  9. LBDS ArmingGeneral • Re-arm/check individually each subsystems. TSU re-arming will ne possible only once all subsystems are READY • Re-arm BETS: will be READY if real-time tracking is in RECORDING • Re-arm IPOC:will be READY if FAAS is in ACQUIRING state • Re-arm KICKER (MKD & MKB): will be READY if • All generators are ON • Feedback Tracking stage is OK • Internal post operational check stage is OK • Check LASS: will be READY if machine is closed (no re-arm) • Check Re-trigger: will be READY if both re-trigger lines are closed and connection to TSU OK (no re-arm) • Re-arm and Lock TSU • All TSU inputs OK • Locked on revolution frequency

  10. LBDS ArmingSequencing 1. Individual sub-systems re-arming 2. Set Injection Permit to FALSE 3. Mask LBDS Ready to TRUE for 500ms 4. Wait for Beam Permit TRUE from BIS 5. Re-arm & lock TSU 6. Release LBDS Ready Mask 7. Set Injection Permit to TRUE
