- 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:
Fatal: Communication Failure
- ACQUITY Sample Manager (SM)
- Full loop injection in loadahead mode
- Firmware 1.50
- SCN918/SCN 918IVD
- SCN 855
- Known issue with firmware version 1.50 (although not all systems display this behavior).
- Other SCNs may have the same issue.
- 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
- 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.
