Dionex Sample and Fraction Manager
Sample and Fraction Manager: Troubleshooting

The following problems may occur during operation of the Sample and Fraction Manager:

Missing vial:

If no vial is present at the position from which the Sample and Fraction Manager performs injection, the batch is aborted. The Sample and Fraction Manager may then remain in an inconsistent state.

Therefore, Dionex recommends performing a Home command. If the tray in which the error occurred is part of a tray stack, you have to close the stack drawer manually.

Z collision error:

If the syringe holder collides with another component of the Sample and Fraction Manager while moving in z direction (e.g., because of an incorrect configuration), the instrument reports a z collision error.

First, find and eliminate the cause of the z collision error. Then, perform a Home command to re-calibrate the motor in the x, y, and z directions. The driver cannot perform movement commands until the motor has been recalibrated.

 Tip:  

The Sample and Fraction Manager is not equipped with collision sensors for the x and y directions. Therefore, stop the batch immediately if you observe a collision in the x or y direction. Afterward, perform the same steps as described for a z collision error.
