Flame safeguards fr burners with intermittent peratin. Fr safety reasns - self-test f flame supervisin circuit, etc. - at least ne cntrlled shutdwn is required every 24 hurs. The LFE10 is suited fr the supervisin f gas flames and luminus r blue-burning il flames in cnnectin with UV detectrs QRA... r a flame rectificatin prbe.

Flame safeguards are used primarily in cnjunctin with the LEC1 burner cntrl n the fllwing applicatins:

• Dual-supervisin f burners: Supervisin f the main flame r f the pilt and main flame by tw identical r different types f flame detectrs

• Supervisin f frced draught il / gas burners: Supervisin f the flame with different types f detectrs, depending n the perating mde

• Multi-flame supervisin: Plants with several burners whse flames must be supervised individually by ne r several detectrs, whse startup and supervisin, hwever, shuld r must be carried ut centrally and simultaneusly by nly ne burner cntrl

• The flame safeguards can als be used in cnnectin with ther types f burner cntrls prvided the given cmbinatin and selected circuitry d nt impair the burner cntrl&rsqu;s safety functins

• The flame safeguards are als used as flame indicatin units in cmbustin plant with manual startup
