Flame controllers Siemens LGB41 ... for monitoring of atmospheric burners. Depending on the type of burner control used, the flame is supervised either by an ionization probe, a blue-flame detector QRC1... for forced draft gas / oil burners, or a UV detector QRA... (with auxiliary unit AGQ1...A27). In connection with the respective adapters, the LGB... burner controls replace their predecessor types LFI7... and LFM1... (see pdf.)

Specifiations:

- Complete reference: LGB41.258A27

- Automatic forced draft burners for gaseous fuels to EN 676

- Gas burner controls to EN 298 and burner controls for oil burners to EN 230: 1991-05

- Undervoltage detection

- Air pressure supervision with function check of the air pressure switch during startup and operation

- Electrical remote reset facility

- The housing is made of impact-proof, heat-resistant and flame-retarding plastic. It is of plug-in design and engages audibly in the base.
