Siemens LGB22.230B27 Oil / Gas Burner controller
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.
