2 System Description
The IT3000A is a general purpose weighing terminal for use in a variety of applications such as data
logging, data capturing, parts counting and filling. Depending on the chosen scale interface (ADM or
Dual-ADM) and the selected operating mode, either one or two analog understructures with a total of
up to 16 strain gauge loadcells with an impedance of 350 Ω each can be connected.
The operating modes BASIC, COUNT and ONLINE support the connection of 2 scale bases, whereas
TRUCK, TRUCK/ONLINE, CHECK and FILL are intended for 1 scale base only.
As required for a specific application, plug-on modules for 1 or 2 serial interfaces and 1 module with
2 parallel I/Os or 1 analog output can be added. The integrated clock / RAM module (512kB) provides
powerfail safe date and time function, scale error log, and storage for up to 1000,000 records in a
data archive, 99 first weights (operating mode TRUCK), as well as 9 tare values per scale, 9
reference weights (operating mode COUNT) and 9 product parameters (operating mode FILL).
Power supply through the built-in power supply unit is either for 110 - 240 VAC or 12 - 30 VDC.
Cables of all external components are connected at screw terminals.
Weight and additional information is indicated on a back-lit 20-character LCD, height of characters
14mm. Operation and data entry is made via a sealed membrane keyboard with tactile feedback.
Operation, sequence and printout can be configured for a specific application. All entries required for
the configuration can be made through the keyboard of the terminal. As an alternative, a
comprehensive PC program for configuration and archiving is available.
Instead of operating the terminal locally via keyboard and display, full remote control is possible from
a PC. In applications legal for trade data can also be stored in an approved data archive on the PC's
harddisk.
2.1 Construction
IT3000A is incorporated in a stainless steel housing, protected to IP65, for wall-mount or desk-top
installation. As option, a panel-mount version is available. All cable connections are made at the rear
of the housing through tight cable glands.

To connect loadcells without sense lines (4-wire connection), two jump leads each must be
connected at terminal strip KL1 between terminal 1 and 3 as well as 2 and 4 (scale 1 and 2).
For operation with two scales please note:
Connection of 2 scale bases is only supported by the operating modes BASIC, COUNT,
BASIC/COUNT and ONLINE.
The Dual-ADM module has one A/D converter which is either connected to scale 1 or scale 2 and
which does not permit reading of the two scales in parallel (switching mode only). A summing mode
is not possible. On switching from one scale to the other, new measuring values are determined for
digital filtering and the motion detector, thus it takes approx. 1 sec after switching until a stable
weight can be displayed.
The Dual-ADM module provides hardware detection to tell the operating system that now two scales
are connected. Only then the calibration routines for the second scale can be called up.
4.5.4 Connection Cables
For the installation of connection cables for analog weighing platforms please follow the recommendations listed below:
• Only use suitable loadcell cable, (e.g. SysTec order-No. 10KAB211.
4 x 0.75mm² + 2 x 1mm², shielded,)
Nominal voltage of cable ≥250V.
Unsuitable loadcell cable may affect accuracy.
• The shield of the loadcell cable must be connected all around the cable in the cable gland of
the weighing terminal (see also chapter 'Installation' / 'Connection Of Cables'). If an extension
of the loadcell cable is required use only metal junction boxes and cable glands. The shield on
both sides must be connected in the same way as at the terminal. Loadcells and/or weighing
platforms, junction boxes and the terminal must be included in the potential equalization of
the components of a weighing system. Depending on the situation on site this may require
the installation of a separate earth lead of appropriate diameter (e.g. 16mm²) in parallel to the
loadcell cable.
18 Technical Manual IT3000A Rev. 4
• Distance between loadcell cables and power lines: ≥0.5m. Loadcell cables to be installed in
grounded metal conduits, metal hoses or metal cable trays.
• Maximum length of connection cable between weighing platform and IT3000A: 200m
• If tension load is applied to loadcells instead of compression load, connection for +Signal and
–Signal must be switched.
4.5.5 Multiple-Range Scale
Calibration is possible as Single, Dual or Triple Range Scale. The different ranges have different
capacities and scale intervals.
Example: Triple Range Scale with a resolution of 3000 increments for each range:
First range: 0 – 1500kg / 0.5kg
Second range: 0 – 3000kg / 1.0kg
Third range: 0 – 6000kg / 2.0kg
When a Multiple Range Scale is loaded, the scale display changes automatically from a lower to a
higher range. During unloading of the scale, the scale display remains in the higher range. If the scale
was tared (weighing in net mode), on return to gross zero the tare is only cleared when the tare key
is pressed. Only after clearing the tare, the display returns to gross mode and switches back to the
smallest range.
Automatic switching back to the smallest range on reaching zero is only carried out if the scale was
not tared (weighing in gross mode).
Example of a weight curve for loading and unloading a Multiple Range Scale showing the weight and
the displayed scale interval:
Gross Weight/kg
6000
3000
1500
0
Scale Interval/kg:
0.5 1.0 2.0
0.5
t
When the scale is loaded further after it was tared, the tare weight is rounded automatically to the
next scale interval as soon as the display is switched from one range to the next.
The Multiple Range Scale provides weighing of light and heavy loads on the same scale with a high
degree of accuracy, since each range has a resolution -for instance- of 3000d, inexpensive loadcells
can be used.
For the configuration of a Multiple Range scale all ranges and scale intervals can be chosen freely,
however, the maximum resolution of the loadcells (e.g. 3000d) must not be exceeded in any of the
chosen ranges.
Technical Manual IT3000A Rev. 4 19
4.5.6 Multi-Interval Scale
A Single Range Scale can be configured as Multi-Interval Scale with two or three different interval
ranges.
Example for a Triple Interval Scale:
First interval range: 0kg – 1500kg / 0.5kg
Second interval range: 1500kg – 3000kg / 1.0kg
Third interval range: 3000kg – 6000kg / 2.0kg
The scale display changes automatically from one interval range to the next during loading and
unloading of the scale.
Example weight curve for loading and unloading a Multi Interval Scale showing the weight and the
scale interval displayed:
Net Weight/kg
6000
3000
1500
0
Scale Interval/kg:
0.5 1.0 2.0
1.0
0.5
t
After taring the scale, the scale display shows the net weight with the smallest scale interval. Small
weights are shown with the highest accuracy, even when the scale is already loaded to a higher
weighing range. Restriction: The max. permitted manually entered tare weight must not exceed the
weight of the range with the smallest interval.
For the configuration of a Multi-Interval scale all ranges and scale intervals can be chosen freely.
20 Technical Manual IT3000A Rev. 4
4.5.7 Adaptation To Scale Environment
The following parameters can be set to obtain optimum weighing results:
• Motion window size and number of measurments for motion detector
• Filter strength of the digital filter for unstable scales
• Auto Zero Range for Auto Zero Function
• Pushbutton Zero Range for Zero-key
• Power Up Zero Range
• Overload Threshold for display blanking.
4.5.8 Setting Of Geo Value
Before calibrating the scale, the Geo Value must be entered, e.g. Great Britain = 21 (see also chapter
Geo Values). If the scale is calibrated at one location and moved to another location later, it is

4.5.9 Weights & Measures Approved Applications
The highest W&M certified resolution (Scale Capacity / Scale Interval) is 6000 increments (with a
max. of 80% deadload).
W&M approved installations require parameter setting in the group 'Adaptation' as follows:
• Motion Window: 0.5d
• Motion Counter: ≥7
• Auto Zero Range: 0.5d
• Pushbutton Zero: ±2%
• Power Up Zero: ±2% or ±10% *)
• Overload: max. 9 d
*) Depending on the application, also the setting 'Off' may be acceptable, e.g. for hopper
scales.
Under menu item 'W&M Info' the conformity of settings with W&M requirements can be checked.
The scale settings are stored in an EEPROM and secured with the jumper W1 which can be sealed by
Weights & Measures with thread and lead seal to prevent unauthorized modification.

4.6 Serial Interfaces
The serial interfaces of the IT3000A terminal can be configured individually by means of plug-on
driver modules as:
RS232 or RS485 2-wire or RS485 4-wire or RS485 2/4-wire optoisolated or 20mA CL (passive).
By default, the interfaces are assigned to: COM1 → PC/EDP, COM2 → printer. The assignment can
be changed in Service Mode to connect other devices such as remote display and reference scale.

Technical Manual IT3000A Rev. 4 23
4.6.3 RS485 Network
Terminal assignment: Some manufacturers of components with RS485 interface do not refer to the
terminals TX+ and RX+ as 'A', but 'B' instead (correspondingly, the terminals TX- and RX- are not
referred to as 'B', but 'A').
Termination resistors: In order to prevent reflection (baud rate 19200 Baud or higher, and/or cable
longer than 20m) it is recommended to install termination resistors R
cable. The characteristic impedance of the cable should be approx. 150 Ω.
Pull-up / pull-down resistors: When termination resistors are used, also 390 Ω pull-up and pull-down
resistors must be installed at the master (see also following schematic).

For the installation of connection cables for serial interfaces please follow the recommendations listed
below:
• Install data cables to prevent capacitive or inductive interference from other cables, machines
and/or electrical devices that could interrupt data transmission and lead to loss of data. If
fluctuation of the earth potential is experienced, this can cause an equalization current flowing
over the shield. In this case a separate earth lead of appropriate diameter for potential equalization
is required.
• Non-factory made cables must comply with the following specification:
3 times twisted pair plus screen, e.g. LIYCY 3 x 2 x 0.14mm² or LIYCY 3 x 2 x 0.25mm²,
For maximum suppression of interference, shield should be grounded on both sides.

4.10 Mains Connection
Before connecting the instrument to power please note:
• Input voltage of the instrument must comply with local mains supply. Factory setting: 110 - 240
V; 50/60Hz, line cord with safety plug firmly connected. The DC version does not have a line
cord and is intended for connection to 12 V to 30V DC.
• Install mains supply for the instrument separate from supply for machines and equipment
generating noise and/or interference (motors, relays, heatings, etc.). Even short spikes and/or
drop-outs may affect the correct function of the instrument and result in defects. If problems of
that nature are encountered, the installation of a voltage stabilizer or an uninterruptable power
supply unit (UPS) may help to overcome the difficulties.
• IT3000A does not have a mains switch and is operational after connection to the mains supply.
Connection to the mains supply is made via the factory installed line cord (length of cable 2.5m).
Make sure that wall outlet is correctly grounded (not applicable to DC version).
• If the line cord with connector is used as the means to separate the instrument from the mains,
the wall outlet must be installed close to the instrument and must be easily accessible! If a
permanently connected mains cable is used, an easily accessible separator must be included in
the supply circuit!

6.4 Calibration
The zero calibration and maximum load calibration are performed in this group. Instead of calibrating
to maximum load, a calibration with partial load is also possible.
The Geo Value entry permits the calibration at one place even if the scale is to be operated at a
different location. This compensates for the different forces of gravity without recalibration (not for
W&M approved applications). By means of entering the rated signals (mV/V), a scale can also be
precalibrated without test weights (see also chapter 'Precalibration').

6.5 Linearization
Certain weighing inaccuracies are the result of the inherent non-linearity of the load sensor. Up to 6
linearization points can be set freely to compensate this imperfection. Linearization points should be
entered at the points of the weighing curve where the greatest deviations (i.e. max. non-linearity) are
experienced.
Linearization points must be smaller than the max. weighing range. The linearization algorithm
interpretes the sections between two neighboring linearization points as a straight line.

6.10 Calculate Span
When the rated output signal of a scale's loadcell(s) is known, calibration can be made without test
weights. This information is available, for instance, for loadcell types D1, C2 and C3 OIML, for which
test reports are issued by the manufacturer stating the rated output in mV/V.
A prerequisite is that the unloaded scale can be calibrated at zero, which is usually the case.

6.12 Factory Calibration
The calibration parameters of the A/D converter are stored in a powerfail safe EEPROM.
During testing and check out of a weighing terminal, the A/D converter is factory calibrated. I.e.
correction factors (Gain and Offset) are measured by means of precision simulators and stored to
equalize the different amplification values of the individual boards.
When a scale is calibrated, the rated values (mV/V) are measured for Zero (preload) and Load (preload
plus weighing range). Due to the factory pre-calibration (and resulting near-identical amplification),
these rated values can be transferred from one ADM to another one, if there is a need to do so, e.g.
in the event of a breakdown to minimize down time. However, it is strongly recommended to check
the accuracy of the scale with test weights as soon as possible. Recalibration with certified test
weights is mandatory for scales that are subject to Weights & Measures approval.
Entry of rated values is made in Calibration Mode, Group 2, in the steps 'Zero(mV/V)' and
'Load(mV/V)'.

Enter control character to terminate block 3;

Please note (1): In the operating mode 'TRUCK' (and the offline mode of 'TRUCK ONLINE'), the print
cycles for first and second weight (block 1 and 2) are normally terminated with a formfeed, as is
required for printing on weightickets. Test print in block 3 is always made without formfeed. If the
parameter 'Formfeed Char' is set to zero, the transmission of a formfeed character is also omitted in
block 1 and 2, enabling printing on endless paper.
In the operating mode 'BASIC/COUNT' the entered formfeed character is output for all three blocks.
In all other operating modes, the parameter 'Formfeed Char' takes effect only for printing in block 3
(totals).
Hence, formfeed characters are output in the individual operating modes as follows:
BASIC
COUNT
TRUCK
TRUCK ONLINE
BASIC/COUNT
CHECK
FILL
Block 1 — as entered as entered
Block 2 — as entered as entered
Block 3 as entered — as entered
Please note (2): By specifying a special control character the assignment shown above can be
changed as follows:
Control character 'Formfeed Char 127'
The attribute 'S 2 off' is output to terminate printing of each block.
Control character 'Formfeed Char 126'
The attribute 'S 2 off' is output only to terminate printing of block 3. For the other blocks (1 and 2)
no control character is sent.
Example: paper handling for model TMU-295 printer; for this purpose the print attributes S1 and S2
must be entered as follows:
Print attribute ASCII sequence Function
S1 On 27—99—52 no printing without paper
S1 Off —
S2 On —
S2 Off 27—113 release paper
I.e. when control character 127 is specified, the ticket can be removed from the printer after the
printing of each block (and must be inserted and / or positioned for every new printout), while control
character 126 determines that the paper is only released after printout of block 3 is complete. The
print attribute 'S1 On' must be assigned to the first field of a block to activate the paper sensor.

'Online' (see group 'General'), can be supplemented in this way. The position of a field on the
printout is defined by specifying its line and column number. With the PC program IT3000
Configurator, definition of printouts and configuration of sequences are possible in a very convenient
way, but all functions are also accessible via keyboard and display of the weighing terminal (except
for special characters not available on the terminal's keyboard).

*) In the operating mode 'TRUCK', the consecutive-No.2 (4 digits) is increased by 1 with every first
or second weighing (number of weighing). Consecutive-No. 1 (5 digits) is increased by 1 with
every completed second weighing and can thus be used as number of ticket.
In all other operating modes, consecutice-No. 2 is increased by 1 with every weighing in the
cyclic part (block 2). If a total sequence (block 3) is defined, consecutive-No. 2 is reset to 1
again after this block has been carried out. Consecutive-No. 1 (5 digits) is increased by 1 only
after carrying out block 3 (if that is defined).
**) With an ADM scale interface installed, the scale-No. is always 1. When a Dual-ADM board is
used, the scale-No. corresponds to the presently displayed scale (1 or 2). The scale-No. of an
optional reference scale (COUNT) cannot be read.

fields 33 and 34. If a configuration uses the extended capacity of more than 32 fields (44 max.),
the factors 1 and 2 are assigned to fields 45 and 46. This procedure is supported by the IT3000
Configurator as of version 3.01.

With each actuation of the tare key the display is switched from gross to net and back (setting:
'Taremode: Gross/Net'). This is the usual tare function which is appropriate for most applications.
10.2.2 Autoclear Tare
The loaded scale can be tared only once, and the net display is automatically switched back to gross
when the scale returns to the zero range (setting 'Taremode: Auto Clear').
This function must be activated by the operator by pressing the F1 key in the basic step of the
sequence, it is useful for serial weighings with changing tare weight.
W1 25.60 kg
Auto Clear Tare On
The autoclear function can be disabled by pressing the F1 key again, then the scale can only be tared
once and the tare weight remains stored until F1 is pressed to again enable autoclear. This function is

After the start of the sequence, the operator is prompted for the entry of the IDs defined in block 1
(header section), e.g. customer-No. for a delivery note, followed by block 2 (cyclic part) with the
entry of the pertaining IDs, e.g. article-No. Then the weight is captured and data are printed as
defined in block 1 and 2. After block 1 has been carried out once, it is skipped for all following
cycles. The cyclic part can be executed as many times as required. After the last weighing cycle in
block 2 (with printout) and pressing the Total-key the program proceeds to the sequence for block 3
(totals section) to print, for instance, a line with the totals of all transactions. After that the program
returns to the entries in block 1.
This structure provides many options for the configuration of operating sequences with a varying
level of complexity. A simple data logging sequence, for instance, can be configured with block 2
only, while omitting of the other two blocks.
Independently of data entry and printing the two setpoints for the outputs A0 and A1 are monitored
in the background. The two inputs are active in parallel to the keyboard functions:
rising edge E0
rising edge E1
See chapter 'Configuration Examples' for details on how to configure print formats and operating

If parts with widely varying piece weight are to be counted, an additional reference scale can be
connected to capture the piece weight and -if desired- also the number of pieces. The reference scale
is installed as scale W2. The function keys F1 and F2 are used to select the scale in the respective
steps of the sequence.
If a second analog scale is connected via a Dual-ADM module, a serially connected reference scale is
disabled.
Piece Weight Optimization
If the system is configured with one scale only, the program automatically optimizes the average
piece weight. That makes it possible to start with a small number of counted reference parts, then
add -or remove- more parts (which need not be counted). This ensures maximum accuracy for the
subsequent counting cycle.

Serial weighing
The function 'serial weighing' can be selected in Supervisor Mode, this parameter is used to
determine whether the average piece weight is to be stored for the next cycle or whether it is cleared
and must be calculated anew.
In this serial mode it is also possible to configure autotaring and automatic continuation of sequence
after exceeding an adjustable weight threshold. For this mechanism the threshold must be entered as
S1 in Supervisor Mode.
When load is removed from the scale, the weight must first fall below the threshold and then it must
exceed the threshold again when the scale is loaded with the next empty container. For S1 = 0, this
function is disabled.
Technical Manual IT3000A Rev. 4 77
Data entry and printing
If input fields are defined in the header section and the cyclic part, these inputs are prompted after
the number of parts has been calculated for the first time. Then the fields in blocks 1 and 2 are
printed. With every following cycle only fields in block 2 are entered and printed.
If block 3 for totals is configured, the respective inputs / printout is made after pressing the Totalkey. After completing the printout, the totals are cleared.
The two inputs are active in parallel to the keyboard functions:

taring scale #1
In the steps with the display of weight and counted parts, a comparison of the weight of scale #1
with the value entered for setpoint S2 is running in the background and the output A1 is set
accordingly. The output A0 is not used (S1 is used to set the weight threshold for automatic taring in
serial mode).
The operating mode 'COUNT' supports four different operating modes (with the additional option to
switch from scale #1 to #2 in the respective steps of the sequence):
Count unknown number of pieces in a filled container:
• put filled container on scale
• enter known tare weight of container
• take reference parts out of container (or weigh on reference scale)
• confirm piece weight
• put reference parts back into container, read / print calculated number of parts
• remove container, start new cycle.
For the next cycle the tare weight can be cleared and a new one entered. The next parts count can
be made either with the stored reference weight (serial weighing) or with a newly determined parts
weight (call up with Info-key during serial weighing).
Count specified number of pieces out of a filled container:
• put filled container on scale
• press Tare-key to autotare scale
• take reference parts out of container (or weigh on reference scale)
• confirm piece weight
• take more pieces from container until target reached.
To remove more parts from the same container in a new cycle, the scale is autotared again in the
first step. After that the display shows the number of the parts that are taken from the container.
78 Technical Manual IT3000A Rev. 4
Count pieces into an empty container:
• put empty container on scale
• press Tare-key to autotare scale
• put reference parts into container (or weigh on reference scale)
• confirm piece weight
• add parts until target reached.
For a new cycle to count the same parts, the next container is placed on the scale and autotared.
After that the display shows the number of the parts that are put into the container. If parts are
counted on the platform of the scale without container, the taring step can be skipped.
Serial weighing into empty container with automatic taring:
• put empty container on scale
• press Tare-key to autotare scale
• put reference parts into container (or weigh on reference scale)
• confirm piece weight
• add parts until target reached
• remove container from scale
• put next empty container on scale
• add parts until target reached
• remove container from scale, etc.
For this mode, serial weighing must be enabled in Supervisor Mode and a weight threshold must be
entered for the setpoint S1.
Please note: An additional refererence scale can only be tared at the scale and not via the Tare-key at
the terminal.
When an incline sensor is connected (mobile weighing), external taring via input IN1 is not possible.

Sequence
The operating mode 'TRUCK' covers a typical truck scale application with first and second weighing
and calculation of the difference. The tare function is disabled. The first weight memory has a
capacity of 99 records, which can be accessed via a 2-digit ID.
First weight memory
The first weight memory can be subdivided for the storage of known tare weights (e.g. 10 memories
for the tare weights of the scale operator's own trucks) while the remaining memories can be
dynamically allocated for normal transactions with the capturing of first and second weights.
To enter a weight in the reserved memory, either the truck can be weighed on the scale and its
weight stored (call up with F1-key) or the known weight is entered manually (call up with F2-key).
Records stored in the first weight memory can be looked up, printed and deleted, if required. A
specific memory location can be selected either by pressing the Info- or Enter-key repeatedly, or by
entering the 2-digit ID-number of the memory. The first entered number points to the tens, the
second to the lower digit. All reserved memory locations can be looked up, regardless of whether
they are in use or empty, whereas in the dynamically allocated part of the memory only currently
used records are displayed. If the entered ID points to an empty record, the next occupied one is
displayed, if all following ones are empty, the program returns to its initial step.
Printing
Printout for the first weighing is defined in block 1, whereas configuration for the second weighing is
made in block 2. The consecutive-No. 1 is incremented by 1 with every second weighing and can be
used, for instance, as ticket-No. Therefore it is recommended to use consecutive-No. 1 only in the
print cycle of the second weighing. Consecutive-No. 2 is incremented by 1 with every first and
second weighing and can be used to identify the individual weighings.
Test print
If requested, a test print can be configured in block 3. In this block no formfeed is performed, i.e.
printouts appear on paper line after line. For first and second weight printing, formfeed can be
enabled in group 'interface' of the Service Mode.

The operating mode 'FILL 1' can be used for a simple two-speed filling operation with fast and slow
filling. The target value is entered as input step in the sequence. The two setpoints S1 and S2 are
used for the calculation of the fast / slow setpoint (S1) and the preact for the in-flight compensation
(S2). These values are subtracted from the target value.
or reset
input E1
82 Technical Manual IT3000A Rev. 4
Zero setting / taring
Several taring / zero setting options can be selected. The choice is made in the Supervisor Mode in a
step that appears only if operating mode 'FILL 1' is enabled. Options:
• scale is autotared prior to every filling cycle (net filling);
• scale is set to gross zero prior to every filling cycle (only within zero setting range = Push
Button Zero), filling is started only if zero setting could be carried out successfully;
• filling is started without auto taring or zero setting (gross filling); manual tare is possible in
the start step to enter the tare of not completely emptied or partially filled containers (e.g.
gas bottles). For series weighings this tare weight remains stored until it is cleared or
changed. Please note: the use of manual tare is not appropriate for the other two filling
modes.
Cutoff points
Weight and target are compared as absolute (unsigned) values, so it is possible to fill empty
containers or to withdraw material from filled -or partially filled- ones.
Example: target weight 100.0 kg
fast / slow switching point at 90.0 kg (preact fast = 10 kg)
cut-off slow at 98.8 kg (preact slow = 1.2 kg)
S1 = 10 kg; S2 = 1.2kg (entry in Supervisor Mode)
output A0 on from 0 kg to 90.0 kg;
output A1 on after switching to slow speed, it remains on until 98.8 kg is reached.
The value for S1 must be greater than that of S2. If single-speed filling is to be configured, identical
values are entered for S1 and S2, the filling cycle is then controlled only via output A0.
Exchange of signals
The parallel inputs E0 and E1 can be used as external Start / Interrupt signals.
After the start of a filling cycle with the Enter-key or the input signal E0, the scale is autotared and
filling fast is released via the output A0. When the fast/slow switching point is reached, filling fast is
switched off and filling slow is started (output A1). If the parameter 'Fast=Out0+Out1? =Y' is
chosen in the Service Mode, the signals fast and slow are output simultaneosly for filling with fast
speed (e.g. to control a sliding gate with a two-stage valve).
The running filling cycle can be interrupted at any time by pressing the Enter-Key or setting the input
E1. The cycle can be continued by pressing the Enter-key again or resetting the input E1,
respectively.
After reaching the cut-off point, filling is stopped completely and subsequently -if applicable- the
operator is prompted for the inputs in block 1 and 2 (block 1 only for the first cycle). When printout
and data transmission is completed, the terminal is ready for the next filling cycle.
Data capturing and recording
For data capturing and recording, the net weight and the batch counter (consecutive-No. 2) can be
supplemented with inputs in the header section (block 1) and the cyclic section (block 2). A printout
of totals can be configured in the totals section (block 3).
After pressing the Total-key the current status of batch counter and net total is displayed for
verification. If the Enter-key is pressed now, block 3 is printed and the totals are reset. If instead
display of totals is exited with the Up-key, totals are retained and more filling cycles can be carried
out.

The preact values are subtracted from the target weight to calculate the cutoff points and the
outputs are reset when target minus preact fast or target minus preact slow is reached.
For the filling process the calculating sign of the weight variance is ignored, i.e. either an empty
container can be filled (positive weight variance) or material can be fed out of a filled container
(negative weight variance).
Preact correction
If the automatic trend-sensing preact correction (inflight compensation) is enabled (group 'Parameter'
of the Supervisor Mode), the weighing terminal automatically adjusts the value for preact slow,
depending on the deviation from target of the previous filling cycles. The corrected value is written
into the product file. This value can also be changed manually, e.g. to shorten the learning cycle after
change of raw material. Normally the controller brings the weighing result back into tolerance range
after a maximum of 4 filling cycles.
Tare check
Prior to the start of a filling cycle a tare check can be carried out, i.e. filling is only released when the
tare weight is greater than min. tare and smaller than max. tare. If this is not the case, an error
message ('Tare not ok!') is displayed which must be acknowledged by the operator by pressing the ↵-
key. After rectifying the cause of the problem, a new start signal must be set.
If no value is entered for max. tare, the tare check is disabled, e.g. for extraction of material from a
filled hopper.
Exchange of signals
The parallel inputs E0 and E1 can be used as external Start / Interrupt signals.
After the start of a filling cycle with the Enter-key or the input signal E0, the scale is autotared and
filling fast is released via the output A0. When the fast/slow switching point is reached, filling fast is
switched off and filling slow is started (output A1). If the parameter 'Fast=Out0+Out1? =Y' is
chosen in the Service Mode, the signals fast and slow are output simultaneosly for filling with fast
speed (e.g. to control a sliding gate with a two-stage valve).
The running filling cycle can be interrupted at any time by pressing the Enter-Key or setting the input
E1. The cycle can be continued by pressing the Enter-key again or resetting the input E1,
respectively.
After reaching the cut-off point, filling is stopped completely and the tolerance is checked. If minus
tolerance is detected and jog feeding enabled, filling slow is pulse-wise activated until the tolerance
range is reached. An out-of-tolerance message (plus tolerance or minus tolerance with jog feeding
disabled) must be acknowledged by the operator with the Enter-key. Jog feeding can be interrupted
by pressing the Enter-key or setting the input E1.
After the filling is complete -if applicable- the operator is prompted for the inputs in block 1 and 2
(block 1 only for the first cycle). When printout and data transmission is completed, the terminal is
ready for the next filling cycle.
Data capturing and recording
For data capturing and recording, the net weight and the batch counter (consecutive-No. 2) can be
supplemented with inputs in the header section (block 1) and the cyclic section (block 2). A printout
of totals can be configured in the totals section (block 3).
After pressing the Total-key the current status of batch counter and net total is displayed for
verification. If the Enter-key is pressed now, block 3 is printed and the totals are reset. If instead
display of totals is exited with the Up-key, totals are retained and more filling cycles can be carried
out.

In the operating mode 'CHECK' the weighing terminal operates as a plus/minus check scale,
classifying the weight of the test object in three zones (plus / ok / minus). The minus threshold is
calculated as target value minus value entered for S1, while the plus threshold is target value plus
S2. The output A0 indicates 'Weight ok', whereas A1 is used for the status 'Out of tolerance'. For
data capturing and recording, the header section (block 1) and the cyclic section (block 2) can be
configured. A printout of totals can be specified in the totals section (block 3).
In the appropriate steps of the sequence, the two inputs work in parallel to the keys:

If one of the outputs A0 or A1 (or both) is wired on the input E0, printing is automatically released
(without pressing the Enter-key) after capturing the weight and classifying the test object.
A checkweighing cycle is started when the scale is loaded with more than 10% of target weight and
no-motion is detected. Thereafter the output signal corresponding to the result of the check is set,
and it remains on until the weight falls below the threshold of 10% of target, e.g. the test object is
removed from the scale. Then the output signal is reset and a new cycle can be started.

16.1 Structure Of Data Strings
Each data string from the host computer to the IT3000A at least consists of a 2-character command.
Some strings may contain additional parameters and/or data. The maximum length of a string is 250
characters.
Data string PC → IT3000A:
< Command Parameter Data >
Data strings from the IT3000A to the host at least consist of a 2-digit error code. Depending on the
command string received before, additional data may be included.
Data string IT3000A → PC:
< Error code Data > CR LF
For a list of error codes refer to section 'Key And Error Codes'.

16.3 Read Weights
Important note on operation with one or two scales:
Depending on the hardware configuration, IT3000A either supports 1 scale (ADM) or 2 scales
(Dual-ADM). If only one scale is connected via ADM interface, the scale-No. included in the command
is ignored and the scale-No. returned in the IT3000A data string is always '1'.
If a Dual-ADM board is installed for the connection of two scales, the displayed scale can be selected
with the SS command and the scale-No. included in this command. However, it must be kept in mind
that all other commands, implemented for compatibility reasons, which may also include a scale-No.
(e.g. taring or zero setting) only have an effect on the currently displayed scale and do not perform an
automatic switching function (regardless of the scale-No. included in the command). I.e. if scale 1 is
displayed and scale 2 is to be tared, first scale 2 must be selected with the SS command before it
can subsequently be tared with the TA command.
The scale-No. returned in the response string always corresponds to the number of the presently
displayed scale.
RN Read Weight (no motion)
The RN command reads a settled weight.
If the scale is settled the gross, net and tare weights are returned to the host along with current date
and time and ID-number. If a settled weight cannot be obtained within 6 seconds, the RN command
is aborted and error code <13> is returned instead.
If the RN command could be carried out correctly, the gross, tare and net weight is formatted and
stored for use with subsequent print commands (see PR command).
Note: 'Settled' means that consecutive weight readings do not differ more than specified in the scale
calibration (motion window).

RM Read Weight (in motion)
The RM command returns the weight immediately after receipt, even if the scale is in motion.
The status bytes indicate whether the scale was settled or not.
If the RM command is used, the identification-No. is not increased. The identification-No. in the
response data string is '0'.

16.4 Taring
TA Automatic Tare
The TA command performs automatic taring.
Automatic taring is possible only if scale is settled. If no-motion cannot be detected within 6 seconds,
the command is aborted and error code <15> is returned to the host. If required the host must then
repeat the command.

TM Manual Tare
The TM command is used to tare the scale with a value transferred from the host computer.
The tare value may include a decimal point or comma. The terminal rounds the tare value to the
increment size of the scale. If the tare value exceeds the weighing range of the scale, error code
<15> is returned to the host.
