Siemens Combustion LFL1.333-110V Control
The Siemens Combustion LFL1.333-110V Control is a high-performance primary flame safeguard specifically engineered for the supervision and sequencing of gas, oil, or dual-fuel forced draft burners. Built for medium to high-capacity applications, this electro-mechanical controller manages multistage or modulating burners in intermittent operation, requiring a controlled shutdown every 24 hours to ensure safety integrity. The unit features a fixed 25-second prepurge period at 60Hz (nominally 31 seconds at 50Hz) to effectively clear the combustion chamber of residual gases before ignition. This 110V Siemens burner controller integrates the flame amplifier and sequencer into a single chassis, supporting flame supervision via UV detectors like the QRA series or ionization probes. Technicians value the LFL series for its visual sequence indicator and robust pre-ignition interlock, which provides reliable HVAC burner sequencing in demanding commercial environments.
Key Benefits- Universal Compatibility: Supports gas, oil, and dual-fuel burners for maximum field flexibility.
- Enhanced Safety: Features built-in air pressure supervision and a proven high-fire purge interlock.
- Visual Diagnostics: An integrated indicator dial allows for immediate identification of the startup sequence phase or lockout cause.
- Flexible Flame Detection: Accommodates both ionization probes and UV flame sensors for diverse installation requirements.
- Durable Construction: Designed to withstand 250,000 startup cycles, ensuring long-term reliability in industrial heating plants.
What is the difference between the 01 and 02 series?
The primary difference lies in the safety timing for the pilot burner; 02 series units typically feature specific timings tailored for burners utilizing pilot gas valves.
Can this unit be used with 50Hz and 60Hz power?
Yes, but note that switching times are approximately 17% shorter when operating on a 60Hz mains frequency compared to 50Hz.
How do I reset the controller after a lockout?
The lockout reset button is integrated into the front viewing window. It must be pressed manually and should not be held for more than 10 seconds to avoid damaging the internal electronics.
