3.3 LED indication control
The IED 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
IED 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 IED configuration (available as output signals OUT_ST_NEUT and
OUT_OPR_NEUT).
