If the system pressure falls below the minimum pressure limit for 0.5 second,
Chromeleon or Chromeleon Xpress stops the pump and displays this error
message. The minimum pressure limit can be set to between 0 and 33.7 MPa
(0 and 4900 psi) in the Chromeleon Server Configuration Properties dialog
box or the Chromeleon or Chromeleon Xpress program.
To troubleshoot:
1. Make sure the eluent bottle is full.
2. Check for liquid leaks (see Section 4.2 ).
3. Prime the pump (see Section 3.6 ).
4. Restart the pump from the ICS-900 Control panel (see Section 3.6 ).
For additional troubleshooting information about pump priming, see
Section 4.3 .
If the system pressure exceeds the maximum pressure limit for 0.5 second,
Chromeleon or Chromeleon Xpress stops the pump and display this error
message. The maximum pressure limit can be set to between 0.7 and
34.4 MPa (100 and 5000 psi) in the Chromeleon or Chromeleon Xpress
Server Configuration or control program.
To troubleshoot:
1. Check for blockages in the liquid lines by working your way backward
from the cell to the pump (see Figure 2-4 for the flow schematic).
2. Restart the pump from the ICS-900 Control panel.
For additional troubleshooting information about system pressure, see
Section 4.7 .
The system pressure is below the low pressure limit.
The system pressure has exceeded the high pressure limit.
