General Error Messages
Synchronization Lost
During an analysis, the internal synchronization or communication between
one or more of the modules in the system has failed.
The system processors continually monitor the system configuration. If one or
more of the modules is no longer recognized as being connected to the system,
the error message is generated.
Leak
A leak was detected in the module.
The signals from the two temperature sensors (leak sensor and
board-mounted temperature-compensation sensor) are used by the leak
algorithm to determine whether a leak is present. When a leak occurs, the leak
sensor is cooled by the solvent. This changes the resistance of the leak sensor
which is sensed by the leak-sensor circuit on the main board.
Probable cause Suggested actions
1 CAN cable disconnected.
• Ensure all the CAN cables are connected
correctly.
• Ensure all CAN cables are installed correctly.
2 Defective CAN cable.
Exchange the CAN cable.
3 Defective main board in another module.
Switch off the system. Restart the system, and
determine which module or modules are not
recognized by the system.
Probable cause Suggested actions
1 Loose fittings.
Ensure all fittings are tight.
2 Broken capillary.
Exchange defective capillaries.
3 Loose or leaking purge valve, inlet valve, or
outlet valve.
Ensure pump components are seated correctly.
If there are still signs of a leak, exchange the
appropriate seal (purge valve, inlet valve, outlet
valve).
4 Defective pump seals.
Exchange the pump seals.
