This error occurs if the driver current is above the allowed value.
To troubleshoot:
1. Turn off the pump flow.
2. Turn off the SP power briefly by pressing the SP power switch.
3. Turn on the SP power again and restart the pump flow.
4. If the problem persists, contact Technical Support for Dionex products for
assistance.
This error occurs if the loading 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 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.
