1. INTRODUCTION
This configuration tool allows to configure and to monitor the MVC503R-MB actuator for correct commissioning of the
system. The connection between the computer and the actuator is made via a USB / RS485 converter (LIBO-USB)
with a serial communication bus and ModBus protocol (RTU).
2. INSTALLATION
HARDWARE REQUIREMENTS:
Processor: latest generation
RAM: 2Gbyte
Operating system: Win7, Win10
USB-RS485 serial converter (LIBO-USB)
CONFIGURATOR INSTALLATION PROCEDURE
The software is provided with a self-installing file: "Setup MVC503R-MB Manager".
After the installation, the software is ready for use.
LIBO-USB SERIAL CONVERTER INSTALLATION
LIBO-USB is a USB to RS422 / 485 converter. It supports communication with 2/48 wire RS485;
This device has a removable terminal block for connection to the device and 2 LEDs that indicate the
transmission and reception of data in progress.
To operate in 485 mode it is necessary to set the following DIP-SWITCHES to ON:
1. RS-485 transmission
2. Echo OFF
3. 2-Wire communication
For a Modbus connection with MVC503R-MB, the correct terminals to be used are:
1. TDA (-)
2. TDB (+)
3. GND
The device needs the installation of the drivers either by using the CD-ROM inserted in the box of LIBO-USB or by
downloading the drivers from the network (http://www.bb-elec.com/USOPTL4).

3. SETUP
The software can be started through the icon on the Desktop or through the Start → All path Programs → MVC503R-
MB Configurator → Configurator menu.
4. MAIN WINDOW
When the software is executed, the following window will be displayed:
From the “Language” menu on the top of the window it will be possible select the language Italian or English.
From the menu “Scan”it will be possible to perform a MODBUS scan of the actuators on the network.
From the menu “Configuration File” it will be possible:
To load into the actuator the configuration parameters specified in the selected file (.csv format) only
after the modbus connection is successfully established (“CONNECT” button).

1st issue 10/20 5 DMP116e
To save a configuration file including all the values present into the software interface (values into the
areas: Actuator Configuration, Valve Configuration and modbus parameters (baud rate, parity bit and
stop bit)).
To read from the configuration file the parameters and show them into the software interface.
For the two last functions the Modbus connection with the actuator is not required.
At startup the only selectable Menus are “Language” and “Configuration File”, the “Scan” menu will be enabled
once the “CONNECT” button is clicked and if the connection was successful.
The available functions of the main window are:
Connection to the actuator according the MODBUS configuration parameters (MODBUS
CONFIGURATION box).
Configuration of the actuator (ACTUATOR CONFIGURATION box).
Configuration of the valve characteristic (VALVE CONFIGURATION box)
Positioning of the actuator in the stroke range 0-100% and verify the position (0-100%). (ACTUATOR
COMMAND box)
Verify the operating status of the actuator and possible anomalies (ACTUATOR STATUS box).
5. “MODBUS CONFIGURATION”BOX
In the top left area of the main window, the Modbus communication parameters can be set and verified:
The serial port number (COM Port) which is connected the USB-RS485 converter.
To identify the serial port number connected to the serial converter is necessary to access at the Windows
Control Panel and select “Device Manager”:

1st issue 10/20 6 DMP116e
Select the field “Port (COM e LPT)” and note the serial port number related to the serial converter (in the example
below: COM4).
Modbus address of the device (Modbus Address). Modbus address is selectable via the first 8 dipswitches
of the actuator following the encoding into the technical manual (example to select address 1, the dip switch

1st issue 10/20 7 DMP116e
n°1 has to be positioned on ON).
The modification of the modbus address on the device is only active by switching the actuator off
and on again or pressing the button “RESET” on the manager interface.
Baud Rate (selectable between 9600 and 19200).
Parity Bit (selectable between none, odd and even)
Stop Bit (selectable 1 or 2)
The default communication parameters are: 9600, No parity and 2 stop bit.
Once the previous communication parameters are set, press the CONNECT button and verify if Modbus Status is
OK.
The buttons “READ” and “WRITE” allow to set the Modbus communication parameters (baud-rate, parity and stop bit)
on the actuator MVC503R-MB (slave), while the buttons “GET PARAM.” and “SET PARAM.”allow to set the
communication parameters on the PC side (master).
The parameters set in the Modbus Configuration box are requested only the first time the software and the Serial
converter are used.

In this box it is possible to set the following configuration parameters of the actuator:
Action: it allows to select direct or reverse action.
Calibration: it allows to start the stroke calibration of the actuator;
Press the “READ” button to read the current status, the select from the drop down menu the
label “Learning” and press the button “WRITE”. At the end of the calibration the status Running
will be shown again by pressing the “READ” button .
Failsafe: it allows to select the emergency return position of the actuator selectable between
“Up” or “Down”.
Stroke: it allows to set the fixed stroke mode or the automatic calibration mode;
If the fixed stroke mode is selected, the stroke value has to be set in the Valve Stroke textbox
and it’s necessary to press the “WRITE” button in the “Valve Configuration”box to save it.
Make sure that the other 2 parameters in the section mentioned above are the current ones
otherwise the actuator settings will be overwritten.

stroke, up positioning, down positioning) and the led status on the electronic board.
First power-up: it shows if the actuator has been powered on for the first time.
Up Counter Position: it shows how many times the actuator stem was in the fully retracted position.
Down Counter Position: it shows how many times the actuator stem was in the fully extended position.
Stroke Under 2mm: it shows a calculated actuator stroke anomaly during calibration phase (stroke
below 2mm).
Stroke Over 12mm: it shows a calculated actuator stroke anomaly during calibration phase (stroke
above 12mm).
Low Voltage/Failsafe: it shows the low supply voltage anomaly events as well as the number of
emergency return events.
High Voltage: it shows the high supply voltage anomaly events.
Unexpected Stall: it shows the unexpected stall events, that is how many times a stall has occurred
inside the range stroke.
Extra Stroke: it shows an extra stroke anomaly compared to the calculated stroke during the calibration
phase (stroke out of range).
FW Revision: it shows the actuator firmware version.

1st issue 10/20 11 DMP116e
Reset Actuator: SW reset of the actuator is executed by pressing the “RESET” button . Before to send
others commands to the actuator it is necessary to wait the supercap recharge phase is completed. In case
of changes in the actuator configuration parameters, press the “RESET” button to make the changes
immediately effective.
The parameters in the “Actuator Status” box are read at the connection start-up and every time the label near the
textbox is clicked.

Press the “ENTER” key to send the position command to the actuator.
Feedback: allows to verify the current position of the actuator in the range 0-100%. A value of 110%
indicates that the actuator is in emergency return phase, while a value of 120% indicates that the actuator is
performing the initial position/calibration. The current feedback value is read by the software at the start-up
and cyclically every 1.5sec (it’s possible to read the value clicking on the label “Feedback”). The textbox
“Flow Rate PICV” is N.A.
Flow Rate PICV: in case of “LIBRA” valve selection the percentage of the flow rate valve is shown, while
the textbox “Feedback” shows N.A.
