Use the SHOW command to view relay settings. The SHOW command is
available from Access Level 1 and Access Level 2. Table 6.2 lists the SHOW
command options.
You may append a setting name to each of the commands to specify the first
setting to display (e.g., SHO 50P11P displays the relay settings starting with
setting 50P11P). The default is the first setting. The SHOW command
displays only the enabled settings.
Enter Settings
The SET command (available from Access Level 2) allows you to view or
change settings. Table 6.3 lists the SET command options.
You may append a setting name to each of the commands to specify the first
setting to display (e.g., SET 50P1P displays the relay settings starting with
setting 50P1P). The default is the first setting.
When you issue the SET command, the relay presents a list of settings one at
a time. Enter a new setting or press <Enter> to accept the existing setting.
Editing keystrokes are listed in Table 6.4.
