Use
LFS1 units are designed for the supervision of oil burners and gas burners in combination with control unit LEC1 or with programmable logic controllers. Typical fields of application range from industrial burners up to the highest security level SIL3 and in the field of ship burners.
Flame supervision:
- takes place with photocell detector RAR9 with approval for continuous operation, in the case of LFS1.1
- takes place with an ionization probe with approval for continuous operation or with UV flame detector QRA2 / QRA4 / QRA10 in intermittent operation, in the case of LFS1.2 Excluded are the types QRA2M and QRA10M.
The flamedetectors are used in conjunction with control unit LEC1 or with freely programmable controllers in the following applications:
-Dual supervision of burners / supervision of the main flame or of the ignition and main flame by 2 flame safeguards with the same or different flame detectors
- Multiflame supervision / plants with several burners whose flames must be supervised individually by one or several flame detectors, but whose startup and supervision is carried out centrally and simultaneously by only one
control unit
control unit
- The flame safeguards are also used as flame indication units in combustion plants with manual startup U
Features
- Flame signal display via multicolor LED signal lamp
- Flame signal display via 0...10 V output signal
- Can be parameterized via BCI communication interface
- Potential-free signal contacts with double insulation
- Undervoltage detection
