|
The LFE50... together with the QRA50M / QRA51M form a self-checking UV flame supervision system (DETACTOGYR®) designed for use with continuously operating oil or gas burners or burners operating without interruption for more than 24 hours.
LFE50... and the flame detectors QRA50... / QRA51.... It is designed for UV supervision and can therefore be used in connection with oil burners, gas burners and gas / oil burners. Automatic startup and control of these burners must be ensured with a control unit LEC1... (refer to Data Sheet 7761). The system is also suited for the supervision of manually operated burners.
Prerequisite for the use of the DETACTOGYR system is sufficiently high UV radiation at the flame detector’s mounting location.
For combustion plant where heat generation must also be ensured in the event the flame supervision system fails, active redundancy circuitry can be accomplished by using 2 DETACTOGYR systems. | |
