I am reviewing the labeling scheme you sent so we can know how we are going to carry the names to the cRIO input channels and in the software. I see the heater control thermocouples are mapped to the supermodules, starting in the low right corner and working
from right to left and then up to the next row on the right.</div>

The aluminum channels look like all zones have an AL1 and and AL2 starting at the low right, and going straight up and around, ending at the very bottom. But each aluminum heater is not uniquely named.</div>

You have enough cable to make 25, 100' lengths. The 25<sup>th</sup> cable will be needed for the Omega thermocouples.</div>

The controls rack side does not need to be terminated, but they will need to be stripped back for insertion into the thermocouple terminal blocks. So your plan sounds good. We may need to have further discussion on the labels to ensure everything maps well.</div>

Hi Marc,</div>
<div class="x_elementToProof" style="font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
I think I will get some of the students started on making thermocouple cables. I am proposing 24 cables for a total of 192 channels. Because we don't have an exact length, I am planning to tell them to make the cables 100' long. The ECal end will be terminated
with standard thermocouple connectors and the other end will be left unterminated. Since you don't require any connectors on your end, if you find that the 100' is too long to manage during installation, you can easily cut the cables shorter at that time.</div>
<div class="x_elementToProof" style="font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Does this sound good to you?</div>
