-based burner management system for medium- to large-capacity industrial forced-draft gas burners. The LMV60.110A2 combines burner sequencing, flame supervision, electronic fuel-air ratio control for up to three actuators, and integrated gas valve proving. CAN bus connectivity enables integration with Siemens SQM4 actuators and the AZL66 operating unit for parameter configuration and fault diagnostics. Selected LMV62 models additionally support flue gas recirculation (FGR) and variable-speed fan control. Suitable for industrial boilers and process heating applications.

Product Description

Siemens Burner Controls LMV6 Series

Siemens LMV6 Series is a microprocessor-based burner management platform designed for controlling and supervising medium- to large-capacity industrial forced-draft gas burners. It provides coordinated burner sequencing, ignition control, flame supervision, and electronic combustion management.

The LMV60.110A2 integrates electronic fuel-air ratio control for up to three compatible SQM4 actuators, gas valve proving, and burner safety functions. Its CAN bus communication interface connects compatible components, including the Siemens AZL66 display and operating unit, enabling parameter configuration, operating status monitoring, and fault diagnostics.

Other models in the LMV6 family offer additional capabilities. Selected LMV62 models support flue gas recirculation (FGR) and Variable Speed Drive (VSD) fan control. These functions are not available on LMV60.110A2.

Key Features of Siemens LMV6

  • Microprocessor-based burner control with integrated ignition sequencing
  • Electronic fuel-air ratio control for coordinated combustion management
  • LMV60.110A2 supports up to three compatible SQM4 actuators
  • Integrated gas valve proving system
  • Flue Gas Recirculation (FGR) available on selected LMV62 models
  • Flame supervision using compatible ionization probes or UV flame detectors
  • CAN bus communication for AZL66 and compatible system components
  • Fault history, operating status monitoring, and diagnostic functions
  • Parameterizable burner program times and operating functions
  • Restart counter and configurable operating functions

Flame Supervision

The LMV6 supports flame supervision using compatible ionization probes for continuous operation. Depending on the detector and configuration, compatible UV flame detectors such as QRA2, QRA2M, QRA4, and QRA10 can be used for intermittent operation. Detector selection and any required flame signal amplifier must follow Siemens documentation.

Control and Communication

The integrated CAN bus connects compatible Siemens system components. The AZL66 display and operating unit provides menu-based parameter configuration, operating status information, and fault diagnostics. Password-protected access levels help prevent unauthorized changes to safety-related parameters.

Typical Applications

  • Medium- to large-capacity forced-draft gas burners
  • Industrial steam and hot water boilers
  • Industrial heating and thermal process equipment
  • Combustion systems requiring electronic fuel-air ratio control
  • Burner systems requiring detailed monitoring and fault diagnostics
