Archiver restarted.

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

Restarted archivers.

The ground connection between B and F (ISK4523D Rev 6) was found burnt off. It will be switched out as per CATHODE BIAS configuration (ISK4563D Rev 3) by Ray D.

As per ISK4562 Rev 3 and ISK4563 Rev 3

The performance of the roughing pump has gradually gone down. Notably after the system has been vented. See attached screenshot from the archiver. E-fault 7258.

 Edi replaced the backing pump on June 5th.

A water leak on MB1 was found and reported by operations on June 10th e fault 7429

MB1 can not be switched on due to an TSH:MB1 water flow trip. Paddle wheel is rotating.

Wednesday, June 18, 2014, 14:03: Paddle wheel replaced with a used one from beam lines. Model SST150. Signal recovered.

Upon inspection it was found that the bolt attaching the FC to the actuator had fallen off. The bolt was reattached and FC0 can be actuated in/out again.

The read back of the ANODE current was confirmed to be working today with help of Ray D. using a 1kOhm resistor. There is an offset in the read back which can explain why no current was seen on SiC#30. The resistor between CATHODE and GND was changed from 100 kOhm to 50kOhm.

Travis assisted in installing a temperature reading RTD from Omega (SA1-RTD-MTP) on the water supply. The RTD has been installed with a 503 Ohm resistor => 0V = -175.75 C, 10V = 205.71 C. The RTD has been connected to Ch 9 on the data logger.

Offset calibration data towards the SUPPLY temperature reading is attached.

since yesterday around 19h. See attached screen shot of archived data

Thursday, August 14, 2014, 08:40: Rebooted IOC. Still reading full scale only. FC0 reads full scale with signal cable removed.

Thursday, August 14, 2014, 11:28: Graham called to inform me that all of the 8 channels on the module was reading high. TRIUMF does not have a spare. He will arrange to have the module repaired.

Tuesday, August 19, 2014, 16:27: Graham has brought the system back into operation with a new vqsx module from the ICB stand.

Possible controls problem. Breaker 18 found latched. Can not be re-energized. Burnt smell in PLC / HV area. e-faut 7561

Thursday, August 21, 2014: Dave Morris had a look and was able to isolate the problem to be with one of the low voltage power supplies in the PLC panel.

Friday, August 22, 2014: New 12V and 24V power supplies installed. PLC cabinet vacuumed. A new 24V fan with filter will also be installed.

Tuesday, August 26, 2014: Power restored to PLC cabinet. System is operational again.
