Could someone explain the difference between a Trip/Close control & a Raise/Lower in a RTU? This came up in a GE RTU, but believe most RTUs have these different control types.
I understand you would use a T/C for circuit breaker or other device you want to open & close & that the R/L would be more for pulsing up or down something (tap changers etc) but would both these just be a contact close pulse for a certain time? Why are these two types of controls wired differenlty on an RTU control board & programmed differently in the RTU & SCADA software?
Thanks in advance.
