2.2.3 Optical test
There are four LEDs located behind the enclosure window. They emit infrared
light that is reflected by both the internal and external surfaces of the enclosure
window. The reflections are continually monitored by the detector and if they are
disturbed the detector signals an optical fault.
The optics of the Dräger Flame 3000 can also be checked using the Dräger FS-
5000 Flame Simulator.
2.2.4 Explosive atmosphere protection
The Dräger Flame 3000 is certified for use in some potentially explosive
atmospheres. The explosion protection approval is valid for use of the device in
gas/vapour-air mixtures of combustible gases and vapours under atmospheric
conditions. The explosion protection is not valid for use in oxygen-enriched
atmospheres.
WARNING
Do not open the enclosure in the presence of an explosive atmosphere as it
could lead to an explosion.
Ensure that the flame path of the Dräger Flame 3000 is not damaged during
installation. A damaged flame path could lead to an explosion.
CAUTION
Only appropriately trained service personnel may open the enclosure. Incorrect
disassembly of the Dräger Flame 3000 may damage the equipment.
2.2.5 Status LED
The status of the flame detector is indicated by the color of a status LED located
below the lens.
