Siemens LGB21.350 A27 230v Burner Control Box Siemens LGB21.350 A27 230v Burner Control Box

Siemens LGB21.350 A27 Burner Control Box 230V

Overview

The LBG21.350 control box features undervoltage detection and air pressure supervision with a functional check of the air pressure switch during startup and 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).

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.
