Sychronization 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.
Probable Causes
• CAN cable disconnected.
• Defective CAN cable.
• Defective main board in another module.

Leak

A leak was detected in the detector.
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
VWM board.

Ensure the instrument showing the not-ready condition is installed correctly, and is
set up correctly for analysis.
Exchange the remote cable.
Check the instrument for defects (refer to the instrument's reference documentation).
Ensure all the CAN cables are connected correctly.
Switch off the system. Restart the system, and determine which module or modules
are not recognized by the system.
Ensure all CAN cables are installed correctly.
