PFN patch panel design Signals list:

  • Ross relay for EDS, Fire protection system, HV cable presence,

housing temperature, uswitches for doors and panels, fan power and controls, measurements of freewheel and dump diode,

  • ptical inks for IGBT triggers and status read back, HV divider for

IGBT,s and PFN signals.

BI.DIS

Cabling news

  • DEC, waiting for manpower to help identify all old cable to be removed from

BI.DIS system, with in mind keeping a few that the current BI.DIS

  • uses. Estimation of cables to be removed, approximatively 500.
  • DIC, on-going, I believe we have till end 2015 for finalizing the document,

however and in the meantime , an estimate of approximatively 200 cables (including inter-rack cables) has been made

  • DIR, the controls racks and positioning has been devised and sent to EN/EL
  • DIF, Optic fibers to be sent shortly for the optic fibers between racks and PFN’s

units.

Dummy load issues, HV cable detection

8 x 6 cables to encode (48) 6bit min (64) encoding, hence 6 digital channels per encoding scheme Means 288 channels, hence 9 DI32 modules This is complicated !!! Cable plate option for 8 cables ? 4 dig channels x 6 -> 1 DI module
