The following features help you to identify and eliminate the source for
problems that may arise during operation of the device.
TIP For information about operating issues that might occur during the
operation of a Vanquish system, refer to the Vanquish System Operating
Manual.
If you are unable to resolve a problem following the instructions given
here or if you experience problems that are not covered in this section,
contact Thermo Fisher Scientific Technical Support for assistance. See
the contact information at the beginning of this manual.
To facilitate device identification, have the serial number and technical

The status indicator LED bar on the front side of the device and the
STATUS LED on the keypad inside provide quick visual feedback on the
operational status of the device. If the device firmware detects a
problem, the status indicators are red.
Leaks are a potential safety issue. Therefore, if a leak sensor detects
leakage, beeping starts to alert you in addition to the message in the
Instrument Audit Trail and the status indicators changing to red. Follow
the instructions in this manual to find and eliminate the source for the
leakage.
If the device firmware detects a problem, the problem is reported to the
chromatography data system.
The chromatography data system logs information about all events
related to instrument operation for the current day in an Instrument
Audit Trail. The Instrument Audit Trail is named with the current date,
using the format yyyymmdd. For example, the Instrument Audit Trail for
May 15, 2023, is named 20230515.
The Instrument Audit Trails can be found on the ePanel Set (Audit
ePanel). In addition, Audit Trails for each instrument are available in the
Chromeleon 7 Console Data view, in the folder of the instrument.
Messages in the Instrument Audit Trail may be preceded by an icon. The
icon identifies the seriousness of the problem. For possible causes and
remedial actions, see Messages (} page 158).
