[Dsg-hallc_nps] [EXTERNAL] Re: NPS low voltage EPICS development tests?

[Tyler Lemon]

Hi Brad,

I've finished the LV EPICS tests for today.

I never got to the point in communicating to the MPOD since I apparently had some configurations set up incorrectly.

I'll schedule another time with you later on to try again.

Hi Brad,

Thank you for the information!

I'm planning on starting the tests at 9:00AM.

I'll let you know when I've finished and the outcome.

Hi Tyler,

The EEL/108 setup will be idle tomorrow, so that is a good time to run
some tests.

Right now there is only one LV cable plugged into the MPOD crate
(top-left location in the EEL/108 racks).  I turned the LV off for all
channels just now, so you are welcome to just unplug the cable from the
front panel and proceed with your tests.

NOTE: The channels are configured use use the sense lines for voltage
  regulation so you will likely have to toggle the setting to use the
  'internal sense' lines so it regulates against the terminal voltage
  or it will just throw errors with the cable unplugged.

I should be on-site after 10am tomorrow (Wed) and should be free to drop
by if you run into any hardware issues.  You can reach me via Teams or
on my cell 757-344-2494.
