Dilution pump home sensor not detected
This error occurs if the dilution pump electronics fail to detect when the pump
reaches the home position. This 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
see Figure 3-14
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.
Dilution pump lost count
This is a warning message only. The pump continues to function and no action
is needed.
Dilution pump stopped or lost more than 20 steps
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
see Figure 3-14
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.
