PAS Command (Change Passwords)
The relay is shipped with factory default passwords for Access Levels 1, B,
and 2 as listed below:
The PAS sword command allows you to change existing passwords at Access
Level 2. To change passwords, enter PAS x , where x is the access level whose
password is being changed. The relay will prompt for the old password, new
password and a confirmation of the new password.
To change the password for Access Level 1, enter the following:
=>> PAS 1 <Enter>
Old Password: ********
New Password: ******
Confirm New Password: ******
Password Changed
=>>
Similarly, PAS B and PAS 2 can be used to change the Level B and Level 2
passwords, respectively.
The new password will not echo on the screen, and passwords cannot be
viewed from the device. Record the new password in a safe place for future
reference.
If the passwords are lost or you wish to operate the relay without password
protection, put the main board Password jumper in place (Password jumper =
ON). Refer to
Table 2.6 and Table 2.7 for Password jumper information.
While the password protection is disabled by setting the main board Password
jumper in place (Password jumper = ON), lost or forgotten passwords can be
assigned a new password, by using the
PAS x command at Access Level 2.
The relay will prompt for a new password and a confirmation of the new
password.
If you wish to disable password protection for a specific access level [even if
the Password jumper is not in place (Password jumper = OFF)], simply set the
password to DISABLE. For example,
PAS 1 DISABLE disables password
protection for Level 1.
Passwords may include as many as 12 characters. See Table 10.9 for valid
characters. Upper- and lowercase letters are treated as different characters.
Strong passwords consist of 12 characters, with at least one special character
or digit and mixed case sensitivity, but do not form a name, date, acronym, or
word. Passwords formed in this manner are less susceptible to password
guessing and automated attacks. Examples of valid, distinct strong passwords
include:

This device is shipped with default
passwords. Default passwords should
be changed to private passwords at
installation. Failure to change each
default password to a private
password may allow unauthorized
access. SEL shall not be responsible
for any damage resulting from
unauthorized access.
