Information About LFL1.635
The LFL1.635 belongs to the Siemens LFL1 series of burner control and flame safeguard units. It is suitable for multistage or modulating burners with checked air damper control and intermittent operation. Flame supervision can be provided using compatible QRA UV flame detectors or an ionization probe, while compatible SQN-series actuators can be used for air damper and burner control. The controller is designed for plug-in installation with compatible AGM410490550 or AGM14.1 bases and has an IP40 degree of protection.
Key Features:
- LFL1 Series: Part of Siemens' LFL1 family of burner sequence controllers.
- Gas, Oil, and Dual-Fuel Compatibility: Designed for medium- to high-capacity burners using gaseous, liquid, or dual fuels.
- 220–240 VAC Supply: Operates from a 220–240 VAC AC power supply at 50–60 Hz.
- 60-Second Prepurge: Provides a fixed 60-second purge period within the burner sequence.
- Flame Supervision: Supports flame monitoring with QRA UV detectors or an ionization probe.
- Burner Sequencing: Controls and supervises the operating sequence of compatible burner systems.
- Actuator Compatibility: Supports compatible Siemens SQN-series burner and air-damper actuators.
- IP40 Protection: Provides a defined level of protection for installation in suitable control environments.
The LFL1.635 delivers the burner sequencing and flame-safety control required for medium- and high-capacity industrial burner systems.
