Adjustment
In certain cases, it may be necessary to change the
parameters set at the factory. Using the separate
software package BCSoft and a PC opto-adapter, it
is possible to modify parameters on the BCU, such
as the pre-purge time or the behaviour in the event
of a flame failure.
▷
The software package and the opto-adapter
are available as accessories – see page 27
(Accessories).
▷
Changed parameters are saved on the integrated
parameter chip card.
▷
The factory settings are secured with a program-
mable password.
▷
If the password has been changed, the end cus-
tomer can look up the changed password in the
plant documentation or ask the system supplier.
