LAST EDITED: 00-03-28 JoFo.

Error messages from AK 200 will now be prepared for three different
error levels depending on the possibility to recover or restart.

1. Unconditional technical error. No restart or recovery attempts.
This will be used where patient safety cannot be guaranteed in presence
of the error.This could be caused by some serious hardware error.

2. Conditional technical error. Continued treatment is allowed given that
a certain condition is fulfilled or a confirmation has been made.
These errors are marked with "/" before the error code, "/FCN 5.02 002".

3. Recoverable technical error. A number of restart attempts will
be made. If this is unsuccessful an unconditional or conditional
technical error will appear.
These errors are marked with "*" before the error code, "*FCN 8.09 001".

The letters [F,T,D,S] can follow the names of the functions.
[F,.....] means that the error codes can appear during the function
checks.
[.,T,...] means that the errors can appear during treatment.
[...,D,.] means that the errors can appear during rinse or disinfection.
[.....,S] means that the errors can appear during service mode.

LED STATUS MESSAGES

TIME DISPLAY ERROR MESSAGES/MAIN BOARD LED STATUS CPU A IN BM200 / BM202.

1. CPU INIT
--------

"FCh" is displayed during startup. BM main board LED status
indicates the test that is in progress.

"Exy" is displayed when a test fails. BM main board LED status
indicates the test that failed.The correspondence between
time display and main board LED indication will be:

LED indicator V15-V17 = Least significant digit on time display (y).
V12-V14 = Most significant digit on time display (x).
V10,V11 = Not significant on time display.

NOTE. The appearance of the first LED status code 11000000 may,
besides the status explained below, also be considered as
a 'CPU A is executing' indication.
Also note,that it is advisable NOT to interfere with the
machine during start up test other than when explicitly
advised to do so.(Non-relevant error messages may occur)

Status codes 11 000 000 through 11 101 111 are BASIC tests performed before
the operating system is allowed to start.

Flow generator transducer calibration function. (CPU D).

FCN 4.04 000 = Case error. The program is not working properly.

FCN 4.05, FLOW MEASURING FUNCTION (CPU D)
Purpose:
* NORMAL OPERATION: The signal TMO0 is used for the synchronization of the
UF flow measurement. TMO0 is a 401.44 Hz square wave (50% duty cycle)
with TTL levels. It switches the magnetic field in the UF measuring
unit and controls the sampling of the received flowsignals. The two
measured flow signals are amplified at the UF preamplifier board. The
flow signals then passes multiplexers, are amplified and sampled on the
FM CPU board. The sampled voltages are converted to frequen-
cies that are measured by two counters that both are contained in IC94
on the FM CPU board. FCN 4.05 calibrates the counter values
and creates the variables FRR(FR_CH1$RATE) and FRR(FR_CH2$RATE).
FRR(FR_CH1$RATE) is the flow through channel 1 and it has the unit
ml/min. FRR(FR_CH2$RATE) is the flow through channel 2.
FRR(FR_UF$RATE) is calculated as the difference between the flow
through channel 2 and the flow through channel 1. FRR(FR_UF$RATE) has
the unit 1 l/h.
The UF volume FRR(FR_UF$VOL) is calculated. It's unit is 1 l.
* EVERY 30 MINUTES: A self calibration is done twice an hour.
The normal operation of the self calibration is as follows:
1 The measuring system is calibrated by first grounding the input and
then applying a reference voltage to the input.
2 ZEVA is opened and DIVA/BYVA are closed so that no flow passes the
flow cell. The zero flow signals are measured for 15 seconds and the
program checks that the signals are stable. Flow transducer offsets
are calculated. If necessary the measurement is prolonged for 15s.
3 BYVA is opened and DIVA/ZEVA are closed so that the same flow passes
through flow channel 1 and flow channel 2. The flow signals are
measured after 15s. The measurement continues for 15s and the
program checks that the signals are stable. If necessary the
measurement is prolonged for 15s. The program checks that
the parameters FRR(FR_UFR$TOLERANCE) and FRR(FR_UFR$OFFSET) have not
changed too much since the last self calibration. If a self
calibration fails, then it is repeated after 5 minutes.
* VALVE LEAKAGE TEST : The direct valve, the bypass valve and the zeroing
valve are leakage tested during the function checks. DIVA, BYVA and
ZEVA are closed. The flow output pump tries to force fluid through the
closed valves, and the flow measuring function FCN 4.05 checks that no
flow is leaking through them.

* CALIBRATION: The calibration is done in service mode, and it consists
of the following steps:

1 Tempered fluid flows through both the flow channels for 10 minutes.
2 The linearity of the UF measuring unit is checked by letting three
different flows flow through both the channels.
3 The offsets are calculated by not having any flow through the
channels.
4 The channel 1 coefficient is calculated by letting the flow through
channel 1 fill a reference volume.
5 The channel 2 coefficient is calculated by having the same flows
through both the channels.
6 The calibration parameters are verified.

If "Internal" mode is selected to update offset's and channel 2
coefficient then only steps 1,3 and 5 is performed.

NOTE! The channel 1 flow signal is forwarded through the VFC channel 2
and vice versa.
NOTE! The most probable error explanations are described the first.

broken or the driver IC113 is broken.
* UF DRIVER BOARD,TMO0: TMO0 short circuit. If TMO0 becomes correct when
the flow transducer is disconnected then the error is probably caused
by a broken IC2 on the UF driver board.

The VFC channel 2 has been connected to 0V.
The pulse counter has measured a frequency that differs too much from
the frequency that usually is measured when 0V is connected.

Technical description of conditions for occurring:
(VFC2.VALUE-8907) > 2000 for 2s
OR
(VFC2.VALUE-8907) < -2000 for 2s.

VFC2.VALUE = SRR(11) and has the unit 0.08 ml/min.
VFC2.OFFSET = SRR(12) holds the result from the offset measurement
and has the unit 0.08 ml/min.

Some possible explanations why the error has occurred:
* FM CPU BOARD: The VFC, IC38 or some of the passive components around it
is broken. Problems have been noted if the capacitors C46 and C50
are of ceramic type. From approx. FM serial No. 4750 these capacitors
are changed to a polypropylene type (100 116 003). Please refer to
General Information 179 for more details.
* FM CPU BOARD,TMO0: The signal TMO0 is not present or the levels are out
of the TTL specification (low level<0.5 Volt, high level>2.4 Volt). One
reason for this error could be that there is a bad connection between
the CPU, IC101 on the FM CPU board and its socket. The socket
should be manufactured by AMP. Sockets from other manufacturers have
caused problems.
* FM CPU BOARD: The timer, IC94 on the FM CPU board is not working
properly. The sampling pulses at pin 2 and 3 are incorrect or missing.
The pulse duration should be 50 microseconds and the pulse repetition
time should be 2.49 milliseconds. The pulses should have TTL levels.
* FM CPU BOARD,TMO0: The signal TMO0 is incorrect as the CPU, IC101 is
broken or the driver IC113 is broken.
* UF DRIVER BOARD,TMO0: TMO0 short circuit. If TMO0 becomes correct when
the flow transducer is disconnected then the error is probably caused
by a broken IC2 on the UF driver board.
* FM CPU BOARD: IC16 is broken.
* FM CPU BOARD: The sample and hold circuits IC26 or IC28 are broken.
* FM CPU BOARD: The multiplexer IC9 is broken.
* FM CPU BOARD: The amplifier IC20 or some of the components around it
are broken.

SRI(37) has the unit 1 mA, and it corresponds to
FRI(FI_UF$COIL$CU) / 10.

Some possible explanations why the error has occurred:
* UF PREAMP BOARD: The IC that generates the signal MFC0 is broken.
* UF DRIVER BOARD: Something is broken on the UF driver board.
* FM CPU BOARD,TMO0: The signal TMO0 is not present or the
levels are out of the TTL specification (low level<0.5 Volt,
high level>2.4 Volt). One reason for this error could be that there is
a bad connection between the CPU, IC101 on the FM CPU board
and its socket. The socket should be manufactured by AMP. Sockets from
other manufacturers have caused problems.
* FM CPU BOARD,TMO0: The signal TMO0 is incorrect as the CPU, IC101 is
broken or the driver IC113 is broken.
* UF DRIVER BOARD,TMO0: TMO0 short circuit. If TMO0 becomes correct when
the flow transducer is disconnected then the error is probably caused
by a broken IC2 of the UF driver board.
* CABLINGS: Some cablings are broken or short circuit.
* UF MAGNETIZATION COIL: Broken or short circuit.

values that are stored in the E2PROM are used, and the difference is
allowed to be 1.5 ml/min instead of 1 ml/min.)

are changed to a polypropylene type (100 116 003). Please refer to
General Information 179 for more details.
* FM CPU BOARD,TMO0: The signal TMO0 is not present or the levels are out
of the TTL specification (low level<0.5 Volt, high level>2.4 Volt). One
reason for this error could be that there is a bad connection between
the CPU, IC101 on the FM CPU board and its socket. The socket
should be manufactured by AMP. Sockets from other manufacturers have
caused problems.
* FM CPU BOARD: The timer, IC94 on the FM CPU board is not working
properly. The sampling pulses at pin 2 and 3 are incorrect or missing.
The pulse duration should be 50 microseconds and the pulse repetition
time should be 2.49 milliseconds. The pulses should have TTL levels.
* FM CPU BOARD,TMO0: The signal TMO0 is incorrect as the CPU, IC101 is
broken or the driver IC113 is broken.

Purpose:
* Checks that the main flow is one of the allowed main flow in the monitor
* Calculates the low (negative) limit and the high (positive) limit for
the fluid pressures. The low limit is the flow output pressure, and
the high limit is the flow input pressure.
* Calculates restrictor coefficients for flow output pump and flow input
pump.
( PRESSURE = RESTRICTORCOEFF * FLOW * FLOW,
where PRESSURE is measured between the restrictor and the pump, and
FLOW is the flow through the restrictor. )
* Calculates calibration coefficients and calibration offsets for the
flow input pump and the flow output pump.
( DUTYCYCLE = CALCOEFF * DIFFPRESS + CALOFFSET,
DUTYCYCLE is converted to an output voltage for the pump.
FRI(FI_E$PUMP$OUT$DTCY) = 50 (=5%)
==> flow output pump voltage = 0.05 * max voltage.

==> flow output pump voltage = 0.95 * max voltage.
1 unit of FRI(FI_E$PUMP$OUT$DTCY) = 0.1%
DIFFPRESS is the pressure over the pump.
DIFFPRESS over fl out pump =
FRI(FI_HPG$SET)-FRI(FI_E$PR$FLOW$OUT).
DIFFPRESS over fl in pump =
FRI(FI_E$PR$FLOW$IN) - FRI(FI_HPG$SET).
FRI(FI_E$PR$FLOW$OUT) is about -400mmHg.
FRI(FI_E$PR$FLOW$IN) is about +350mmHg.
1 unit of FRI(FI_E$PR$FLOW$OUT) = 0.1mmHg)

FCN 5.10 003 DIALYSIS PRESSURE TOO LOW OR TOO HIGH DURING [T]
THE DIRECT AND TARATION VALVE TEST.
General description of conditions for occurring:
PD was more than +50 mmHg or less than -50 mmHg during direct
valve or taration valve leakage tests. Should have been near
0 mmHg as RFVA is open and the tubes from heating vessel and
safety bypass unit is filled with air and the pressure in
heating vessel is 0 mmHg.

Technical description of conditions for occurring:
Functional check of CPU D was running.
Air was entered into the deairating chamber by opening the
recirculation flow valve (RFVA).
Direct and taration valve test was started.
The direct valve (DIVA) and TAVA valve (TAVA) were closed.
The recirculation flow valve (RFVA) was opened.
The dialysis pressure (Pd) was more than +50 mmHg or less
than -50 mmHg for more than 5 seconds.

Some possible explanations why the error has occurred:
* Tubes was removed from Safety Bypass Unit before the functional
check was ready.
* TAVA broken, constantly open.
* DIVA broken, constantly open.
* Broken or bad calibrated dialysis pressure (Pd) transducer.
* Fluid path from heating vessel to Safety Bypass Unit obstructed.

TARATION VALVE LEAKAGE TESTS.
General description of conditions for occurring:
Not possible to control the high pressure guard (HPG) pressure
to the value of the dialysis pressure (Pd) within 120 seconds.

Technical description of conditions for occurring:
Functional check of CPU D was running.
Direct and taration valve test was started.
The direct valve (DIVA) and TAVA valve (TAVA) were closed.
The recirculation flow valve (RFVA) was opened.
The Flow Input Pump starts to control high pressure guard
pressure (HPG) to be equal to the pressure on the other side
of the direct valve (DIVA) and taration valve (TAVA) measured
by dialysis pressure transducer,Pd.
The controlled pressure (HPG) differed more than +/5 mmHg for
more than 120 seconds from dialysis pressure (Pd).

Some possible explanations why the error has occurred:
* FLOW OUTPUT PUMP RESTRICTOR: The restrictor is dirty.
* FLOW OUTPUT PUMP: The pump is not working properly.
* The flow system before bubble trap 1 causes an unstable level in
bubble trap 1.
* FLOW OUTPUT PUMP PRESSURE TRANSDUCER: Not working properly.

Check if flow output pump pressure (SRI-10) is stable. The
pressure should be -350 to -425 mmHg and not vary more than
+/- 2 mmHg.

FCN 5.10 005 PRESSURE CONTROL TIMEOUT DURING THE DIRECT VALVE [T]
LEAKAGE TEST.

General description of conditions for occurring:
Not possible to control the high pressure guard (HPG) pressure
within 120 seconds to the value requested by the direct valve
(DIVA) leakage test.

Technical description of conditions for occurring:
Functional check of CPU D was running.
Direct and taration valve test was started.
The direct valve (DIVA) and TAVA valve (TAVA) were closed.
The recirculation flow valve (RFVA) was opened.
The test was successfully proceeded until the start of the
direct valve leakage test.
The Flow Input Pump starts to control high pressure guard
pressure (HPG) to the requested value of the direct valve
leakage test. The test pressure was Pd - 300 mmHg or the minimum
allowed system pressure estimated during the Flow System
Calibration state of the functional check.
The controlled pressure (HPG) differed more than +/5 mmHg
from requested value for more than 120 seconds.

Some possible explanations why the error has occurred:
* TAVA leaking.
* DIVA leaking.
* FLOW INPUT PUMP RESTRICTOR: The restrictor is dirty.

Some hints of what to do if the error occurs:
Check if flow output pump pressure (SRI-10) is stable. The
pressure should be -350 to -425 mmHg and not vary more than
+/- 2 mmHg.

Check if channel 1 flow rate,SRI(25) is negative ( < -10 ml/min) or
unstable caused by air sucked through tubings from Safety Bypass Unit
then error is probably caused by big leakage of the DIVA valve.

Check if channel 2 flow rate,SRI(26) is positive ( > +10 ml/min) or
unstable caused by air sucked through tubings from Safety Bypass Unit
then error is probably caused by big leakage of the TAVA valve.

How the CPUs are connected:
CPU A ===== CPU B ===== CPU C ===== CPU D (physical connections)
----> ----> (logical connections)
<---- <----
---------------------------->
<----------------------------
Example: CPU C is physically connected to CPU B and to CPU D.
CPU C is logically connected to CPU B.
A message from CPU C to CPU D is sent as follows:
From C to B, from B to A, from A via B and C to D.

How the safe bus is connected:
The safe bus is a single conductor which lets current flow from a
current generator Q8 and V23 on the BM CPU board to a
terminator IC52 on the FM CPU board. The safe bus has the
signal names SBSI and SBSO on the BM CPU board, and the signal names
SBSI, SBSF and SBSO on the FM CPU board. The LED V46 on the FM CPU
board is lit when NO current is flowing through the safe bus.
The following circuits control the current through the safe bus:
* The CPU B watchdog IC 36 on the BM CPU board uses the signal
SWBC to control the current generator.
* IC18 on the BM CPU board controlled by the CPU B watchdog and
the power supply alarm.
* IC77 on the FM CPU board controlled by the CPU C watchdog
IC73 on the FM CPU board and the power supply alarm.
The following optocouplers sense if current is flowing through the
safe bus:
* IC19 on the BM CPU board.
The CPU B watchdog senses the safe bus status but takes no action.
* IC18 on the BM CPU board.
The 24 volt supply for the blood pump(s) is turned off if no
current is flowing through the safe bus.
* IC39 on the FM CPU board.
The 24 volt supply for the direct valve, the inlet valve, the flow
output pump and the flow input pump is turned off if no current is
flowing through the safe bus.
* IC77 on the FM CPU board.
The CPU C watchdog IC73 on the FM CPU board senses the safe
bus status and resets CPU C, CPU D and CPU E if no current is
flowing through the safe bus.

Note! Sometimes the 8.10 errors can only be observed in the diagnostics
error buffer!

incorrect value. The CPU A supervisory task should have updated this
variable correctly.

Technical description of conditions for occurring:
do every 200 ms:
if FRB(FB_D$A$TASK$SUPER$CNT) <> BRB(BB_A$D$TASK$SUPER$CNT) + 1 then
( CPU A supervisory task has executed and should have set
BRB(BB_A$D$TASK$SUPER$CNT) = FRB(FB_D$A$TASK$SUPER$CNT) + 1 )
if BRB(BB_A$D$TASK$SUPER$CNT) <> FRB(FB_D$A$TASK$SUPER$CNT)+1 then
Send the error code "FCN 8.12 002"
FRB(FB_D$A$TASK$SUPER$CNT) = BRB(BB_A$D$TASK$SUPER$CNT) + 1

The AK 200 have problems communicating with the BVS subunit.
The problem can occur if the CPU A interface board (connected on the
BM board) or the BVS subunit board is broken or if the cable between
these boards is not connected properly or broken.
2. Errors in the BVS subunit. Before any further actions make sure that
the aluminium block in the BVS holder is clean. To have a relative blood
volume value during dialysis, the arterial blood flow must be more than
180 ml/min.
