Siemens Combustion LFL1.322-110V Control
The Siemens LFL1.322-110V is a heavy-duty, electro-mechanical gas burner control engineered for the supervised startup and monitoring of forced draft burners. Designed specifically for stationary air heaters and industrial atmospheric burners, this 110V AC unit facilitates secure sequencing for multistage or modulating burners in intermittent operation. It integrates a flame signal amplifier and sequence programmer into a single chassis, supporting flame supervision via QRA UV detectors or ionization probes.
With a fixed pre-purge time (t1) of 36 seconds and a 2-second safety time (TSA), the LFL1.322 ensures precise timing for combustion cycles. This Siemens flame safeguard features a built-in visual sequence indicator dial for real-time diagnostic monitoring and an integrated lockout reset button. It is a direct replacement for legacy combustion systems requiring high-capacity control and is compatible with dual-fuel applications. Technicians should note the requirement for a 6.3A slow internal fuse and the unit's IP40 protection rating for panel-mounted installations. This primary flame safeguard control is a standard for contractors maintaining medium to high capacity commercial heating plants.
Key Benefits for Technicians:- Universal Burner Compatibility: Supports gas, oil, or dual-fuel forced draft burners and stationary air heaters.
- Integrated Diagnostics: The front-facing sequence indicator dial identifies the exact point of lockout for faster troubleshooting.
- Checked Air Damper Control: Built-in logic verifies air damper positioning during start-up to ensure proper combustion airflow.
- Flame Supervision Versatility: Direct interface with Siemens QRA series UV sensors and ionization rods for reliable flame proving.
- Robust Construction: Electro-mechanical design provides high immunity to electromagnetic interference in industrial environments.
- Can this unit be used for continuous burner operation? No, the LFL1.322 is designed for intermittent operation, requiring at least one controlled shutdown every 24 hours. For continuous processes, the LGK series is the industry standard.
- What is the difference between the 110V and 230V versions? All timing specifications remain identical, but internal components are rated specifically for 100-110V AC @ 50/60Hz. Ensure your control transformer output matches this rating.
- Why is the burner locking out before ignition? Check terminal 11 connection to terminal 10; the air damper "z" switch must be in the fully closed position, or the sequence will not initiate.
