Doc. 031851-05 12/04 4-9
4.11 No DS5 Response
• DS5 not properly installed
Check that the DS5 is plugged into the component mounting panel and
screwed down until the bottom of the DS5 is flush against the sheet metal
panel (see Figure 2-3
and Figure 2-4).
• No flow from pump
Several conditions may cause this condition; see Section 4.4
and Section 4.5
for details.
• Cell electronics malfunctioning
Use the Chromeleon Wellness panel diagnostics to test the electronics with a
dummy cell (see Section 5.1
and the Chromeleon Help for instructions). If the
variance reading is outside the tolerance range (less than 1 µS), the electronics
are malfunctioning. Call Dionex for assistance.
4.12 High DS5 Output
• Background not suppressed by suppressor
If
Conductivity exceeds limit is displayed in the Chromeleon Audit Trail,
follow the instructions in Section 4.1
. Refer to the suppressor manual for
additional troubleshooting guidance. The suppressor manual is included on
the Dionex Reference Library CD-ROM (P/N 055405), located in the ICS-90
Ship Kit.
• Sample concentration too high
Dilute the sample (see Section 3.4.3
).
• Wrong eluent or regenerant
Check that you are using the correct eluent and regenerant for your system
(see Section 3.1
).
• Cell out of calibration
Recalibrate the cell from the Chromeleon Wellness panel (see Section 5.1
).
