7.0.4 Sensitivity – Switch/ sections 9.1 + 9.2, items 4 and 5
Depending on the solution type (F 200 K1 or F 200 K2), there are 1 or 2 sensitivity se-
lector switches. The sensitivity selector switches can be set in 6 steps. The switches
serve to adapt the device to the existing flame intensity. (refer to 7.1.3)
7.0.5 Frequency – Switch / section 9.2, item 6
The frequency switches are only included in the F 200 K2 solution.
They are used to set the lower frequency limits of the digital filters. This allows to im-
prove the selectivity in flame detection. In the F 200 K1 solution, only the lower fre-
quency limit of 10 Hz is factory-set principally. (refer to 7.1.3)
7.0.6 Service – Switch Serv. / section 9.1 + 9.2, item 6
The Serv. service switch serves to suppress the indication during start-up and star-
ting time of the flame detector. In the state as delivered, the
Serv. is in the ON posi-
tion. This function does not display any short flame signals of other radiation sources
(e.g. adjacent burners or background fire), which are not to result in a switch-on of the
flame detector.
For commissioning it is recommendable to set the
Serv. switch to OFF. Short
flame signal of other sources are thus indicated even during the start-up phase. This
information is important for a probably required change of the start-up suppression
setting (refer to 7.1.3).
7.0.7 Adjust – Switch / section 9.1 + 9.2, item 6
The Adjust switch serves to feed in the unevaluated flame intensity (direct signal at
the probe element) on the intensity display of the compact flame detector. The activa-
tion of the Adjust switch (ON position) suppresses the function of the
Serv. switch
(refer to 7.1.3).
7.0.8 Start-up suppression - Potentiometer / sections 9.1 + 9.2, item 9
The potentiometer serves to vary the setting of the start-up (switch-on) behaviour of
the flame detector. This setting has an influence on the switch-on behaviour of the
flame detector with regard to the flame to be monitored. (refer to 7.1.3)
7.0.9 Measuring p>YAX Coints / section 9.1 + 9.2, items 7 and 8
These measuring points serve to directly measure the flame signals at the probe ele-
ment and can be used to determine the optimal alignment, apart from intensity indica-
tion. (refer to 7.1.3).
