3.2.2 Functionality
The protection relay includes a global conditioning function LEDPTRC that is used
with the protection indication LEDs.
LED indication control should never be used for tripping purposes.
There is a separate trip logic function TRPPTRC available in the relay
configuration.
LED indication control is preconfigured in a such way that all the protection function
general start and operate signals are combined with this function (available as output
signals OUT_START and OUT_OPERATE). These signals are always internally
connected to Start and Trip LEDs. LEDPTRC collects and combines phase
information from different protection functions (available as output signals
OUT_ST_A /_B /_C and OUT_OPR_A /_B /_C). There is also combined earth
fault information collected from all the earth-fault functions available in the relay
configuration (available as output signals OUT_ST_NEUT and OUT_OPR_NEUT).
