The LFE1... is designed for the fully automatic control and supervision of single-stage, multi-stage or modulating gas or dual-fuel burners. It is suited for use with expanding flame and interrupted pilot type gas burners.
Flame supervision is ensured by means of an ionization probe or a UV flame detector. Ignition spark proving with a UV flame detector is also possible.
When used in connection with a gas valve proving system LDU11... , the control sequence of the LFE1… can be extended to include automatic gas valve proving.
All types of LFE1... burner controls comply with the relevant European standards for gas and oil burners of any capacity.
The LFE1... can control the following burner plant components: fan motor, flue gas fan, air damper, ignition transformer, 1 to 3 fuel valves, load controller and an external lockout warning device.
