Supervision and indication of oil flames, for oil burners with/without fan.
Supervision of gas/oil flames, for gas burners with/without fan.
Intended for OEMs; advises against use for new designs.
Use with LEC1 for dual-supervision, forced draft, multiflame, and manual startup.
Compatibility with other burner controls and manual startup combustion plants.
Guidelines to prevent injury, property damage, and environmental harm.
Warnings on tampering, electrical shock, impact damage, and UV radiation.
Ensure drop out delay time of relay «d» does not exceed 50 ms.
Comply with regulations; mount on burner/panels; run ignition cables separately.
Ensure disturbance-free signal transmission; use separate cables and observe lengths.
Adherence to CE directives and standards for gas/oil burner controls.
Designed lifetime of 250,000 startup cycles or approx. 10 years.
Dispose of electronic components properly; unit has plug-in design with impact-proof housing.
LAE10: light simulation test; LFE10: UV tube voltage increase test.
Supervision using UV detectors (QRA/QRA10/QRA4) or ionization probe.
Overview of flame safeguards and ordering information for LAE10/LFE10.
Available flame detectors include UV types (QRA2, QRA10, QRA4) and silicon photocell (RAR9).
Details on low and high plug-in bases with 10-pole screw terminals and cable entries.
Specifications including mains voltage, frequency, power consumption, and contact rating.
Weight details for LAE10 and LFE10 with and without plug-in bases.
