LME69.200C1BM Siemens Burner Control

Overview

The Siemens LME69.200C1BM is a microprocessor-based burner control unit designed for the startup and supervision of one- or two-stage gas burners in intermittent operation. As a high-performance component of the Siemens LME series, it ensures the safe operation of combustion systems by providing advanced flame supervision and automated control sequences. This model is a direct, updated replacement for the obsolete LME69.200A1BM, offering enhanced reliability for industrial and commercial heating applications, including specialized markets such as grain dryers.

Features

• Microprocessor-based technology for accurate digital signal handling and program sequences
• Multicolor LED for clear indication of operational status and fault messages
• Integrated undervoltage detection to prevent unsafe operation during power fluctuations
• Air pressure supervision with a functional check of the air pressure switch during startup and operation
• Electrical remote reset facility for streamlined maintenance and troubleshooting
• Controlled intermittent operation with a mandatory shutdown every 24 hours of continuous use
• Built-in limitation for the number of repetition attempts to enhance safety

Specifications

• Model: LME69.200C1BM
• Supply Voltage: AC 110 V (50/60 Hz)
• Control Type: Burner Control / Flame Safeguard
• Design Lifetime: 250,000 startup cycles (approx. 10 years under normal conditions)
• Weight: Approximately 0.15 lbs
• Approvals: CE approved, DIN EN 298 compliant
• Protection: IP40 (when built-in)

Applications

• Supervision of one- or two-stage gas burners or gas/oil burners of small to medium capacity
• Forced draft gas burners using ionization probes or QRA flame detectors (with AGQ3 ancillary units)
• Blue-burning flames using QRC blue-flame detectors
• Ideal for industrial and commercial heating systems, boilers, and grain drying equipment
• Replacement for legacy Siemens LGB and LMG burner control units using the same housing dimensions
