LMV36.300A2 Siemens Burner Control

Overview

The Siemens LMV36.300A2 is a microprocessor-based burner management system designed for the control and supervision of forced draft burners of medium to high capacity. This versatile unit integrates burner safeguard functions with electronic fuel-air ratio control, supporting both continuous and intermittent operations. Engineered for efficiency and safety, it simplifies gas train assemblies by providing integrated valve proving and flexible communication interfaces like Modbus, making it a central component for modern industrial and commercial combustion systems.

Features

• Integrated fuel-air ratio control for up to two SQM3 or SQN1 actuators
• Burner management system complete with integrated gas valve proving (leak testing)
• Supports both continuous and intermittent burner operation
• VSD (Variable Speed Drive) control for air fan optimization
• Modbus RTU (RS485) communication interface for integration into building management systems
• Advanced safety monitoring with all-polar input and output terminals
• Designed for approximately 250,000 startup cycles (roughly 10 years of service life)
• Compatible with a wide range of flame sensors, including ionization and UV detectors
