Use

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... (refer to Data

Sheet 7696), 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.
