We have frame V GT. Currently 20DV is not hardwired in (MarkVi to MarkVIe upgraded) new system. 20DV is wired in the field. 20DV is configured in Mark Vie but its terminals are open. It is like this for long time .
As mentioned above, 20DV was never in line since GT commissioning. I have recently joined the plant, and I have been assigned to take 20DV in Mark Vie.
Can somebody give me an insight on importance of 20DV? And as I said it was never in line in Mark Vie, then how was GT running without it?
Please guide me in what to look for as I am totally new to Mark VI?
