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.
