ABB Relion REC615 - Programmable Leds; Function Block; Functionality

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).
