FEATURES
The components are contained in a cast aluminum NEMA 4X/IP66 housing sealed with an oil-resis-
tant gasket. The quartz lens is a planoconvex design, resulting in increased sensitivity. Also included
in the scanner is an electromagnetic shutter that permits a self-checking circuit to verify that the
scanner and signal circuits are producing valid flame presence or absence information. During the
shutter closed period, the detector’s optical path is blocked from flame radiation, allowing the inter-
nal microprocessor to verify the proper operation of the ultraviolet tube. While the shutter is open,
flame presence or absence is detected. The self-check shutter operation and fault diagnostics are fully
described later in this bulletin.
