LFE10和LAE10都為配合西門子專用火焰探測器使用的火焰檢測器。

LFE10可以與SIEMENS西門子公司的QRA...系列火焰探測器或者離子探針配合使用，把模擬量電流信號轉換為開關量信號，并輸出給燃燒器程控器。

LAE10可以與SIEMENS西門子公司的RAR...系列燃油火焰探測器配合使用，把模擬量電流信號轉換為開關量信號，并輸出給燃燒器程控器。

此兩款火焰檢測器必須每24小時停止工作一次。如需要24小時連續(xù)工作，請選用LFE50系列產品。

Flame safeguards for burners with intermittent operation. For safety reasons - self-test of flame supervision circuit, etc. - at least one controlled

Flame safeguards are used primarily in conjunction with the LEC1 burner control on the following applications:

• Dual-supervision of burners: Supervision of the main flame or of the pilot and main flame by two identical or different types of flame detectors

• Supervision of forced draught oil / gas burners: Supervision of the flame with different types of detectors, depending on the operating mode

• Multi-flame supervision: Plants with several burners whose flames must be supervised individually by one or several detectors, whose startup and supervision, however, should or must be carried out centrally and simultaneously by only one burner control

• The flame safeguards can also be used in connection with other types of burner controls provided the given combination and selected circuitry do not impair the burner controls safety functions

• The flame safeguards are also used as flame indication units in combustion plant with manual startup
