Error Message Remedial Action
Pressure sensor malfunction The pressure transducer for the system pressure reported a pressure
under 0 MPa.
Verify that the cable for the system pressure transducer is properly
connected to the P-Sys connector on the interior front panel.
Purge pressure limit
exceeded. After you have initiated purging in Chromeleon (Purge property set
to On), a pressure of more than 5 MPa built up.
Open the purge valve if it is not yet open. If you are operating an
ISO-3100BM, observe the precautions on page 90.
Check the flow path for indications of blockage (also, see "Upper
pressure limit exceeded").
Quiescent current too large The motor current is too high when the pump is stopping. Turn the
pump off and on again by pressing the power switch on the rear of
the pump.
Self test failed: xx (where xx = additional text)
This message usually appears together with another message
indicating which failure occurred during the self test. Refer to this
message for recommended remedial actions.
Solvent rack leak detected. The leak sensor in the Solvent Rack has reported a leak.
The degasser may not be connected properly to the pump. Verify that
the Solvent Rack is properly connected to the pump.
There is a leak in the system or a fluid connection is loose. Find and
eliminate the source for the leak. Tighten leaking connections and dry
the leak sensor (

Operating Instructions for the Solvent Rack ).
The cam position is yet
unknown. It is necessary to
run at least 2 revolutions. The position of the cam is unknown after the piston has been
replaced. Turn on the flow and have the pump run for two
revolutions to establish the position.
The piston seal leakage has
exceeded the recommended
limit.
Inspect the piston seals for leakage (

page 134).
Consider replacing the piston seals (

page 135).
The pressure exceeded the
absolute limit. The pressure has exceeded the absolute pressure limit. This message
appears when pressure builds up extremely fast.
This may happen, for example
- When the pump delivers at a high flow rate while the pump outlet is
closed with a fitting plug.
- If a pump with a low-volume mixing system (mixing volume

200
µL) delivers at a high volume rate and the valve in the autosampler
switches from Load to Inject or vice versa.
Take appropriate remedial action and retry
The pressure signals are not
consistent. Air may be
trapped in the working
cylinder. The error can be due to large amounts of air in the pump heads, for
example, during initial installation.
Verify that the pressure transducer cable of the pump head is properly
connected to the P-Work connector on the interior front panel.
Purge the pump heads thoroughly (

page 54). Perform a self test if
necessary.
