TM4 has been moved to ITE and connected there today. I started six turbo pumps this afternoon. One of TP4 back valve (one in pairs) didn’t open .It caused the TP4 difficult to start. I disconnected that control cable that plug to solenoid valve and reconnected it. Then it works fine. After this, TP4 started to normal speed easily. The vacuum readings are OK so far. Tomorrow morning they all should be around 6-7 X E-6 torr range. Water interlock checks related to TM4 have been finished. NO water supply to ITE dump and entrance to keep the system pressure over 90psi. All TM4 water signals are good and strong by watching them from electrical panel. Gas line connected and valves opened. Control page set to fibiad .
