Notice
Saving of the user data in the SRAM of the MCI board in case of power failure
is only guaranteed if the PCU is operated within its defined specifications.
References /BH/ Operator Components Manual
Section: Component PCU 50
If the SINUMERIK 840Di has been operated outside its defined specifications, it
is under certain circumstances possible that the user data could not be saved in
the SRAM. Therefore, proceed as described in Subsection 6.3.4, page 6-183
case 2.
6.3.9 Ramp-up with shutdown signal (SW 2.3 and higher)
If the SINUMERIK 840Di is operated with a UPS system, the shutdown system
must be configured appropriately. See Subsection 10.10.2, page 10-399. When
the shutdown signal is present, the NC and PLC are terminated first and Win-
dows NT then shut down correctly.
If ramp-up takes place while the shutdown signal is present, Windows NT is
shutdown again straight away.
As of 2nd ramp-up with shutdown signal present produces the following system
behavior:
– Windows NT is not shut down correctly again
– NC and PLC are not started
– The following message box appears:
SINUMERIK 840Di NCK/PLC
Alarm: NCK started while Power Failure, shutdown with OK
OK
The circuit on the MCI board extension module and the configuration of
the shutdown signal (see Subsection 10.10.2, Page 10-399) can be
checked and modified if necessary.
If the shutdown signal is no longer present after acknowledging the mes-
sage box, the NC and PLC are started. Otherwise, Windows NT is shut
down correctly.
