Installation and Commissioning
The unit can be used only for either 3P4W or 3P3W according to your ordering
option and requirement in your electrical installation.
To install and commission for 3P4W, proceed the following instructions:
1. Push the unit into the panel and mount using the claim provided on it.
2. Connect the auxiliary supply (80V AC to 270V AC) to the terminals marked P
and N.
3. Connect the three phases with the phase sequence being R-Y-B to the
terminals marked U1, U2 and U3 respectively. Make sure that the phases
coming to the unit come through control fuses of 1.0A rating. This will protect
the electronic inside from damage due to severe over voltage or phase faults
in the system.
4. Connect the neutral wire to the terminal marked U4.
5. Connect the two wires from the R-phase CT to the terminal marked M1 and
L1 such that S1 from CT goes to M1.
6. Connect the two wires from the Y-phase CT to the terminals marked M2 and
L2 such that S1 from the CT goes to M2.
7. Connect the two wires from the B-phase CT to the terminals marked M3 and
L3 such that S1 from the CT goes to terminal marked M3.

Operational Details
The Power Meter, TINYPRO6 is a versatile meter, with all the features needed to
implement for a robust electrical load management system. It can be configured to
monitor most electrical parameters and communication needs and, is also achieved
by making field programmable parameters, as possible.
There are basically two modes of operation in TINYPRO6:
1. Programming Mode
2. Run Mode
After supplying power (80 VAC - 270 VAC), the unit displays immediately power
receiving information, TRINITY ESPL on Seven Segment screen and by default, the
display comes into Run Mode such as shown below.
Now, the unit can be operated by using the following keypad provided for both the
Programming Mode and Run Mode such as shown below.
Press key on Run Mode for about five seconds continuously, the unit will
therefore enter into Programming Mode, CT PRIMARY with default value.

Programming Mode
In order to operate for all the field programmable parameters, it is easy for user
interface by pressing the keys such as, , and keys. Once the unit
displays is in CT-PRIMARY, press key to move into the next programmable
parameter, UNIT ADDRESS for RS485 communication.
Setting CT- primary
The CT-primary is settable from 5 to 5000 and, should be set so as to give actual
current values in an electrical installation.
To set the CT-primary, proceed the following instruction:
1. Press key for about 4 to 5 seconds on Run Mode display.
2. The unit will alter into Programming Mode display with settable parameter,
CT-primary such as shown below.
3. Press key. Immediately, P starts blinking with an interval of one second
which shows that the parameter is now settable. Set the CT-primary by using
and keys until the desired value is received and then press key
to confirm the set value.
4. Now, the unit will reset and return into Run Mode.
Setting a unit address for RS485 port
The unit has the provision to specify a meter address at site for RS485 port. This
address can be set starting from 1 to 255 with a fixed baud rate of 9600.

To set the CT-primary, proceed the following instruction:
1. Press key for about 4 to 5 seconds on Run Mode display.
2. The unit will alter into Programming Mode display with the settable parameter,
unit ADDRESS such as shown below.
3. Press key. Immediately, P starts blinking with an interval of one second
which shows that the parameter is now settable. Set the ADDRESS by using
and keys until the desired value is received and then, press key
to confirm the set value.
4. Now, the unit will reset and return into Run Mode.

Run Mode
In the run mode, the various parameters calculated by the TINYPRO6 are displayed
on different pages on a three lines of 0.4” Red Seven Segment. There are ten
parameters which displays in different pages with the system values. Now the
displays can be altered and analyzed one by one.
Run Mode Displays
The Run mode displays will autoscroll by default and stay for each page with an
interval of 7 to 8 seconds.
Page 1
The LED indicator glows on VOLT which shows individual phase to phase voltage
of R-Y-B on first row, second row and third row display respectively.
Page 2
The LED indicator glows on AMPS with respect to L1, L2 and L3 which shows
individual phase current values of R-Y-B on first row, second row and third row
display respectively.

The LED indicators glow on system PF, Hz and active power (KW) which shows
their values on first row, second row and third row displays respectively.
Page 4
The LED indicator glows on Total Active Energy (KWh) which shows its system
value on display.

Page 5
The LED indicator glows on VOLT with respect to L1, L2 and L3 which shows
individual phase to neutral voltage of R-Y-B on first row, second row and third
row display respectively.
Freezing and unfreezing the displays
The Run Mode Displays enable to freeze and unfreeze by pressing key and the
LED indicator will start blinking which shows that the display is frozen. By pressing S
and Tkeys, the pages can also be changed and analyzed each parameter. To
unfreeze the Run Mode, press key again which will stop blinking the indicator
and change the pages automatically in an interval of seven to eight seconds.

Communication
UNIT CONNECTED TO RS485 PORT
The industrial standard RS-485 communication port option is also available in
TINYPRO6. This option makes it possible for a user to select TINYPRO6 to provide
power and energy information into a variety of existing or new control systems and
communication networks.
Modbus RTU on RS485 Port
In order to download live data for the various system parameters, user can use
RS485 connecting to a SCADA or EMS software. TINYPRO6 supports an RS485 port
with MODBUS-RTU support. The station id for every meter is site selectable, and so
is the baud rate. The data which can be read using MODBUS query # 3 (Read
Holding Registers) is provided in an address map, with the applicable multiplication
factors, vide Appendix.
Communication line parameters: 9600/8/N/1.
The register map is described in Appendix. All addresses are in decimal whose
parameters are unsigned long. If illegal address is sent in query or host, try to read
more than 32 bytes of data in one query except message is generated. The
parameters name, address and multiplication factor are also mentioned.
Reserved values are for future uses which are transmitted as zeroes. Please refer to
the address map for the various parameters in Appendix.

DEFINING MULTIPLICATION FACTOR
•Hz has a multiplication factor of 100 & not 1000. e.g. If Hz is 48.33, and then it
is sent as 4833.
•For providing resolution, all parameters except PT are multiplied with 100
before transmitting. Thus if the KVA value is 278.99, it is sent out as 27899. PF
has MF of 1000, instead of 100. Thus, a PF value of 0.987 is sent as 987.
•If an attempt is made to read some address other than the valid addresses, the
exception response is sent.
EXPEPTION CODE
In the event that the query from the HOST has no communication error, but there is
some error in specifying the address of registers to be read, the meter returns an
exception message. The format of the exception message will be as under:
Unit Address 0X83 Exception code CRC CRC
Exception Code can have only one value, 02: if the address is not a valid, start
address or host has requested more than 32 bytes of data, this code is returned.
