Operation and Target LEDs
Programmable LEDs
The SEL-700G provides quick confirmation of relay conditions via operation
and target LEDs. Figure 8.24 shows this region with factory-default text on
the front-panel configurable labels. See Target LED Settings on page 4.232 for
the SEL
OGIC
control equations.

Protection Relay
You can reprogram all of these indicators except the
ENABLED
and
TRIP
LEDs
to reflect operating conditions other than the factory-default programming
described in this subsection.
Settings T0n_LED are SEL
OGIC
control equations that work with the
corresponding T0nLEDL latch settings to illuminate the LEDs shown in
Figure 8.24. Parameter n is a number from 1 through 6 that indicates each
LED. If the latch setting (T0nLEDL) for a certain LED is set to N, then the
LED will follow the status of the corresponding control equation (T0n_LED).
When the equation asserts, the LED will illuminate, and when the equation
deasserts, the LED will extinguish. If the latch setting is set to Y, the LED will
only assert if a trip condition occurs and the T0n_LED equation is asserted at

NOTE:
There are three versions of

configurations depending on the
model (SEL-700G, SEL-700GT, or
SEL-700GW).
NOTE:
The target LEDs are restored
to their previous state after the relay
