STATION A
=
The = prompt indicates the relay is back in Access Level 0.
The QUI command terminates the SEL Distributed Port Switch Protocol
(LMD) connection if it is established [see Appendix C: SEL Distributed Port
Switch Protocol for details on SEL Distributed Port Switch Protocol (LMD)].
SER Command (Sequential Events Recorder Report)
Use the SER command to view the Sequential Events Recorder report. For
more information on SER reports, see Section 12: Standard Event Reports and
SER.
SHO Command (Show/View Settings)
Use the SHO command to view relay settings, SELOGIC control equations,
global settings, serial port settings, sequential events recorder (SER) settings,
and text label settings. Below are the SHO command options.
You may append a setting name to each of the commands to specify the first
setting to display (e.g., SHO 1 E50P displays the setting Group 1 relay
settings starting with setting E50P). The default is the first setting.
The SHO commands display only the enabled settings. To display all settings,
including disabled/hidden settings, append an A to the SHO command (e.g.,
SHO 1 A).
Below are sample SHOWSET commands for the SEL-351A, showing all the
factory default settings (SEL-351A with an LCD: 5 A nominal current inputs,
phase and neutral).
