Needle Movement Failed; Missing Vial - Agilent Technologies 1260 Infinity II User Manual

Needle Movement Failed

Error ID: 34213, 34214
The needle arm failed to move down into the needle seat.
The lower position of the needle arm is monitored by a position sensor on the
sampling unit flex board. The sensor detects the successful completion of the
needle movement to the needle seat position. If the needle fails to reach the
end point, or if the sensor fails to recognize the needle arm movement, the
error message is generated.

Missing Vial

Error ID: 34305
No vial was found in the position defined in the method or sequence.
When the gripper arm picks a vial out of the sample tray, the processor
monitors the gripper motor encoder. If a vial is present, the closing of the
gripper fingers is limited by the vial. However, if no vial is present, the gripper
fingers close too far. This is sensed by the processor (encoder position),
causing the error message to be generated.
