Siemens Burner Controllers LGB Series
Product Description
Siemens Burner Controllers LGB Series
Siemens Burner Controllers LGB Series are automatic gas burner control units designed for the startup, ignition control, and flame supervision of small to medium-capacity gas burners, typically up to 350 kW.
The LGB Series supports single-stage and two-stage gas burners operating in intermittent mode. Depending on the model, flame supervision is performed using an ionization probe, QRC1 blue-flame detector, or QRA UV flame detector with the AGQ1.xA27 auxiliary unit.
Key Features
- Automatic gas burner startup and ignition sequence control
- Supports single-stage and two-stage operation depending on the model
- Flame supervision using ionization, QRC1, or QRA detection systems
- Integrated undervoltage detection
- Air pressure supervision on applicable models
- Safety lockout in the event of burner malfunction
- Electrical remote reset capability
- Plug-in design for convenient installation and replacement
Available LGB Series Models
- LGB21: Designed for single-stage or two-stage forced-draft gas burners.
- LGB22: Designed for forced-draft gas burners with air damper actuator control.
- LGB32: Designed for forced-draft gas burners with QRC1 blue-flame supervision.
- LGB41: Designed for atmospheric gas burners, with or without a fan.
Applications
Siemens LGB Series burner controls are suitable for gas-fired heating and combustion systems, including industrial boilers, heating equipment, and gas burner installations. Model selection must be based on the burner configuration, ignition sequence, and required flame detection system.
Model Selection and Replacement
Siemens identifies the LGB Series as unsuitable for new designs and recommends considering the LME Series for new applications.
For replacement applications, verify the exact model number, supply voltage, safety timing, burner operating sequence, flame detector compatibility, and electrical connections before installation.
