Operating Manual
Description and Remedial Action
The firmware download has not been successful. Verify that the
correct firmware file was selected. Repeat the download.
The firmware is incomplete, for example, because the communication
between the chromatography data system and the module was
interrupted during the firmware download. Repeat the download.
Contact Thermo Fisher Scientific Technical Support for assistance. To
operate the device nevertheless, you can disable the leak sensor
functionality in the chromatography data system by setting Leak
Sensor Mode to Disabled.
You tried to download an incompatible firmware with an earlier
version number than the firmware that is currently installed in the
module. Downgrading the firmware may result in loss of functionality
or malfunctioning of the module. If required, repeat the download
with a firmware version later than the version currently installed in
the module.
The firmware may be defective or a firmware downgrade has been
performed.
Update the firmware to the current revision. See
Firmware (} page 141).
This is a software problem. The module produces data faster than the
computer on which the chromatography data system is running can
process the data.
1. In the chromatography data system, disconnect and reconnect the
module.
2. If this does not solve the problem, update the firmware or the
chromatography data system version.
3. If the problem persists: Also, third-party software on the computer,
for example, virus scanners or poor computer performance can cause
the problem. Contact the onsite IT department.
Communication with the module failed. The module did not respond
in time.
For the module for which the message appears:
1. Turn on the module if it is not yet turned on.
2. Check the system interlink connections to the module. Verify that
all system interlink cables are connected at both ends.
3. If the message persists, replace the system interlink cables.
All other modules on the system interlink bus are turned off or a
firmware download is performed on all other modules.
1. Check whether all other modules have been turned off or a
firmware download is performed on all other modules on the bus.
2. Wait until one of the modules on the bus is turned on or the
firmware download is complete.
3. A system interlink cable may be disconnected from the module or
is defective. Check the system interlink connections to the module.
Verify that all system interlink cables are connected at both ends.
4. If the message persists, replace the system interlink cables.
