How to use the technical manual
Intended use This Technical Manual is intended for service technicians. It can be used both for
first studies (to acquire a basic knowledge) and for reference purposes (for TSC,
maintenance and repair). The study of this manual, however, does not replace
the training courses offered by the manufacturer.
Requirements Knowledge of the current Operating Instructions for the respective system.
Experience in mechanics, electrical and medical engineering.
Specifications For the specifications of the respective system, refer to the current Operating
Instructions.
Circuit diagrams and The identification on the PCB permits the user/technician to verify if the circuit
component layouts diagram/component layout matches the PCB actually installed in the system.
Explanation of the Note and Caution symbols used
☞Note
Informs the operator that in case of a failure to follow the steps as described, a
specific function will be executed incorrectly or will not be executed at all, or will
not produce the desired effect.
Caution
Advises the operator against certain procedures or actions that could cause
damage to the equipment or may have adverse effects on operators and
patients.

Instructions to be Observed when Servicing the System
Authorized persons Assembly, extensions, adjustments, modifications or repairs may only be carried
out by the manufacturer or persons authorized by him.
Test equipment The activities described in the Technical Manual require the availability of the
and accessories necessary technical test equipment and accessories.
Precautions When working on the open system, the following precautions must be respected:
– Protect the components against ingress of fluids.
– Do not touch live parts (e. g. connectors of the power cord or heater).
ESD precautions When repairing and when replacing spare parts, observe the applicable ESD
precautions (e.g. EN 100 015-1).

1.1.3 Description of the T1 test incl. error messages
●Notes on the descriptions of errors
The values specified are internal mathematical values, which are used in the program.
Resolutions and tolerances are as follows:
1. Arterial pressure: 3 mmHg/digit and ±1 digit of measured value.
2. Venous pressure: 3 mmHg/digit and ±1 digit of measured value.
3. Dialysate pressure, coarse: 6.0 mmHg/digit and ±1 digit of measured value.
fine: 0.5 mmHg/digit and ±1 digit of measured value.
4. CD resolution: 0.06 mS/digit and ±1 digit of measured value.
5. Temperature: 0.05 °C/digit and ±1 digit of measured value.
●Prerequisites for starting and running the test
Error message Description
Power failure Power failure while the test is in progress
Dialines not conn The dialysate lines are not in the interlock shunt.
Shunt Cover open The interlock shunt is open.
Connect Conc.Line
Wrong conc. supply The concentrate connector is in the rinse chamber, or concen-
trate is not connected at all. The error message depends on the
central delivery system preselected in the setup menu.
Blood Sensed by OD The optical detector senses blood in the system.
Flow alarm Line to or from the dialyzer kinked, malfunctions in the hydraul-
ics.
Water alarm Water supply interrupted.

Error message Description
F09 Bloodsystem 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.
F10 Bloodsystem 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.
F11 Bloodsystem 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.
F12 Bloodsystem 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.
F13 Bloodsystem 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 (BPSB_VEN, X348V/6) →X632/ B11, 12V
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).
