[dsg-hallb_svt] CVT work

[Brian Eng]

Work on bringing the RICH N2 cRIO back online took longer than anticipated so I didn't get a chance to repair the broken wire yet.

I'll try and do that Monday night.

The V450 crate is still upside down, but I'm not sure that matters.

Is the switch that is in that picture one that can be used for the SVT or is that only for MM?

I will go in tonight to finish connecting the cooling signals, the humidity ones are there, but will need connection from the actual HTSBs.

As for running the interlock program from EEL/124 I was just using the Linux computer already there, you should be able to log into the clasrun account (if it wasn't already logged in from when I was there) and start clascss.

Hello Brian,


We are planning to mount the SVT on the support tube early next week. Once it is mounted, we will need help from DSG to connect and route the cable bundles and setup the SVT test bench. In parallel we are setting the BMT test stand. Here is the current location of the crates after the changes you suggested. Please let me know if you have comments. Thank you for your help.

Hi Yuri,

I've started connecting the hardware interlock chassis. I've verified that the chiller interlock works (both with the setpoint trips as well as the override key) as well as the MPOD ones.

I still have more work to do as I found some cables that were damaged and will need to be repaired.

Some quick comments.

  *   We need a switch installed near the racks. Right now I have a single network cable going to the cRIO but that should really be going to a switch
  *   The VME crate with the V450 cards is installed upside down, but even then it will have trouble reaching the patch panel
  *   So either the VME should be moved to the floor under the patch panel or another rack is needed

If there are any particular signals you'd like wired up when I come in tomorrow night let me know and I'll focus on those. Could you also check the interlock thresholds? It seems like some of them didn't get set correctly when moving things around.

I left the coolant pressure interlock enabled so that it would force everything to be off.
