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. |
