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 component layouts
The identification on the PCB permits the user/technician to verify if the circuit 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 and accessories
The activities described in the Technical Manual require the availability of the 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).

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: 2. Venous pressure: 3. Dialysate pressure, coarse: fine: 4. CD resolution: 5. Temperature:
3 mmHg/digit 3 mmHg/digit 6.0 mmHg/digit 0.5 mmHg/digit 0.06 mS/digit 0.05 °C/digit
and ± 1 digit of measured value. and ± 1 digit of measured value. and ± 1 digit of measured value. and ± 1 digit of measured value. and ± 1 digit of measured value. 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 concentrate 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 hydraulics.
Water alarm
Water supply interrupted.

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).

F14 Bloodsystem
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.
F15 Bloodsystem
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 – Acknowledgement (BPSB_VEN, X348V/6) → X632/B11, 0V missing – Transistor T9 on P.C.B. LP754 defective – IC5 on P.C.B. LP632 defective – During the test the lines are inserted on the corresponding pump using the Start/Stop key. – P.C.B. LP633 recognizes Single-Needle pump although it is not connected.
F16 Bloodsystem
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. CPU1 detects that the pump remains active. – Control line (BPSST_VEN, X634L/B15) → X348V/1 not 0V as well as (BPST_VEN, X634L/A15) → X348V/3 not 0V – Acknowledgement (BPSB_VEN, X348V/6) → X633L/A13 not 0V – IC16 on P.C.B. LP633 defective – P.C.B. LP633 recognizes Single-Needle pump although it is not connected.
F17 Bloodsystem
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. – Acknowledgement line (ADKS, X348V/7) → X633L/A10 not 12V – Acknowledgement (BPSB_VEN, X348V/6) → X633L/A13 not 12V – Acknowledgement (BPSB_VEN, X348V/6) → X632/B11 not 12V – Online-HDF has already been switched on during the T1 test. – IC16 on P.C.B. LP633 defective.
