Note
Replacement of the system CompactFlash card between different PPUs
Because of the system-related dependency between the CompactFlash card and SRAM for
the data storage in the SINUMERIK 828D, the system CompactFlash card should be
considered as a permanently installed EEPROM and should not be replaced!
If this has to be performed for imperative reasons, the replacement of the system
CompactFlash card is detected during startup because of the stored serial number.
The reaction of the control is the loading of saved data during startup (backup was performed
previously with "Save data" softkey). If no stored data is found, a startup is performed
automatically with the "NCK default data".
Empty RTC capacitor
If the RTC capacitor is discharged, the following message is issued during startup:
You can then reset the date and time:
The capacitor is then charged again when the control is switched on during startup.
