• Passwords must be 6 to 20 characters in length
• Passwords must contain characters from three of the following four categories:
- English uppercase characters (A through Z)
- English lowercase characters (a through z)
- Base 10 digits (0 through 9)
- Non-alphabetic characters (for example, ~, !, @, #, $,%, &)
PASSWORD RECOVERY PROCEDURE
In the event of losing all passwords, the 845 can be reset to factory defaults by following
the procedure below:
1. The customer sends an email to the customer support department providing a valid
serial number and using a recognizable corporate email account.
2. Customer support provides the customer with the code to reset the relay to factory
defaults.
3. The customer enters the code provided from the front panel, under the menu
Setpoints > Device > Installation > Service Command
defaults.
Note that even an Observer may execute this operation.
• The current limitation for the maximum number of Observer sessions from EnerVista is
three when the Communications card is present.
• When the communications card is not present, a maximum of two Observer sessions
may be initiated through EnerVista. If two Observers are connected, a third
connection is only allowed for an Administrator user. No Operator has access.
However, if an Operator is first connected, before any other user, only one Observer is
allowed and not two, so that an Administrator may always be able to connect. This is
because the maximum number of TCP connections from EnerVista, when the
Communications card is not present, is only three. (With a Communications card, the
maximum number of TCP connections is five.)
The 8 Series Basic Security supports three roles: Administrator, Operator and Observer.
The Main Settings Structure is available from Path:
LOGIN
The setting allows a user to login with a specific role.
1. Whenever a new role is logged in, the user is prompted with a display to enter
password.
2. If the user enters the wrong password, an "Authentication Failed!" message is
displayed
3. If the maximum failed authentications occur an "Account Blocked!" message is
displayed.
4. The Observer is the default choice and it does not require a password.
LOGOUT
This setting logs out the current user and logs in as Observer. If the user is already an
Observer, this setting does not apply. When logging out, a switch to Observer role is
performed.
CHANGE PASSWORDS
1. The Change local passwords menu is shown on the front panel and EnerVista on a
successful login of Administrator role.
2. If password complexity is enabled, the rules as defined in the Password Complexity
section must be obeyed. If password complexity is disabled this setting accepts 1 to
20 alphanumeric characters.
