Hello, 

The second interlock cRIO chassis has been installed in EEL 124. 

All interlock sensors that are not epoxied into RICH are read by this chassis. Any sensor placed into the electronic panel will be read by the second chassis. 

The labels on the cables and what sensors they read for the second interlock chassis are: 
Label on cable, T1, T2, H1, H2 
1, Temperature #1, Temperature #2, Humidity #1, Humidity #2 
2, Temperature #3, Temperature #4, Humidity #3, Humidity #4 
3, Temperature #5, Temperature #6, Humidity #5, Humidity #6 
4, Temperature #7, Temperature #8, Humidity #7, Humidity #8 
5, Temperature #9, Temperature #10, Humidity #9, Humidity #10 
6, Temperature #11, Temperature #12, Humidity #11, Humidity #12 
7, Temperature #13, Temperature #14, Humidity #13, Humidity #14 
8, Temperature #15, Temperature #16, Humidity #15, Humidity #16 

In the nitrogen panel cRIO, the temperature sensors connected correspond to the same numbering scheme as the humidity sensors. 

I was not able to add the calibration constants for any of the electronic panel humidity sensors. I will add them on Monday. 

To get the wiring for the relays that disable the CAEN, I had to remove the override switch's wiring as the ferrules were too large to accommodate the new wiring for the second cRIO. I will also rewire this on Monday. 

Best regards, 
Tyler
