Message and Code Possible Cause and Remedial Action
Code 4208 System pressure too
high. Please relief pressure and
retry. 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 persists, the system pressure sensor may be defective. Contact
Technical Support.
Code 4209 Could not build up
enough pressure. Please check
the fitting plug. The pump could not build up enough pressure during pressure sensor
calibration. This may be caused by the following:
•
Insufficient purging: Purge the pump.
•
Leakage at the pump outlet: Check that the plug at the pump outlet is properly
seated.
• Pump leakage: Test the pump for leakage (see section 7.12, page 178 ).
Code 4211 Invalid calibration.
Please perform pressure
recalibration. This message may appear while pressure recalibration is running, indicating that
the recalibration procedure cannot be performed correctly.
Check the pressure reading. If the pressure does not reach 140 MPa, follow
these steps:
1. Purge the pump.
2. Perform pressure recalibration (see
section 8.5.3, page 213 ).
If the message appears again, inspect the pump for indications of leakage and
replace leaky components as necessary.
Code 4212 Nonlinear pressure
sensor. Please perform pressure
recalibration. Start the pressure recalibration procedure (see section 8.5.3, page 213 ).
Code 4213 Head pressure does
not match system pressure
signal. Execute self-test or
perform pressure recalibration. First, run the self-test. If the message appears again, perform pressure
recalibration (see
section 8.5.3, page 213 ).
Code 4220 Pump head not
recognized. Please plug in the
sensor cable. If the pump head cable is not yet connected to the P-Work connector, connect
the cable. If the cable is connected, verify that it is properly seated. If the
problem persists, the pump head may be defective. Replace the pump head (see
section 7.7.2, page 138 ).
Code 4230 Wrong value
entered. Please verify your input
with the piston calibration data. The piston calibration value you entered is incorrect. Be sure that your input
corresponds to the 3-digit calibration value that is imprinted on the rear of the
piston. Check your input for typing errors.
Code 4231 Pressure sensor not
recognized. Please plug in the
sensor cable. 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 (see
section 7.7.2, page 138 ).
• If the message appears for the system pressure sensor, the system pressure
sensor may be defective. Contact Technical Service.
