LAST EDITED: 01 03 28

Error messages from AK 90 can be divided in three groups:
* Unconditional technical errors. No restart attempts are done.
The patient safety cannot be guaranteed if the error is present.
* Conditional technical errors. Continued treatment is allowed if
a certain condition is fulfilled or a confirmation has been made.
* Transient technical errors. A number of restart attempts will
be done. If they are unsuccessful an unconditional or conditional
technical error will appear.

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.

The LED status codes for identifying errors detected during
startup code execution imediately after CPU reset.
The code is shown on five of the leds in led array IC 93
sitting next to the CPU at the bottom of the CPU-board.
These errors are all unconditional and stop the monitor complete.

FCN 2.20, FLOW MEASURING FUNCTION
Purpose:
* NORMAL OPERATION: The signal TMO0 is used for the syncronisation 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 recieved 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
CPU board (K13017). The sampled voltages are converted to frequen-
cies that are measured by two counters that both are contained in IC27
on the CPU board (K13017). FCN 2.20 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$VOL) is calculated. It has the unit 1 l.
* EVERY 30 MINUTES: A self calibration is done twice an hour.
The normal operation of the self calibration is as follows:
1 The measuring system is calibrated by first grounding the input and
then applying a reference voltage to the input.
2 ZEVA is opened and DIVA/BYVA are closed so that no flow passes the
flow cell. The zero flow signals are measured for 15 seconds and the
program checks that the signals are stable. Flow transducer offsets
are calculated. If neccessary the measurement is prolonged for 15s.
3 BYVA is opened and DIVA/ZEVA are closed so that the same flow passes
through flow channel 1 and flow channel 2. The flow signals are
measured after 5s. The measurement continues for 15s and the
program checks that the signals are stable. If neccessary the
measurement is prolonged for 15s. The program checks that
the parameters FRR(FR_UFR$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.

* 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.

Transient error.
Unconditional error if more than three errors during one treatment.

General description of conditions for occuring:
The UF measurement multiplexers are not selecting the correct data.

Technical description of conditions for occuring:
One part of the flowmeasuring code CALC_UF_VFC_VAL updates the
variable MUX$CHANNEL with data that will be output on the outport
The procedure FETCH_UF_VFC_VAL is activated by an interrupt
once a second. It selects which data should be let through
the MUXes IC 35, IC 36, IC 41 on the CPU board (K13017).
This is done by giving the variable FM$OUTPORT$B$M the data from
the variable MUX$CHANNEL, and then putting out that data on the
outport IC 48 on the CPU board (K13017). (Signals UIS0-UIS4).

Another part of the code (CALC_UF_VFC_VAL) has detected that the
5 lowest bits of the varible FM$OUTPORT$B$M have incorrect values.

Some possible explanations why the error has occured:
* SOFTWARE: The program is not executing correctly.
* CPU BOARD: The procedure FETCH_UF_VFC_VAL has not been activated
by any interrupt.
* The counter IC 27 on the CPU board (K13017) is broken so that
there is no 1 Hz frequency on signal IRUF.
* The interrupt controller IC 79 on the CPU board (K13020) is broken.
* CPU BOARD: The RAM, IC66 is broken. (drawing K13020)

(K14013) P54 and the UFM DRIVER BOARD (K11195) P51. There could also
be a short circuit.
* UFM DRIVER BOARD (K11195): Q1,Q2,Q3,Q4,Q5, IC1,IC2,IC3,IC4,IC5 or IC6
are broken.
* CABLINGS: There is a bad connection between the UFM DRIVER BOARD
(K11195) P52 and the UF magnetisation coil. There could also
be a short circuit.
* UF MAGNETISATION COIL: Broken or short circuit.
* CABLINGS: There is a bad connection between the UFM PREAMP BOARD 2
(K14013) P53 and the CPU BOARD (K13017) P105. There could also
be a short circuit.
* UFM PREAMP BOARD 2 (K14013): The voltage reference IC3 or the
amplifier IC1 are broken.
* CPU BOARD (K13017): IC 29 is broken so that timer 1 does not output
any frequency.
* CPU BOARD (K13017): IC 27 is broken so that timer 1 and 2 do not
output correct frequencies. The pulse duration
should be 50 microseconds and the pulse
repetition time should be 2.49 milliseconds.
It is also possible that counter 3 or 4 is not
counting a correctly.
* CPU BOARD (K13017): The VFC, IC28 or IC30 is broken.
* CPU BOARD (K13017): The sample and hold circuit IC32, IC33, IC39 or
IC40 are broken.
* CPU BOARD (K13017): The multiplexer IC35, IC36 or IC41 is broken.
* CPU BOARD (K13017): The amplifier IC34, IC31 or some of the
components around it are broken.
* CPU BOARD (K13017): The outport IC48 is broken.
* CPU BOARD (K13017): The outport IC54 is broken. The signal UFFQ is not
present or the levels are out of the TTL
specification (low level<0.5 Volt, high>2.4 Volt).
The signal UFFQ is called TMO0 on the UFM PREAMP
BOARD 2 and on the UFM DRIVER BOARD.
* 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 K11195.

FCN 2.20 011 SELF CALIBRATION PARAMETERS DIFFER TOO MUCH FROM
THE LAST SELF CALIBRATION [T]
Unconditional error.

General description of conditions for occuring:
A self calibration was run. It failed as the values of the variables
FRR(FR_UFR$TOLERANCE) and FRR(FR_UFR$OFFSET) had changed too much since
the last self calibration. A new self calibration was run after 5
minutes. It did also fail for the same reason.

Technical description of conditions for occuring:
The following parts of the self calibration executed successfully
without any errors:
VFC channel 1 reference measurement (NO error 2.20 006)
VFC channel 2 reference measurement (NO error 2.20 007)
VFC channel 1 offset measurement (NO error 2.20 008)
VFC channel 2 offset measurement (NO error 2.20 009)
Flow offset calibration (NO error 2.20 015)
Differential flow calibration. The same flow through channel 1 and
channel 2. The following parts succeded:
NO error 2.20 015
NO error 2.20 014

CALIBR DIFF FLOWnew differed more than 1 ml/min from CALIBR DIFF
FLOWold

A new self calibration was done after 5 minutes.

CALIBR DIFF FLOWagain differed more than 1.0 ml/min from CALIBR DIFF
FLOWnew AND CALIBR DIFF FLOWagain differed more than 1.0 ml/min from
CALIBR DIFF FLOWold

EXPLANATIONS:
CALIBR DIFF FLOW is the calibrated differential flow. It is stored
in the variable FRR(FR_UF$RATE) and has the unit l/h. The following
equation is used to calculate it:
CALIBR DIFF FLOW =
0.048 * ( UNCALIBR DIFF FLOW +
FRR(FR_UFR$TOLERANCE) * UNCALIBR CH1 FLOW -
FRR(FR_UFR$OFFSET) )

0.048 is an approximate value that varies for different flow
measuring units.
UNCALIBR DIFF FLOW has the unit 0.08 ml/min.
UNCALIBR CH1 FLOW has the unit 0.08 ml/min.
NOTE! VFC channel 2 takes care of flow channel 1.

CALIBR DIFF FLOWold is a CALIBR DIFF FLOW that is calculated using
the values of FRR(FR_UFR$TOLERANCE) and FRR(FR_UFR$OFFSET) from the
last self calibration. (If there is no last self calibration then the
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.)

CALIBR DIFF FLOWnew is a CALIBR DIFF FLOW that is calculated using
the values of FRR(FR_UFR$TOLERANCE) and FRR(FR_UFR$OFFSET) from the
main self calibration.

CALIBR DIFF FLOWagain is a CALIBR DIFF FLOW that is calculated using
the values of FRR(FR_UFR$TOLERANCE) and FRR(FR_UFR$OFFSET) from the
self calibration that is done 5 minutes after the main self
calibration.

Some possible explanations why the error has occured:
* FLOW CELL: The flow cell has been coated by dirt.
* FLOW CELL: The flow cell is broken.
* FLOW CELL: The resistance between one of the flow cell carbon tubes and
the Z0VR on the UF preamp board is greater than 2 ohms.
* DIVA: The direct valve is leaking.
* BYVA: The bypass valve is leaking.
* UFM PREAMP BOARD (K14013): IC2, IC5, IC6, IC7, IC8, IC9 or IC10 is
broken.

Some hints of what to do if the error occurs:
Clean the UF cell with a chemical disinfection and calibrate it.

FCN 2.20 035 VFC BUFFER FULL ERROR [F,T,D,S]
Transient error.
Unconditional error if more than three errors during one treatment.

General description of conditions for occuring:
The UF interrupt procedure has filled the VFC data buffer.

Technical description of conditions for occuring:
The UF interrupt timer, timer 5 in IC27 on the CPU board creates
interrupts that the interrupt controller IC79 handles.
Each time an interrupt occurs the procedure FETCH_UF_VFC_VAL is
executed. VFC data is put in a databuffer. It can contain data
from 16 interrupts. The procedure CALC_UF_VFC_VAL is executed
shortly after the interrupt procedure is executed.
If FETCH_UF_VFC_VAL has executed 17 times more than CALC_UF_VFC_VAL,
then the databuffer is full, and this error occurs.

Some possible explanations why the error has occured:
* The UF interrupt timer IC 27, timer 5 on the CPU board (K13017) is
creating too many interrupts. The interrupts should come once a
second. It might be broken or incorrectly initiated.
* The interrupt controller IC 79 on the CPU board (K13020) is broken.
* Software error.

Transient error.
Unconditional error if more than three errors during one treatment.

General description of conditions for occuring:
The program attempted to fetch data in a software VFC buffer
while there was no data to fetch.

Technical description of conditions for occuring:
The UF interrupt timer, timer 5 in IC27 on the CPU board creates
interrupts that the interrupt controller IC79 handles.
Each time an interrupt occurs the procedure FETCH_UF_VFC_VAL is
executed. VFC data is put in a databuffer. It can contain data
from 16 interrupts. The procedure CALC_UF_VFC_VAL is executed
shortly after the interrupt procedure is executed.
If CALC_UF_VFC_VAL attempts to get data from the buffer while
FETCH_UF_VFC_VAL has NOT executed and put any data in the buffer,
then this error occurs.

Some possible explanations why the error has occured:
* Software error.

Automatical safety actions:

General description of conditions for occuring:
A MUX channel software variable has changed its value too often.

Technical description of conditions for occuring:
The UF interrupt timer, timer 5 in IC27 on the CPU board creates
interrupts that the interrupt controller IC79 handles.
Each time an interrupt occurs the procedure FETCH_UF_VFC_VAL is
executed. VFC data is put in a databuffer. It can contain data
from 16 interrupts. The procedure CALC_UF_VFC_VAL is executed
shortly after the interrupt procedure is executed.
The procedure CALC_UF_VFC_VAL has updated the variable MUX$CHANNEL
with data that shall be output on signals UIS0-UIS4 from the outport
IC 48 on the CPU board.
This variable has changed its value more than 8 times during 8

FCN 4.04 001 MM 90 A/D CONVERTER BUFFER POINTER ERROR [F,T,D,S]
Transient error. (No safety action)
Unconditional error if more than three errors during one treatment.

General description of conditions for occuring:
The MM 90 A/D converter interrupt function puts data in a buffer
and incrementes an input pointer. The MM 90 A/D converter function
fetches data from that buffer and increments an output pointer.
One of these pointers had an incorrect value.

Technical description of conditions for occuring:
ALTERNATIVE 1:
The MM 90 A/D converter interrupt function should have
stored A/D converter data in a buffer and should have changed
the value of ADMM_IN_PTR to a value that was not the same as
ADMM_OUT_PTR. The MM 90 A/D converter interrupt routine had not
executed.
The MM 90 A/D converter function FCN 404 detected that
ADMM_OUT_PTR = ADMM_IN_PTR for 10s.
ALTERNATIVE 2:
The MM 90 A/D converter function FCN 404 should all the time give
the variable ADMM_OUT_PTR even values (0,2,4,....)
FCN 404 detected that
ADMM_OUT_PTR was not even.
ALTERNATIVE 3:
The MM 90 A/D converter interrupt routine detected that the MM 90
A/D converter function had fetched too much data from the
A/D converter buffer.
ADMM_OUT_PTR = ADMM_IN_PTR+4
ALTERNATIVE 4:
The MM 90 A/D converter interrupt routine should all the time give
the variable ADMM_IN_PTR values dividable by 4 (0,4,8,....)
The MM 90 A/D converter interrupt routine detected that
ADMM_IN_PTR had a value which was NOT 0,4,8,...

Some possible explanations why the error has occured:
ALTERNATIVE 1:
* The timer IC 2 on the expansion board (K14716) is broken.
* There is a bad connection between the expansion board (K14716) P2
and the CPU board (K13020) P107.
* The CPU IC 89 on the CPU board (K13020) is broken.

FCN 4.04 005 MM 90 FREQ. SELECTION ERROR. [F]
The program can not determine the sampling freq. of the MM90
ad system.
Transient error.

The A/D system identifies which frequency the VFC32 is working with.
The identification procedure begins as soon as the A/D task starts. Thei
frequency selection is always done before the normal work of the A/D
task starts.

The selection procedure uses ten measuring values for offset and
reference values. A mean value is calculated for both offset and ref.
If the mean values are with in the limits the selection is done. If
the mean values are outside the limits the other frequency is chosen.
The procedure is repeated 100 times before an error code is issued.

The limits used by the frequency selection procedure are based on the
following table:

Reference voltage:

Meas freq./ Cap 150 pF 330 pF
max. 4353 1978
38 norm 3660 1663
min. 3134 1424

max. 9577 4353
20 norm 8053 3660
min. 6896 3134

Offset voltage:

Meas freq./ Cap 150 pF 330 pF
max. 2271 1032
38 norm 2024 920
min. 1822 828

max. 4998 2271
20 norm 4453 2024
min. 4008 1822

The limits are for reference voltage max. 4400 and min. 3100 and for
offset voltage 2200 and 1800.

The timer value is selected from the following theory.
The capacitor is changed from 330 pF to 150 pF. According to the data
book for the VFC32 some capacitance is present on the input to the
VFC32. An assumption is made that extra capacitors are present in the
design. The additionally capacitor gives a one-shot capacitor of 150 pF
+ 20 pF. The gate time for the A/D system is then selected to give the
same accuracy as before , 30.25 uV/bit.
