Left-hand pump block carryover pressure is too high.
-or-
Right-hand pump block carryover pressure is too high.
This error occurs if the pressure in the primary pump head exceeds the
maximum allowed. (“Right-hand” refers to the bottom pump; “left-hand”
refers to the top pump in a dual-pump module.)
To troubleshoot:
1. Make sure that the tubing between the pump heads and the tubing leading
to the priming/outlet block is not plugged or blocked. Replace tubing
connections as needed (see
Section 9.3 ). Be careful not to overtighten
fittings.
2. Inspect the outlet check valve for blockage. Replace the check valve
cartridge if needed (see Section 9.6 ).
Motor malfunction.
This error occurs if an internal error in the pump drive mechanism occurs.
To troubleshoot:
Turn off the DP/SP power for 30 seconds, and then turn on the power again. If
the error message appears again, contact Technical Support for Dionex
products for assistance.
Motor position error. The motor is overloaded.
This error occurs if the pump motor is overloaded.
To troubleshoot:
1. One or more tubing connections may be plugged or blocked. Check all
tubing connections and replace as needed (see Section 9.3 ). Be careful not
to overtighten fittings.
2. If the “Upper pressure limit exceeded message” is also displayed, refer to
page 234 for additional troubleshooting steps.
