[Dsg-hallb_magnets] Hall B Solenoid - Update on SOE relay string / dump switch operation check out

[Pablo Campero]

Hi Ruben, 

1. Yes, the wiring for the water flow switches has been corrected and they are working properly. 

2. I already returned all the limits in the Crycon units back to the original set values. 

Best Regards, 
Pablo

Probir, Mike, 

Can you now complete the rest of the list that I shared with you - i.e. fitting G10 box and so on? 

Please do not remove the hose connected between the water cooled lead ends - that must stay in place - however please drain the water-cooled leads. 

Pablo, 

I also understand that the water flow switches has incorrect wiring and that Scot has now corrected this? 

Will you now be setting all the Cryocon limits (and any other limits that you adjusted to carry out these tests) back to their original values? 

Regards 

Ruben

Hello Ruben, 

Current Lead Water Flow test was completed. 
A wire jumper on the terminal block (Remote control rack) was blocking the MPS to trip (Open Dump Switch), but Scot solved this issue and we completed the full test successfully. Attached find the updated spreadsheet with the details of the Test. 
The hose connected between the water cooled leads ends can be removed. 

Nick, 
You are now enabled to pull out the SOE module to make the Display SOE test. As you can verify on the attached spreadsheet, channels 0 to 7 are not working properly, the remain channels seem to be working well. 

Best Regards 
Pablo

Excellent thank you. 

I believe Mike may have checked out the water flow rates this morning - please check with him that the relevant test is now complete. 

Let me know when it is complete. 

Cheers 

Ruben

Hello Ruben, 
Attached find the updated spreadsheet with the results of the QD - SOE and MPS Dump Switch functionality Test. 

Nick, 
We did not complete with the Water Cooled Leads Flow Test, will continue the test on Monday (05//08/17). 
After that, you will be able to pull out the SOE module and go ahead with your point testing hardware for the SOE module display. 

Best Regards, 
Pablo

Hi Brian, 

I will be in the hall with Pablo again this afternoon flow water flow test in the hall..! 
Please come over. 
We did the tests with our QD after the interlock issue that was from the Lead temp...! 
Pablo has taken care off and we have completed our tests on the QD successfully. 

Please come over to the hall and see if we can get hold of Mark. 

Regards 

Probir
