Target LEDs
The SEL-421 gives you at-a-glance confirmation of relay conditions via opera-
tion and target LEDs. These LEDs are located in the middle of the relay front
panel. The SEL-421 provides either 16 or 24 LEDs depending on ordering
option.
Section 4: Front-Panel Operations in the SEL-400 Series Relays Instruction
Manual describes the general operation and configuration of these LEDs. In the
SEL-421, targets latch when a trip occurs. For a concise listing of the default pro-
gramming on the front-panel LEDs, see Front-Panel Settings on page 8.35.
Use the slide-in labels to mark the LEDs with custom names. Included on the
SEL-421 Product Literature CD are Customer Label Templates to print labels for
the slide-in label carrier.
