SETTING THE METER : Before putting the instrument in service –
It has to be programmed for CT & PT ratio.
To ensure proper communication, set the correct – •
The unit ID.
•
The Baud rate.
Also ensure the Auxiliary Power Supply (rated 90V – 250V AC/DC).

,DOWN key & the ENTER Key 1) First connect the rated Auxiliary Supply with correct polarity & switch ‘ON’ the instrument. 2 ) P re ss in g t he PR G key, ‘2000’ will be displayed. Press the key to set ‘2006’, which is the password of the unit & common to all the units. 3) N ow Press th e
Key. The unit will display SET CTR . Again press the
KEY to enter the desired CT
primary. Now press the or keys to set the CT primary value. CT primary can be set between 100-2000A in steps of 1A. Once the desired value is displayed, again press the
Key. The unit’s CT
primary is now set. 4) N ow Pre ss the
Key & press the key. . The unit will display SET PT. Again press the
KEY to
enter the desired PT primary. Now press the or keys to set the PT primary value. PT primary can be set between the
11KV-220KV in steps of 1KV. Once the desired value is displayed, again press
Key. The unit’s PT primary is now set.
5 ) O nc e ag ai n pr es s th e key. The unit will display UNIT ID. Press the
Key to enter the desired
unit ID. Now press the or key to set the unit ID. Unit ID can set for any value between 1 to 250. Once the desired value is displayed, again press the
Key. The unit’s ID is now set & the unit
will again display UNIT ID. 6 ) N ex t p re ss in g t he key, the unit will display
‘ BAUD ’ & its default value. Press the
key to enter
the desired baud rate. Now press the or key to set the baud rate. The baud rate can set for any standard values of 19.20, 38.40, or 9600. Once the desired value is displayed, again press the key . The unit’s BAUD is now set & the unit will again display ‘BAUD’. 7) Pre ssi ng t he key, the unit will displays SET RTC. By pressing again press
key unit will display SET HOUR
key it will display default value. . Now press the or key to set hour. Press the
key & Press key it will display SET MINUTE. Again press press the or key to set minute press
key it will display default value. . Now
key. In this way set DATE & TIME to come out of the
RTC setting press PRG key. Normally it is factory set. Again press
key the unit will display SE T

Press
key , ‘2000’ will be displayed. Press the key to set ‘2007’, which is the password
for setting TOD of the unit & common to all the units. Press start time & end time. Press
key it will display SLOT NO. 1 & its
key to select any parameter. By pressing or keys set required
start time & end time. Again press
key & select SLOT NO. 2. by pressing key. Use the same
procedure for setting start & end time of all slots ( SLOT NO 2, SLOT NO 3, SLOT NO 4) 8)
Again press PRG key to come out the TOD setting & press key & select
‘ SAVE ’ option. Press
key to save the set values & quit. If you don’t want to save the values & want to quit without saving, press the key and the unit will display ‘ QUIT’. Press the
key to quit without saving.
9) Now the Instrument is set & ready to put into service. Switch OFF the Power Supply & connect the CT & PT secondary correctly. Switch ON the power supply & the instrument will continuously display the set parameters. 10) The set values are stored in non-volatile memory & are retained indefinitely even in absence of Auxiliary Power Supply.

MODBUS Function DETAILS: The output of ACCORD make Multi-Function Transducer Model MFM-02 is through RS-485 Communication port & uses the MODBUS RTU Protocol. The output can be directly given to a SCADA system or any other Data Acquisition system, operating on the same Protocol. The MODBUS protocol generates the format for the master’s query & places it on the device address as well as on the function code defining the requested action, data to be sent and on the error-checking field. The protocol also constructs the slave’s response message. This message also contains fields confirming the action to be taken, any data that is to be returned, and the error-checking field. If an error occurs in receipt of the message or if the slave is not able to perform the requested action, then the slave will construct an error message and will send it as its response. The interface (connection) between the Data Acquisition system and the transducer is established using twisted pair screened wire & all +ve & -ve terminals are multi-drop connected. Ensure proper earth connection to avoid any possibility of loop currents. Ensure matching of impedances of the termination load and that of the wire at both ends of the line. The maximum length of RS-485 network is limited to 3900 feet (1200 meters) & the maximum number of transducers that can be connected is limited to 31 . The unique addresses of each MFM-02 can be set to any value between 1 and 250. The format for each byte in RTU mode is as follows. Coding system
:
8-bit binary, hexadecimal 0-9, A-F Two hexadecimal characters are contained in each 8-bit field of the message
Function Code
:
03 for read & 06 for write.
Data Format
:
32 bit or 16 bit as mentioned in the table below. Most significant byte first.
E rr or ch ec ki ng fi el d
:
2 by te CR C (c ycl ic al re du nd an cy ch ec k) .
Bits per byte
:
1 start bit 8 data bits 1 parity bit - none 1 stop bit if parity is used & 1 or 2 bits if no parity is used.

Note that all the settings are user configurable, only at the instrument end.
