Front Panel Operation Chapter 3
Front Panel Security
Front Panel Access Levels
The relay front panel typically operates at Access Level 1 and allows any user to
view relay measurements and settings. Some activities, such as editing settings and
controlling output contacts, are restricted to those operators who know the relay
Access Level 2 password when enabled. The factory default setting for the Access
Level 2 password is “DISABLED”, which provides unrestricted access.
In the figures that follow, restricted activities are marked with the padlock
symbol, shown in Figure 25.

Before you can perform a front panel menu activity that is marked with the
padlock symbol, you must enter the correct Access Level 2 password. After
you have correctly entered the password, you can perform other Access Level 2
activities without re-entering the password.
Access Level 2 Password Entry
When you try to perform an Access Level 2 activity, the relay determines whether
you have entered the correct Access Level 2 password since the front panel
inactivity timer expired or since the “Reset Access Lvl” command has been
executed from the Main Menu. If you have not, the relay displays the screen
shown in the Password Entry screen shown in Figure 26 for you to enter the
password.
