Password
The relay uses passwords to control access to settings and control menus. The
relay has six access-level passwords. See Changing the Default Passwords on
page P.10.6 for more information on access levels and setting passwords. The
front panel is at Access Level 1 upon initial power-up and after front-panel
time out.
Password validation occurs only when you request a menu function that is at a
higher access level than the presently authorized level. At this point, the relay
displays a password entry screen, shown in Figure 7.13. This screen has a
blank password field and an area containing alphabetic, numeric, and special
password characters with a movable highlight box.
Figure 7.13 Enter Password Screen
Enter the password by pressing the navigation pushbuttons to move the
highlight box through the alphanumeric field. When at the desired character,
press ENT. The relay enters the selected character in the password field and
moves the dark box cursor one space to the right. You can backspace at any
time by highlighting the
BACKSPACE character and then pressing ENT. When
finished, enter the password by highlighting the
ACCEPT option and then
pressing ENT.
If you entered a valid password for an access level greater than or equal to the
required access level, the relay authorizes front-panel access to the
combination of access levels (new level and all lower levels) for which the
password is valid. The relay replaces the password screen with the menu
screen that was active before the password validation routine. When you enter
Access Levels B, P, A, O, and 2, the Relay Word bit SALARM pulses for one
second.
If you did not enter a valid password, the relay displays the error screen shown
in Figure 7.14. Entering a valid password for an access level below the
required access level also causes the relay to generate the error screen. In both
password failure cases, the relay does not change the front-panel access level
(it does not reset to Access Level 1 if at a higher access level). The relay
displays the
PASSWORD INVALID screen for five seconds. If you do not want to
wait for the relay to remove the message, press any of the six navigational
pushbuttons during the five-second error message to return to the previous
screen in which you were working.
