The system pressure is below the low pressure limit.
If the system pressure falls below the minimum pressure limit for 0.5 second,
Chromeleon stops the pump and this error message is displayed. The
minimum pressure limit can be set to between 0 and 33.7 MPa (0 and
4900 psi) in the Chromeleon Instrument Configuration Manager.
To troubleshoot:
1. Make sure the eluent bottle is full.
2. Check for liquid leaks (see
3. Prime the pump (see
4. Click the pump On button on the Chromeleon ePanel.
For additional troubleshooting information related to pump priming, see

The system pressure has exceeded the high pressure limit.
If the system pressure exceeds the maximum pressure limit for 0.5 second,
Chromeleon stops the pump and this error message is displayed. The
maximum pressure limit can be set to between 0.7 and 34.4 MPa (100 and
5000 psi) in the Chromeleon Instrument Configuration Manager.
To troubleshoot:
1. Check for blockages in the liquid lines by working your way backward
from the cell to the pump (see
2. Click the pump On button on the Chromeleon ePanel.
