Applicable for SW 4.91/2.91 and higher if SN, ONLINE-HDF or
4008 HDF pump is connected (= ADKS active)
Acknowledgement that CPU1 detects that the pump is inactive (pump
is not running).
– Acknowledgement (BPSB_VEN,X348V/6) → X633L/A13, 12V
missing
– Control line (BPSST_VEN, X634L/B15) → X348V/1 not 12V or
(BPST_VEN, X634L/A15) → X348V/3 not 12V
– IC16 on P.C.B. LP633 defective
– P.C.B. LP633 recognizes Single-Needle pump although it is not
connected.
Applicable for SW 4.91/2.91 and higher if SN, ONLINE-HDF or
4008 HDF pump is connected (= ADKS active)
CPU1 fails to stop the corresponding blood pump.
CPU2 detects that the pump remains active.
– Control line (BPSST_VEN, X634L/B15) → X348V/1, 0V missing as
well as (BPST_VEN, X634L/A15) → X348V/3 not 0V

Applicable for SW 4.91/2.91 and higher if SN, ONLINE-HDF or
4008 HDF pump is connected (= ADKS active)
Although the recognition of the venous blood pump (ADKS) is not
acknowledged, the 24-V supply voltage of the pump can be switched
off.
