Fig. 52 — Archive Screen
Select the Archive Now checkbox to archive the program. A blue
check mark appears in the box to indicate the process is running.
The archiving process should take less than 30 seconds to com-
plete. The blue check mark then disappears. Also, the red Archive
Valid LED bar (located on the top right corner of the controller)
will turn off, then light up when the archive process is complete.
RESTORING FROM ARCHIVE
The controller checks the memory configuration of the program
during power up. If the program is identified as corrupt, the con-
troller restores it from the last archive. The LS-1628 requires a
backup of the current setup when changes are made. This is done
through the Equipment Touch 2.
The factory or field archives can also be manually restored in the
field.
Creating a Field Archive
To create a field archive (Factory Download File), follow these
steps:
It is recommended doing this prior to any Restore and after any
Change to controller settings.

Setup button. (Factory password will be required.)
2.
Press the Misc Setup button on upper left of layout.
3.
Press the Archive button.
4.
There will be two check boxes on the Archive screen:
a. Backup Memory
b. Restore Memory
5.
Select the check box on the Backup Memory. Once checked,
the backup is automatic and will take about 30 seconds. You
will see a date stamp below the check box once complete.
6.
You have successfully created a Backup Archive.
