6 .16 Changing parameters
In certain cases, it may be necessary to change the de-
fault settings. Using a separate software package and
a PC opto-adapter, it is possible to modify certain pa-
rameters on the BCU, such as the switch-off threshold
of the flame amplifier or the behaviour in the event of a
flame failure.
The software package with PC opto-adapter, as well as
"Changed parameters" stickers, are available as acces-
sories, see page 27 (Accessories).
The unit parameters set at the factory are specified in
the enclosed delivery note.
Document changed parameters in BCSoft using the
protocol function and enclose the protocol with the
plant documentation.
If a replacement is ordered for a BCU with changed pa-
rameters, refer to the protocol for details.
