Fail – Safe System
The Fail-Safe System is a set of features that allow an application to continue running in the
event of certain types of "soft" failures. These "soft" failures include:
• Battery power loss
• Battery-Backed Register RAM or Application Flash corruption due to, for example, an
excessive EMI event.
Selecting “Fail-Safe System” menu will open the following menu screen:
Backup = Copies Battery Backed RAM contents on to the onboard flash memory of the
OCS.
Restore = Copies the backed up data from onboard flash to the battery backed RAM.
Clear Backup = The backup data will be erased from the onboard flash.
Exit = Goes back to previous menu.
