Fail-Safe System
The Fail-Safe System Sub-Menu 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.
The fail-safe system can be accessed by going to the system menu of the controller. The menu “Fail-
Safe System” has been added at the end of the main system menu for this.
Refer Chapter 14 for detailed explanation of Fail-Safe system.

This feature can be used for:
• Replacing an OCS by another unit of the same model.
• Duplicating or “clone” units without a PC.
