3.2.6.10 PASSWORDS
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 allows restricting access to settings changes in the relay protection elements.
Commands Password:
This password is required for executing operation commands through the keypad and display.
If the Commands Password is activated, when the user tries to execute an operation, the relay will request this password,
and in case of using the single-line diagram for graphical display models, all objects will not be operational until this
password is entered, either logging in
Login Pwd Commands , or entering the password in the Commands menu.
Relay settings view, measures, and other monitored information are not password-protected, and they can be accessed by
all users.
Access to 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 : 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.
Logout : Once the necessary setting changes or operation commands have been executed, the
user can log out, so that the relay is password protected again.
Change : This menu allows setting or modifying the desired password.
Forgot Password : This menu provides the encrypted password, so that it can be recovered if the user loses or
forgets it.
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 will
request 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 the user must log out to protect again the relay.
a) 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.
