LME39.100C1 Siemens Burner Control

Overview

The Siemens LME39.100C1 is a high-performance, microprocessor-based gas burner control designed for the startup and supervision of 1- or 2-stage gas or gas/oil burners. It is primarily utilized in small to medium-capacity industrial and commercial burner systems. Engineered for intermittent operation, the control ensures safe burner sequences by managing the fan, ignition, and fuel valves. It features a digital signal handling system that provides accurate program sequences and is compatible with the Siemens BCI for parameterization and diagnostics.

Features

• Microprocessor-controlled for precise and repeatable program timing
• Integrated undervoltage detection for safe shutdown during power fluctuations
• Air pressure supervision with functional checks during startup and operation
• Multicolor LED indication for visual status messages and fault diagnostics
• Electrical remote reset facility for easy system recovery
• Controlled intermittent operation with a mandatory shutdown after 24 hours of continuous use
• BCI communication interface for parameterization via PC or specialized service tools
• Robust design with a lifetime rating of approximately 250,000 startup cycles
