7-6 Fresenius Medical Care 4008 S (Version V10) SM-EN 7/01.13
7.1.6 Air detector test
F03 Venous With detuning in positive direction, the achieved change in the venous display is
less than 100 mmHg (7 seconds).
– The test detuning is defective (PV_DET, X632/C18)  X351/2
– Acknowledgement (P_VEN, X351/4)  X633L/B5, the change in voltage is
too low
– P-venous has not been calibrated
F04 Venous The deviation in the measured value between CPU1 and CPU2 is higher than
±12 mmHg (if P
ven
> 100 mmHg).
– Acknowledgement (P_VEN, X351/4)  X633L/B5 and X632/C17 measure
different voltage values
– P-venous has not been calibrated
F95 Venous System error
Error message Description
F01 Air Detector CPU1 interprets the air detector signal in a different way than does CPU2.
– Acknowledgements (LDA1, X351/14)  X632/C13 and X633L/C10

– Acknowledgement (LDA2, X351/6)  X632/C14 not 24 V
F08 Air Detector Closing of the air detector clamp via the CPU1 control line was not possible, or
CPU2 acknowledgement is incorrect.
– Clamp control (CLP_CTL, X634/C14)  X351/8 not 0 V.
– Acknowledgement (LDA2, X351/6)  X632/C14 not 0 V
