3 INSTRUCTIONS AND GENERAL OPERATION MODE
When starting up the unit, the ON/OFF key can be pressed to carry out an initial test,
showing all the display's digits and pilots.
The equipment identifier is then displayed:
Then, if the equipment has dead weight (units with weight module or digital cell
communication), the counter value is shown the number of times the unit's metrological
(weight) parameters have been modified.
Finally a message (banner type) describing the different functions of the unit is displayed.
- 10 -
Once complete, the unit again shows the measured weight (weight mode).
3.1 Ordinary weighing (Net/gross tare, tare lock)
By defect, the unit will start up showing the weight on the platform:
Both the text of the banner displayed when st
arting up the unit and the
headers and footers of the tickets can be defined by the user using the
SENSODATA program.
- 11 -
3.1.1 Quick zero:
Whenever, without any weight on the platform, the unit shows a weight value other than
zero.
The zero should be manually corrected by pressing the B key.
3.1.2 Stability
The display shows the measured weight variations. The speed with which the changes and
the degree of weight stability shown are displayed depend on the values set in the filter
parameters. (Options STAB.T, FILTER and FIL.DEP in the Programming Menu).
As soon as the weight stabilises, the display activates the stability pilot ( ) to indicate the
condition of stable weight.
The machine can automatically reset at start
-up
enabling
the
INIT.Z
option
in the WEI.OPT. programming submenu.
- 12 -
3.1.3 Quick tare
Pressing the T key when the unit shows stable weight other than zero causes the unit to
tare the weight on the platform, making the weight value displayed on screen pass to 0 and
activating the pilot NET.
As of this moment, the display shows the net weight whenever the platform weight changes.
Whenever the net weight displayed is not zero, pressing the T key again causes the unit to
carry out a new Tare.
The Quick Tare function it’s only available when the number of divisions of
gross weight is bigger than the one defined in the minim weight option
(WEI.MIN) in the WE.CTR programming submenu.
Most of the actions carried out by the display (print ticket, start load or
discharge, etc.) are associated with stable platform condition.
Most of the actions carr
ied out by the display (tare, print ticket, start load
or discharge of dose, etc.) are associated with stable platform condition
(stable weight).
- 13 -
3.1.4 Gross weight/net weight:
With the unit tared, pressing the B key allows switching between net weight and gross
weight on the display.
To indicate that the weight shown on the display corresponds to gross, enable both the B
pilot and the NET pilot:
Tare is automatically disabled when all the weight is removed from the platform, deleting
and re-displaying the gross weight:
3.1.5 Tare lock
To prevent tare from being disabled when all the weight is removed from the platform, press
the T key a second time when the net weight shown is zero (pressing once tares the weight,
and pressing twice locks tare).
Locking the tare activates the unit's >T< pilot in order to indicate locked tare. As of this
moment, and always when the net weight shown is zero, the T key can switch between tare
and tare locked modes.
- 14 -
3.2 Manual tare
The unit allows a tare value to be defined manually (*). To do this, press the FUN and T
keys at the same time without leaving weight mode. The unit will enter manual tare edit
mode, with the rightmost digit flashing to indicate the tare at this moment. To change the
tare value displayed, use the T key to increase the flashing digit value, the B key to change
digit, the FUN key to cancel and leave without validating, and the ENTER key to validate the
tare value entered, taring the unit whilst locking the Tare.
When a manual tare is active, printing the tare on a ticket will be accompanied by the
symbol "*", indicating that weighing was carried out with a manual tare.
(*)
The manual tare function is NOT available if the limit, traffic light or
any
dose option is enabled (options available through the APPLIC programming
submenu).

3.3 Extended accumulation and totalisation of weighings
The unit can account for weight (accumulate weighings), using the data to print a ticket per
printer and/or label and/or send the weighing data through the serial communication ports
(PORTS).
The unit allows individual weighings (printing a ticket for each weighing) or multiple
weighings (with several weighings in the same ticket and finalised with a total) to be done
automatically (when detecting stable weight on the platform) or manually (by pressing the
INTRO key when the unit displays stable weight).
Three conditions must be met in order for the unit to account for a weight (carry out
weighing): there must be stable weight, which exceeds the value defined as minimum
weighing (*), with the weight dropping below the minimum weight necessary to carry out
weighing at some point since last weighing (i.e. the last weighing has been discharged).
Pressing the key
3.3.1 Manual accumulation
In order to carry out manual accumulation, press the ENT key when the unit shows a stable
weight value above the value defined as minimum weighing.
The following example assumes a stable weight of 1,754 kg, which we have previously
tared manually at 1,538 kg. (1754-1538 = 0.216).
Single weighing is selected using the
W.UNIQ.
option in the Functions
menu.
Automatic weighing mode is selected using the AUTOAC option in the
Functions menu.
(*) The minimum weight value for a weighing is determined using the
WEI.MIN option in the unit's Programming menu.
- 16 -
Start manual weighing by pressing the ENT key to display the message:
The unit then briefly displays the number of weighings accumulated so far (in our case, the
first):
And the accumulated weight subtotal (which, in our case, since it is the first weighing,
coincides with the weighing made)
- 17 -
Once weighing is complete, the unit returns to weight mode and displays the weight on the
platform.
If the unit is connected to a printer, and, for example, the code "100350" has been entered
(using the -CODE- option in the functions menu), the following ticket will have been printed:
At the same time, if a PC connection has been configured in any of the serial
communication PORTS with MANUAL send, pressing the T key causes a frame to be sent
with the weight on the platform at this moment.
In order to carry out a new weighing and continue accumulating, remove the weight from the
platform and place the new weight to accumulate on it; wait for the weight to be stable and
then press the ENT key again.
========================================
N.WEIGH. CODE TARE kg NET kg
========================================
1 100350 * 1.538 0.216
If the code
introduced
is 0 (default value when starting up the unit
), nothing
appears in the CODE field of the ticket.
All the unit's serial communication
PORTS can be configured (from the
-COM-programming submenu) to connect to a printer, a labeller, a repeater
or a PC in order to send weights.
- 18 -
3.3.2 Automatic accumulation
Automatic accumulations do not require the INTRO key to be pressed for weighing; the unit
simply has to detect a stable weight value greater than the value defined as minimum
weighing (*) after the last weighing has been discharged.
3.3.3 Totalise
To complete and totalise all weighings in progress, keep the FUN and ENT keys pressed
down at the same time. When doing this, the screen display switches between the total
number of weighings made and the total weight accumulated, returning to weight mode by
pressing any key.
For example, if 4 weighings are carried out with a total weight of 0.632 kg, the unit switches
between the number of weighings
and the total accumulated weight
until any key is pressed and the unit returns to weight mode.
Automatic weighing mode is selected using the AUTOAC option in the
Functions menu.
(*) The minimum weight value for a weighing is determined using the
WEI.MIN option in the unit's WE.CTR. programming submenu.
- 19 -
If the unit is connected to a printer, the ticket will finish, as in the following example:
In this example, the following operations have been carried out in the ticket:
-Code 100350 has been entered.
-A container of 1.538 kg has been tared.
-A weight of 0.216 kg has been entered and accumulated.
- The weight and the container have been removed.
-A weight of 0.252 kg has been entered and accumulated.
-A weight of 0.083 kg has been entered and accumulated.
-A container of 0.252 kg has been tared.
-A weight of 0.081 kg has been entered and accumulated.
-Totalised by pressing FUN+ENT.
3.4 Piece counter
In piece counter mode the unit calculates and displays at all times the number of pieces
resulting from dividing the measured weight and the weight of each piece.
Piece counter mode is enabled by entering the PIECES option in the unit's functions menu.
The unit can carry out and memorise up to
255 weighings before totalising, and
can accumulate a weight total of over 18 trillion weight units (g, kg, tn, lb) and a
Grand Total of over 60,000 weighings.

When leaving the functions menu, the unit returns to weight mode, displaying the measured
weight.
From this moment on, the unit can switch between weight and piece counter modes by
pressing the FUN key.
The unit enables the pilot to indicate that the value shown on screen corresponds
to a number of pieces and not to a weight value.
A sample of the pieces to count is weighed in order for the unit to determine the unit weight
value of each piece;
FUN
- 21 -
this is done by pressing the FUN key until the unit enters edit mode and the display flashes
0.
At this point the number of pieces corresponding to the weighed pieces sample is entered.
To do this, use the T key to increase the value of the flashing digit, the B key to change
digit, the FUN key to cancel editing and leave without saving, and the INTRO key to validate
and save the piece value entered. The unit will very briefly display the calculated unit weight
value.
It will then return to piece counter mode, displaying as of this moment the number of pieces
corresponding to the weight measured in accordance with the unit weight calculated.
- 22 -
3.4.1 Accumulation and totalisation
Accumulation and totalisation in piece counter mode is carried out in the same way as in
ordinary weighing: accumulate by pressing INTRO and totalise using FUN+INT.
The ticket resulting from the operations with pieces has the following format:
This indicates the unit weight of the pieces, the weight and number of the pieces of each
weighing and the total totalised pieces.
Switchi
ng between weight/pieces
(
pressing the
FUN
key
),
will cause the ticket to
close automatically.

3.5 Units with Battery
Whenever the unit is battery-operated and this is below the correct threshold value, the
corresponding LED will come on and the screen will show:
Automatically, the display illumination will be reduced to the minimum and configured to go
off after 5 minutes of non-activity.
As a precaution, if low battery is detected when starting up, the display will not come on,
showing first the aforementioned literals.
3.6 Equipments with DSD memory (Aliby)
DSD equipments with DSD memory record all weighings made in the equipment.
This memory cannot be erased and it can store up to 500,000 weighings thanks to its
capacity. In case the memory is fully occupied, the equipment rewrites the information of the
oldest weighings so that the information relative to the latest 500,000 weighings can always
be recovered.
The information of the memory is organized depending on the number of Ticket to which the
weighing belongs to. Every ticket is made up with the weighings made from the Ticket
opening until its finishing. In the equipments with DSD memory (Aliby), the number of Ticket
is auto-increased with each new finalized ticket, not being able to be modified by the user.
The -DSD- option from the functions menu allows consulting and printing a copy of each
ticket made on the equipment. It displays the number of weighings, the total accumulated
weight and the net weight of any of the ticket weighings. At the same time, it allows making
a copy per printer of the ticket we are consulting.
When accessing the -DSD- option from the functions menu, the equipment requests the
number of ticket displaying by default the last finished ticket, for example:
- 24 -
This ticket number can be modified by pressing T key to increase the value of the flashing
digit, B key to change digit, FUN key to abort and exit the option without validating, and
INTRO key to validate the number displayed.
Once the ticket number has been introduced, the equipment searches on the DSD memory
the relative data to this ticket.
In case it does not find any associated weighing, the following message is displayed:
To exit right after and come back to -DSD- submenu
In case any associated weighing to the ticket is found, the equipment displays the “WAIT”
message to indicate right after the number of weighings made on the ticket.
- 25 -
and the total accumulated weight.
By pressing T and B keys we will be able to move through the various weighings. First of all
the number of weighing is displayed
and afterwards the recorded net weight:
- 26 -
While the total or various recorded values are displayed, by pressing INTRO key the printing
of the ticket copy is initiated at the same time that the flashing message “Print” is displayed
to indicate that a printing is being made.
Finally, FUN key exits the data visualization mode and enables to edit a new Ticket number.
