1. General description
BLM series scales are destined for identical pieces counting and can be used in
store houses control of production and in similar tasks.
Counting pieces function is based on calculation individual mass of detail from
sample weight or keyboard inscribed. cale avails a “learn algorithm” during
calculation and this algorithm is correcting inaccuracy conversion.
cale owns summing register. This register allows to addition or subtraction of
next result and observation current state of this register.
cales grant claims of regulations abort safeties in European Union, sign
inform about that on brand table CE.
This type of scale not requires legalization.
PKWiU classification: : 33.20.31.

3. Security rules
To avoid electrical shock or damage of the scale or
connected peripheral devices, it is necessary to follow
the security rules below.
• All repairs and necessary regulations can be made by authorised
personnel only.
• To avoid fire risk use a feeder of an appropriate type (supplied with the
scale). Pay attention that supply voltage is compatible with specified
technical data.
• Do not use the scale when its cover is opened.
• Do not use the scale in explosive conditions.
• Do not use the scale in high humidity.
• If the scale seems not to operate properly, unplug it from the mains and
do not use until checked by authorised service.
According to legal regulations it if forbidden to
dispose wasted electronic equipment in waste
containers.
• Please return wasted scale to the point of purchase or other company
specialised in recycling of wasted electronic components.

7. Preparation of ork place
Works place of scale should be chosen carefully. This place should be assured
a proper temperature and essential area for attendance. Weight should stand on
stable table.
Violent movements of air, dust, vibrations, violent changes of temperature or
humidity above 90% are inadmissible. cale should be disallow from strong
electromagnetically or magnetically fields.
8. Preparation to ork
1. Take the scale, pan and
feeder out of the package.
It is recommended to keep
the original scale package
in order to transport the
balance safely in future.
2. Place the scale on a
stable ground not affected
by mechanical vibrations
and airflows.
3. Put a carrying pan 2 in
wholes.
4. Put the fish plate pan
1.
5. Level the scale with the
rotating rear legs 6 so that
the air bubble in the
water-level 5 at the back
of the scale is in the
middle.
If scale has been
moved from places with low temperature to places with
upper temperature (for example in winter), please weight on time 4 hours
purpose of acclimatization.

__________________________________________________________________________________________________________________
9. General rules
1. It is advised to check scale indication accuracy before and after series of
measurement using any load with known weight. To check the scale with legal
verification uses a calibration weight with valid calibration certificate. In case
permissible error is exceeded it is advised to contact the nearest service to
calibrate the scale.
2. Weighed sample should be placed in the centre of the pan.
3. The scale is equipped with a tare equal to its range. To tare the scale press
→T← key (left or right). toring a tare value does not extend measuring range,
but only subtracts it from a load placed on a pan. To make weight control
easier and to avoid range overdrawing, the scale is equipped with a load
indicator (graduated in percentages).
4. Weighing result should be read when the indicator " " lights, which
signalizes stabilization of a result.
5. When the scale is not used but it is necessary to be ready to work
immediately, it can be switched off by pressing I/ key. The scale reading
system is then switched off to "standby" mode. To switch the scale on press
I/ key. The scale is immediately ready to operate maximum accuracy (after
self tests).
6. Before each measurement make sure that zero indicator is displayed. If zero
indicator does not displayed or “----“ communicate appears, press →0← key
and wait until zero indication and zero indicator appears
7. The mechanism of scale is a precision devices and susceptible on congestions,
impacts and mechanical shakes.
Do not overload the scale more then 20% of maximum load (Max).
Do not press a pan by hand.
cale should be protected during the transport.

10. Start of ork
Leave the pan empty, plug the feeder to the mains (~230V/50Hz) and plug the
feeder connector to the 12V power socket at the bottom side of the scale.
cale will execute following step:
- test of electronic components,
- display type of scale and version of program,
- zeroing the indication.
After displayed an indication on the main (left) display scale is ready to work.
11. Pieces counting (PCS)
cale enables to count identical pieces, e.g. turnbuckles or buttons
Measurement with single pieces putting on pan:
A measurement is performed in two phases:
- first phase - single piece weight calculation on the basis of defined pieces amount
(default is 10 pieces.),
- second phase – pieces counting
1. Put on pan quantified details sample.
2. Turn a counting by press →
→→
→ PCS+ key.
3. If the quantified sample consists 10 pieces press ENTER (solid line on the
drawing). If amount of detail is other write correct value by using numeric
keys and ENTER (dotted line on the drawing).
4. Number of details has been showed on right display with PCS indicator. A
sample mass has been showed in centered display with APW indicator.
5. Remove ample form pan and put o portion of pieces.
6. Result of calculation is read from right display.

12 OPERATION MANUAL
__________________________________________________________________________________________________________________
Measurement with single pieces removing from pan:
A measurement is performed in two phases:
- first phase - single piece weight calculation on the basic of removed pieces
(default is 10 pieces),
- second phase – recalculating a weighting portion.
1. Put on pan a box with details.
2. Turn a pieces counting by press →
→→
→ PCS-key and confirm by ENTER key.
3. Remove one or more details from the portion.
4. If one detail is removed press ENTER key. If amount of removed is other write
correct value by using numeric keys and ENTER.
5. Number of details has been showed on right display with PCS indicator. A
sample mass has been showed in centered display with APW.
6. Result of calculation is read from right display.

OPERATION MANUAL 13
__________________________________________________________________________________________________________________
Change/write a sample mass by numeric keys:
During a pieces counting (indicator PCS) user can change actual sample mass.
Write a sample mass when a counting process is turn-off initiate a counting
process.
1. Press a →
→→
→ SPW key.
2. Write sample mass by using a numeric keys and ENTER.
3. Number of details has been showed on right display with PCS indicator. A
sample mass has been showed in centered display with APW.
4. Result of calculation is read from right display.
ote:
1. It is advised that single piece weight is not less than one reading unit and
sample weight used in first phase is bigger than 100 reading units.
2. Err-PCS communicate signalizes that a sample was not put on the pan or
single piece weight is less than one reading unit (it is possible to count pieces but
measuring error is bigger).

et a value of threshold causes a turn-on an indicators MIN, OK i MAX, state of
these indicators depends on value on indicator and thresholds.
If the result of details calculation is:
- lower than threshold undEr – scale signalizes MIN,
- between thresholds - scale signalizes OK, and during a pass a threshold scale
turn-on buzzer,
- bigger than threshold OVEr – and during a pass a threshold scale turn-on
buzzer.
ote:
On the first start scale value of thresholds are set to maximum.
During a setting a upper threshold remember that his value can’t be lower that
value of minimum threshold.
12. Summation of measurements series (Σ

The scale is equipped with data library where user can save detail characteristics
(number, single piece mass, default amount of samples and others) in chosen
record number and later when it is needed recall to it.
During scale work, scanner (configuration: prefix 04h, sufixx CR+LF) readout of
detail number causes searching through scale record library and in case of finding
the right record recalling single piece mass and other data.
Record library edition
Longer pressing of ↔

- SPL – default sample quantity,
- PTARE – inserting constant tare value for the detail,
- undEr – lower threshold value,
- OVEr – upper threshold value,
- SAVE – saving settings,
- ErASE – erasing settings,
- out – exit the library (user can also use CLR key).
