Table 3: Event Report Parameters
Parameter Description
n
Choose event number (1-28). Defaults to 1 if not
specified.
A
Specifies that the analog section of the event is to be
displayed (current, voltage, frequency, contact outputs,
and optoisolated inputs).
D
Specifies that the digital section (Protection and Control
Elements) of the event is to be displayed.
Summary event information can be viewed at the control front-panel
LCD using the front-panel pushbuttons. Press the EVENTOS
pushbutton (primary function) and the appropriate left/right and up/down
pushbuttons (secondary function) to view event information.
If no parameters are issued with the EVE command, then you will
automatically receive both the analog (A) and digital (D) sections of the
event report.
Access Levels and Password Protection
Issue serial port commands to the SEL
-
351P to view metering values,
change recloser control settings, obtain event information, etc. The
available serial port commands are listed in Table 2. The commands can
be accessed only from the corresponding access level as shown in the
table, but a higher access level can access the serial port commands in a
lower access level.
Access Level 0 (the lowest access level)
Access Level 1
Access Level E (EZ access level)
Access Level B
Access Level 2 (the highest access level)
As a security measure, entry to a particular access level (except Access
Level 0) requires a unique password. This allows the user to set up a
password system to deny unqualified or unauthorized personnel access
to higher levels.
The SEL-351P ships from the factory with default passwords (see Table
4). If restrictions are to be placed on personnel using the SEL-351P, the
factory default passwords must be changed. Make sure that password
information is stored for future reference in the event that it is lost or
forgotten.
