b) ENTERING THE PASSWORD (LOGIN PWD)
This operation is the same for both the settings and commands passwords. The only difference will be 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:
Setting passwd.
Login: < 1000 >
For entering the desired password, the user must rotate the shuttle key to the left (decrease) or to the right (increase), and
establish the desired number. Once entered, the selected password between brackets has been entered, the relay will
show the message
“Processing passwd. Wait...”
. If the password is correct, the relay will allow access to the settings
change or command execution. It is not necessary to enter the password every time a change is to be performed. The relay
will request the password 15 minutes after the last keypad action has taken place. This period of time is the same that takes
the relay to turn off the display backlighting.
c) LOGGING OUT (LOGOUT PWD)
To disable access to settings and commands, the user must logout.
Logout Pwd Settings
or
Logout Pwd Commands:
For safety reasons, if the user does not log out, the relay will do it automatically 15 minutes after the last keypad
action.
d) CHANGING THE PASSWORD (CHANGE PWD COMMANDS)
To set a password in the relay, both for settings and commands, the corresponding menu must be accessed inside the
Password
menu:
Change Pwd Settings
or
Change Pwd Commands:
To modify the password, the user must first introduce the existing password; if the relay has the default factory password,
this would be 0000.
For modifying the password, the relay requests the existing password with the following message:
(Setting or Command) passwd.
Login: < 0000 >
Once the entered password has been acknowledged, the new password must be entered:
(Setting o Command) passwd.
New passwd: < 1000 >
Once the new password has been entered, the relay returns to the general Passwords menu.
e) PASSWORD RECOVERY (FORGOT PASSWORD?)
If the relay passwords need to be recovered, the
“Forgot Password?”
menu must be accessed. This menu is the last
option inside the text
Passwords
menu.
This menu will show two passwords, which correspond to the encrypted protection settings, and commands passwords, as
shown in the following example:
Cod Settings: [35c0]
Cod Commands: [35c0]
<Push Enter>
In order to obtain the decoded password from the encrypted codes provided by the relay, it is necessary to contact GE
Multilin and provide these encrypted codes.
