Table 8.14 identifies all of the applications available in the Access Level

folder.

Note that when a folder requires the 2AC access level and the relay is at ACC,

the relay automatically pops up the authentication screen requiring you to

enter the password before performing a control operation, editing setting, etc.

Settings

Tapping this folder navigates you to the Settings screen where you can access

settings applications (Global, Touchscreen) or settings folders (Port, Group,

Date and Time) through which you can set or show settings.
