LOAD CELL CONNECTION
The load cell cable must not be routed with other cables, but must follow its own path.
Any cable extension connections must be carefully shielded, respecting the color code and using the
cable of the type supplied by the manufacturer. The extension connections must be made by welding,
or through support terminal blocks or through the junction box supplied separately.
Up to a maximum of 8 350 ohm load cells in parallel can be connected to the instrument. The supply
voltage of the load cells is 5 Vdc and is protected by a temporary short circuit.
The measuring range of the instrument involves the use of load cells with sensitivity up to 3.9 mV/V.
The load cell cable must be connected to terminals 3 to 9. In the case of a 4-wire cell cable, jumper
the terminals 5 to 8 and 6 to 7.
Connect the load cell cable shield to terminal 9.
In case of use of two or more load cells, use appropriate junction boxes (CEM4/C or CSG4/C) of
which the connection is shown below.

LOGIC INPUTS
The logic inputs are insulated from the instrument through optocouplers.
The connection cables of the logic inputs must not be channeled with power cables.
Use a shorter connection cable as possible.
To activate a logic input, it must be brought to the positive of a 24Vdc power supply while
the common item must be connected to its negative. The function of the inputs is established
in the relevant Setup menu.
LOGIC OUTPUTS
The 6 logic outputs are of the Photorelay (dry contact) type with a common item. The capacity of each
contact is 100 mA / 30Vdc. By enabling the output, the contact closes (NA contact).
The environment where the equipment is installed can normally be subject to strong magnetic
fields and electrical noise caused by the machinery present, so it is advisable to implement
the usual precautions in order to avoid that these affect the typical signals of a precision
electronic equipment. (filters on contactor, diodes on 24 Vdc relays, etc.)
The connection of the outputs is shown below

CONNECTION WITH ADDITIONAL INPUTS/OUTPUTS BOARD
In applications where additional inputs/outputs are required, optional I/O boards can be connected
using the dedicated serial connection.
To make the connection, use a shielded cable, taking care to connect the screen to ground at only one
of the two ends. If the cable has more conductors than those used, connect the free wires to the screen.
SERIAL RS232
COMMUNICATION
The serial connection cable must have a maximum length of 15 meters (EIA RS-232-C standards), beyond
which it is necessary to adopt the RS485 interface with which the instrument is equipped.
The cable must not be channeled with other cables (i.e. outputs connected to contactors or
power cables), but must possibly follow its own path.
The PC used for the connection must comply with the EN 60950 standard.
The RS232 serial port is normally used for PC, printer and repeater connections.
To make the serial connection, use a suitable shielded cable, taking care to connect the screen to ground
at only one of the two ends.
The serial connection cable must have a maximum length of 100 meters. The cable must
not be channeled with other cables, but must possibly follow its own path

RS485
Through serial RS485 interface, it is possible to make serial connections for long distances (up to 1000 m).
The RS485 serial connection is of the 2-wire type, and allows to connect up to 32 instruments to a
single MASTER unit (personal computer, PLC, etc.) using a twisted and shielded cable, taking care to
connect the screen to the ground at only one of the two ends.
The cable must not be channeled with other cables (i.e. outputs connected to contactors or power ca-
bles), but must possibly follow its own path.
The PC used for the connection must comply with the EN 60950 standard.
NOTE: If there is a fieldbus, the RS485 is not available.
ANALOG OUTPUT (OPTIONAL)
The instrument provides an opto-insulated analog output in current and/or voltage.
Features:
• Analog voltage output: range from 0 to 10 Volt or from 0 to 5 Volt, minimum load 10K
• Analog current output: range from 0 to 20 mA or from 4 to 20 mA. The maximum load is 300.
To make the connection, use a shielded cable, taking care to connect the screen to ground at only one
of the two ends.
The analog sending can be sensitive to electromagnetic disturbances, it is therefore recommended that
the cables are as short as possible and that they follow their own path.
Warning: do not connect the analog output to active devices.

Page 13
USB DEVICE (SPECIFICATION 2.0 COMPLIANT, FULL-SPEED 12 MBPS)
Use this communication port to directly interface a PC via a USB port.
Use a standard USB cable for the connection.
To connect the instrument via the USB device port, the appropriate driver for the operating system used
must be installed on the PC. For the installation, follow the specific instructions.
FIELDBUS CONNECTIONS
As an alternative to the RS485 serial port, some of the most popular fieldbuses are available. Only
one fieldbus can be used, which must be specified when ordering.

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).

FRONT PANEL OF THE INSTRUMENT
The MCT 1302 is a touch screen instrument dedicated to batching applications.
The main operating characteristics are:
• Programmable recipes, standard - 100 recipes of 20 steps. With Alibi memory option - 1000
recipes with 20 steps.
• 50 programmable activities.
• Management of 38 configurable outputs (6 internal outputs to the instrument plus 8 outputs for each
connected I/O module; maximum 4 modules that can be connected to the instrument). Depending
on the type of activity, up to 2 outputs can be selected.
• Coarse and Fine batching control, tolerance control of the dosed weight and lack of product.
• Automatic repetition of the batching cycles.
• Management of the batched totals by activity and recipe.
The setup parameters are easily accessible and modifiable through the use of the function keys that
from time to time appear on the display used to select, edit, confirm and save the new settings.
DISPLAY
In the operating mode the display shows all the information necessary for a complete control of the
system. According to the various programming procedures, the display is used for programming the
parameters to be entered in the memory, i.e. messages indicating the type of operation being carried
out and therefore helping the operator in the management and programming of the instrument.
POWER UP OF THE INSTRUMENT
When switched on, the display temporarily shows an introductory mask, which shows the firmware
code and the version number. After a few seconds, the main screen is displayed, from which all the
instrument operations can be accessed.

Page 17
MAIN SCREEN
From this screen it is possible to access all the operational and programming functions of the instrument,
following the indicated commands.
Date
The display mode of the main screen can be selected using the appropriate parameter in the “Opera-
ting Mode” menu:
• “Standard” main screen, in which all the quadrants are displayed (weight, recipe selection, cycle
setting, set correction factor setting, batching information).
• Main screen “weight only”, in which only the weight dial is displayed. In this case the weight value
is displayed with a larger size than the standard display. Moreover, in case of batch in progress,
a bargraph is displayed, which represents the net weight batched in relation to the set value.
The “weight only” main screen is activated under the following conditions:
• After 5 seconds from switching on the instrument.
• After 5 seconds from the start of the batch.
To temporarily restore the “standard” main screen, press on the weight value. After 5 seconds the
“weight only” main screen appears again.
