If the system pressure falls below the low pressure limit, the pump stops and
this error message appears. 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. Make sure the eluent reservoir is full.
2. Check for liquid leaks (see Section 4.3 ).
3. Check that the waste valve is closed.
4. Prime the pump (see Section 5.16 ).
5. Restart the pump.
If the auxiliary valve fails to switch position within 1 second of being toggled,
the ICS-2100 Moduleware reports an error to Chromeleon and this error
message appears.
To troubleshoot:
1. If a sequence is being executed, terminate the sequence by selecting
Batch > Stop in Chromeleon.
2. Try to toggle the valve from position A to position B by clicking the
corresponding buttons on the ICS-2100 Control panel in Chromeleon (or
by clicking the Valve_2 commands under Pump_ECD in the Commands
dialog box).
3. Turn off the ICS-2100 power briefly and then restart.
4. If the problem persists, repeat Step 2 .
5. If the problem persists, contact Dionex for assistance.
