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.
