DCS 500 12-Pulse Planning and Start-Up 6 - 1
You start up the 12-pulse configuration after mechanical and elec-
trical installation of the system has been fully completed. You will
find it best to proceed in three steps. First, start up each 6-pulse
unit separately. In the as-delivered condition, the parameters are
set for
single mode . The cross-connections between Plug Connec-
tors X18: and Terminals X3: and X4: of the two power converters
are not operative in the single-mode setting. For instructions on
start-up, please consult the
Installation and Start-up Manual
(DCS 500). It is best to disconnect the non-active unit from the
mains, or at least to disable it by suppressing the firing pulses. The
interphase reactor can remain connected throughout the entire
start-up procedure.
Master Starting up the master power converter:
- Isolate the slave, or suppress pulses.
- Start up the master power converter as a 6-pulse standard
power converter, in speed or current-controlled mode, depend-
ing on the utilization involved.
For the procedure involved, please consult the relevant standard
equipment documentation
Installation and Start-up Manual, Chapter
7
Slave Starting up the slave power converter:
- Isolate the Master or suppress pulses.
- Start up the slave power converter in current-controlled mode
as a 6-pulse standard power converter.
For the procedure involved, please consult the relevant standard
equipment documentation
