1. PACS IQR Kick-off ESTEC, 13 Jan 2005 PA/QA Status1 O.H. Bauer MPE Garching PA/QA Status

2. PACS IQR Kick-off ESTEC, 13 Jan 2005 PA/QA Status2 Dr. W. Schmid started 01-Jan, replacing G. Igl Improved common understanding, but still not satisfactory ESTEC NCR system not really accepted WE: For QM/FM FMECA, WCA, HSIA, FDIR should improve as now under industrial contract CIDL/ABCL will be reworked according to agreed format Overall FM schedule with MIP/KIP still missing CIL has to be written Agreement on FM EIDP layout needed soon

3. PACS IQR Kick-off ESTEC, 13 Jan 2005 PA/QA Status3 PACS Status Warm Electronics –DPU  1553 I/F: Burst mode works with ILT EGSE, but not with CCS CDMU-DFE Under investigation  Telemetry packets corrupted after random time (checksum error): 1553-1355 interferences NCR: 19/11/04 –SPU  Compression ratio still too low Work in progress –DECMEC  Many problems (H/W and S/W): FPGA, SMCS-2 DECMEC back to CSL for final repair Very critical ! –BOLC  Problem with non-graceful switch-off Work in progress –WIH Ok!

4. PACS IQR Kick-off ESTEC, 13 Jan 2005 PA/QA Status4 PACS Status II FPU –Spectrometer Filterwheel  Could not be moved during cold ILT Problem found  Replaced by FM wheel, but without motor, in fixed position with ILT filter –Grating drive  Off-set of Zero position Solution for FM  Transformer box had to be added (at distribution board) to improve inductosync signal Solution for FM –Chopper  Envelope violation Solution for FM –Black Paint  Alodyne coating problem on two surfaces Paint removed from (paint peels off) several areas  No full qualification yet Critical !

5. PACS IQR Kick-off ESTEC, 13 Jan 2005 PA/QA Status5 PACS Status III S/C Interfaces –Problems with all three L0 flexible linksNRB needed –PACS requests short circuit connectors for all FPU connectors during all phases of cryo harness integrationAstrium to react EMC Test Results –PhFPU not compliant to RS-H requirementRe-open RfW-004 –DPU CE DM + Current Ripple on power lines non compliantNCR raised  RfW –SPU CE DM + Current Ripple on power lines non compliantNCR raised  RfW –ESD test not part of ILT  part of EQMProject to react
