Siemens Burner Controls LMV6

Siemens
Siemens Burner Controls LMV6 Series is a microprocessor-based Burner Management System designed for medium- to large-capacity forced draft gas burners. It integrates burner sequencing, flame supervision, electronic fuel-air ratio control for up to three actuators, gas valve proving, and flue gas recirculation (FGR). With CAN bus communication and compatibility with the AZL66 operating unit, the LMV6 supports reliable burner operation, diagnostics, and combustion management in industrial boiler and heating applications.

Product Description

Siemens Burner Controls LMV6 Series

Siemens LMV6 Series is a microprocessor-based Burner Management System designed for controlling and monitoring medium- to large-capacity forced draft gas burners. It provides integrated burner sequencing, ignition control, flame supervision, and combustion management functions.

The LMV6 combines electronic fuel-air ratio control, gas valve proving, and flue gas recirculation (FGR) within a coordinated burner management platform. The system supports up to three actuators and provides CAN bus communication for compatible system components.

Key Features of Siemens LMV6

  • Integrated burner control and ignition sequencing
  • Electronic fuel-air ratio control
  • Supports up to three actuators
  • Integrated gas valve proving system
  • Flue gas recirculation (FGR) functionality
  • Flame supervision using an ionization probe or compatible UV flame detectors
  • CAN bus communication for compatible system components
  • Fault history and operating status diagnostics
  • Parameterizable program times and functions
  • Separate restart counter for each fuel

Flame Supervision

The LMV6 supports flame supervision using an ionization probe for continuous operation. For intermittent operation, compatible flame detectors include QRA2, QRA2M, QRA4, and QRA10 UV flame detectors, as well as ionization probes.

Control and Communication

The system communicates with compatible components through its integrated CAN bus interface. The AZL66 display and operating unit enables menu-driven parameterization, operating status monitoring, and fault diagnostics. Password-protected access levels help prevent unauthorized parameter changes.

Typical Applications

  • Medium- to large-capacity forced draft gas burners
  • Industrial boiler systems
  • Industrial heating equipment
  • Combustion systems requiring electronic fuel-air ratio control
  • Burner installations requiring advanced monitoring and diagnostics
Important Note: Installation, commissioning, and parameterization of the LMV6 must be performed by qualified personnel in accordance with Siemens technical documentation and applicable safety requirements.
