David Wang | ITW | Repair | | | ITW water leak. |
A water leak was found on a fitting connecting ITW dump return line pressure gauge on top of exit module. TM tank flange, o-ring slot and o-ring were contaminated by water and water rust. Frank and I cleaned the flange and o-ring slot . We changed a new TM tank o-ring, vacuumed around other 3 module flanges. The leak fittings with pressure gauges were removed . I put a blind cap on removed fitting spot.. Water are switched back to ITW. No leak on blind cap. |

David Wang | ITE | Maintenance | | | Restart of ITE turbo pumps. |
PLC6 drop out in weekend caused the ITH MP1 and MP1s stopped. ITE turbo pumps were running still after that. Without back up pump, TPs started to trip off later . I found TP1,TP3, and TP4 were tripped off this morning. And , The rest pumps ran with high current draw. Jon Aoki restarted back up pumps and ITE turbo pumps. The ITE vacuum system works fine now. |
