For example, the default name for contact output OUT101 is OUT101. You could
change the default name to an alias, BK1_TR, for example.
Alias settings consists of a single freeform settings category. As many as 200
aliases may be assigned. The default alias configuration is relay specific. See the
relay instruction manual for the default aliases. Figure 12.2 shows an example
using the SET T command to set two aliases.
Protection Freeform SELOGIC Control Equations
Protection freeform SELOGIC control equations are in Classes 1 through 6 corre-
sponding to settings Groups 1 through Group 6 (see Multiple Setting Groups on
page 12.4).
As many as 250 lines of freeform equations may be entered in each of six settings
groups, although the actual maximum capacity may be less. See SEL
OGIC Con-
trol Equation Capacity on page 13.5 for more information. The default configu-
ration of the protection SEL
OGIC control equations is relay specific. See the
product-specific instruction manual to see the defaults.
Automation Freeform SELOGIC Control Equations
Automation freeform SELOGIC control equations are in Blocks 1 through 10.
NOTE: Some versions of some
SEL-400 series relays have only one
automation setting block with a
capacity of 100 lines of automation
freeform SEL
OGIC control equations.
SEL-400 series relays do not contain any automation freeform SELOGIC settings
in the factory-default settings.
The relay has a capacity of 100 lines of automation freeform SEL
OGIC control
equations in each of 10 automation setting blocks. See SEL
OGIC Control Equa-
tion Capacity on page 13.5 for more information.
