Message and Code Possible Cause and Remedial Action
Code 4152 Pressure sensor
malfunction. Check cable
connection and retry. Verify that the cable of the pressure sensor for which the message appears is
properly plugged into the connection port. Restart the flow.
If the message appears again, the pressure sensor may be defective:
• If the message appears for the pressure sensor of a pump head, replace the
pump head.
•
If the message appears for the system pressure sensor, contact Technical
Support.
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
section 8.5.2,
page 211.
Code 4158 Out of eluent X. This message alerts you only if you are monitoring the solvent consumption
from Chromeleon (see
section 6.8, page 98 ). 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 (see
section 6.8, page 98 ). 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.
Code 4176 The 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 message appears again, follow these steps:
1. Purge the pump.
2. Perform pressure recalibration (see
section 8.5.3, page 213 ).
3. Start the pump flow.
If the message persists, the system pressure sensor may be defective. Contact
Technical Support.
Code 4182
Unexpected piston docking or
linear encoder error The message appears if the pistons are not correctly docked for pump
operation. Follow these steps:
1. With the SELECT button on the keypad, select both pump heads.
2. Undock the pistons by pressing the DOCK button.
3. Wait until undocking is complete (LEDs next to the FLOW button are flashing
green).
4. Dock the pistons by pressing the DOCK button again.
5. If the message appears again, contact Technical Support.
