Appendix B Proposed Initial Setting

Notes on the Proposed Initial Settings
Important values for flame detection that must be set before initial start-up are shown in
bold.
Other values that can be changed, but are not critical for flame detection are shown in
plain text.
Using Flame Explorer tool, the user can load from a file the predefined and default
values for a wide range of standard applications. Refer to SF910i Flame Explorer
User Manual (8VZZ005308) for details, and for a list of the pre-defined configurations
that are available.
For safety reasons, the user is requested to prove the Flame Failure Response
Time (FFRT) of the SF910i under any burner load/fuel conditions and under any
selected file of parameters. For EN298 application, the user need to set the DELAY
DROPOUT parameter to <= 0.9s to fulfill the requirement of EN 298 that the FFRT
shall not exceed one second. If there are further adjustments of the flame detector
(DELAY DROPOUT), do not cause the time to rise above one second.
