Dionex VP Vacuum Pump Installation
14 Doc. 065186-02 1/12
For a Dionex ICS-3000 DP/SP:
a. Highlight relay 2 or 4 on the TTLs/Relays/AC tab page. If the
pump is a Dionex DP, assign relay 2 to the top pump and relay 4
to the bottom pump in the module.
b. Press the F2 key to display the Device Configuration dialog box.
c. In the drop-down box, select Flow Zero as the Function for the
selected relay. This ensures that the Dionex VP is automatically
turned off whenever the chromatography pump is turned off or
the flow rate is set to zero.
NOTE The Flow Zero function is not available unless
Dionex DP/SP Moduleware version 2.75 (or
later) is installed.
d. Click OK.
If the Dionex VP continues to draw a vacuum when the
chromatography pump is not pumping liquid, the consumable or
accessory may be damaged. For example, the vacuum may destroy
the membrane inside the Dionex CRD.
