1–8 845 TRANSFORMER PROTECTION SYSTEM – INSTRUCTION MANUAL
845 ORDER CODES CHAPTER 1: INTRODUCTION
When both 845 device and server authentication are enabled, the 845 automatically
directs authentication requests to the 845
device or the respective RADIUS server, based
on user names. If the user ID credential does not match one of the device local accounts,
the 845
automatically forwards the request to a RADIUS server when one is provided. If a
RADIUS server is provided, but is unreachable over the network, server authentication
requests are denied. In this situation, use local 845
device accounts to gain access to the
845
system.
USER ROLES
User Access Levels are used to grant varying permissions to specific user roles. User roles
are used by both Basic Security and CyberSentry.
The following user roles are supported:
• Administrator: The Administrator role has complete read and write access to all
settings and commands. The role does not allow concurrent access. The Administrator
role also has an operand to indicate when it is logged on.
• Operator: The Operator role is present to facilitate operational actions that may be
programmed and assigned to buttons on the front panel. The Operator has read/write
access to all settings under the command menu/section. The Operator can view
settings from EnerVista or the front panel but does not have the ability to change any
settings. This role is not a concurrent role.
• Observer: The Observer role has read-only access to all 845 settings. This role allows
concurrent access. The Observer is the default role if no authentication has been done
to the device. This role can download settings files and records from the device.
• Factory: This is an internal non-user accessible role used for manufacturing
diagnostics. The ability to enable or disable this role is a security setting that the
Administrator controls.
GENERAL RULES FOR USER ROLES WITH CYBERSENTRY
1. The only concurrent role is Observer. If the user is logged in through serial, front panel,
or over the network, that counts as the role being logged in for concurrency reasons.
2. Both EnerVista and the front panel provide a one-step logoff. For the front panel, the
root menu has a logoff command. From EnerVista right-clicking on a device and
providing a logoff function from the context menu is sufficient.
3. The EnerVista Login Screen has “User Name:” and “Password:” fields for the default
remote (Radius) authentication, but when a “Local Authentication” checkbox is
selected the “User Name:” field changes to a drop down menu where the user can
select one of the predefined roles on the 845.
845 Order Codes
NOTE:
Support of some of the features described in the "Setpoints" section are order code
dependent. Each 8 Series unit is ordered with a number of required and optional modules.
Each of these modules can be supplied in a number of configurations specified at the time
of ordering.
NOTE:
Refer to https://www.gegridsolutions.com/multilin/catalog/845.htm for available order
code combinations.
The information to specify an 845 relay is provided in the following Order Code figure:
