The Siemens LME7 Burner Controller for Gas Industrial Burners is an advanced microprocessor-based burner management system developed for the automatic startup, supervision, and shutdown of forced-draft gas burners. It is commonly used in medium to large industrial combustion systems, where precise burner control and high safety standards are required.

The controller manages the full burner sequence including pre-purge, ignition, flame monitoring, air pressure supervision, and safety lockout, ensuring safe and stable burner operation. It supports single-stage, multi-stage, and modulating burner configurations, making it suitable for a wide range of industrial heating applications.

Flame detection can be performed using ionization probes, UV flame detectors, or photocell sensors, ensuring reliable flame monitoring even in demanding combustion environments. The controller also integrates diagnostic indicators, lockout reset functions, and communication interfaces to simplify maintenance and system monitoring.

With its robust design, programmable functionality, and high operational reliability, the LME7 series is widely used by OEM burner manufacturers and industrial heating system integrators.

Technical Description

The Siemens LME7 Burner Controller is an electronic control unit designed for the automatic control and supervision of forced-draft gas burners operating in intermittent mode. The controller regulates the entire burner cycle including pre-purge timing, ignition control, flame detection, air pressure monitoring, and safety shutdown.

Flame supervision is performed using ionization probes, UV flame detectors (QRA series), or photocell detectors, ensuring rapid detection of flame failure and immediate burner shutdown. The controller uses microprocessor-based digital signal processing, enabling precise control sequences and enhanced operational diagnostics.

The LME7 series is widely integrated into industrial burner management systems, providing reliable burner automation and safe combustion control.
