[Dsg-hallb_magnets] Hall B Solenoid - Additional TP for new relief valve

[Tyler Lemon]

Ruben, 

The other relief valves TPs are read by the Cryocons. 

There two open channels for the new TP: 
Cryocon unit 1, channel F 
Cryocon unit 2, channel D 

Once we know where the new TP will go, the PLC code can be updated. 

Regards, 
Tyler

All, 

Joe is having to put in an additional relief valve for the thermal shield. This valve will therefore require a TP (Platinum sensor) fitted to it just like the sensors planned for the other relief valves on the SST. The valve will be attached to the vacuum jacket of the SST and will therefore move with the SST. 

Once Joe has updated the P and ID with the sensor name, we will need to implement this. 

In preparation: 

Renuka, 

Can you identify a PT100 to use and pass it to Krister? 

Krister, 

Can you prepare the PT100 sensors (i.e. copper clamps and so on)? 

Scot, 

Can you prepare the cable (4 -wire x 100 ft will suffice) + label? 

Pablo, Tyler, 

Are the other TPs for the other relief valves being monitored by the LV chassis or by Cryocons? 
Either way, please start modifying the PLC code to accommodate this new sensor. 

Regards 

Ruben
