TM4 has been connected at CS. Turbo- pumps and water system are started and running . The HV cover has been installed on the module. Everything is good
so far. |

Thursday, September 24, 2015, 07:00, David Wang, Conditioning Station, Maintenance, TM4, Ta#46, Turned off TCS all vacuum pumps and water pumps.
|
TCS:MP1 back up pressure went up too high (700mtorr).I turned off all the pumps.The TCS is under vacuum still. TCS water package cooling fans showed
error on control page.The water pumps are stopped also.
Restarted the vacuum pumps 40 minutes after stopping. Everything is back to normal. The MP1 back up pressure need to be monitored frequently before |

Friday, November 06, 2015, 14:35: Roughing
Turbos was started around 4pm. Later it was found that the manual valve for the two turbo pumps on the service cap was closed. The valve was open
and pumping resumed. The roughing vacuum was high and increased into Saturday morning. The vacuum system was switched off on Saturday. |

|
Service cap leak checked this afternoon. Found multiple leaks of 10E-8 to 10E-7 range. Connected to the backing line with IG1 at ~4E-6 T, CG1A around
40 mT. Got responses around large round flange on top, rectangular side panels, water f/t on GND and water f/t on HV. Will resume leak checking tomorrow
to attempt to pinpoint sources of leak more accurately. |

Tuesday, November 10, 2015, 10:23, Anders Mjos, Conditioning Station, Maintenance, TM3, , Air to vacuum leak on service cap
|
Conducted a more thorough leak check this morning with Edi. He found a leak on the base of the blue F/T insulator for the multi-pin connector (see
attachment). I discovered that all the bolts could rotate freely in the threads as they were too small. The bolts were replaced. The leak rate was reduced
but still significant. The o-ring will likely need to be replaced. |
