Description of Commands
SET
Use the SET command to change relay settings. The SEL-421 settings
structure is ordered and contains these items (in structure order): classes,
instances, categories, and settings. An outline of the relay settings structure is
as follows:
Classes (Global, Group, Breaker Monitor, Protection, Automation,
Outputs, Front Panel, Report, DNP, and Ports)
Instances (some classes have instances: Group = 1–6; Protection = 1–6;
Automation = 1–10; PORTs = 1–3, F, 5)
Categories (collections of similar settings)
Settings (specific relay settings with values)
The SET and SHOW commands contain these settings structure items, which
you must specify in order from class to instance (if applicable) to setting. For
more information and a tutorial on setting the relay, see Making Simple
Settings Changes on page U.4.13.
The order that specific settings appear in the relay settings structure is factory
programmed. See Section 10: Settings for specific settings order, ranges, and
default values.
SET
The SET command with no options or parameters accesses the relay settings
Group class and the instance corresponding to the active group. To set a
different instance, specify the instance number (1–6).
The relay validates your settings entries as you enter each setting. At the end
of a settings instance session, the relay responds with a readback of all the
settings in the settings instance; then prompts,
Save settings (Y,N)? If you
answer Y <Enter>, the relay pulses the Relay Word bit SALARM, and
responds,
Saving Settings, Please Wait........... The relay saves the
new settings, then responds,
Settings Saved. If you answer N <Enter> to the
save settings prompt, the relay responds,
Settings aborted.
SET A
Use the SET A command to set the Automation SELOGIC control equations.
See Section 3: SEL
OGIC Control Equation Programming for more information
on SEL
OGIC control equations.
