[Dsg-hallb_magnets] Solenoid interlocks sp. sht - update required / ERR slides

[Pablo Campero]

Hello Ruben, 
Please find my answers in blue. 

I see that the SST interlocks sp. sht has not yet been updated. Please ensure that this is completed today. 
This is primarily to do with the delay threshold for the VCL flow and any other changes you need to make. 
Please use the sp. sht. version update procedure that I shared with everyone last week. 

The spreadsheet Solenoid_DBX_PIDs_Interlock Thresholds_EM Forces 06_08_2017 was updated. The following were the changes: 
1. Under the SST Interlock sheet, it was modified: 
1.1 The delay threshold for the VCL Flow was changed from 500 [ms] to 4 [s] 
1.2 Added three new columns with the EPICS names indicators for each interlock. 
2. Under the Var_calcs and Intloc TH sheet: 
2.1 I added some comments and pointed with a red circle the discrepancies that I found in the signal names and formulas used to the calculations. 
2.2 Added PVArray position of the cryogenic signals that are calculated on the DBX PLC (See the first column on the sheet). 
2.3 Added PVArray position for HE_CP_CD_DT cooldown signal. 
2.4. Verified that all calculations in this sheet now are matching with the Solenoid PLC and DBX codes. 



By the way, have you now updated your ERR slides to take into account the comments from the dry run and to ensure it matches with Dave's presentation and cool down procedure? 
I'm currently correcting my presentation based on the observations, most of the correction were done but in order to completed all the corrections I need to clarify: 
1. The comments that I pointed on the Var_calcs and Intloc TH sheet mentioned above. This is about of the correct threshold for the signal CM_DT_MAX. 
2.We need to finished the Solenoid Cooldown Parameters screen to update my slide 9. 

Best Regards, 
Pablo
