John, Gerardo,
Gerardo was at LHO today inspecting viewports and while in the control room noticed temperature alarms at the Y end.
He found the chilled water temperatures to be way out of range (80F instead of 40F) He was able to start the second chilled water pump from the control room but unfortunately this did not start the second chiller as expected.
At the Y end chiller yard he was able to reset the second chiller and successfully start it.
Temperatures are now returning towards normal. The trip occurred Friday afternoon ~5:30. We will investigate next week.
Plot attached shows VEA temperature as well as the chilled water temperature.
