Missing Vial or Missing Wash Vial
No vial was found in the position defined in the method or sequence.
When the needle carrier moves to a vial and the needle goes into the vial, the
position of the needle is monitored by an encoder behind the vial pusher. If no
vial is present, the encoder detects an error and the message “missing vial” is
generated.
Probable Causes
• No vial in the position defined in the method or sequence.
• Defective needle carrier assembly.
• Defective transport assembly flex board.
• Defective MTP board.
Suggested Actions
✔ Install the sample vial in the correct position, or edit the method or
sequence accordingly.
✔ Exchange the needle carrier assembly.
✔ Exchange the sample transport assembly.
✔ Exchange the MTP main board.
