Local access is defined as any access to settings or commands via the faceplate interface. This includes both keypad entry
and the through the faceplate RS232 port. Remote access is defined as any access to settings or commands via any rear
communications port. This includes both Ethernet and RS485 connections. Any changes to the local or remote passwords
enables this functionality.
When entering a settings or command password via EnerVista or any serial interface, the user must enter the correspond-
ing connection password. If the connection is to the back of the C60, the remote password must be used. If the connection
is to the RS232 port of the faceplate, the local password must be used.
For the
ACCESS LEVEL
, the "Restricted" option means both settings and commands can be accessed, but there is no
access to factory configuration. The "Factory Service" level is not available and intended for factory use only. In addition,
there are two user security access levels, setting and command, for which you 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.
The
PASSWORD ACCESS EVENTS
settings allows recording of password access events in the event recorder.
The local setting and command sessions are initiated by the user through the front panel display and are disabled either by
the user or by timeout (via the setting and command level access timeout settings). The remote setting and command ses-
sions are initiated by the user through the EnerVista UR Setup software and are disabled either by the user or by timeout.
The state of the session (local or remote, setting or command) determines the state of the following FlexLogic operands.
• ACCESS LOC SETG OFF: Asserted when local setting access is disabled
• ACCESS LOC SETG ON: Asserted when local setting access is enabled
• ACCESS LOC CMND OFF: Asserted when local command access is disabled
• ACCESS LOC CMND ON: Asserted when local command access is enabled
• ACCESS REM SETG OFF: Asserted when remote setting access is disabled
• ACCESS REM SETG ON: Asserted when remote setting access is enabled
• ACCESS REM CMND OFF: Asserted when remote command access is disabled
• ACCESS REM CMND ON: Asserted when remote command access is enabled
A command or setting write operation is required to update the state of the remote and local security operands
listed.

CHANGE LOCAL PASSWORDS
Proper password codes are required to enable each access level. When a
CHANGE COMMAND PASSWORD
or
CHANGE SET-
TING PASSWORD
setting is programmed to “Yes” via the front panel interface, the following message sequence is invoked:
1. ENTER NEW PASSWORD: ____________.
2. VERIFY NEW PASSWORD: ____________.
3. NEW PASSWORD HAS BEEN STORED.
To gain write access to a “Restricted” setting, program the
ACCESS LEVEL
setting in the main security menu to “Setting” and
then change the setting, or attempt to change the setting and follow the prompt to enter the programmed password. If the
password is correctly entered, access is allowed. Access automatically reverts to the “Restricted” level according to the
access level timeout setting values.
If the setting and command passwords are identical, then this one password allows access to both commands and
settings.
