Operating Instructions
Remedial Action
(where x provides details on the hardware error)
Turn the module off and on again by pressing the power switch on
the rear of the module.
Repeat the solvent calibration of the ProFlow flow meter.
The humidity sensor reports an increased concentration of humidity
in the column chamber.
Eliminate the cause. Tighten leaking connection and vent the column
chamber.
(where xx is a number indicating the device. The number is important
for servicing.)
Turn the module off and on again by pressing the power switch on
the rear of the module.
The pressure values established during the self test are not plausible.
Turn the module off and on again by pressing the power switch on
the rear of the module. Contact Service if the message appears again.
Depending on the flow meter that is installed, proceed as follows:
ProFlow flow meter: Perform the Zero Balance Test (→ page 172)
and repeat the self test.
Classic flow meter: Run the Pressure Transducer Test
(→ page 172) and repeat the self test.
The pressure values established during the self test for the working
pressure of the left and/or right pump head of the NC pump are not
plausible.
The cable for the related pressure transducer may not be connected
properly. Verify that the cable properly connected.
If the message appears after you have installed a replacement pump
head, the head may not have been calibrated properly. Follow steps 8
a) through e) to install a replacement pump head (→ page 192) and
purge the flow meter (→ page 75).
