Passwords - GE F650 User Manual

3.2 HUMAN-MACHINE INTERFACE (HMI)

3.2.6.10 Passwords

The F650 units incorporate independent passwords for protection and control, in order to prevent unauthorized keypad
and display access to the relay.
Settings Password:
This password restricts access to settings changes in the relay protection elements.
Commands Password:
This password restricts access to executing operation commands through the keypad and display.
If the Commands Password is activated, when the user tries to execute an operation, the relay requests this password.
When using single-line diagrams for graphical display models, all objects are not operational until the password is entered,
either by logging in to Login Pwd Commands, or by entering the password in the Commands menu.
Relay settings view, measures, and other monitored information are not password-protected, and can be accessed by all
users.
The password menu is located at the Password option in the relay text menu. This menu includes the following options:
"Login Pwd Settings"
"Logout Pwd Settings"
"Change Pwd Settings"
"Login Pwd Commands"
"Logout Pwd Commands"
"Change Pwd Commands"
"Forgot Password?"
Among the available options in this menu, there are three types of functionality:
Login:
Logout:
Change:
Forgot Password:
Passwords are restricted for Settings change and Commands execution. To password-protect the relay, it is first
necessary to set the desired password, using the corresponding Change Pwd... menu. The default password is 0000. This
password provides access to the whole relay functionality.
Once a new password has been set, the user must log in to access the protected functionality; otherwise, the relay
requests the password when trying to change settings or execute commands. Once the password is entered the relay is
unprotected (as if the user had logged in), and remains so for 15 minutes of inactivity or until the user logs out.
Password range
The valid range for F650 passwords is a number from 0000 to 9999.
The default password is 0000, which provides access to the whole relay functionality. This is the default option for enabling
relay use without using passwords.
Entering passwords (Login PWD)
This operation is the same for both the settings and commands passwords. The only difference is the access menu. For
entering the password, the user must access the Login menus inside the Password menu.
Login Pwd Settings or Login Pwd Commands:
The relay requests the password with the following message on the screen:
3-54
For entering the password, either for settings or commands, and enable access to settings
or commands. Once entering the password the relay is no longer password protected, and
access is enabled to settings modification or commands execution.
Once the necessary setting changes or operation commands have been executed, the
user can log out, so that the relay is password protected again.
Setting or modifying the desired password.
Retrieves the encrypted password, so that it can be recovered if the user loses or forgets it.
