1.5.4 RELAY ACTIVATION
The relay is in the default “Not Programmed” state when it leaves the factory. When powered up successfully, the Trouble
LED is on and the In Service LED off. The relay in the “Not Programmed” state blocks signaling of any output relay. These
conditions remain until the relay is explicitly put in the “Programmed” state.

RELAY SETTINGS
1.
To put the relay in the “Programmed” state, press either of the VALUE keys once and then press ENTER. The face-
plate Trouble LED turns off and the In Service LED turns on.
The settings for the relay can be programmed manually (see
Chapter 5
) via the faceplate keypad or remotely via the
EnerVista UR Setup software (see the EnerVista UR Setup help file).
1.5.5 RELAY PASSWORDS
a) PASSWORD SECURITY
It is recommended that passwords be set for each security level and assigned to specific personnel. There are two user
security access levels, COMMAND and SETTING.
1. COMMAND
The COMMAND access level restricts the user from making any settings changes, but allows the user to perform the fol-
lowing operations:
•
Operate breakers via faceplate keypad
•
Change state of virtual inputs
•
Clear event records
•
Clear oscillography records
•
Operate user-programmable pushbuttons
2. SETTING
The SETTING access level allows the user to make any changes to any of the setting values.
See the
Changing Settings
section in Chapter 4 for complete instructions on setting security-level passwords.
b) CYBERSENTRY
When the CyberSentry option is purchased, advanced security services are available, using either device authentication or
server authentication using RADIUS. When this option is purchased, the basic password security is disabled automatically.
For more information, see the CyberSentry content in the
Security
section of the next chapter.
1.5.6 FLEXLOGIC CUSTOMIZATION
FlexLogic equation editing is required for setting user-defined logic for customizing the relay operations. See the
FlexLogic
section in Chapter 5.
