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.
Power lead temps rippling and increasing. I asked an operator to cycle HIC142. This seems to have fixed the problem (for now).
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 also are going down.
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, but are still present. Will try and warm the power leads later today when the experiment's sample is changed.
got a page for the power lead temp came down and cycled the power leads.. did not seem to make a difference.. Kevin
There are two strip tools saved: coils powerlead
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 local/remote switch (thumbwheel #100) to button #1 being on. Mike Leross added a text and light on the epics vacuum page that says "EPICS works only when green". If this light is not green, dial thumbwheel #100 and push button #1. Make sure the light comes on and you should have EPICS control back. This caused a glitch in the refrigerator system. It did not trip it off, but it would have if the solenoid was energised. The panel showed compressor fault and the temps for TI121, and the powerleads all jumped. This may be a cause for some of our unknown problems.
About 10 hours ago the power lead temperatures started to fluctuate and climb. I cycled CV142 and the Temps have dropped and stablized.
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.
power leads were oscillating tonight. John K. came down and cycled CV142. (Thanks John!) Temps settling out.
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 I thought it would be a useful first attempt at a To-Do list.
