Message and Code Description and Remedial Action
Code 4156 Compression limit reached. The compression value was 100% during the last stroke. If the
compression value is lower than 100% for several strokes
afterward, the message
"Compression back to normal" (code
4157) appears. If this message does not appear, inspect the flow
connections for indications of air bubbles. Purge the pump if
necessary.
If the message "Compression limit reached" persists, see
Checking the Compression Values ( } page 210) .
Code 4158 Out of eluent X This message alerts you only if you are monitoring the solvent
consumption from the Chromeleon software. The message
indicates for which solvent the reservoir is empty.
Code 4159 The waste bottle is full. This message alerts you only if you are monitoring the liquid level
in the waste container. Empty the waste container when needed.
Code 4161 Pressure recalibration
deviates by xx bar. The pump pressure has not been down to zero during the self-
test. Verify that the pressure sensor cable is properly connected
to the
P-SYS connector. Wait until the pressure is down and
repeat the test.
To speed up the pressure drop, open the purge valve and then,
start the self-test.
Code 4176 The pump pressure exceeded
the absolute limit. Check pressure sensor
cables for proper connection and flow
path for clogging. Then, perform a self-
test. Follow these steps:
1. Verify that the pressure sensor cables are properly connected.
Reconnect the cables if necessary.
2. Check the flow path for clogging and remedy the situation if
necessary.
3. Perform a self-test.
If the self-test is not successful, contact Technical Support.
Code 4234 The flow was stopped due to
a request from another module. The flow was stopped due to a request from another module.
The pump flow was stopped because of a problem with another
module. Check the Audit Trail for messages from other modules
and eliminate the source for the problem as appropriate.
Code 4237 Out of solvent. The solvent reservoir is empty.
Refill the solvent reservoir and purge the pump.
Code 4238 Mainboard initialization
failed. Main board initialization has not been successful.
1. This may be a temporary error. Turn off the module. Wait for 5
seconds and turn on the module again.
2. If the message appears again, update the firmware.
Code 4239 Could not build up enough
pressure. • Air bubbles may be trapped in the system. Purge the pump.
• Leakage may be present. As leakage usually occurs at a
connection, visually inspect all components and connections in
the flow path. For tests that can help you to identify the source
for the leakage, see
Testing the Pump for Leakage ( } page 208) .
Code 4240 Column temperature is too
high. The procedure that you want to perform will stop the pump flow.
This may damage the column if the column temperature is too
high. Reduce the column oven temperature. Repeat the
procedure.
