Hi Eric,

Tracking has the panels arriving on Friday. I’ll send an update when we have them in hand.

I just got the tracking number, however I don't think Fedex has picked it up yet. The vendor says it should get here tomorrow. I will send an update when I have info.

Hi Eric,

I just spoke with the vendor on the phone. Our order was lost in shipping. A new set of panels is finishing up today and should be sent out by tomorrow. Shipping usually takes just a few days with this vendor.

They will provide a tracking number once they have one and I will update the group.

Hi Brian,
You once asked me how to route the cables to the panel. Probir said that any route would be fine. There is no physical requirement. But ideally, we should use the existing cable trays because we will take pictures of the test. Are the cable ready for installation?

Hi Marc,
Did you find out the delivery date of the production panel?

Thanks a lot

Eric

Not as of this morning. Marc is trying to get the tracking number from the vendor so we can find out a delivery date.

Hi Brian,

Did you received the machined panels for the terminal block mounting for the production rack? If not, when might you get it?

Thanks

Eric

Hi Eric,

I’ve tested the two voltage comparators that will be used for TM3 testing and verified they are functional: upper/lower for each channel works and can reset the unit upon a fault.. Final balance/gain setup will need to be done once the voltage taps are wired up to the magnet and during powered testing. These VCs are on my desk in EEL/231 until we’re ready to mount them in the rack.

Mindy completed all the cables for the VTs and RTDs between TM3 and the I&C rack and they all have been tested successfully. All the cables are on the shelf as I don’t know what the cable routing will look like in the test lab. Has this been determined yet?

The machined panels for the terminal block mounting for the production rack are due to be shipped tomorrow. There currently aren’t enough terminal blocks in the small test lab rack for the full suite of sensors on a magnet hence needing the additional terminal blocks. Also the plan is to take the production panels over to the test lab so they only need to be assembled once, if we’re lucky we’ll be able to complete this by the end of the week, but depending on the shipping time this might not happen until early next week.

Thanks
Brian
