finder 6M Series Single Phase Modbus Power Monitors
PRODUCT OVERVIEW
6M.Tx family consists of 3 single phase power monitor devices that can be used
in AC and DC systems.
Frequency range for AC systems from 1 to 400 Hz, with nominal current from 50
up to 300 A (Up to 400 A in DC systems).
6M.Tx devices are able to make measurements of Vpk, Ipk, THD(U), etc… which
relate to the quality of the network supply. Measurement data is sent using
Modbus RS485 protocol.
CONNECTION AND WIRING
DEVICE POWER SUPPLY
- – Voltage input terminals for connection to L (or N) of an AC system, or the secondary of a VT (Voltage transformer) if used. Or, for connection to the negative polarity of a DC system.
- – Voltage input terminals for connection to N, (or L) of an AC system, or the secondary of a VT (Voltage transformer) if used. Or, for connection to the positive polarity of a DC system.
- – Terminals for Modbus cable connection. Take care to observe the correct polarity (A+, B-). The cable shield can be connected to the “–“ or GND terminal of the power supply.
- – Terminals for connecting the 6M to either a 12 or 24 V DC power source. To power the device correctly, we recommend using Finder power supplies: Type 78.12.1.230.2400 to power the product at 24 V DC or, Type 78.12.1.230.1200 to power the product at 12 V DC.
Both are 12 W power supplies; the choice should be made according to the power supply voltage required for the other components installed.
If it is necessary to use power supplies with higher power, refer to our catalogue or the website page: https://cdn.findernet.com/app/uploads/S78IT.pdf.
DIP SWITCH SETTINGS
| Default
Address: 1
Baud: 9600| Default setting (1 ON and 2 OFF).
Use this setting to connect the PC to the 6M.Tx using Address
1 and baud rate of 9600 b/s
---|---|---
| Address: 1
Baud: 38400| Use setting 1 ON and 2 ON, to connect the 6M.Tx to a
Modbus Master using Address 1 and transmission speed of
38400 b/s.
---|---|---
| **** Use setting 1 OFF and 2 OFF, to use the 6M.Tx with the parameters set
via software.
To use the set parameters, remove power from the 6M.Tx, move DIP 1 downwards,
and power up the 6M.Tx again.

CONFIGURATION SOFTWAR
IMPORTANT
The configuration software is written in JAVA.
IF NECESSARY, INSTALL THE VERSION OF JAVA 8 0 2510 8 enclosed in the software
folder. To activate the configuration software run the fi le 007_ver131
By clicking on “ACTIONS” at the top left, you can change the language.
CABLE CONNECTION
IMPORTANT:
To proceed with the programming of the 6M.Tx it is necessary to position the
DIP Switches as the fi gure above: 1 ON, 2 OFF. Then switch the device off and
on again by disconnecting and reconnecting the supply voltage.
Press “NEXT” to continue.
This is the default position of the DIP Switches which allows you to reach
6M.Tx with Address: 1 – Baud rate: 9600 bit/s If the DIP Switches are not
positioned as shown in the fi gure, it will not be possible to communicate
with the 6M.T
In this case the communication port is COM3.
If necessary, select the serial port from the drop-down menu and click on
“UPDATE”.
Then start connecting to the device.
4.1LOAD CONFIGURATION FROM FTLE
Allows you to load a confi guration previously created and stored on the PC.
4.2LOAD CONFIGURATION FROM DEVICE
Allows you to read the programming previously memorized on the 6M.Tx: for example, this product was installed in a system which already had 4 other devices installed, so has the address “4” (and has a baud rate of 115200).
Click “NEXT”
SAVE CONFIGURATION TO FILE
This allows you to save the changes made previously or to store a “New confi guration from factory parameters” on the hard disk of your PC.
SAND AND TEST THE CONFIFGURATION OF THE DEVICE
Allows you to send the program to the 6M.Tx and to check its functioning.
NEW CONFIGURATION FROM DEFULT PARAMETERS
Allows you to program the 6M.Tx starting from the factory parameters.
Frequency Calculation by current channel: voltage is typically used to
calculate the frequency, but if this is not possible we can enable frequency
calculation using the current.
Input voltage ratio: We can insert the VT transformation ratio, if a Voltage
Transformer is installed at the voltage input terminals of the device.
Input current ratio: the 6M.Tx can also be used as a simple CT to measure the
current in a system (in which case, connection to the voltage input terminals
is not required).
Filter: selecting 1 you have a faster response speed, selecting 5 you have a
slower response but more accurate reading. The default value is set to 2. For
a more advanced setting it is possible to choose “Custom” in which we can
apply filters in DC as well as in AC Min current threshold (mA): current value
below which 0 mA is read Min power threshold (mW): power value below which 0 W
is read
CONNECTION TO THE DEVICE TO SHOW REAL TIME MEASURES
This allows you to view all the electrical quantities measurable by the 6M.Tx
in real time.
A USB/Modbus RS485 interface must be used as a communication bridge between
the 6M.Tx and the PC.
OFFLINE PROGRAMMING
This allows you to develop a 6M program without it being physically connected
to the PC.
The program will then be saved in a directory on the PC and subsequently sent
to the device when “LOAD CONFIGURATION FROM FILE” is selected.
LOAD CONFIGURATION FROM FILE
Allows you to load and edit a previously created program.
NEW CONFIGURATION FROM DEFAULT PARAMETERS
It allows to create the program starting from the factory data. The program can be only saved on the PC and sent to the 6M only after connection with the USB/Modbus interface.
After the new confi guration, by pressing next, you are asked to “save the confi guration to fi le”. Proceed by storing it in a dedicated directory.
