UCI800:Maintenance documents

Solids
Sep 10 2009. Installing solids pack on 800 MHz Unity Inova.

Have two files: According to the manual for SolidsPack in Varian online user library, SolidsPack should not be installed in /vnmr directory.
 * suninovasolids.tar.Z (appears to be older)
 * inovasolids2.tar.Z

So I install it in the interested users accounts.

Magnet data reader
Sep 11, 2009. Computer failed. Hard drive is not recognized. Took the drive out, tested on another PC. The data is fine, OS is trying to boot, but hangs (b/c of hardware incompatibility?).

Fan on hard drive assembly does not work (MW-410M12S 40x40x10 mm). The fan was barely turning at 12V, added oil to the axle - works fine.

Also turns out that the key lock on the hard drive unit must be in locked position for the hard drive to start.

Air dryers

VT system
Dec 11, 2008.

VT cable connector bad: temperature cannot be regulated reliably.

Ordered non-magnetic 9 pin D Sub socket for the VT cable, Vendor: Varian, Inc. Varian part number: 5130873000 Markings on part: on five-pin side "DEMA9SNM" on the four-pin side "ITTC 0649" can be purchased from ittcannon.com, look up part by DEMA9SNM

Dec 12, 2008.

Got the replacement part from Varian.

Replaced the connector. One of the pins inside the socket one was broken.

Some of the tools I used and pin-out of the connector and wire colors are on the picture.

Dec 30, 2008

VT controller did not come up after power failure.

Removed fuse block: rectangular plastic insert right next to the power plug. There are two fulses: LF T 800 mA 250V. One was blown - the one on the top position.

Jan 5th 2009 Temporarily replaced fuse with F 800 mA 250V (fast acting) -> VT module works OK.

Jan 20th 2009 Connected house boil-off N2 to VT line as an alternative source of dry gas for chiller use.

Mar 16th 2009 Same issue as on december 30th, but after switchover from solids to liquids work. Need to order fuses.

Mar 17th 2009 Placed another fast acting fuse temporarily - VT system works OK

Apr 28th 2009 Placed proper time delay 800 mA fuse - system OK

Oxygen sensor
Monitor: AirWare from Industrial Scientific.

Sensor element: manufacturer:Industrial Scientific part number: 17050-0129 distributor: Hagemeyer North America, 12850 E. Florence Ave., Santa Fe Springs, CA 90670, tel. 310-522-3030, fax. 310-522-3040, local rep.: 888-745-6486 Debbie

12/20/08 ordered sensor.

Jan 5th 2009 Replaced the sensor.

Backup power
3000VA UPS power supply is backing up the vacuum pump (RV5) and a system monitor.

Sep 2 2009 - tested UPS. Runs 1 hour supplying power to one pump and the monitor, after that it starts beeping continuously and red light flashes, suggesting that it will run out of power soon.

Issues Jan 11 2010 - 1H sensitivity ~580 (about 30% of specification)

edit false alarm - used wrong parameters to test sensitivity :)

Fuses
I buy fuses from Socalfuse. It's a local small business.

PFG unit
Fuses protect PFG coils from overcurrent. There is one fuse per coil.

markings on the side: 1-1/4A 250V (means max rating of 1.25A at 250V with continuous safe operation, 313 is fuse series) 313 markings on ends: Mexico LF (top); IE, UL, SA (bottom - these mean standards specifications) dimensions (inches): 1.25(length) x 0.25(diameter) dimensions (mm):31.5(length) x 6 mm diameter glass body

LF means Littlefuse (company)

VT controller
LF T 800 mA 250V - slow blow 800 mA Littlefuse

cylindrical, 5 mM diameter, 21 mm length, glass body
