Internal tests
During normal operation, the flame detector performs self-tests of its optics, electronics and software. These
include a periodic BIT (Built-In-Test) in which the sensors and window cleanliness are tested. Any detected
fault is indicated as shown in Table 4 (in section 5.1). D
uring “Dirty Window” fault the detection sensitivity is
