Important information on the system Technician’s qualification Purpose
This Technical Manual is intended for service technicians and is to be used for first studies (to acquire a basic knowledge) and for reference purposes (for TSC, Maintenance and repair). The Technical Manual, however, does not replace the training courses offered by the manufacturer.
Requirements
Knowledge of the current Operating Instructions for the respective system. Background experience in mechanics, electrical and medical engineering.
Precautions for working on 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 this technical document require the availability of the necessary technical test equipment and accessories.
Specifications
For the specifications of the respective system, refer to the current Operating Instructions. Observe the information on the specifications.
Precautions
Before turning power on, repair any visible damage. Prior to opening the system and when working on the open system, the following precautions have to be observed: – Protect the components against ingress of fluids. – Do not touch live parts (e.g. connectors of the power cable or heater). – Disconnect and connect all jacks, connectors and components only when the system is turned off.
ESD precautions
When repairing the system and replacing spare parts, observe the applicable ESD precautions.
Hygienic measures
The system and the consumables are generally considered to be contaminated and must therefore be sufficiently disinfected by the responsible organization as specified by the manufacturer.

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

Water alarm
Water supply interrupted.
XXX not calibrated
A valid calibration value is missing in the NOVRAM.

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. LP 754 defective – IC5 on P.C.B. LP 632 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. LP 633 defective – P.C.B. LP 633 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. LP 754 defective – IC5 on P.C.B. LP 632 defective – During the test the lines are inserted on the corresponding pump using the Start/Stop key. – P.C.B. LP 633 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. LP 633 defective – P.C.B. LP 633 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. LP 633 defective.
