Released: March 2004 6850 Series II GC User Information page 87 of 256
Injector not aligned
Possible cause: Alignment procedure was not successfully completed
The turret in the 6850 automatic liquid sampler was changed or replaced, but
the alignment procedure was not performed.

Power to the injector was interrupted.
Possible causes: Injector cable (most likely)
Defective injector power supply
GC main board or AC board
The sequence is aborted when the injector resets.
Invalid sequence
Possible causes: Sequence is set up for wrong injection device
Hardware required by sequence is not installed and configured
GC configuration was changed during sequence execution
Defective cabling or connection
The sequence type does not match the current GC configuration. The
sequence loaded was set up for a valve or injector, and that valve or injector is
no longer present or is not configured.
No injector
Possible causes: Injector cable defective or not connected properly
Defective GC or injector board
After the run began, the GC could no longer detect the injector. Either the
injector cable is not securely connected to the GC or an electronics board
failed.
Plunger error
Possible causes: Syringe plunger is sticking
Defective plunger solenoid
Defective plunger carrier encoder
The injector tracks plunger motion. The error occurs if the injector determines
that the plunger is not moving as expected or if it cannot locate the plunger’s
position.

Possible cause: GC Not Ready. Check for Not Ready and other messages for the cause.
During an injection, the GC became Not Ready and the sampler halted. When
the GC did not become Ready within 10 minutes, the sampler reported an error
and the sequence aborted.
