| 产品介绍 |
The LGB... burner controls are used for the startup and supervision of single- or 2-stage gas or gas / oil burners in intermittent operation. 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... (also refer to ?Replacement types under Ordering).
Automatic forced draft burners for gaseous fuels to EN 676
Gas burner controls to EN 298
Undervoltage detection
Air pressure supervision with functional check of the air pressure monitor during startup and operation
Electrical remote reset facility
LGB41... for use with atmospheric gas burners
