Sample Manager crashing last injection when using load ahead with error: Fatal: Communication Failure - WKB11205

Article number: 11205

SYMPTOMS

  • Sample Manager crashing in the last line of the sample list when using load ahead (full loop)
  • Last sample of the sample list is drawn but not injected
  • System then shows a pop-up error message:
    Inlet Method
    Fatal: Communication Failure

ENVIRONMENT

  • ACQUITY Sample Manager (SM)
  • Full loop injection in loadahead mode
  • Firmware 1.50
  • SCN918/SCN 918IVD
  • SCN 855

CAUSE

  1. Known issue with firmware version 1.50 (although not all systems display this behavior).
  2. Other SCNs may have the same issue.
  3. Note: the loop should be offline, but will show the same error if online.

FIX or WORKAROUND

  • Upgrade the Sample Manager Firmware to v1.51

ADDITIONAL INFORMATION

  • If a work-around is needed (for example, before firmware upgrade can be performed):
    Use a blank/sacrificial vial as the last line of the sample list. Then the system fails on this rather than a required sample.
