The picture shows how the instrument controls the system adjustment ring.
The MC353 can operate as follows according to its set-up:
FLOW RATE TRANSMITTER
The instrument, thanks to the weight (load cells) and the speed (encoder) signal when it receives the run
input, calculates an instantaneous flow rate which is then transmitted externally through a configurable
analogue output (0÷10 V, 0÷5 V, 0÷20 mA, 4÷20 mA).
It is also possible to receive the following outputs:
- Weight totalization output;
- Conveyed weight preset output;
- Conveyed weight set output;
- Serial communication protocol, Ethernet included.
- Generic alarm output;
- Flow rate equal to 0 output;
- Conveyed weight reset input;
- USB device communication port;
- Optional USB HOST port with USB pen drive interface.
FLOW RATE CONTROLLER
The MC 353 control unit is configured with P.I. (instantaneous flow rate) regulator; it processes the weight
and speed variables to get the instantaneous hourly flow rate and the totalized weight. Furthermore it
acts as flow rate self-regulator.

The external supervisor transmits the work set-up (that can be set also through the keyboard) through
the serial communication to the MC353 control unit; the latter, according to the calculated flow rate
value, controls directly (through analogue output) the inverter frequency of the motor where the weighing
system has been installed.
The MC353 control unit has the following features:
- Weight totalization output;
- Conveyed weight total preset and set output;
- Generic alarm output;
- Flow rate out of tolerance alarm output;
- Flow rate output equal to 0;
- Retroaction analogue output (0÷10V;0÷5V, 0÷20 mA; 4÷20 mA);
- Flow rate proportional optional analogue output;
- Optional analogue input for setting-up the flow rate;
- Inputs for the selection of 15 preset set points;
- Conveyed weight reset input;
- Selection of the instrument state from manual to automatic and vice versa by means of the keyboard,
from the instrument rear side through external contact, and by means of serial communi-
cation protocol;
- Serial communication protocol, Ethernet included;
- Optional USB HOST port with USB pen drive interface.

1.1 - OTHER FUNCTIONS OF MC353
MASTER-SLAVE OPERATION
This instrument can operate as slave, thus acquiring the flow rate setpoint in continuous duty, through
analogue input (0÷10V / 4÷20mA) or digital input (RS485). The flow rate setpoint is updated accor-
ding to the current input: the flow rate setpoint is divided and it represents the input scale end (100%).
In case the current setpoint is set to 0, the setpoint will correspond to the input percentage value of the
system maximum flow rate.
The instrument can also operate as master by transmitting the instantaneous flow rate through the op-
tional analogue output or digital transmission (RS485) for the direct connection to instruments in SLAVE
operation.
PARAMETERS THAT CAN BE SET
It is possible to set the operation parameters through the touch screen user interface; all parameters are
organised on 3 levels with independent access criteria.
All parameters that can be set are listed in a table and clearly identified with a numerical code (address).
The parameters reading and writing access is available on the communication port with supervisor
(Rs422 / RS485 / Ethernet, optional), through the ModBus RTU protocol. Furthermore the parameters
reading and setting can be carried out by sharing files in CSV format on the COM2 communication
port (Rs232 or USB) or directly on USB pen drive connected to the USB Host port (optional).
For operation details see the relevant paragraphs.
DATA IMPORT / EXPORT
To facilitate the data set-up and acquisition in a format that can be used with standard informatic systems
the instrument is provided with files transfer functions (TXT or CSV). It features especially a reading/
writing (even partial) of the memory parameters from CSV files and a data logger procedure to acquire
operation parameters.
To customise the instrument it is possible to set the setpoint names, create Help pages and load the
image displayed upon switching-on (BMP file).
If the instrument is provided with a USB Host option, the import and export of the files mentioned above
can occur directly on USB pen drive.
