SECURITY
CyberSentry or basic security applies, depending on purchase. This section outlines password access. See the next sec-
tion and the Security chapter for information on setting up user accounts and CyberSentry security.
Two levels of password security are provided via the
ACCESS LEVEL
setting: command and setting. The factory service level
is not available and intended for factory use only.
The following operations are under command password supervision:
• Operating the breakers via faceplate keypad
• Changing the state of virtual inputs
• Clearing the event records
• Clearing the oscillography records
• Clearing fault reports
• Changing the date and time
• Clearing the breaker arcing current
• Clearing energy records
• Clearing the data logger
• Clearing the user-programmable pushbutton states
The following operations are under setting password supervision:
• Changing any setting
• Test mode operation
The command and setting passwords are defaulted to “0” when the relay is shipped from the factory. When a password is
set to “0”, the password security feature is disabled. As shown in the figures, the window indicates when the password is at
the default and when the password has been set.
