[Dsg-hallb_magnets] Solenoid - Instrumentation Test

[Wesley Moore]

Pablo, others,

Strong recommendation… If asking for a status or someone to do something, be clear/concise about who is being asked.  I happened to read far enough into this email that was directed at Ruben, to see that I was referenced.  

This is a HUGE downside to constantly using a mailing list for everything.

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.

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.
