13.7 Numerical Listing of User Definable Trip and Signal
Functions
The events listed below are the marshalling
possibilities for signal contact inputs, signal contact
outputs, trip contact outputs, and LEDs. Some events
are for transformer protection only and some are for
the 7UT513 only.
Note:
Annunciations with a leading “>” sign are
identical with those for binary inputs and signal
or trip outputs. They represent the direct
confirmation of the binary input and are
available as long as the corresponding binary
input is energized.
