Interfaces
There are two methods of interfacing with the 845.
• Interfacing via the relay keypad and display.
• Interfacing via the EnerVista 8 Series Setup software.
This section provides an overview of the interfacing methods available with the 845 using
the relay control panel and EnerVista 8 Series Setup software. For additional details on
interface parameters (for example, settings, actual values, etc.), refer to the individual
chapters.
FIRST ACCESSING THE RELAY
When first accessing the relay, log in as Administrator either through the front panel or
through EnerVista connected serially (so that no IP address is required). Use the default
password (the default password is "0").
Basic Security
If the relay is in the commissioning phase and you want to bypass authentication, switch
the "Setpoint access" setting on or assign it to a contact input. Once the setting is on, you
have complete administrator access from the front panel. If a contact input is chosen, the
access is also conditional on the activation of the respective contact input.
For more information on setpoint access and other security features available with basic
security, refer to the Basic Security section in the Setpoints chapter.
CyberSentry
If logging in through EnerVista, choose Device authentication and login as Administrator.
Note: If the relay is in the commissioning phase and the user wants to bypass
authentication, the user may use the setpoint access feature to gain administrative access
to the front panel in the same way as with basic security (see the "Basic Security" section).
For more information on security features available with CyberSentry, refer to the
CyberSentry security section in the Setpoints chapter.
