Message and Code

Description and Remedial Action

Code 89 Liquid leak sensor missing or
defective.

Verify that the leak sensor is installed and the cable connector is
properly connected. Contact Thermo Fisher Scientific Technical
Support for assistance if the leak sensor is defective.

To operate the device nevertheless, you can disable the leak sensor
functionality in the Chromeleon software by setting

LeakSensorMode

Disabled

Code 90 Download firmware
mismatch – invalid version.

You tried to download a firmware with an earlier version number
than the firmware that is currently installed in the device.
Downgrading the firmware may result in loss of functionality or
malfunctioning of the device. If required, repeat the download with a
firmware version later than the version currently installed in the
device.

Code 103 Unexpected module
behavior – limited features available.

The firmware may be defective or a firmware downgrade has been
performed.

Update the firmware to the current revision. See

Code 118 USB Buffer Overflow.

This is a software problem. The module produces data faster than the
computer on which the Chromeleon software is running reads the
data.

1. In the Chromeleon software, disconnect and reconnect the
module.

2. If this does not solve the problem, update the firmware or the
Chromeleon software version.

3. If the problem persists: Also, third-party software on the computer,
for example, virus scanners, can cause the problem. Contact the
onsite IT department.

Code 120 The request timed out.

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 cables for proper connection.

Code 8013 No flow cell detected

Verify that the flow cell is properly installed. The lamp is
automatically turned off when a flow cell is missing.

Code 8032 Unexpected module
behavior. Flow cell

Code 8033 Unexpected module
behavior. Flow cell

If the message indicates "Flow cell": Verify that the flow cell is
properly installed. Open and close the doors. Turn off the detector.
Wait for 5 seconds and turn on the detector again. Replace the flow
cell and try again. If the message appears again, contact Technical
Support.

Code 8035 Signal overflow in
<channel name>

The reference signal is too low, or the PMT signal is too high. Check if
the flow cell is contaminated. Consider cleaning or replacing the flow
cell. Check if the sample concentration is too high, and make sure
that the excitation wavelength is set to a wavelength above the UV
cutoff wavelength of the eluent. The lamp may be too old and may
have to be replaced.

Code 8036 Reference signal too low
in <channel name>

The reference signal is too low (high absorption). Check if the flow
cell is contaminated. Consider cleaning or replacing the flow cell.
Check if the sample concentration is too high, and make sure that the
excitation wavelength is set to a wavelength above the UV cutoff
wavelength of the eluent. The lamp may be too old and may have to
be replaced.
