Part 2, Operation
7 Running Samples
Interrupting A Run Or Sequence
The following events interrupt a run:
• Power failures—The power to the GC or controlling device fails.
• Stop commands—[Stop] on the GC or 5890 ALS controller [Stop] is pressed,
or the Stop Run/Abort option is selected from the Agilent ChemStation.
• Safety or operator faults—The sampler recognizes these fault(s):
• The injector door was opened
• Turret error
• Plunger error
• Tray arm axis error
• The injector was moved on the GC during injection
• The tray failed to deliver a vial
Sampler response to interruptions
If the interruption was caused by a problem that the sampler recognizes, a
message appears on the 6890N, or 6850 GC or Agilent ChemStation. The 5890,
6890A, and 6890 Plus GCs do not display sampler messages. For more
information, see “Error Messages" on page 162.
• Power failure—Aborts the run. Restart the sequence (see below).
• Stop commands—Interrupts the run. Restart the sequence (see below).
• Safety or operator faults—Aborts the run. Restart the sequence (see below).
Pressing the stop button on the 5890 ALS controller aborts the sampler
sequence but does not stop the 5890 GC run. To abort the run you must use
the GC stop button.
Restarting an interrupted sequence
To restart an aborted sequence from the point of interruption:
1 Resolve the problem that caused the interruption.
2 Identify the last sample vial that was run successfully. (Check the vial
number of the last successful chromatogram.)
3 Assign the first sample vial run to be the vial number after the last
successful one.
