LED Targets

The LED targets on the front panel of the relay can be
controlled by the functions in section Table 13.1. One
LED indicates that the relay has power, while another
indicates when the relay is blocked. The other LEDs
can be configured. An LED lights when one of its
functions becomes active, and can be configured to
remain lit until reset (memorized, m) or only until the
function becomes inactive (not memorized, nm). The
7UT512 relay has six programmable LEDs, while the
7UT513 relay has 14.

6305 LED 5
6306 LED 6
6307 LED 7 (7UT513 only)
Each LED can be independently lit by up to twenty functions (chosen from the list in Table 13.1). Each
function can cause the LED to remain lit until deliberately reset (memorized, m) or go out once the function is
no longer active (not memorized, nm) unless, of course, another function lighting the LED is still active. The
default configuration is listed below:

Buchholz warning
Buchholz trip
Alarm functions have effect only when the
corresponding protection function is enabled and
active. Functions with a ">" sign prefix can be
assigned to both signal contact inputs and signal
contact outputs to pass a signal through the relay
independent of the relay's protective functions (of
course, the relay must be operational).
