Command Definitions
The relay prompts for each setting in the order specified in the SEL-587Z
Settings Sheets in Section 5: Setting the Relay.
The relay performs limit checks as each value is entered. The limits for each
setting are specified in the Settings Sheets. If a setting is out of limits, the relay
responds “Out of range” and prompts for the value again.
After you enter a setting successfully, the relay will prompt you for the next
setting in the class. After you have entered all settings in the class, the relay
performs secondary settings checks to verify that the settings are in order. If a
settings check fails, the relay displays a warning message and prompts for the
settings value that caused the warning condition. If more than one setting
value fails, the relay prompts for the first settings value that failed.
After you have entered the last setting in the class and settings have been
modified, the relay displays a listing of the settings and then responds “Save
changes (Y/N) ?” If you type “n” or “N,” the relay does not save the changes
and responds “Settings aborted.” If you type “y” or “Y,” the relay saves the
changes and responds “Settings saved.” The relay response is the same when
no settings are changed.
Use the TER option to inhibit the relay from sending the setting class or
instance readback when you end a setting session. SEL recommends that you
use the TERSE option sparingly; you should review the readback information
to confirm that you have entered the settings that you intended. You can use
the TERSE option in any command at any position after typing SET. When
you end the setting edit session, the relay responds, “Save settings (Y,N)?” If
you answer Y<Enter>, the relay pulses the alarm contact, saves the new
settings, then responds “Settings Saved.” If you answer N<Enter> to the save
settings prompt, the relay responds “Settings aborted.”
For example, to set the differential element 87A2 pick-up value, enter the
following:
Set 87A2P <Enter>
