4.2.9.4 Control of one breaker
For this application, the relay is connected and programmed for breaker 1 only. Operation for this application is identical to
that described in the previous section for two breakers.
4.2.10 Change passwords
The information in this section refers to password security. For information on how to set the password for the first time or
change CyberSentry passwords, see the previous chapter or the Settings > Product Setup > Security > CyberSentry section
in the next chapter.
The D30 supports password entry from a local or remote connection.
Local access is defined as access to settings or commands via the front panel. This includes both keypad entry and the
RS232 port. Remote access is defined as access to settings or commands via any rear communications port. This includes
both Ethernet and RS485 connections. Any change to the local or remote password enables this functionality.
When entering a settings or command password via EnerVista or any serial interface, the user must enter the
corresponding connection password. If the connection is to the back of the D30, the remote password must be used. If the
connection is to the RS232 port of the front panel, the local password must be used.
There are two user security access levels, setting and command, for which you can set a password for each. Use of a
password for each level controls whether users can enter commands or change settings. Another option is to specify
setting and/or command access for individual user accounts.
• Setting — Allows the user to make any changes to any of the setting values:
– Changing any setting
– Test mode operation
• Command — Restricts the user from making any settings changes, but allows the user to perform the following
operations:
– Operating the breakers via front panel keypad
– Changing the state of virtual inputs

(1)
USER 2 OFF/ON
To Close BKR1-(Name)
If the USER 2 key is pressed, this message appears for 20 seconds. If the USER 2 key is pressed
again within that time, a signal is created that can be programmed to operate an output relay to
close breaker 1.
(2)

selected. Three possible actions can be performed from this state as per (1), (2) and (3). Repeatedly
pressing the USER 1 key alternates between available breakers. Pressing keys other than USER 1, 2,
