System description
Programmability
BM330 is today the most complete and flexible blood mixer offering a complete system for blood
collection and registration to meet the demands of today and in the future for total quality control and
complete traceability.
It’s unique programming capability makes the blood enters free to choose their own strategy for
collection monitoring and later change it according to new global or local regulations or after their own
wishes.

Network connection
BM330 is also prepared to be connected to a local area network (LAN) for transferring registration and
collection data to a central host computer, so called ”On-line registration”.
This will minimize the risk of exchanging blood bags and offers new and improved possibilities to
quickly adapt the succeeding blood analyze in an optimal way.

Flexibility
Since BM330 is powered by a mains adaptor or an internal rechargeable battery with 12 hours capacity
it can also be used in a conventional way, with or without barcode-reader, as stationary as well as
mobile collection units.

Features
Barcode-reader connection
For quickly registration of donor, blood bags, operator etc.

Network connection
Immediate transfer of scanned barcode information together with collected data i.e. volume, flow, time,
alarms and events to a central PC or host computer.

Programmable registration function

The customer can, with a simple setup-program on PC, by his own decision how the registration
function should be, i.e. what kind of information and the sequence to be scanned by the barcode-reader.

Data storage for collection data

There are data storage for 100-1000 collections depending on the amount of registration data. Stored
data can later be sent to a computer or be written on a paper. The memory is circular, i.e. when memory
is filled the oldest data will be replaced.

Adjustable alarm levels

Alarm levels for min/max flow and time, clock settings and other adjustments are easily set by setup
menus from keyboard. The settings are stored in a non-volatile memory.

Battery for mobile use

Built in rechargeable battery for about 12 hours operation.

BM 330 Operator’s manual

Large display
Large LCD display with 2x20 characters for continues display of set volume, collected volume, flow
and time during collection. The display also shows alarms and guides the operator during the
registration. The text on display can be selected in different languages.

Automatic calibration
Calibration is done automatically by using a calibration weight.

Quick choice of preset volumes

By pressing the ”SET”-button you can quickly and easily choose between two preset collection
volumes.

Accurate volume measuring

The collected blood is measured with a weighing sensor and converted to volume with the factor of
1/1.06 which is the specific gravity for normal blood. The measuring accuracy is better than + 1 %.

Automatic taring
BM330 automatically deducts the weight of the blood bag and anticoagulant solution. All types of
bluebags or set of blood bags can be used.

Homogeneous mixing
The tray is moving in a well-tested seesaw motion to agitate and mix blood and anticoagulant in an
efficient way.

Continues blood flow check

BM330 checks the blood flow continuously during the collection. If the flow is below or exceeds the
set alarm limits, alarm will sound and be shown on display.

Check of collection time

Collection time is checked and if set limit is passed the alarm will sound and be displayed.

Automatic stop
When the predetermined volume of blood has been collected the tube clamp closes automatically and a
ready-signal sounds to inform of the completion of donation sequence.

buzzer to cease.

Calibration. CALIBRATION VOLUME

PRESS START

Make sure the tray is empty and moves freely. Start the calibration by pressing ”START”, after which
zero balancing and taring is done. The display shows:

PUT 450 ML ON TRAY

PRESS SET WHEN READY

Put the reference weight for 450 ml on the tray, (make sure that the reference weight is placed in the
centre of the tray), and press ”SET”.
Note! The reference weight must be 450 ml i.e. 477g. (450x1.06). Reference weights can be ordered
from Ljungberg & Kögel AB.
TARE=102 VOL=441>450
OK PRESS SETUP

The calibration is now performed automatically and the result is shown on display.
The value TARE is the measured tare (dead weight) and should be between 50 and 150. (This value
corresponds to the weight of the scale after automatic zero positioning and is only of technical interest
if there should be any fault during calibration process).
VOL is the read volume and should be close to the referens weight 450 ml. The ratio for 450/(read
volume) gives a conversion factor.
The BM330 microprocessor automatically adjusts the read volume to be 450 ml by multiplying with this
conversion factor and the calibration is done when ”SETUP” is pressed.
If the divergence is to big (more then ±20%) an error message is shown :

TARE=102 VOL=349>450
ERR ADJUST GAIN

Collection without barcode reader registration.

Power on
• Turn on the mixer by setting the switch ON/OFF in ON position. Let the starting sequence proceed as
described in chapter Start-up for automatic check of functions and possible error indications. Check
battery condition when the main menu is shown:

22/3 14:51 BATT=98%

SET=450,CLAMP OPEN

Setting of desired volume

• Two standard volumes can be preset. Selection and change of this volumes can be made in the main
menu.
22/3 14:51 BATT=98%
SET=450,CLAMP OPEN

A press on ”SET” makes the set volume change between the two preset volumes.
With a press on ”+” or ”-” this values can be changed. The set volume starts to blink on display and
further presses on ”+” or ”-” makes the value increase or decrease. If the key is pressed continuously
more then 1 second a rapid change with 10-ml each step will occur. To replace the earlier preset value
the changed settings must be confirmed with a press on ”SET”.

Start of collection.
• Place the blood bag or sets of blood bags on the tray so that the tube inlet of blood bags is upwards
when the tray is in home position.
• Put the tube in the tube clamp and leave at least 25 cm of tube free between the clamp and the tray
allowing the tube to move with no affection to the weighing accuracy.
• Press ”CLAMP” to close the tube clamp. CLAMP CLOSED is shown on display.

22/3 14:51 BATT=98%

SET=450,CLAMP CLOSED
• Perform venipuncture.
• Press ”START” to begin collection. The tray makes a seesaw motion to secure freewheel, tare is
deducted, clamp will open and mixing starts.
Note! Do not touch the scale, tubes or blood bags during taring process since this may cause a faulty
reading of the tare!
Note! If “OBLIGATION SCAN” is set to Yes in the setup menu the collection can not be started before
barcode data has been scanned properly.

The regular menu during collection shows:

VOLUME SET FLOW TIME
123 (450) 57 03:12
VOLUME = current collected volume in ml.
SET = set volume in ml.

13
BM 330 Operator’s manual

FLOW = measured flow in ml/min.

TIME = time in minutes and seconds since start of collection.

Pause during collection.

• In case you have to pause the trays movement during collection, press ”PAUSE AL.OFF”. The tray
will stop in its weighing position, the clamp remains open and the measuring continuous. A press on
”CLAMP” will close the clamp. The display will show:
VOL=234 FL=56 03:35
PAUSE,CLAMP CLOSED

• The mixing will continue again with another press on ”PAUSE AL.OFF” and the clamp will open
automatically if closed.
• In the PAUSE-state the current collection can be interrupted with a press on ”RESET”. To avoid
interruption by mistake it has to be confirmed with an additional press on ”RESET” according to the
menu:
STOP COLLECTION?
YES:RESET NO:SET

Note! An interrupted collection will be registrated as ” collection interrupted”.

Termination of blood collection

• When internal calculations by the microprocessor, based on current flow, shows that next mixing
cycle will imply that remaining volume will be less then 10 ml the trays movement will stop. The
volume is measured continuous and when 1 ml remains the clamp closes.
• A continuous ready signal sounds. The display shows:

VOL=450 FL=0 07:05

READY,CLAMP CLOSED

The sound signal can be silenced with ”PAUSE, AL. OFF”

Note! The mixing continues and the collection time is measured until Pause/Alarm off is pressed.
• Free the tube by pressing ”CLAMP”. The display will show: COLLECTION COMPLETED
PRESS SEND

Note! If “CLAMP” is not pressed within 2 minutes from collection stopped the clamp will open
automatically and the mixer will make one cycle to ensure the blood in the tube is not coagulated. This
will increase the collected blood volume to be more than set volume. This will be repeated every two
minutes until “CLAMP” is pressed.

• Data from the collection are transferred to the registration-PC with a press on ”SEND”. If there is no
registration-PC connected, collection is concluded with a press on ”RESET” instead. The collection
data is stored in the memory and can later be transferred to a registration-PC.
• During the collection all possible errors are also registered. Those can be taring error, motor error,
low battery, flow fail or time fail. More about error handling in the chapter: Alarm- and error
messages,

14
BM 330 Operator’s manual

Note! Collection data are always registered and stored in BM330 irrespective of the fact that using
barcode reader or not. Data can be transferred after each collection or after any number of collections.
When the memory is filled the oldest collection data are overwritten. See chapter ”Send data to PC”.
Note! If something falls on the scale making the set volume reached, the collection can be continued
after removal of the object and pressing “Start” button.

Collection with barcode reader

When barcode reader is used for scanning information concerning the collection, a predefined scanning
sequence has to pass through. The scanning sequence is normally divided in two parts, one before
collection and one after collection. The programming of the scanning sequence is done from a PC with
the use of a windows program, see ”BM330 configuration program, user’s manual”
The collection is done in the same way as chapter ”Collection without barcode reader registration”.
Near the mixer there must be a barcode table with all the necessary barcodes for general functions for
the scanning. This includes the barcode for reverse (undo) in the scanning sequence (REW) and the
barcode to stop repeated questions which has been defined in the configuration.
There must also be the barcodes for scanning additional information for instance if the collected blood
should pass some extra (additional) tests.
The barcode for this program table are written in ”Code 128”-format. The barcode table can be made by
customer or ordered from Ljungberg&Kögel AB.

Registration before collection.

Note! The barcode reader must be selected in the SETUP menus, see chapter ”Setup”.
The scanning sequences starts with a press on ”NEW” and the pre-programmed text strings for the
desired registrations are displayed.
The text strings displayed is guiding the operator through the sequence. In the mixer the barcode
scannings are verified regarding number of characters. When the scanning is correct, ”OK” is shown, a
bleep sounds and the next scanning can be done. Incorrect scanning indicates with the text ”ERR”, 3
bleep sounds and a repeated reading can be done.
Barcode scanning in progress can be interrupted by a press on ”RESET” for return to main menu.
If wrong data is scanned and you wish to erase (undo) the scanned information, just scan the barcode for
reverse (REW).

BM 330 Operator’s manual

Send data to PC
• All stored information can be transferred to the LAN (Local Area Network) after completed
collection by pressing ”SEND”. ”SEND” can also be activated from main menu. Display shows:
DATA TRANSMIT ACTIVE

• Each separate collection is sent in a data batch and the transfer is acknowledged by registration PC.
• When all collection data is sent the display shows:

DATA TRANSMIT READY

• Up to 31 mixers can be connected to the LAN (RS485). When SEND is activated from several
mixers at the same time the transfer will be queued to avoid collision. If transmit is in progress from
one mixer the other waits until the line is free. The display shows:

LINE BUZY WAIT

• If the line is free and a data batch is sent to PC the mixer expects an acknowledgement from the PC.
If no acknowledgement arrives in spite of 3 repetitions an error signal sounds and an error message is
shown:
DATA TRANSMIT ERROR

Note! If transmission by any reason fails the stored data are preserved in memory and will be sent the
next time a transfer is activated.

Alarm and error messages

Low flow and high flow alarm and alarm for exceeding max collection time is announced with a
blinking corresponding text in the main menu and an intermittent sound signal. Other error messages are
shown with a blinking text on the lower row with an intermittent sound signal, two short signals with a
pause. The sound signal is silenced with a press on ”PAUSE AL.OFF”.

Alarm and error messages before and during collection

Battery alarm
If the battery capacity drops below 20% a warning is given with a sound signal and a blinking text :
”BATTERY<20%” . If a collection has started it can be completed but no further collections can be
started without battery recharging. Charge of battery can be done at the same time as collection.

If a battery alarm occur the battery should at once be recharged. If recharging can’t be done the
mixer has to be turned off because deep discharge is shortening the batteries length of life and
storage collection data in memory may get lost.

BM 330 Operator’s manual

Taring error
Automatic tare deduction is always done before collection. If this fails an error message is given with
blinking text and sound. Collection can not proceed. Check that the tray is in its weighing position and
moves freely.

Motor error
If the mixing motor do not start or not find the home-position (weighing position) there is an error
message and collection is stopped. Check that the tray can move freely.

Flow alarm
If the blood flow is below or exceeds the set limits an alarm is given with FLOW blinking in the
collection main menu and an intermittent signal sounds. Flow alarm will be stored in collection data
memory. Flow alarm are prohibited during the first 50 ml of collection because blood flow disturbance
is liable to occur.

Time alarm
If collection time exceeds set time limit, an alarm is activated with TIME blinking on the collection
main menu and an intermittent signal sounds. Time alarm is stored in collection data memory.

Volume=EEE
Indicates overweight, measuring range is exceeded. Check if something is weighing down the tray.

Volume= - - -
Indicates underweight. Measuring range is below limit. The tray has become lighter since tare deduction
(by any reason) or is touching something when it is in the weighing position.

Remaining error messages

Setup error.
When the mixer is powered on all settings and functions are checked. If the setup, stored in non-volatile
memory (EEPROM), has been changed i.e. checksum is not the expected, ”SETUP ERROR” is
displayed and a new setup has to be done. See chapter Setup.

Data error.
Stored data from collections are checked at power on. This data are stored in a memory supplied from
the built in battery and from a backup-capacitor (BUC). If the battery voltage is to low or if it is
disconnected for more than 24 hours there is a risk for lost data. ”DATA ERROR” can be restored by
turning the power off and on again.

Input error.
If the clock is set to an unreasonable value, for instance 31 Feb., this can not be accepted and ”INPUT
ERROR” is indicated.

Clock error.
The clock is repeatedly checked and if there is any fault detected ”CLOCK ERROR” occurs. The fail is
probably restored after a new setting.

Network connection
BM330 mixers can be connected in a LAN to a common registration PC through an USB/RS485 or
RS232/RS485 signal converter. Every individual collection can be transferred without delay to the PC
with the windows program BM330 Information program running for further processing.
The LAN consists of suitable located junction boxes for the mixers wired together with a twisted pair
cable. The mixers connects to this boxes with a 4-parts cable with modular contacts.
See chapter: Technical specification for the cable detail description.

Note! The signal converter shall have galvanic isolation between RS485 line and USB/RS232 line. It is
the person who installs the LAN that is responsible for the installation and that connected external
equipment (converter and PC) comply with relevant safety standard, EN60950, and that the whole
system comply with EN 60601-1-1, ”Safety requirements for medical electrical systems”. If in doubt,
contact qualified technician or Ljungberg&Kögel.

Service and maintenance

Cleaning
BM330 tray, keyboard and cover can be cleaned with a soft cloth and a mild detergent. The tray should
be kept steady during cleaning and no violence must be used in order to keep the weighing accuracy.

Do not use liquids with bleach since this may affect the plastic cover quality and make it fragile.

Calibration (check of weighing accuracy)

The weighing accuracy should be checked regularly e.g. once per month with a reference weight
corresponding to 450 ml (477g). We recommend usage of reference weights from Ljungberg & Kögel
AB.
1. Start-up the mixer and let it warm up for about 5 min. (It takes some minutes for the measuring
circuits to stabilise for highest accuracy).
2. Press the key ”PAUSE ALARM OFF”. Now is a normal taring (zero balancing) done and after this
the mixer is in a continuous weighing position. Check that the VOL value reads 0 ± 1 ml.
3. Put the reference weight 450 ml on the tray and read the result. Note! The reference weight must be
placed in the centre of the tray.
4. If the divergence is to large an adjustment must be done, see chapter ”Setup-Calibration”
5. End calibration with a press on ”RESET”

Notes!
• In this ”continuous weighing mode” the mixer operates like a scale, showing the weight placed on
tray adjusted for the specific gravity of blood ( /1.06).
• If the mixer have been exposed to a big temperature difference, e.g. been moved from a cold
environment to a warm, it must have some time to obtain a stable temperature.

LCD contrast setting

If the display shows weak or unsharp characters the contrast may be adjusted with a little screwdriver
turning the potentiometer inside the plastic cover marked ”LCD CONTRAST”.

Change of battery
When the battery no longer is sufficient for one day collections it has to be changed.
• Turn the mixer off with the switch ON/OFF and pull out the contact from the charger.
• Place the mixer so it supports against the pillars on the backside.
• Unscrew the 2 screws holding the battery hatch.
• Take out the battery and change it to the new one that must be of the same type : Sonnenschein A512
3,5S or of a similar type. Connect the red wire to + and the black to -
• Put the battery back and screw up the hatch.

The battery contains lead and worn out batteries must be left to a recycling station.

Tray parking position

During transportation of BM330 the tray should be placed in horizontal position by pressing ”RESET”
(from the main menu). Repeated press on ”RESET” or power off and on again will cancel the parking
position.

Trouble shooting and actions

When more advanced troubleshooting is needed, down to circuit level, we refer to the technical
documentation with circuit scheme, component placing, parts list, trouble shooting guide etc. which can
be ordered from Ljungberg&Kögel AB.
Ljungberg&Kögel AB also supports technical training for service personnel.
