– 24 V: > 26 V / < 22.5 V.
– 12 V: > 13.5 to 15 V / < 10.5 V.
– Check the power supply unit.
– Power supply unit okay: Check the voltages applied to P.C.B. LP 633:
– +12 V: X633R/A, C31.
– +24 V: 24V_EM: X633L/B20.
24 V Switched Off
– The 24-V supply voltage has fallen below 5 V.
– The machine enters the safe state and must be switched off/on.
– Check the power supply unit.
– Power supply unit okay: Check the voltages applied to P.C.B. LP 633: +24V_EM: X633L/B20.
– Pull off all plug-in modules. As soon as the machine is running: replug each plug-in module
– individually with the machine switched off; determine the defective module and repair it.
– Completely loosen the hydraulic compartment connections.
– Caution: J1 must now be fitted on P.C.B. LP 630 since, without it, the machine would not be able to
– perform the watchdog test. Be absolutely sure to remove the jumper again for hemodialysis
– operation.
– With the machine running, check the short circuit in the hydraulic compartment for 24-V supply and
– the valves and pumps for short circuit.
CPU-II failed
– CPU2 fails to communicate via the serial interface.
– The machine enters the safe state and must be switched off/on.
– AD 10 (adapter board from software version 3.0) has contact problems (up to and incl. layout „C“).
– The software versions of CPU1 and CPU2 are mismatching.
– Hardware defect on CPU2.

– Conductivity is recognized on the V84 electrodes.
– This error message is emitted for the first time at the end of the T1 test.
– The error can be acknowledged for the duration of one hemodialysis procedure by pressing the
– Dialysis Start key. It is, however, not possible to switch off the flow (Bergström-/ISO-UF operating
– mode). Should the error occur during Flow OFF, the flow is switched on automatically.
– First of all, it must be verified whether a Rinse Failure F01, F02 or F03 occurred during the previous
– disinfection procedure (see listing of cleaning program errors). Should this be the case, a disinfection
– program I to IV (not Dis V) must be completed correctly. A further possibility of elimination is to
– perform the calibration program under the NOVRAM menu item (Reset V84).
– Should this not be possible, the error memory of the machine can be read out.
– Should this neither be possible, the test described below can be performed:
– Remove the disinfectant.
– Switch the machine off and on again.
– Perform or skip the T1 test.
– Should the error message be displayed again at the end of the test, it was generated by a machine
– error F01, F02 or F03 and can be cleared only by taking the measures described above.
– Should the message not be displayed again, a second test can be performed:
– Reconnect the disinfectant.
– Set the UF rate and switch on the UF unit.
– Should the error occur at this moment, there is a leakage on V84 (see listing of cleaning program
– errors).

Handling of Error Messages of the BTM
The errors are classified into 8 categories according to the most significant digit of the error number
E0xxx
The measured value is beyond the allowed range.
E1xxx
The BTM is technically faulty.
E2xxx
There is an operating error which can be corrected. As soon as the problem is eliminated,
the BTM continues its function.
E3xxx
A grave operating error has occured. The BTM is switched off.
E5xxx
A value of the internal parameter memory (see Chapter B 12.4), which is open to change
By + service technicians only, is beyond the allowed range or the parameter memory is
faulty.
E6xxx
Software error.
E7xxx
An incident occuring during recirculation measurement resulted in an unsuccessful
termination of the measurement.
E8xxx
An incident during an active control function resulted in the termination of the control
function.
Grave Errors
Errors of the category E0xxx, E1xxx, E3xxx, E5xxx und E6xxx indicate a grave problem. For
reasons of safety, the BTM is turned off. In such an event, control of dialysate temperature is again left
to the dialysis machine. The BTM terminates all functions and only displays the error message. There
is no longer any influence on the treatment. A grave error can be recognized by all of the 7 LED’s
being switched off. Press RESET-key combination to restart the BTM. It then behaves in the same
way as after power-on.
Before pressing RESET, make sure that there is no defect or any other failure relevant to
safety.
Warnings / Indications
Errors of the category E2xxx, E7xxx and E8xxx do not result in a turnoff of the BTM. They are to
understand as indications or warnings for the user. In most cases, a fast flashing LED of a key in
connection with the concerned function indicates the error cause. Partly these messages are
answered by pressing ENTER; partly, they extinguish automatically as soon as the cause is
eliminated.
Handling of Error Messages
Error messages occur due to operating errors, inadmissible conditions while a control function or a
recirculation measurement is active, and technical defects.
Error messages are displayed as four-digit error numbers with the letter E in front. In Chapter C2
possible causes and the nessesary measures to take are listed for all error messages. If a grave error,
e.g. caused by a technical problem, occurs, the BTM will terminate operation, which is indicated by all
LEDs being switched off. The most frequent errors are:
E2001
Arterial blood line has not been detected.
E2002
Venous blood line has not been detected.
E2003
Both arterial and venous blood line have not been detected.
E2203
Temperature of sensor heads is to high for tube detection, (also see B4.4)
E7601
Blood flow has been changed during recirculation test.
E7801
During recirculation measurement a blood alarm has occured or dialysis treatment has been
completed.
E8800
Dialysis treatment was stopped or interrupted for a longer period of time while a control
program has been active.

Arterial sensor head temperature > 42°C.
Venous line temperature < 12°C.
Venous line temperature > 42°C.
Venous sensor head temperature < 12°C.
Venous sensor head temperature > 42°C.
Problem: The allowed temperature measuring range is 12°C to 42°C. This error may
occur
due to a technical defect of the BTM or the dialysis machine or in case of the BTM
being
used to measure fluids beyond the allowed temperature range.
Solution: First of all check, whether line temperature is really beyond the
range of 12-42°C
or adjacent to the limits. If this is not the case, do not continue using the BTM.
Call service.
The measured value of dialysate temperature is < 32 °C. Solution: Call service.
Dialysate temperature is > 41 °C and the blood pump is running (BFR > 10 ml/min).
Problem: As dialysate temperatures above 41 °C are critical, usually the BTM is
turned off, except the dialysis machine is placed in hot rinse mode. The BTM is not
able to determine for every type of dialysis machine whether it is in hot rinse mode or
not. Instead the blood flow rate is monitored and dialysate temperatures > 41 °C are
tolerated only if the blood pump stands still.
Solution: If the blood pump has been set in motion during hot rinsing or during the
phase of cooling down, wait until dialysate temperature has decreased below 41 °C.
Thereafter the BTM may be restarted with the RESET key combination. If the blood
pump has not been set in motion, the BTM or the dialysis machine is defect or
decalibrated, respectively.
The measured blood flow rate is not valid (negative, <-10 ml/min).
Solution: Check cable connection (20-pin cable to the monitor and to the blood
pump).
In case of recurrent errors call service.
The measured blood flow rate is > 550 ml/min. However, a maximum flow rate of 500
ml/min has been selected by the setting of the DIP switch (S 1; LP 906). The measured
blood fow rate is > 650 ml/min, whilst a maximum flow of 600 ml/min has been selected by
the setting of the DIP switch 2 (Sl; LP 906)
Solution: Check DIP switch no. 2 (S 1; LP 906) to make sure the right type of blood
pump has been selected (s. Chapter D3). If this does not correct the problem,
call service.
The measured recirculation is invalid (>= 1).
Problem: Possibly arterial and venous blood lines have been exchanged or have not
been inserted properly into the sensor heads!
Solution: Check the whole extracorporeal system.
E1 xxx Technical Defect
If errors of this category occur (left figure =1), there is a technical problem of the BTM (except E 1103:
configuration may not be correct).
60
E1031
E1032
Arterial sensor head does not reach thermal equilibrium.
Venous sensor head does not reach thermal equilibrium.
Explanation: During normal operation, the sensor head of the BTM is heated to the
temperature of the blood in the tube. This condition, called "thermal equilibrium of the
sensor head", is a prerequisite for a precise blood temperature measurement. After a
change in blood temperature it takes up to 3 minutes until equilibrium is reached
again. The error message appears if the equilibrium is not reached after 10 minutes.
Solution: If a sensor head is unusually hot the service should be called. Check the
two fuses Fl and F2 on the BTM board (LP 906). If they are both intact or if one of
them blows repeatedly, call the service.
E1101
E1102
E1103
CRC error in message from dialysis machine.
Instruction cannot be executed by dialysis machine.
Timeout-error during data reception (microprocessor-controlled dialysis-machine).
Problem: All 3 messages occur due to data transfer problems between BTM and
dialysis machine. In case of El 103, the DIP switch no. 3 (S 1; LP 906) may be set
wrong.
Solution: Check position of DIP switch no. 3 (Sl; LP 906) for selection of the dialysis
machine type (in case of El 103). Check cable connection between BTM and dialysis
machine. If you are unable to remove the problem this way, call service.

Timeout error: No answer to instruction received from dialysis machine.
Communication dialysis machine to communication coprocessor interrupted.
Problem: All messages occur due to data transfer problems between BTM, dialysis
machine and communication coprocessor (if present). In case of El 107, the DIP
switch no. 3 (Sl; LP 906) may be set wrong.
Solution: Check position of DIP switch no. 3 (S 1; LP 906) for selection of the dialysis
machine type (in case of El 107). Check cable connections between BTM, dialysis
machine and communication coprocessor (if present). If you are unable to solve the
problem this way, call service.
Hardware error on board LP906.
The parameter memory (EEprom) is defect; CRC-test was negative.
The program memory (Eprom) is defect; CRC-test was negative.
Solution: BTM is no longer operable; service has to be called.

E1301
E2xxx Operating Errors
Messages of this category indicate removable problems mostly due to operating errors. Error no.
Explanation
E2001
E2002
Arterial blood line has not been detected.
Problem: While the venous blood line has been detected at least 2 minutes ago, the
arterial line has not been detected. Therefore no control function or recirculation
measurement can be activated. This message also occurs if blood line temperature is
below 33.5°C.
Solution: Check arterial blood line to make sure it is properly inserted into the arterial
(upper) sensor head and that the sensor head is closed. After the line has been
inserted properly, it may take some time (up to about 1 minute) until the message
does no longer appear on selection of a control function or recirculation
measurement.
Venous blood line has not been detected.
Problem: While the arterial blood line has been detected at least 2 minutes ago, the
venous line has not been detected. Therefore no control function or recirculation
measurement can be activated. This message also occurs if blood line temperature is
below 33.5°C.
Solution: Check venous blood line to make sure it is properly inserted into the venous
(lower) sensor head and that the sensor head is closed. After the line has been
61
E2003
inserted properly it may take some time (up to about 1 minute) until the message does
no longer appear on selection of a control function or recirculation measurement.
Both arterial and venous blood lines have not been detected.
Problem: Neither of the two blood lines has been detected, while the blood pump has
been running for at least 2 minutes. Therefore no control function or recirculation
measurement can be activated. This message also occurs if the blood temperatures
of both lines are below 33.5 °C.
Solution: Check both blood lines to make sure they are inserted properly into the
sensor heads and that the sensor heads are closed. After the lines have been
inserted properly, it may take some time (up to about 1 minute) until the message
does no longer appear on selection of a control function or recirculation
measurement.
Messages E2001 - E2003 may occur especially if a control function or recirculation measurement has
already been selected during priming process (which does not make sense). In the event that one of
these 3 messages occurs, flashing LED's on the keys T-ART or T-VEN indicate which line (arterial,
venous or both) is to be checked (see also Chapter B4.4).
E2202
E2203
If this operating mode is selected, blood line temperatures (not fistula temperatures) are
displayed.
Explanation: Display of line temperature has been selected by DIP switch no. 6 (S 1;
LP 906). After starting of the BTM this message simply indicates the choosen
operating mode, avoiding that line temperature instead of fistula temperature will be
displayed accidentally for a longer period of time.
Solution: If display of the line temperatures is intended, the message can be erased
by pressing ENTER. On the other hand, if fistula temperatures should be displayed,
turn off the dialysis machine, correct position of DIP switch no. 6 (S 1; LP 906) and
than restart the dialysis machine.
Temperature of sensor heads is to high.
Explanation: At the beginning of a dialysis treatment and during the priming process,
respectively, the BTM checks whether the blood lines are properly inserted into the
sensor heads. For this purpose the temperature of the sensor heads has to be initially
below 32.5°C. If this is not the case, the display of this error message demands to
wait until sensor heads have cooled down adequately. Afterwards the message
extinguishes automatically. This message usually occurs if there is a longer period of
time with the blood pump not working following the priming procedure. Consequently
the BTM passes into the inactive mode and then restarts tube detection (see also
Chapter B4.3).
Solution: Wait until sensor heads have cooled down adequately and message
extinguishes automatically. However this message can be skipped by pressing
ENTER. In this case
detection of tubes is not reliable any longer! The user is responsible for
deactivating an essential safety feature of the BTM!
E3xxx Grave Operating errors
Messages of this category indicate operating errors which result in turnoff of the BTM.

Arterial and venous line exchanged and inserted this way into the sensor heads. This error
will be detected some time after starting a control program.
Solution: Insert lines properly; press RESET to restart BTM.
Maximum operating time of the BTM has been attained.
Solution: Press RESET to restart BTM.
Dialysis machine without microprocessor control: The connection between the BTM and
monitor of the dialysis machine (LP433) is not installed or interrupted.
Solution: Turn off dialysis machine, install connection properly, restart dialysis
machine.
E5xxx Inadmissible Data in Parameter Memory (EEprom)
Errors of the category E5xxx occur only after an inadmissible input in the parameter memory, e.g.
through the service technician. The parameter memory is loaded with calibration parameters as well
as a plurality of user specific parameters, which especially allow to set options for control functions
and for the recirculation measurement (see Chapter B12.4, D6). For each of the parameters upper and
lower limits are prescribed, which are checked every time the BTM has been turned on. If the stored
parameter is beyond these limits an error message is displayed and the BTM deactivated. The
following table lists the error number and the inadmissible parameter. The parameter in question has
to be corrected by a service technician. Errors also occur if parameters are inconsistent. In the event
of E5000 - E5021 occuring the last two figures to the right represent the parameter number in the
parameter memory. The BTM is not servicable until all parameters are within the limits prescribed.
Error no.

E6xxx Software Error
Errors of type E6xxx are software errors. In the event of an error of this type occuring, the error
number should absolutely be told to the service technician. If the error has no problematic
consequences, working with the BTM can be continued.
E7xxx Termination of Recirculation Measurement
Several conditions may result in an unsuccessful termination of recirculation measurement. Previous
to bolus production, arterial and venous temperatures as well as blood flow have to be adequately
constant. If this is not attained 10 minutes after selecting the recirculation test, recirculation
measurement will break off and an error message will appear on display. Each of the three figures on
the right of the error number separately indicates a reason for the breakoff, if the figure is not zero.

Explanation
Arterial blood temperature increases or decreases too rapidly.
Venous blood temperature increases or decreases too rapidly.
Variation of arterial blood temperature in time is too high.
Variation of venous blood temperature in time is too high.
Blood flow rate is not sufficiently constant.
Blood flow rate is too low (<120 ml/min)
E.G. error no. E7203 indicates that blood flow rate is too low and arterial as well as
venous temperature decrease or increase too rapidly.
The following error messages indicate conditions which occurred during bolus production and
bolus analysis:
Error no.
Explanation

has
E7603
Blood flow rate has been changed by user during recirculation test
Unexpected reaction of venous temperature: Instead of an expected increase a decrease
been observed.
No positive temperature bolus has been recorded within 4 minutes after adjusting dialysis
temperature.
E8xxx Termination of the Control Program
After selection of a control program the BTM first waits for both blood temperatures and the the blood
flow rate to be sufficiently constant. If this is not attained within 15 minutes after selection of the
program, the control function will terminate and an error message will be displayed. Each of the three
figures on the right of the error message separately indicates a reason for the turnoff, if the figure is
not zero.
Error no.

Blood flow rate is too low «120 ml/min).
E.g. the error message E8231 means that blood flow rate is too low, the temporal variation of the
arterial as well a.s the venous blood temperature is too high, and the arterial blood temperature
increases or decreases to rapidly.
The remaining messages are provoked by finishing the dialysis treatment or interruptions over a
longer period of time.

The normal operating mode of the BTM could not be attained within 15 minutes after
starting the control program.
Problem: E.g. repeated blood alarms.
Dialysis treatment was stopped or interrupted for a longer period of time while a control
program has been active.
C3 Common Questions
In this chapter questions shall be answered and aids be given to solve problems that might rise with
the daily use of the BTM. Each problem is annotated briefly and a reference to the chapters containing
detailed explainations is given. This way tedious looking through the operating instructions shall be
avoided.
The questions and problems are classified in 3 categories. In the event of a problem occuring look
over the headings of the different categories and try to find the one that comes closest to your
problem.
Problem: The Meaning of the Displayed Information of the BTM is Unknown
.36.52
A figure with a point in front is being displayed. The point indicates that the BTM is not in
normal operation mode at present. Either normal operating mode has not been reached at
the beginning of dialysis (Chapter B4.3 - B4.5) or a blood alarm has occured
(Chapter B 10.1).
E 2203
The letter 'E' followed by any four-digit figure (except '8888') is being displayed. This way
the BTM displays a warning, a remark or an error message. General information concerning
this is given in Chapter B10.2. For information on a particular message refer to the list of all
error messages in Chapter C2.
E8888 The opposite indication appears in connection with the self-testing of the BTM immediately
after starting it (Chapter B4.1). If the indication does not extinguish after a few seconds, the
DIP switch no. 1 (Sl; LP 906) is set wrong (Chapter D3).
≡ -100
The symbol on the left followed by a figure is being displayed. The symbol indicates that the
value shown refers to a control function. Either control parameters are being entered
(Chapter B6.1, B7.1) or displayed (Chapter B 12.1).
c –13.4 The symbol on the left followed by a figure is being displayed. The symbol indicates that the
value shown refers to the recirculation measurement. Either bolus parameters are being
entered (Chapter B 11.2) or the the result of the recirculation measurement is being
displayed.
-This indication shows that the BTM is inactive (Chapter B4.3).
- - This indication appears whenever the attempt is made to call up data not available at
present with the RESULT-key (Chapter B8.2, B5.5, B12.1, B12.2).
- - - - - It is indicated that the blood lines have not yet been detected so that the respective fistula
temperature or thermal energy flow rate cannot be displayed (Chapter B4.4, B5.2).
Problem; Unknown Meaning of a Steadily Shining or Flashing LED
At first it has to be distinguished between steadily shining and fast, slowly or intermittently flashing
LEDs (definition see Chapter B2).
LED-Status
One of the 4 green LEDs shows a steady light.
The LED of the T-ART or T-VEN key is slowly Hashing.
The LED of the 'E' key is flashing fast.
The LED of the T point SET or 'E point
SET key shows a steady light
The LED of the T point SET or 'E point
SET key is slowly Hashing.
Explanation
The value of the parameter indicated
on the key is being displayed
(ChapterB5.1).
The arterial or venous sensor head
has not yet reached thermal balance
(Chapter B5.3).
While selecting a control program, the
BTM allows resetting of the energy
balance being displayed (Chapter
B6.1.B7.1).
The respective control function is
being active (Chapter B6.1,B7.1).
Parameter input for the respective
control function is expected (Chapter
B6.1, B7.1). The function is not active
yet.

The LED of the T point SET or 'E point
SET key is flashing fast.
The LED of the REC key shows a constant light.
The LED of the REC key is slowly flashing.
The LED of the REC key is Hashing fast.
The LED of the REC, T point SET or 'E point
SET is flashing intermittently.
No LED is on and 'Exxxx' is being
displayed (xxxx= any figure).
66
On account of a problem the
respective control function was
terminated (Chapter B6.3, B7.3).
Recirculation measurement is being
active (Chapter B8.1)
Parameter input for recirculation
measurement (Chap. Bl 1.2) is
expected.The measurement is not
active yet. If an injection bolus has
been selected, the Hashing indicates
that injection is not allowed yet
(Chapter B11.3).
The recirculation measurement is
finished.
The measuring result or an error
message is
being displayed or can be called
(Chapter B8.2).
During the respective control function
or the bolus production a dialysate
temperature limit was reached
(Chapter B 10.3).
A grave error has occured (Chapter B
10.2).
The BTM has stopped operation.
