Metering Home Failed; Missing Vial - Agilent Technologies 1220 Infinity II LC User Manual

Metering Home Failed

Error ID: 4054, 4704
The metering piston has failed to move back to the home position.
The home position sensor on the sampling unit flex board monitors the home
position of the piston. If the piston fails to move to the home position, or if the
sensor fails to recognize the piston position, the error message is generated.

Missing Vial

Error ID: 4019, 4034, 4541, 4706
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.
