[Dsg-hallb_magnets] Solenoid - Instrumentation Test

[Pablo Campero]

Hello Ruben, 

here is the answers to your questions: 

1. Yes, I talked with Scot and we agreed about the drawings that need to be update. 
With regards to the sensor that the Cryocon units are displaying i.e. "Internal_Temp" (Displays temperature value ~ 300 K) on its channel F, I noticed that it doesn't appears on the documentation (This channel on the cryocon unit according to the documentation should be spare), maybe Nick knows why this sensor was configured on the Cryocon units since he was who configured these. 

- Nick can you verify this sensors on Cryocon 1 and also there is another not assigned sensor on Cryocon 2 channel D, that is displaying ~ 300 [k] at the moment? 


2. The changes for the pressure transducers (PT) will be make on the scale factor of the PLC input module, I verified the PT that are already install in the SST and they have ranges of 0-75 psi (PT8620) and 0-50 psi (PT8670). drawing 0626 indicates 0- 150 psi, so it has to be updated. I will do those changes on the PLC but I need to go off line on the PLC to changes this parameters on the scale factor. 


3. That means that these instrumentation/sensor will be check later, probably before to perform the cooldown for the solenoid, that why we need to check with Dave to make sure that once we power on this instrumentation they won't be affected or damaged. 

4. The screen that is used to set and change the parameters of the PID control for the heaters at the moment are displaying HTR8120 (Torus heater) rather than HTR8620 and HTR8672(Solenoid Heaters). 

- Wesley- can you please take a look of these screens. 


5.These power level are just to be aware of the time that we can have the heaters ON without any coold fluid, but as I said this I consider that is better test this heaters after. 

6. Wesley has been working to update these screens. 



With Regards 
Pablo Campero

Pablo, Renuka 

Can you please clarify the following: 

1. In the comments column, you have stated that sensors do not appear on a drawing for example. How are you communicating to Scot that drawings need to be updated? 
I note that you have referred to the following drawing nos. 0678, 0626, 0640, 0623. 

2. You have also noted that scale factors for PTs need to be changed. Will you be making these changes and have they been made already? 

3. What does 'Check with Dave K mean'. Will you be checking with Dave and what needs to be checked? 

4. You have noted a required change to the EPICS screen - have you communicated this to Wesley? 

5. What the 'power levels' hat you need to check with Dave - for HT8621A and HT8621B? 

6. Have you communicated to Wesley what needs to be changed for the heaters on SST-Helium? 

Regards 

Ruben

Hello Renuka, 

Tyler, Amanda and I have been working to complete some of the tests to the instrumentation in the SST. 
I updated the Instrumentation TEST PLC- EPICS PLAN_v3_February 28th 2017 spreadsheet (attached). You can find there the comments and all the tasks that were checked. 

During the test we check again the wiring to make sure the correct functionality of the instrumentation and we found that the PV8674 (Pneumatic valve) was assigned to the wrong output PLC module. This signal was change from 1756-OF8 analog output module channel 0 to 1756-OW16I Relay output module channel 15, so the drawings 0623 and 0640 will be update by Scot, as we agreed. 

Please take a look and let me know if you have any comments. 

Best Regard, 
Pablo Campero
