is not available and intended for factory use only.
The following operations are under command password supervision:
Changing the state of virtual inputs.
Clearing the event records.
Clearing the oscillography records.
Changing the date and time.
Clearing the data logger.
Clearing the user-programmable pushbutton states.
The following operations are under setting password supervision:
Changing any setting.
Test mode operation.
The command and setting passwords are defaulted to "0" when the relay is shipped from the factory. When a password is
set to "0", the password security feature is disabled.
The C30 supports password entry from a local or remote connection.
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 C30, the remote password must be used. If the connection
is to the RS232 port of the faceplate, the local password must be used.
The
PASSWORD ACCESS EVENTS
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.
The appropriate events are also logged in the Event Recorder as well. The FlexLogic™ operands and events are updated
every five seconds.
A command or setting write operation is required to update the state of all the remote and local security operands
shown above.
