Since yesterday around 4pm. Due to attempt to use the TMS:ER0 device.

IOC rebooted this morning. Archivers restarted.

Monday, May 12, 2014, 10:02: Jane R. power cycled the hardware. EPICS is back up. Sources archiver required a restart.

 Likely caused by the PLC. e-fault  8139

Wednesday, May 20, 2015

Dave Morris re-established contact with controls. (PLC IOC was down).

Everything shut down, while EPICS showed everyhing to be on.

Controls group (Dave Morris) has reestablished contact. System is operations.

Evgeniy and Kazuya investigated the problem with TSH:TGHT readbacks and they came to the conclusion that the PS is faulty, and the PLC reads correctly the signal sent by the PS.  Kazuya is redirecting the E-Fault from Controls to PS.

Ray Dube estimated few weeks (4-6) to send the PS offsite for repairs. This needs to be scheduled. For the time being, one can use the Test Stand with the PS setpoints, displayed on its front panel, as a reference.

There was a previous DI CU-LCW  pump trip as per the above elog. The CU-LCW pump was configured this morning. The water pressure is set to 80 PSI as per the MCR. Any further can overload & trip the pump. 

Thursday, February 18, 2021, 10:55: Current flow rates & pressure read at the TS

DI water pressure as per the gauge on the supply side of the FS#2-5 manifold @ 85 PSI.

Noticeable flow rate reduction based on previous target conditioning logs. Previous pressure was around 100 PSI.

Tuesday, February 09, 2021, 13:43: DI water flow completely stopped.

Control room contacted. DI water loss confirmed.

Tuesday, February 09, 2021, 13:52: DI water flow returned.

Control room contacted. DI water loss due to a "seamless" pump change over for the DI water supply & mechanical services. The supply was transferred over to a new pump which overloaded and failed. They had to switch back over to the (old) pump. Mechanical services will still try to do the switch over again. Either tomorrow or the day after. Running the TS up to 580A until then is not recommended.  Control room to update tomorrow morning.

Fault# 13773: Cu-LCW south SA3-03 tripped on motor overload.

Installed Cu-shunts on TGHT and TBHT terminals. HS water looped.
