12 Troubleshooting the
Rapid Sample
Introduction System
In the event that the ASXPRESS PLUS Rapid Sample Introduction System does not
function properly, isolate the problem to determine if it originates in the host
computer, the analytical instrument, or the ASX
PRESS PLUS Rapid Sample
Introduction System. If you determine the problem is in the ASX
PRESS PLUS
system, check the power system, communications interface, or software to find
the cause of the problem and resolve it.
This chapter explains how to troubleshoot ASX
PRESS PLUS Rapid Sample
Introduction System problems. If you cannot solve a problem using the steps
given in this chapter, you should contact CETAC Technologies Customer Service
and Support.
If the Valve/Pump Module Does Not Appear to be
Operating
1 Check that “Enable ASXpress Operation” is enabled in the Xpress Configuration
Tool.
2 Check for power system problems (See “Power System Problems” on page
129.)
3 Check for communication problems. (See “Communications Interface
Problems” on page 130.)
4 If you can manually control the valve, but when it does not operate when
sampling, check that the firmware personality is set correctly. (See
"Configuring the personality" on page 95.)
