Operating Manual
Message and Code Description and Remedial Action
Code 92 Data verification failed. • This may be a temporary error. Turn off the module. Wait for 5
seconds and turn on the module again.
• The firmware may be defective. Update the firmware.
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 4098 Upper pressure limit
exceeded Check the flow path for blockage.
If the flow path is blocked:
• The column may be contaminated. Rinse or replace the column.
If the problem occurs due to column ageing, it may be sufficient
to increase the setting for the upper pressure limit.
• The autosampler may be blocked. Check the autosampler
components and eliminate the source for the blockage.
If the flow path is not blocked:
Test the static mixer for permeability (see Testing the Static Mixer
for Permeability ( } page 168) ).
Code 4099 Pressure fallen below lower
limit. Check the following causes:
• One or more solvent reservoirs are empty. Fill the reservoirs and
purge the pump. If you are monitoring the solvent consumption
from the Chromeleon software, the message "
Code 4158 Out of
eluent X " alerts you when a reservoir is empty.
• Air bubbles may be trapped in the solvent lines. Check the
solvent line filters. Purge the pump.
• Leakage may be present in the system. Resolve the leakage. For
the pump, see
Resolving Liquid Leaks (
}
page 209) . For the other
system modules, refer to the Operating Manuals for the
modules.
• A check valve may be contaminated or defective. Clean or
replace the check valves as appropriate (see
Check Valves
( } page 162) ).
• With the applied flow, the pump cannot build up enough
pressure to reach the lower pressure limit. Adapt the lower
pressure limit or increase the flow.
