PA2000-3 Multi-Functional Harmonic Meter User’s Manual
PA2000-3 Multi-Functional Harmonic Meter User’s Manual
the using CT is connected with other instruments,
wiring should be in series mode. Before removal the
current input wire, we must first disconnect CT a
short circuit or secondary circuit. In order to
facilitate the maintenance, we recommend the use of
junction bar.
3. Voltage Input: Standard rated input voltage
should not be higher than the rated input voltage
(100V, 220V or 380V), Otherwise, should consider to
use of PT, voltage input end needs to install the
fuse 1A.
4. Current Input: Standard rated input current
should not be higher than the rated input current
(1A or 5A), maximum is 5A, when it is higher than
5A, should consider using of external CT; before
disconnecting the current input, CT once loop must
be off or strap secondary loop.
3. User must ensure the connected input voltage, 0
current sequences are corresponding and the same.
3.2.2 Auxiliary Power Supply
PA2000 series has a universal (AC / DC) power input
interface,unless with a special note, the series are
provided by the standard AC 220V power supply.The
limit voltage of the products is AC 80-270V, Please
ensure that the power supply applied to the products
in order to prevent damage to the product, In addition,
we recommend:
A: In case it is AC power supply, we propose to install
a 1A fuse at the side of the live wire.
B: When it is in poor quality power grid, it is
proposed to install lightning surge suppressors and
rapid burst suppressor in the power circuit to
prevent from lightning strikes.

3.2.3 Relay Output
PA2000 series features relay output, are used on
various occasions for alarm indication, protective
control output, when digital variables output
effective, relay output turn-on, digital variables
output close and relay output close.
A High Alarm
High alarm means relay output turn-on when the
value is higher than the alarming threshold value.
B Low Alarm
Low alarm means relay output turn-on when the value
is lower than the alarming threshold value.
C Digital Variables Monitoring Alarm
If you choose to switch input as a state of alarm
output, there is no need to set alarm threshold.
During programming operation, relay output is set
as "switch”, when the chosen alarming item is di-1
(for example, d3-1), indicating when this loop
switch is turned on, the relay will output alarming;
when chosen circuit-in item is di-0(for example
d3-0); it means the relay will output alarm when this
loop circuit-in is disconnected.
D Remote Control Relay
If you choose relay output as remote control mode,
through the programming operation to set the relay
output as "remote control", then you can control the
relay output through communication.

resistance) of open-class collector to achieve
active power (forward) and reactive power (forward)
distant transmission, with distant computer
terminals, PLC, DI acquisition module, the
instrument can procure the total pulses so as to
achieve a calculation of the power accumulation. The
power accuracy testing is carried out with a method
of using pulse output (national metering rules: The
pulse error comparison of the standard instrument).

5. Data Communication
PA2000 Multi-Functional Harmonic Meters offer
serial connected half-duplex asynchronous RS485
communication port with MODBUS-RTU protocol.
Various data can be sent over on the communication
lines. A line can connect up to 32 meters for the
same time, and each instrument can set its address
- 45 -
MODBUS-RTU Protocol: MODBUS protocol is a means of
communication connection on a line to response from
the client to the query of the host pc. First of all,
the host pc's signal addresses to the only address
of the terminals (client pc), and then, the client
pc issues a response signal transmitting in the
opposite direction to the host: In a separate
communication line in reverse directions to transmit
the entire data stream (the half-duplex mode).
- 46 -
PA2000-3 Multi-Functional Harmonic Meter User’s Manual
PA2000-3 Multi-Functional Harmonic Meter User’s Manual
MODBUS protocol only allows the communication
between the host (PC, PLC, etc.) and the client
terminals, and does not allow the data exchange among
the independent terminal equipments, thus the
terminal will not occupy the lines of communication
when they are initialized, and they only respond to
the query signal reaching to them.
Host query: The query contains the client address
code, function code, data code, CRC checking code.
The address code is the address of client terminal
which the query reaches to; the function code
instructs the client terminal to carry out the
function which host instructs. For example, function
code 04 demands the client terminal read the register
and return their contents; Data segment contains all
the information which the terminal client will carry
out, for example, in reading instruction, the
information of the data segment contains from which
register to read and the number of the registers to
read. The checking code is to check correctness of
one information; client terminal provides a way to
check the correctness of information under CRC16
checking rule.
Client Response: If the client terminal sends out
a normal response which contains client address code,
functional code, data code and CRC checking code.
The data code includes the data which client captures:
such as the register value or state. If there is a
- 47 -
mistake, the protocol regulates that the client
doesn’t respond to the host computer.
Figure 5-2 Query Response Diagram
Transmission refers to a series of independent data
structure within one data frame as well as the limited
rules for transmitting data. The following is the
definition for compatibility with MODBUS protocol
- RTU mode of transmission. Each frame includes a
start bit, a function bit and 8 data bits, (parity
bit), a stop bit (when not checking) / 2-bit (when
there are checking)

Address Code: The beginning part of the frame
consists of a byte (8 bit binary code), decimal is
0~255, only 1~254 are used in our system while other
addresses are reserved. These bits mark the
addresses of the terminals defined by the users,
The defined terminals will accept the data from the
host connected with them. The address of each
terminal must be unique, only the terminal is
addressed will respond to the query from the host.
When the terminal sends out a response, the client
data response tells the host which terminal is in
communication with it.
Function Code: It shows which functions the client
terminal addressed to carry out. The following table

Data Code: It contains the data for a specific
function which the client terminal carries or the
collected data that the client responds to the host.
The contents of these data may be numerical value,
reference address or the set value. For example: The
function code instructs the client to read a register,
the data code indicates from which register start
and how much data to be read. While the contents of
client returned include the data length and the
relating data.
Check Code: Error checking code (CRC) takes up two
bytes, including 16 bits binary value.CRC value is
calculated by the transmitting device, and then
added to the data frame. While the receiving devices
calculate the CRC value again and compare with the
value in CRC, if the two values are not equal, then
the CRC makes an error.
The flow for generating a CRC is as follows:
1 A pre-register 16-bit 0FFFFH (full-1), as CRC
register.
2. To differ the first 8-bit bytes and calculate with
the low byte of CRC register, the result deposits
back-to CRC register.
3. Move CRC register to the right a bit, to fill the
highest bit as 0 while the lowest bit is moved out
and be detected.

2. Data write (function code: 0x10):
The meters allow customers to write in the setting
data according to Modbus protocol through RS485
interface, the written address data must be settable
address parameters (refer to Appendix III); If the
address is not settable parameters, then the writing
operation is invalid. In order to enhance the
security, reliability, the written data must be with
a password (0x1EC6).

Example for communication text:
1. Reading data (function code: 04):
This feature allows users to access equipment data
collected records and system parameters. A query
data of host can not exceed the defined length by
MODBUS protocol or beyond the scope of the address
defined.
The following example is reading address 1 of a
client terminal reading 3 basic data IA IB IC
collected(each address in data frame takes up 2 words,
the beginning of IA is 262:106 H, the length of the
data is 6: 06H words.)

Communications Data
In the measurements data list, with the exception
of harmonic and the corresponding value of THD
(integer data) and the rest is float data, this float
data is in line with the IEEE-574 data formats:
1 code bit
(S)
8 index code
bits(E7…E0)
23 ending code
bits(p22…p0)
Of which: the ending decimal mantissa is normalized,
the value of the range is 1-2.
S bit is 0, is positive; S bit is 1, is negative
Float value = ( S ) * 2^((E7-E0) - 127) * (1 +
(p22…p0)/2^23);
For example: The collected voltage data Ua =
0x42dd947b
//16-band data
,
Converted into binary data:
01000010110111011001010001111011 //
total of 32-bit
binary,
a
Ep = (10000101)- 127 = 6
Tail = 1 + (10111011001010001111011)/2^23
1.73109376430511474609375
Ua = 2^Ep * Tail = 110.79
=
Harmonic data:
Harmonic data is integer data, divided by 10,000,
is the actual value of the harmonic content
If the second harmonic of Ua02 = 0x0123, collected
through communication
The second harmonic content of voltage Ua is Ua02
= (0x0123)/10000 = 291/10000 = 0.0291 = 2.91%
DA Transmission output data
DA transmission data is integer data, if it is current
transmission, divided by 100,is the actual value
of the transmitting current value, if it is voltage
transmission, divided by 1000, is the actual value
of the voltage output.
Current output transmission:AD1 = (0x334)/100 =
820/100 = 8.20mA;
Voltage output transmission:AD1 = (0x834)/1000 =
2100/1000 = 2.100V;
// The 32-bit break down:
0 // symbol bit, only one bit, 0 is positive number,
1 is plural number

PA2000-3 Multi-Functional Harmonic Meter User’s Manual
PA2000-3 Multi-Functional Harmonic Meter User’s Manual
Voltage’s crest factor voltage and current
percentage is of integer data
, voltage’s crest factor is divided by the 1000 data,
is a real value while the current percentage of the
data is divided by 10,000, is a real value;
+ / PA2000-4B is null and void; please check the
specific features of the 1.4 User Model Selection
List.
Add
Fault setting data and communication setting
calculation:
When the maximum setting voltage is 400.0V, the
writing-in data through the Modbus should be 4000;
when the current setting data is 6.000A, the
writing-in data through the Modbus data should be
the integer 6000; when set value for over-frequency
is 51.00, The writing-in data through Modbus data
through should be 5100; the rest setting data for
faults are the same with the above.
