PRECAUTIONS
READ THIS MANUAL BEFORE using or servicing the instrument.
FOLLOW these instructions carefully.
KEEP this manual for future use.
CAUTION
The purpose of this manual is to make the operator aware of the
texts and explanatory figures, the basic requirements and criteria
for the installation and correct use of the instrument.
Installation, maintenance and repair must carried be out only by
specialized personnel who must have read and understood this ma-
nual. “Specialized personnel” means personnel who, due to training
and professional experience, have been expressly authorized by the
System Safety Manager to perform the installation.
Supply the instrument with voltage whose value is within the limits
specified in the specifications.
It is the user’s responsibility to ensure that the installation complies
with the applicable regulations.
Any attempt to disassemble or modify the instrument not expressly
authorized will invalidate the warranty and relieve Pavone Sistemi
of any responsibility.
The installation and maintenance of this instrument should only be
permitted by qualified personnel.
Pay attention when checking, testing, and adjusting with the instru-
ment turned on.
Make the electrical connections in the absence of the power supply
voltage.
Failure to observe these precautions may result in danger.
DO NOT ALLOW untrained personnel to work, clean, inspect, repair
or tamper with this instrument.

INTRODUCTION
The MCT 1302 is a touch screen weight indicator and batcher to be combined with load cells to meet
the industrial applications.
The instrument is installed in a frame in a slot having a drilling template of 138 x 53 mm and is secured
by means of the 2 tensioning screws supplied.
The MCT 1302 uses the RS232 serial port with ASCII protocols, to be connected to the PC, PLC and re-
mote units with a maximum distance of 15m beyond which it is necessary to use the RS422/RS485 serial
output that allows the connection also with MODBUS RTU protocol up to 32 addressable instruments.
The availability of the most popular field buses, as an alternative to the RS485 port, also allows inter-
facing the instrument with any supervision device currently offered by the market.
A USB 2.0 port is also available and facilitates interfacing with PCs using AN Utility Software available
in the kit.
6 digital inputs and 6 digital outputs configurable by Set-up are always available.
It is also possible to have the analog output in voltage or current even in the presence of the FIELDBUS.
Available versions:
• MCT 1302: weight indicator with RS232 serial output, USB, RS485. The supported protocols are
continuous Modbus RTU.
• MCT 1302/A: version with analog output.
• MCT 1302/PROFINET: weight indicator with RS232, USB and PROFINET serial output.
• MCT 1302/ETHERNET IP: weight indicator with RS232, USB and ETHERNET IP serial output.
• MCT 1302/ETHERCAT: weight indicator with RS232, USB and ETHERCAT serial output.
• MCT 1302/PROFIBUS: weight indicator with RS232, USB and PROFIBUS serial output.
The analog output can also be present with the FIELDBUS option

INSTALLATION
GENERAL INFORMATION
The MCT 1302 is a compact panel mounting instrument made of aluminum.
The instrument is installed in a panel in a slot with a drilling template of 138 x 82 mm and is secured
by means of the 2 tensioning screws supplied.
The MCT 1302 must not be immersed in water, subjected to jets of water and cleaned or washed with
solvents.
Do not expose to heat or direct sunlight.
Do not install the instrument near power equipment (motors, inverters, contactors, etc.) or near devices
that do not comply with CE regulations for electromagnetic compatibility.
The connection cable for the load cells must have a maximum length of 140 m/mm².
The RS232 serial line must have a maximum length of 15 meters (EIA RS-232-C standards).
The warnings given on the connection of the individual peripheral devices must be observed.

ELECTRICAL INSTALLATION
The MCT 1302 instrument uses for the electrical connection of the 3.81 mm removable screw terminal
blocks. The load cell cable must be shielded and channeled away from power cables to avoid elec-
tromagnetic interference.
The field wiring of the instrument must be suitable for the environment in which it will be used
and must comply with all national regulations.
A switch or disconnector must be included in the electrical system.
The switch must be close to the instrument and easily reachable by the operator.
The switch must be marked as a device to stop the machine.
The switch or circuit breaker used as a disconnecting device must comply with the applicable require-
ments of IEC 60947-1 and IEC 60947-3.
WARNING
Disconnect the power supply to the instrument before making electrical connections.
POWER SUPPLY OF THE INSTRUMENT
The instrument is powered through terminals 25 and 26. The power cable must be routed separately
from other cables.
The electric zero (terminal 26) is connected to the metal case. Connect
the terminal 26, in addition to the GND of the power supply, also
on the ground using the screw near the power terminals.
Supply voltage: 18÷30 Vdc, max 5W
