Caution
The drive assembly may only be exchanged in consultation with the machine
manufacturer or by the machine manufacturer!
HDRs that you receive in exchange and new HDRs are already partitioned and formatted.
The HeROS operating mode and the NC software are installed. The HDRs are normally
equipped with the most recent NC software.
This NC software must be released by the machine manufacturer!
If the latest NC software has not been released by the machine manufacturer or if the NC
software version of your defective HDR should also run on the replacement HDR, it must be
loaded. For this purpose you also require support from the machine manufacturer.
Note: HDRs supporting dual-processor controls have loaded Windows.
Note
As of NC software version 34049x-04, the MC 420 or MC 422 B/C must feature a main
memory of minimum 256 MB.
With less working memory, the boot procedure is not completed!
If necessary, the main memory must be upgraded.
Note
If an external archive for the TNC data is already available, you need not to back up the TNC
partition. Thus you save time!
Contact the customer!
In this case, select the icon Scan system and machine files.
