6 Troubleshooting

6.1 General Notes

The AFC-3000 is both easy to operate and reliable. When the fraction collector does not
function properly, isolate the problem to determine if it originates in the Chromeleon
computer, the analytical instrument, the communications cable, or the fraction collector
itself. The following sections help you to identify and eliminate the source of problems that
may occur during the operation of the AFC-3000.
If you determine the problem is in the AFC-3000, check the power system, the
communications interface, or the diverter valve assembly to locate the cause of the problem
and resolve it.
If a problem occurs, always check the Chromeleon audit trail for messages (→ section 6.3).
If you cannot solve a problem using the steps given in this chapter, please contact Thermo
Fisher Scientific Service for Dionex HPLC Products.
