At about 0430 hrs the wet engine stopped. Tripping the solenoid due to low helium flow. As of now I cannot get it started. The controller shows M1 fault.

PVXJT is closed now.

We found 2 bad fuses in the wet engine controller. We are not sure what caused them to go but we replaced them with time-delay fuses and managed to get the engine running again. I asked KC to retrieve the spare wet engine motor/generator in the event that the motor is beginning to fail causing the fuses to blow. The system is now back to normal but recovering liquid inventory.

Discovered that compressor 1 on chiller 4 had tripped due to high oil temp. I reset the diagnostic and got it running again. If it trips again I will contact Trane. The tip off that there was a problem was the combined chiller outlet temperature was 39.39ºF and all compressors should have been running.

Comp 1 on chiller 4 tripped again on High Oil Temp. I did not reset this time. I started chiller #3 and called Trane to come fix chiller 4. 
<!-- Date: Wed Mar 14 06:13:21 2007 -->
I reported to the SciCo that the cryo system is running well and we intend to power up at 6:45.

wet engine tripped investigating.

Put pvjt loop ON. From the console reset and started the wet back up. Started OK, but sounds a little growly. Tripped again on "tack" according to the starter cabinet.

<!-- Comment: Wed Mar 14 07;03;31 comment by...Bill Noe -->
JL & KC are changing the wet engine MG since the tachometer is integral to the motor. Estimate 2 hours.



<!-- Comment: Wed Mar 14 07;32;09 comment by...Bill Noe -->
Wet engine MG swap is complete and it is running HOWEVER, we need the pulley alignment checked so we will need to shut it off when the engine guys get here.

PSM alarm 1RR21F1 It reset it'self. I informed the 2nd floor control room.

<pre>This morning I looked at the power supply in 1RR21E-2, which the one I replaced yesterday due to a bad fan within the supply itself. After I replaced the unit I had some communication   
problem with PSM. This morning I have reseated the B&B box in the supply and recovered comminication with it. I unmasked this supply in PSM and everything is green and happy.

I masked PSM 1RR18D1 at Steve Haun's request to allow them to remove an optoisolator. Then I unmasked it when he and Robeto was done.

Craig said that he heard a belt squeel on PF-1.
<!-- Author: KC -->
<!-- Comment: Wed Mar 14 11;09;26 comment by...KC -->
I paged the duty mechanic. He called and said that he would be here in about 20 minutes.


<!-- Comment: Wed Mar 14 12;03;17 comment by...KC -->
I put HVAC in LOW and disabled the RF fans to allow the duty mechanic to change the belts on PF-1
<!-- Comment: Wed Mar 14 12;30;50 comment by...KC -->
Kelly the duty mechanic is done with PF-1. He changed the 3 belts and greased the bearings. I returned the HVAC to FULL.

Plant (cryo) was recovering slowly and the dry(north) wasn't healthy( I think the #1 exhaust cam is slipping.) So we started up the EAST DRY and cooled it down, but first had to pump the vacuum on it and it's u-tubes.---->It's cold and the north is off. and we are just starting to make liquid again.

PSM alarm 1RR21F-2 channel 6. It reset it'self.
<!-- Author: KC -->



<!-- Date: Wed Mar 14 12:06:27 2007 -->
Dewar has 32.3% in it and we are making liquid at about 83l/hr, so, I put leads in run mode and put pvmf in loop control.----> seems stable but make rate dropped to 43l/hr, anyway started to power the solenoid. 
<!-- Author: Jim L -->



<!-- Date: Wed Mar 14 12:30:52 2007 -->
Going up from 3000 amps and the refrig. look steady, but our make rate slowed to 19 l/hr so, I raised the max set point on the wet to 560 rpm. --> The tach seems to be off, it reads 568 rpm but at the flywheel it's 660 rpm!---> make rate went to 33.6 l/hr and is very slowly climbing.
<!-- Author: Jim L -->


<!-- Date: Wed Mar 14 12:54:10 2007 -->
The solenoid is at 4651 amps and the cryo engines are slowly doing their thing. I informed the 2nd floor and they said that they are taking data. So all is good.

Babs went to 6 psig so under Loskot's instructions I raised the tube trailer from about 20 to 35 psig. I also slowed the wet engine from 560 to 500 rpm. The dewar is at 42.4%.

Elvis from Trane found that a fan blade on chiller #4 had broken causing the fan to vibrate loose and welded a wire to the frame of the fan motor. I got some 600v 40amp fuses from Dwight and Elvis got chiller 4 up and running in a timely fashion. He said that all of the parts are under warranty and he will bring them out when they come in.

I took different parts of the CDF systems checklist readings at different times today and things are ok now.
<!-- Author: KC -->



<!-- Date: Wed Mar 14 17:56:32 2007 -->
The CDF systems checklist and mechanical rooms are normal at this time. The cryo plant looks good also and babs & labs are holding. Dewar level is 45% and we are making liquid @ 60L/hr.

<center><h4>My *first* cryo e-log entry!</h4></center> 
As requested by Jim, here's what I did: 
<h4>Quiet-time cooling adjustments</h4> Store was dropped as scheduled at 20:00, so I decided to get a couple of things done: <ul><li>ISL Chiller setpoint has been lowered 1°C, and is now at 5°C. Let's hope that everyone stays happy with the slight adjustment... so far so good.</li> <li>SVX BHW1 had a high pressure 13.3psi (at the warning). So I could un-ignore the alarm, I changed the valve setting from 80%→72%. I did this in 2% steps, and didn't see much of a change until I hit the 72%. Flows are at 2.6 lpm and COT face pressure at 12.3 (compared to 2.8 lpm at 70% open at 13.3psi).</li></ul> This should take us well through the next store or so.
