ICS-2100 Ion Chromatography System
82 Doc. 065291-01 3/09
This error indicates a problem in the pump controller electronics.
To troubleshoot:
Contact Dionex for assistance. The ICS-2100 electronics components cannot
be serviced by the user.
If the system pressure exceeds the set limit for at least 0.5 second, this error
message appears and the pump stops. Pressure limits can be set in the
Chromeleon Server Configuration or in the control program. The limits can
also be set on the touch screen
PUMP page (see Section B.7.1).
To troubleshoot:
1. Check for blockages in the liquid lines by working your way backward
from the cell to the pump. See Section 2.2
for the system flow schematics.
2. Check that the flow rate is set to the correct value.
3. Check that the high pressure limit is set to the correct value.
4. Restart the pump.
This error occurs if the ICS-2100 loses communication with Chromeleon.
To troubleshoot:
Verify that the USB cable is connected correctly from the ICS-2100 rear panel
to the Chromeleon PC.
