This is a warning message only. The pump continues to function and no action
is needed.
This error can be caused by high pressure in the flow path.
To troubleshoot:
1. Check for a blockage in the pump outlet tubing or in the tubing
downstream from the pump (see Figure 3-11 for the SP1 flow schematic;
see Figure 3-14 for the SP2 flow schematic).
2. If no blockage is found, turn off the pump flow.
3. Turn off the SP power briefly by pressing the SP power switch.
4. Turn on the SP power again and restart the pump flow.
5. If the problem persists, contact Technical Support for Dionex products for
assistance.
The Mixer Stir Bar Auto-Recovery option in the Chromeleon 7 Instrument
Configuration Manager (see Section 3.5.2 ) uses Analog Input 4 to monitor the
mixer stir bar. If the stir bar is in an out-of-control state, the mixer motor is
stopped briefly and then restarted at a speed 5% slower than before the auto-
recovery occurred.
To troubleshoot:
This is a warning message only and no action is necessary.
Loading pump lost count
