To connect to the MASTER, use an Ethernet twisted pair cable with the relevant RJ45 connector.

• The RJ45 Ethernet connection cable has a variable maximum length depending on the type of cable.

A common shielded Cat5 cable can have a maximum length of about 180 m.

• It is possible to connect the ethernet communication port directly to the PC, without switching from

other network devices (routers, switches, hubs, lan-bridges or other), but special RJ45 cables, called “crossovers”, must be used.

• Usually the cables are “direct”, and allow the connection to network devices such as routers or hubs,

but not to directly connect two PCs (although currently there are network cards with auto-sensing technology, which recognize the type of cable and the type of connection, allowing direct PC-PC connections even using non-crossover cables).

RECIPE BATCHING SELECTION

JJJ

Press on the recipe dial, in the instrument main screen, to access the active recipe selection screen.

The available recipes are displayed, divided into pages of 4 elements. Press on the recipe line you want to activate. To quickly select an item in the archive, hold down the page change key for a long time, and the recipe index setting screen will be displayed. After setting the index, the page where the required element is present is automatically displayed.

The recipes can also be selected via inputs.

PROGRAMMING THE RECIPE CYCLE NUMBER

From the general screen, it is possible to access the programming of the number of cycles that will be automatically executed following a START batching.

• The number of cycles can be set from 1 to 99; by setting the value 99, the batching cycle is repeated indefinitely until the manual stop by the operator.

• At the end of the programmed cycle sequence, the value of this parameter is automatically reset to 1.

RECIPE CORRECTION FACTOR PROGRAMMING

From the general screen, it is possible to access the recipe correction factor programming.

According to the “Correction Mode” parameter in the “Batching Parameters” menu, the correction factor is managed in the following ways:

• FACTOR - The correction of the recipe is performed by entering a multiplying factor of the setpoints. Parameter programmable from 0.01 to 10.00, which allows you to reduce up to one cent or multiply up to ten times the total weight of the recipe.

• WEIGHT - The correction of the recipe is performed by entering the total weight value that you wish to dose, so the recipe setpoints will be automatically recalculated to obtain the desired total.

Changing the correction value creates the printout of the recipe with the recalculated batching set point, if the “PRINT DOS” parameter is “ON”.

CALIBRATION MENU

MEASUREMENT UNIT

Measurement unit related to the weight value; it appears on the main screen and in all weight parameter settings.

Selectable values: [0] kg, [1] g [2] t [3] lb, [4] N, [5] kN Default: kg

DIVISION VALUE [1101÷1102]*

Value of a single division, expressed in the chosen measurement unit. The relationship between the system’s capacity and the division value constitutes the resolution of the system (number of divisions).

Following the change in the division value, if the system capacity is not changed, the weight calibration is automatically corrected.

Selectable values:

0.0001 - 0.0002 - 0.0005

0.001 - 0.002 - 0.005

0.01 - 0.02 - 0.05

0.1 - 0.2 - 0.5

1 -2 - 5 10 - 20 - 50 Default: 1

(*) The setting of the division values via fieldbus takes place differently from that made by the instrument. Refer to the 1101 and 1102 addresses of the MODBUS register table.

LOAD CELLS CAPACITY [1103-1104]

It defines the value corresponding to the sum of the nominal capacity of the load cells expressed in the selected measurement unit. In the case of systems with only one load cell and “N” fixed supports, enter the value of the cell capacity for the total number of supports. This data constitutes the full scale value of the weighing system. Following the change of the parameter value, the theoretical weight calibration is recalculated.

Values: from 0 to 999999 Default: 0

LOAD CELL SENSITIVITY [1105]

Set the value corresponding to the average sensitivity of the load cells, in mV/V. Values between 0.0 and 4 mV/V are accepted. If no value is programmed, 2 mV/V is assumed.

Following the change of the sensitivity value, the theoretical weight calibration is performed.

Values: from 0.0001 to 4.0000 mV/V Default: 2.0000

Page 42

FULL SCALE [1301-1302]

Values: from 0 to 999999 Default: 0

CALIBRATION TYPE

Selection of the type of calibration. Upon confirmation, one of the following procedures is started.

DEAD WEIGHT CALIBRATION [501 ÷ 503]

Calibration of Zero and Full Scale up to 5 points of linearization with the use of sample weights.

TABLE CALIBRATION [1151 ÷ 1172]

It allows manual programming of up to 5 calibration points. The values correspond to those determined by the linearization procedure with sample weights. In this way, it is possible to copy the calibration values made with sample weights.

Page 43

EXAMPLE OF SETUP/CALIBRATION

By setting the parameters listed above, the theoretical calibration of the full scale of the MCT 1302 is carried out. This procedure must be completed with the zero calibration described below (*page 45). The procedure guarantees, in the absence of mechanical problems, a good accuracy of the system (max. error <1% F.S.).

When the division value selection is changed, the theoretical full scale calibration is automatically recalculated. Selections incompatible with the calibration parameters or with the calibration present in the memory are not accepted.

It is necessary to weigh a tank, with a weight of 750 Kg and with a capacity of 1000 liters, containing a product with a specific weight of 1.3 Kg/dm

whose weight is to be read with a display resolution

of 0.2 kg.

Before proceeding with the setup, make sure that the load cells are connected correctly to the unit and that the tank is empty; you can proceed with the setting of the parameters.

You can use:

#3 load cells capacity 1000 Kg

Sensitivity of 2.0015, 2.0008 and 1.9998 mV/V respectively (average value = 2.0007 mV/V)

Set the following values in the setup parameters:

Measurement unit = kg Division value = 0.2 Load Cell capacity = 3000 Load Cell sensitivity = 2.0007 Full scale = 1500 Dead Weight = 0

Make sure that the value of the signal read in the HARDWARE TEST, LOAD CELLS menu corresponds to the tare weight of the system according to the following proportion:

3000:2.0007=750:X

Where X is the value of the signal expressed in mV/V corresponding to the theoretical value of the weight of the empty tank. The value should be about 0.5 mV/V

(*) At this point, you can proceed to the calibration described in the next paragraph or you can exit the setup menu by saving the data entered.

The instrument should indicate the value corresponding to the weight of the empty tank (for example

756.8).

You can enter the setup menu again and enter the value of the weight read in the “Pretare” parameter and enter the value 756.8

Exit the setup menu again by saving the data.

For greater accuracy, prepare sample weights or pre-weighed material on a certified scale and proceed with the calibration described in the next paragraph.

Page 44

CALIBRATION WITH SAMPLE WEIGHTS

The calibration method described here must be carried out using sample weights and/or product preweighed on a sample scale.

Always perform zero calibration before proceeding with the full scale calibration.

CAUTION! If the instrument is switched off without leaving the set-up menu, the programmed settings are not stored.

If, after calibration, the system has linearity errors, it must be checked that the weighed structure is completely free from mechanical constraints.

OPERATION KEYS DESCRIPTION

Zero calibration: carry out the operation with the scale unloaded but complete with the tare weight, with stabilized weight. The displayed weight must be reset; this operation can be repeated several times.

Calibration with sample weight: before carrying out this operation, load the sample weight on the scale and wait for it to stabilize. The display shows the measured value to be calibrated; set the corresponding weight value via touchscreen. If the set value is higher than the resolution offered by the instrument, the setting is not accepted and the display shows an error message for a few seconds. This operation can be repeated several times.

Activate linearization with sample weights. Up to 5 linearization points on a positive scale can be set. During the linearization phase, in the weight dial the progressive linearization points are displayed (eg "LIN 1") alternating with the current weight.

Press the F.S button to set the value of the sample weight loaded on the scale. To end the procedure, press the LIN button again; it is possible to set a number of points lower than 5.

Exit button from the calibration function.

Page 45

TABLE CALIBRATION

It allows you to manually program up to 5 calibration points, in addition to the zero value. The values correspond to those determined by the linearization procedure with sample weights. In this way, it is possible to display the values determined automatically with this procedure, or modify and program them according to preset values.

SERIAL COMMUNICATION PROTOCOLS

CONTINUOUS ASCII PROTOCOL

The continuous sending is performed at the weight update frequency, compatibly with the serial transmission baud rate. In case of communication on the Ethernet port, the frequency of the continuous transmission is limited to 12.5 Hz.

STX <status> <weight> ETX <chksum> EOT

where: STX (start of text) = 0x02h

ETX (end of text) = 0x03h

EOT (end of transmission) = 0x04.

<status> = character coded as in the following table (bit = 1 if condition is TRUE):

Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0

0 0 1 1

<weight> = field consisting of 8 ASCII characters with the weight value justified on the right without non-significant zeros, with any decimal point and negative sign.

The sent weight value can be the net weight, the gross weight or the peak value, based on the selection of the sent data (MODE parameter) in the setup menu of the serial communication ports (see the relevant paragraph).

In overweight conditions, the field assumes the value: “^^^^^^^^”.

In conditions of weight greater than 99999, the field assumes the value: “_ _ _ _ _ _ _ _”.

In conditions of wrong reading, the field assumes the value: “ O-L ”. <cheksum> = sum of control of string data. It is calculated by executing the exclusive OR (XOR) of all the

characters from STX (or from <Addr>) to ETX excluding the latter; the result of the XOR is decomposed into 2 characters considering separately the 4 upper bits (first character) and the lower 4 bits (second character); the 2 characters obtained are then ASCII coded;

(example: XOR = 5Dh; <csum> = “5Dh”, namely 35h and 44h).

MODBUS RTU PROTOCOL

The addresses listed in the tables follow the standard addressing specified in the reference guide of the Modicom PI-MBUS-300 below that is an extract that helps the user to communicate with the instrument.o.

“All data addresses in Modbus messages are referenced to zero. The first occurrence of a data item is addressed as item number zero. For example:

The coil known as ‘coil 1’ in a programmable controller is addressed as coil 0000 in the data address field of a Modbus message.

Coil 127 decimal is addressed as coil 007E hex (126 decimal). Holding register 40001 is addressed as register 0000 in the data address field of the message. The

function code field already specifies a ‘holding register’ operation. Therefore the ‘4XXXX’ reference is implicit.”

To confirm the entry of a new value in E

prom, execute the MAKE - BACKUP function. If this function is

not run, by turning off the MCT 1302, the value before the change will be restored.

Unless otherwise specified, numerical values (such as addresses, codes and data) are expressed as decimal values.

The MODBUS RTU protocol is only available on COM2 RS485.

HANDLING OF COMMUNICATION ERRORS

The communication strings are controlled by CRC (Cyclical Redundancy Check). In the event of a communication error, the slave does not respond with any string. The master must consider a timeout to receive the response. If it does not get an answer, it must deduce that a communication error has occurred.

HANDLING OF DATA ERRORS RECEIVED

LIST OF HOLDING REGISTERS OF THE MODBUS PROTOCOL

The parameters of the instrument that can be read or programmed through the communication interfaces available on the instrument, according to the hardware setup, are listed in the following table.

The registers of the R type are those readable while those of the W type are those writable.

In the case of the Modbus TCP protocol, the instrument address (“Unit Identifier” field) must always be FFh.

If a fieldbus (different from Modbus) is used, only the R or R/W registers will be present in the input area and only the W or R/W registers will be present in the output area.

The registers have a size of 16 bits.

(*) The instrument parameters managed in the Fieldbus Output Data Area are not changed until this command is sent. When the instrument is switched on, the Output Data Area is completely zeroed, so the Fieldbus master must read the parameter values from the Input Data Area and copy them to the relevant Output Data Area registers, and then it must send the enable command to the Command Register. Otherwise, all the parameters managed in the Output Data Area would be reset at power up.

(***) The instrument is in the setup phase (TRUE flag during access to the SETUP menu of the instrument or during connection with PC software “Optimation”).

READING EXAMPLE

To read the gross weight from the MCT 1302, you must the address 3 to 6 of the Input Area.

To read the net weight, instead, you must read the bytes from 7 to 10 of the Input Area.

If the instrument shows on the display the gross weight value of 12351 in the relative bytes, you shall read:

Byte 3 Byte 4 Byte 5 Byte 6

Hex 00 00 30 3F

OUTPUT DATA AREA

The following table lists the registers of the output area (written by the master and acquired by the instrument), common to all PROFINET, ETHERCAT, ETHERNET / IP fieldbuses.

The registers have a size of 16 bits. The registers written by the master in the output area are read by the instrument at a maximum frequency of 90 Hz (60 Hz in the case of PROFIBUS fieldbus).

The size of the Output area set in the fieldbus master must coincide with the dimension set in the instrument.

WRITING EXAMPLES

To write the Set-up parameters, follow the example below:

In bytes 1-2 (Command Register) write the value HEX 3FFF that opens the internal writing area of the MCT 1302.

Example: You want to change the values of Set-Point 1 and Set-Point 2 to 120 and 9740 respectively.

Set-Point 1 Byte 21 Byte 22

Hex 00 78

Set-Point 2 Byte 23 Byte 24

Hex 26 0C

Save the data by writing the HEX value 7 in the Byte 1-2

N.B. The instrument does not accept writing a value equal to the value already present.

PROBLEM POSSIBLE CAUSE SOLUTION

The display shows the message O-L

The display shows the underscore on the upper display.

The display shows the underscore on the lower display.

The number of decimals is incorrect.

Serial communication does not work correctly.

The semiautomatic zero function does not work.

The semi-automatic tare function does not work.

TROUBLESHOOTING

The weight acquired is not detectable because the load cell is absent or incorrectly connected.

The weight acquired cannot be represented because it exceeds the five figures available or is greater than the capacity of the load cells.

The weight acquired cannot be represented because negative over

-9999. The correct division value was not

selected. The installation was not performed

correctly. The selection of the serial interface operation is incorrect.

The gross weight exceeds the action limit of semiautomatic zero. The weight does not stabilize.

The gross weight is negative or exceeds the maximum capacity value. The weight does not stabilize.

Check the load cell connections.

Select the correct division value in the main menu.

Check the connections as described in the installation manual. Select the settings appropriately.

To restore zero, the weight must be calibrated. Wait for the weight to stabilize or adjust the weight filter parameter.

Check the gross weight. Wait for the weight to stabilize or adjust the weight filter parameter.
