Technical Description: LFL1.322
The Siemens LFL1.322 is a robust **Gas Burner Control** designed for medium to high capacity forced draft burners. It handles expanding flame and interrupted pilot burners, ensuring safe startup and shutdown sequences for industrial boilers.
Key Features
- Voltage: 220-240 V AC.
- Pre-purge time: 31.5 seconds.
- Safety time: 2 seconds.
- Construction: Plug-in unit with exchangeable fuse.
Reliability
The LFL series is legendary for its durability. Unlike modern digital units, the **LFL1.322** uses a cam-switch mechanism driven by a synchronous motor, providing visual feedback of the program sequence via the viewing window. It is immune to voltage fluctuations and electrical noise.
Replacement
Often found in Landis & Gyr systems. This unit is critical for the operation of dual-fuel burners. We verify every unit before shipping to ensure the cam mechanism rotates smoothly.
