6.4.4.2 Hand optimization of the automatically determined trigger thresholds (levels)
WARNING!
Checking the switch-off parameters
There is a risk of death and serious injury.

The preset switch-off parameters are to be verified through switch-off tests, (see Section
6.4.5 Switch-off Test ).
The change of the trigger threshold, the gain of the weighting (UV/IR) and/or the frequency
setting affects the switch-off parameters and therefore requires renewed switch-off test.
The manual optimisation of the trigger threshold is based on the last point of the data trans-
mitted by "Automatic Optimisation" through the User Interface or F300K-Remote-Software.
If the automatic optimisation is finished, a symbol of manual optimisation would appear in the
higher level menu screen 300
.
In manual optimisation menu, a manual optimisation can be performed before or after saving
the evaluation results from the "Automatic Optimisation".
Screens for the display of evaluation results from the "Automatic Optimisation" pop up, and
they can be edited through DOWN or UP buttons.
Other procedures such as "Browse" and "Save"comply with automatic optimisation
NOTICE
The positions of the displayed trigger threshold corresponds to activation of menus which are
currently active in F300K available and could deviate from evaluation results. The displayed
limits corresponds to the evaluation results.

1 Parameter trigger threshold for flame
OFF
2 Process reliability, is the max. fault or
useful signal distance between flames
OFF and ON.
Shut-down parameter:- trigger threshold
power down
Fig. 6-23 With DOWN the trigger threshold would
be reduced
With DOWN, the trigger threshold would be
reduced and process reliability would be
reduced.
The deviation from automatic determined
process reliability would be displayed in %.
In case of failure to achieve pre-determined
limits of the process reliability, an error mes-
sage would be displayed.
