«Main Cause»
Solvent delivery was stopped because the pressure exceeded the system upper pressure limit value.
«Countermeasure»
Change the system upper pressure limit value ([System P.Max]) to an appropriate value or reduce the solvent delivery flowrate. If there are no setting problems, then inspect for flow channel blockage.
For example, in the case of LC-20AD (Maximum pressure: 40MPa) and SIL-20A (Maximum pressure: 20MPa) system, P.MAX of LC-20AD can be set to 30MPa, but if it exceeds 20MPa, [System P.Max] error will occur.
Check the [System P.Max] setting in the system controller configuration settings.
