IGH issue: might have been fixed
Nick Dent responded that the error shows issue with electrical circuits in IDR or IGH unit and they donot provide further support for repairs.
Tried unplugging the IDR from Goldman's lab (to plug it into ours) Proceeded with opening up IGH as well. Plugged it into ours.

IDR displaced SOS errors for a long time (~ 3 hrs) but then started settling down. Current state: Valves can be opened/closed. He4 pump can be started.
There is a clicking sound when we started the He4 pump, investigating if that can cause the IDR to fail again.
Plan is to recover the mixture and cooldown once the electronic locks are back online in the buidling.
