This error occurs only when the cap on the seal wash reservoir is equipped
with a drop sensor and the sensor is very dirty.
To troubleshoot:
1. Clean the sensor electrodes with water or solvent.
2. If the message appears again, the leak sensor may be defective. Contact
Dionex for assistance.
This error occurs if you attempt to change a parameter that users are not
allowed to adjust.
To troubleshoot:
Only Dionex Service Representatives can change this parameter.
This error occurs if the upper pressure limit specified in the program is
exceeded. The running batch is aborted (default) and this message appears.
To troubleshoot:
1. Check all tubing connections for signs of blockage; replace as needed (see
Section 9.1
).
2. As columns age, their backpressure increases. It may be necessary to
compensate for this by increasing the high pressure limit. If the column is
the source of the high backpressure, clean the column. (Refer to the
column manual provided on the Dionex Reference Library CD-ROM
(P/N 053891) for instructions.) If this does not eliminate the problem,
replace the column.
3. Observe a run to see whether the high pressure limit is triggered when
injection occurs; if it is, the injection valve may be the source of the
The rear-seal leak sensor is malfunctioning.
This function cannot be adjusted by the user.
Upper pressure limit exceeded.
