  7. LAT Environmental Test Planning and Design Review 3-4 May 2005 Cable Layouts Rich Bielawski

  8. High Bay Cable Layout

  9. Cable Layout - High Bay Operations (1/2) • Configuration • EGSE may be located inside clean tent if there is room otherwise it will be located just outside the clean tent • All are point-to-point cables from LAT connector saver to EGSE • No unregulated power cables • Thermostatically controlled survival heaters will not activate at ambient temperatures • Unique Cable Requirements • Design cables so that same cable set can be used in Dynamics and EMI testing • Interfaces • SC-LAT interface connectors are per the SC-LAT ICD • JL-39 and JL-69 (test ports) are per LAT-DS-02139 • BPU interface is per the SC-LAT ICD • VSC, external test point interface, external crate interfaces are SCSI except for the 1553 interface which is per the SC-LAT ICD

  10. Cable Layout - High Bay Operations (2/2) • Statistics • Cable Count: 26 • Drawings Required: 11 • Taking advantage of similar cable designs • Near-Term Tasks • Create wirelist • Determine cable lengths as these cables will also be used in other test phases • Begin cable drawings • Procure cable parts i.e. wire, connectors, backshells, etc

  11. Vibration Test – LAT LPT Cable Layout

  12. Vibration Test – Accel Cable Layout

  13. Cable Layout - Vibration Testing (1/2) • Configuration • LAT EGSE and test cables are located inside vibe room • During the actual vibe test, all LAT EGSE cables are demated except for connector savers and accel cables. • LAT is cabled up for LPT’s, i.e. between vibe axes. • Uses same cables as High Bay Ops. • Unique Cable Requirements • None

  14. Cable Layout - Vibration Testing (2/2) • Interfaces • Accels • NRL accel boom interface is BNC • EMI shield interface defined in LAT-DS-02139 • Accel cable connectors are defined • Adaptors are needed in some cases • LAT EGSE test cables • See High Bay Ops slide • Statistics • Accels cables • Cable count: 37 • Drawings required: 0 (cables are purchased off-the-shelf) • LAT EGSE test cables • See High Bay Ops slide • Near-Term Tasks • Accel cables • Most cables have been procured already • Need to verify quantity • Need to procure interface adaptors • LAT test cables • Same as in High Bay Ops slide

  15. Acoustic Test - LAT LPT Cable Layout

  16. Acoustic Test - Accel Cable Layout

  17. Cable Layout – Acoustic (1/2) • Configuration • LAT EGSE and test cables are located just outside of main chamber door. • During the actual acoustic test, all LAT test cables are demated except for connector savers and accel cables. • LAT is cabled up for LPT’s, i.e. pre- and post-test. • Main chamber door is opened and test cables are routed through doorway to the LAT • Use same cables as High Bay Ops • Unique Cable Requirements • None

  18. Cable Layout – Acoustic (2/2) • Interfaces • Same interfaces as in Vibration Testing slide • Statistics • Accels cables • Cable count: 47 • Drawings required: 0 (cables are purchased off-the-shelf) • LAT test cables • See High Bay Ops slide • Near-Term Tasks • Same as in Vibration Testing slide • Accel cables • Most cables have been procured already • Need to verify quantity • Need to procure interface adaptors • LAT test cables • Same as in High Bay Ops slide

  19. EMI Radiated – LAT Cable Layout

  20. Cable Layout – EMI (Radiated) • Configuration • LAT EGSE located in control room • LAT cables mated during test • Cables fed through opening in chamber wall • Uses same cables as High Bay Ops • Unique Cable Requirements • EMI shielded cables and connector savers are required. • Interfaces • Same interfaces as in High Bay Ops slide • Statistics • Same status as in High Bay Ops slide • Near-Term Tasks • Same status as in High Bay Ops slide

  21. EMI Conducted – LAT Cable Layout

  22. DAQ Feed Terminal Block (TB 1& 2)

  23. SIU Feed Terminal Block (TB 3 & 4)

  24. Cable Layout – EMI (Conducted) • Configuration • LAT EGSE located in control room • LAT cables mated during test • Cables fed through opening in chamber wall • Uses same cables as High Bay Ops except for DAQ and SIU power cables • Unique Cable Requirements • EMI shielded cables and connector savers are required • Need to break-out power leads for DAQ and SIU feeds • Interfaces • Same interfaces as in High Bay Ops slide except for the DAQ and SIU power cables • DAQ and SIU power cables have an additional intermediate interface to terminal blocks • Statistics • Cables required: 22 high bay cables + 8 breakout power cables • Cable drawings required: 4 • Only for unique power cables • Taking advantage of similar cables • Near-Term Tasks • Work out details of the terminal block interface • Begin cable drawings • Procure cable and terminal block interface parts

  25. LAT TVAC Electrical Layout

  26. Cable Layout – TVAC (1/3) • Configuration • EGSE is located near port plates used by LAT • Cables are P2P or breakout into two connectors • Includes unregulated feed cables • Unique Cable Requirements • Inside chamber cables and connector savers must be TVAC compatible • Inside chamber cables must be baked out prior to LAT TVAC

  27. Cable Layout – TVAC (2/3) • Interfaces • LAT interface • SC-LAT interface connectors are per the SC-LAT ICD • JL-39, JL-69, JL-264, JL-266 (test ports) are per LAT-DS-02139 • ACD flyaway thermistor connector is TBD • TC terminal block interface is TBD • Chamber interface • Copper paths • Feed thru’s: Glenair 257-135-24-61 (61-pin circular) • Mating connector on cables: Amphenol MS3475L2461S • Thermocouples • Feed thru’s: Deutsch DM5623-37-37PP (37-pin circular) • Mating connector on cables • Deutsch 13084-37S-5020 (inside chamber) • Deutsch DS07-37S-081 (outside chamber) • BPU interface is per the SC-LAT ICD • VSC, external test point interface, external crate interfaces are SCSI except for the 1553 interface which is per the SC-LAT ICD • NRL Thermal Data Acquisition System interface is defined • NRL is responsible for the thermocouple cables

  28. Cable Layout – TVAC (3/3) • Statistics • Cable count: 72 • Drawings required: 36 • Taking advantage of similar cables • Near-Term Tasks • Finalize GSE heater power requirements • Procure long-lead items ASAP, i.e. chamber feed thru’s • Close loop with ACD thermistor interface and terminal block interface • Create wirelist • Determine cable lengths • Begin cable drawings • Procure cable parts i.e. wire, connectors, backshells, etc
