Description
Siemens Burner Controls LGB…series for light oil/gas burners
the supervision, startup and control of 1- or 2-stage gas burners. As well as for gas burners / oil burners of small to medium capacity (typically up to 350 kW), with or without fan in intermittent operation.
Use
The LGB burner controls are used for the startup and supervision of 1- 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.xA27).
Using the appropriate adapter, the LGB can replace the predecessor types LFI7 and LFM1 in terms of function
- Applications in accordance with EN 676: Automatic forced draft burners for liquid fuels
- Type-tested and approved in accordance with EN 298:1994-02 or EN 298:1993
Feature
- Undervoltage detection
- Air pressure supervision with function check of the air pressure switch during startup and operation
- Electrical remote reset facility
- In the event that the mains voltage drops below about AC 165 V, an electronic circuit ensures that the gas burner control will prevent burner startup or – without releasing fuel – lockout will be initiated.
- LGB41 for use with atmospheric gas burners.
