Transport Assembly
This troubleshooting guide is meant to help you diagnose and repair
autosampler problems.
In general, autosampler problems can be divided into three categories.
1 Intermittent lock-ups with or without vial in the gripper fingers
with error messages
❏ motor overtemp (0 or 1 or 2 or 3)
❏ movement failed (0 or 1 or 2 or 3)
❏ missing vial
Many times the sampler is being used very heavily.
2 Jittery (shaky) movement in X and/or theta axes and/or when the
needle goes through the gripper arm into the vial with error
messages
❏ motor overtemp (0 or 2)
❏ movement failed (0 or 2)
3 Poor alignment, seen during vial pickup and vial replacement
and/or when the needle hits the gripper arm with error messages
❏ motor overtemp (0 or 2 or 3)
❏ movement failed (0 or 2 or 3)
❏ missing vial
NOTE Motor 0=X; 1=Z; 2=Theta; 3=Gripper.
