[Hallb-solenoid] Tested Danfysik Quench Detection Units Reset

[Ruben Fair]

Thank you Pablo and Tyler. 

Yes - we have agreed that if we have a QD hard-wire trip - we will need to investigate and therefore it would not be correct to reset via EPICS. 

We shall remove it from the checklist. 

Regards 

Ruben

Hello Ruben, 



Yesterday; Brian, Tyler and I worked on testing the reset interlocks button (EPICS). We realized that it does not work to make the reset in REMOTE mode for the three Quench Detection Units, since this reset has to do with a setting on the control board. The control board faults configuration needs "RS & F" commands to fully clear remotely. At the moment the reset for them can be made only manually in LOCAL mode on the control board of the MPS. Brian thinks that this might be for safety reasons. 

So EPICS reset for quench detection interlocks should not have been in the checklist. 



Best Regards 

Pablo Campero
