1.2 Safety rules
1. Install on the power supply line a protecting device to avoid short circuits (fuse
or magneto-thermic) according to the specifications.
2. In case of accidental removal of the cover and/or of the connector cover, make
sure that power is disconnected before working on the actuator or near it.
3. The products are maintenance free.
1.3 Overview
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).
2Installation
2.1 Hardware Requirements
•Processor: latest generation
•RAM: 2Gbyte
•Operating system: Win7, Win10
•USB-RS485 serial converter (LIBO-USB)

2.2 Configurator Installation Procedure
The software is provided with a self-installing file: "MVC503R-MB Manager".
After the installation, the software is ready for use.
2.3 LIBO-USB Serial Converter Installation
LIBO-USB is a USB to RS422 / 485 converter. It supports communication with 2/4 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).
2.4 Setup
The software can be started through the icon on the Desktop or through the Start →
All path Programs →MVC503RMB Configurator →Configurator menu.

Figure 1. User interface after the serial converter connection
From the “Settings” menu on the top of the window is possible to select:
•“Read converter parameters”: read the modbus communication parameters of
the converter
•“Write converter parameters”: write the modbus communication parameters
in the converter (the values have to be configured in the comboboxes in the
“Modbus Configuration“ area).
This options allow to set the communication parameters on the PC side (master).
Figure 2. Settings menu
From the “Language” menu on the top of the window it will be possible to change the
language of the Configuration Tool. The selectable languages are: Italian and English.
Figure 3. Language menu
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).
•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).
3.2 Modbus Communication
In the top area of the main window under the drop-down menu, 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”:

•Modbus address of the device (Modbus Address). Modbus address is selectable
via the first 7 dipswitches of the actuator following the encoding into the
technical manual (example to select address 1, the dip switch 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.
•Modbus Status: shows the status of the modbus communication and the
current operation in progress.
•Toggle Button (CONNECTED/DISCONNECTED): allows to connect or disconnect
the serial converter. If the COM port has not been detected this button is not
enable.
