Update RICH_Lo_Rmp
HVConstants.py update RICH_Lo_Rmp
The rate has been set to lower since then. So, just get rid off this tag from the table list.
Add the HVMUOnly in the table list on Wikipage

Update tag HVTest_DRZD_Fill_B500
HVConstants.py update HVTest_DRZD_Fill_B500
Can deal with OFF and RUN now.

Tested the board #8
Still the same problem. channle 20 draws no current.
Message from John Dobbins:
I think there are two possibilities. 1) ADC has a bad channel. 2) The output relay on that channel is not working properly. We should rule out possibility (2) by independently measuring the load current when we attach a load to this channel. Depending on your set-up you may already be doing this. I'll stop by and you can describe the test set-up to me in a little more detail. For example, can you disable the other channels on the same bulk supply? Then a) bulk also reads zero with load because relay is bad (i.e. load not really connected) or b) bulk reads expected current but channel still reads zero -> bad ADC
Tested the channel 20 by disabling the other channels. The result is that bulk also reads zero. So the load is not really connected.
Message from John:
Sounds like the ADC is OK. The relay could be bad or the cable/load could be bad. Can you try the cable/load on a different bulk on this board or on a different board?
Label the cables and replugged them into the load. Test the cables are OK. Need schematics to diagnose.

Test board #8
Ji suggested to swap the 5th channel with the others and test that again. Before doing that, I made a normal test. All of the channels are getting normal this time. I tested all of the three bulks and they all functioning well.
Then I kept the high voltage - 2100V - on the bulk 2, after about 3 minutes, the bulk reported trips on the terminal window. I tried relatively lower voltage, i.e. 500V, 1500V, they were all OK. Finally, I retested it for 2100V, and bulk tripped after 3 minutes again. No individual channel trip noticed.

Not sure about the DRCA. Ask Dan.

Board
Message from John:
The circuitry that generates the HV has two portions. The low voltage portion shown on sheet 9/10 of Drawing 1469-1 and the rectifier stack on sheet 3/4 of drawing 1469-1N&P. We will need to examine signals with the board fully assembled and HV on. Are the components on sheet 9/10 of Drawing 1469-1 accessible with the board assembled?

Update Tag HVTest_DRZD_Fill_B500
Message from Dan:
The DRCA should be set to 370 for both Fill and Run for any kind of run configuration, unless the DR is turned off. If the DR is off, the DRCA should be off.
HVConstants.py update HVTest_DRZD_Fill_B500
Done.
Update Tag HVTest_DRZD_Fill_B300
HVConstants.py update HVTest_DRZD_Fill_B300
Done.

Test board
- John and I looked throughout the schematics. He suggested me to test it again by recovering the chips with non-conducting tapes.
- Before doing the test, I took anther look at the board. There was a trace broken close to the ADC chips.
- I took this to Margie and we figured out that the trace should be connecting the resistor R89 to the pin 5 on the ADC. So, we made a jumper and reconnected them.
- Then I tested the board's bulk 2 again. At 2100V, no trip appeared up to 10 minutes. The current in the bulk and channels are:
| Bulk | Ch 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | Total |
|---|---|---|---|---|---|---|---|---|---|
| 34.4 | 4.31 | 4.27 | 4.28 | 5.18 | 4.29 | 4.23 | 4.25 | 4.25 | 35.06 |
The Ch19 has higher current than others. The "Total" means add up all the eight channels' current. As the Total current is higher than the bulk current, it means they are measuring independently.
- To make sure that the load is fine, I tested the bulk 0. At 2100V, the current looks like:
| Bulk | Ch 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | Total |
|---|---|---|---|---|---|---|---|---|---|
| 34.1 | 4.22 | 4.21 | 4.25 | 4.19 | 4.20 | 4.18 | 4.20 | 4.20 | 33.65 |
It indicates that the load is OK.
