Standalone Control
Running the samples

the waste into both waste positions. During one run, it dispenses all of the
waste into one position. During the next run, it dispenses all of the waste
into the other position.
If a tray is not installed, the injector takes all the washes from the solvent
A bottle and expels the waste into the waste A bottle.
8. If a tray is installed, the tray returns the vial to its original position in the
tray quadrant.
9. The automatic liquid sampler returns all its moving parts to their idle
positions.
10. The injector waits until the GC sends a ready signal to continue.
Steps 3 through 8 are repeated according to the “injections per sample vial” set
with the control switches and are repeated until the tray cannot find another
vial or until the injector completes the last vial.
11. The controller gives a single beep to indicate end of sequence.
Stopping or interrupting a run or sequence
The following events interrupt a run:
• The power to the controller fails.
• You press the stop button.
• The sampler recognizes a safety or operator fault, such as:
– You open the syringe access door.
– The tray gripper drops a sample vial.
– The syringe needle hits the metal side of the crimp cap.
– The plunger binds.
With standalone control, the sampler stops immediately and aborts any
sequence. If the interruption occurs after the sample is injected into the GC,
the GC and the data collecting device do not complete the sample-in-progress.
If the interruption was caused by a problem that the sampler recognizes, it
provides you with some feedback by a combination of flashing LED indicators.
