Start restore manually
If the Auto restore option is not activated, the restore process can be started in BS350 based on the
backup data stored in the components of the tightening cell.
The restore process is carried out for all components without plausibility check. Only the state at the time
of the last backup can be restored.
Special case: Restore after replacement of the KE communication unit
When changing the KE in a multi-channel system, a new CF350 may also be installed with the new KE.
To prevent automatic restore of a backup not fitting the tightening cell, the contents of the backup are
checked for plausibility. The automatic restore is only executed if at least one component is recognized
by the KE.
This means, at least one component with the related serial number must exist in the tightening cell and
the administration structure of the automatic backup (CF350) on the KE.
7.4.4.3 Deleting of backup data on tightening cell components
No longer required backup data stored on the components of a tightening cell can be deleted by means
of Data Delete SE/CS or Data Delete KE.
7.4.4.4 Status of the automatic backup
In BS350, the status of the backup of every channel of a tightening cell can be checked. With menu item
System test Tightening cell info Auto backup/restore, the status of the backup is displayed.
If the ACTUAL state does not correspond to the TARGET state of the automatic backup, the
corresponding line will be marked in red in the Auto Backup/ Restore diagnosis and the tool tip TARGET
/ ACTUAL difference in the Auto Backup / Restore in the administration structure will be output.
There may be different causes:
• Firmware file *.bfw not available
• Firmware file *.bfw is not suitable for the current firmware
• Backup file *.chl or *.cel not available
• Backup file *.chl or *.cel is not suitable for the component and/or the channel slot
To remove the TARGET/ACTUAL difference in the Auto Backup/Restore in the administration structure,
an automatic backup needs to be carried out.
Auto restore should never by canceled. In case of cancelation, error 2935 “Restore was interrupted. Data
could be corrupt. Repeat restore.” will be entered.
By repeating the Auto restore (e.g. via BS350), the system can be brought back into the status of the
currently saved backups.
