 Wed May 2 16:28:16 2007, Doug Preddy, Normal Running, Energizing solenoid to 500 amps
|
Power supply initially would not ramp up. I exercised the rate control
selector switch and found that the power supply would ramp up at only the
30 minute setting. It is ramping up at a rate of about 60 minutes. |

Sat Jun 16 15:05:03 2007, Doug Preddy, Normal Running, Solenoid power lead temp problem
|
Power lead temps rippling and increasing. I asked an operator to cycle
HIC142. This seems to have fixed the problem (for now). |

Sun Jul 1 16:09:37 2007, Doug Preddy, Normal Running, M9B:DP2 tripped off
|
Diffusion pump tripped off and vacuum (and power lead temps) going up. I
had an experimentor cycle HIC 142 at 4:15 this morning. When I got in
today I restarted the pump and it is back to 6.0 x 10-7. Power lead temps

The power leads temps are starting to cycle again. Earlier today M9
experimentor cycled HIC142 to stablize the oscillations. They started
again early this morning, so cycled HIC142 again. Oscillations died back,

got a page for the power lead temp
came down and cycled the power leads.. did not seem to make a difference..

Tue Oct 2 13:02:37 2007, Doug Preddy, Normal Running, PLC problems
|
While downloading new code for 2A PLC the M9 and M15 vacuum systems were
shut off. This is due to the two systems piggybacking onto the 2A PLC.
When M9 Epics came back up there was no controls. Eventually I reset the

About 10 hours ago the power lead temperatures started to fluctuate and
climb.
I cycled CV142 and the Temps have dropped and stablized. |

Mon Nov 26 09:45:43 2007, Doug Preddy, Normal Running, power lead problems
|
Power lead temperatures were rippling yesterday afternoon. I asked one of
the operators to cycle CV142.
The temperatures were rippling again this morning, so I cycled CV142. |

Tue Nov 27 21:02:08 2007, Doug Preddy, Normal Running, power lead ripples

power leads were oscillating tonight. John K. came down and cycled CV142.
(Thanks John!) Temps settling out. |

Mon Apr 28 09:03:22 2008, Doug Preddy, Normal Running, power leads warmed during weekend
|
The power lead temperatures suddenly rose on Sunday morning. No rippling occured before the woarm up.
I shut flow off this morning for about 10 minutes
(until the LHe in went up to 30K) and then open the flow back up. The temperature seem to be recovering. |

Tue Jul 15 08:47:13 2008, Doug Preddy, Normal Running, Screen grab of normal running

| Solenoid was recovered on Sunday July 13. The power leads started to ripple slightly this morning, so I cycled HIC142. No real change. |

| Solenoid power supply will be turned off for Fall shutdown. |

Sun Oct 5 11:12:48 2008, Doug Preddy, Normal Running, M9B:V1 interlocks and a IOC crash
|
M9A:V1 was removed this shutdown. It's "in" limit is required to allow M9B:V1 to be opened. I have bypassed the interlocks on M9B:V1 until the M9A:V1 limits
can be jumpered. Don Dale and George Clark have been informed.
Also an IOC crashed so the data pages were not updating. Evgeny rebooted the IOC. All is
now fixed. |

Wed Nov 5 16:33:52 2008, Doug Preddy, Normal Running, sbplc light out
|
| On main menu the sbplc light was black. All vacuum systems looked good, but there was no control of any device. Jane reset the IOC. It is hosted by sundance. |

I had distributed this list by email earlier this month. I have added
a few items at the bottom. I am posting it on the M9SOL Elog under
Maintenance. Some of the items may not be achievable or practical but
