Description
Acknowledgement that CPU2 recognizes that the arterial blood pump
is inactive (BP not running).
– Acknowledgement (BPSB_ART, X348a/6) → X632/A11, 12 V miss-
ing.
– Control line (BPSST_ART, X634L/B14) → X348a/1, 12 V missing or
(BPST_ART, X634L/A14) → X348a/3, 12 V are missing.
Acknowledgement that CPU1 recognizes that the arterial blood pump
is inactive (BP not running).
– Acknowledgement (BPSB_ART, X348a/6) → X633L/A11, 12 V are
missing.
– Control line (BPSTT_ART, X634L/B14) → X348a/1, 12 V missing or
(BPST_ART, X634L/A14) → X348a/3, 12 V missing.
– Level is raised during the T1 test.
The arterial blood pump cannot be stopped by CPU1.
CPU2 recognizes that the arterial blood pump remains active.
– Control line (BPSST_ART, X634L/B14) → X348a/1, 0 V missing,
as well as (BPST_ART, X634L/A14) → X348a/3, 0 V missing.
– Acknowledgement (BPSB_ART, X348a/6) → X632/A11, 0 V are
missing.
– The level is raised during the T1 test, or the up/down key on the air
detector is blocked and the level is constantly raised.
The arterial blood pump cannot be stopped by CPU1.
CPU1 recognizes that the arterial blood pump remains active.
– Control line (BPSST_A, X634L/B14) → X348a/1, 0 V missing,
as well as (BPST_ART, X634L/A14) → X348a/3, 0 V missing.
– Acknowledgement (BPSB_ART, X348a/6) → X633L/A11, 0 V are
missing.
Applicable for SW 4.91/2.91 and higher if SN, ONLINE-HDF or
4008 HDF pump is connected (= ADKS active)
Acknowledgement that CPU2 detects that the pump is inactive (pump
is not running).
– Acknowledgement
missing
– Control line (BPSST_VEN, X634L/B15) → X348V/1, 12V missing or
(BPST_VEN, X634L/A15) → X348V/3, 12V missing
– Transistor T9 on P.C.B. LP754 defective
– IC5 on P.C.B. LP632 defective
– In 4008 HDF an HDF treatment was performed, followed by a
cleaning program with the substituate pump running, then the T1
test has been re-started.
The substituate pump must be switched off because otherwise the
test step will fail to be passed (problem was corrected with SW 3.20
in 4008 H/S systems: the substituate pump will be switched off
automatically on starting a cleaning program).
