Today I got a chance to check the AIP that was installed last week (here), unfortunately the pump was railed, and (2x)unfortunately we don't know when it railed, no data available for this ion pump yet (working on it, data is comming soon).

We have an old valve that appears to be faulty, to patch that problem I added another valve in-line until we get a replacement, I used the aux cart to pump down the annulus system for 3 hours during the maintenance period, but that amount of time was not enough to keep the controller from railing.  We left the aux cart pumping on the annulus system, and it will remain pumping until the controller can maintain the system without railing.

16:27 - aux cart is connected and turned on, and remains on.
20:18 - aux cart was set on top of shipping foam, 3 points for seismic isolation.

Location of the aux cart:
It is on the East side of BSC5, see photo.
