8.1.3 Faults During Operation
Faults occuring during operation may have 2 sources:
1. Main falme is not recognised sufficiently
• Check the flame scanner’s sight opening for soiling.
• Check whether the main flame burns stably. It is visible by the flame scanner in the whole
operating radius.
• Check whether there is enough of the mane flame in the visual window of the flame scan-
ner.
• Measure the flame radiation which is detected by the flame scanner, if necessary change
the adjustment, immersion depth in burner tip inclusively.
2. Radiated interference avoid a stable detection
• The red LED switches OFF and the green LED switches ON. Though the green LED does
not change its brightness in a 3-second intervals. A common-mode interference is pending
(the signal is pending on both evaluation channels simultaneously).Focus is on radiation
of the pilot transformer and its connected cables inclusively).
– Check if the shielding is connected correctly.
– Check the laying of the cables and if necessary disentangle/separate
