Figure 2-8 The transformer AcuRev1300 terminal access type distribution
AcuRev1300 series instrument power supply: ac 100 ~ 415 vac, 50/60 hz, or dc 100300 VDC, can be used throughout the world. Other power supply voltage selection
please contact manufacturers. Instrument in the typical working conditions of power
consumption is very small, so the power supply can by independent power supply, can also
be obtained from circuit under test.Suggested that under the condition of power voltage
uctuation is bigger, use the voltagee stabilizer. Power supply terminals, respectively is: L, N.
The typical auxiliary power wiring is as follows:
12
Page 21
AcuRec1300
Choice of wire of power supply is AWG22-16 or 0.6-1.5mm2.
A fuse (typical 1A/250Vac) or small air circuit breaker should be used in the auxillary
power supply loop. Such as the use of small air circuit breaker, it is recommended to use
IEC947 standards and through the CE certification of products. An isolated transformer
or EMC lter should be used in the control power supply loop if there is a power quality
problem in the power supply.
Note: the power before wiring, please confirm that the current power supply and
instrument brand logo on the power supply voltage is up!
Voltage Input:
Maximum input voltage for the AcuRev1300 series meter shall not exceed
400LN/690LL VAC rms for three phase or 400LN VAC rms for single phase. Voltage input
signal circuit must be installed in the air circuit breaker, fuse or small suggestion with 1 a
fuse.
Potential Transformer (PT) must be used for high voltage systems. Typical secondary
output for PTs shall be 100V or 120V. Please make sure to select an appropriate PT to
maintain the measurement accuracy of the meter. When connecting using the star
configuration wiring method, the PT's primary side rated voltage should be equal to or
close to the phase voltage of the system to utilize the full range of the PT. When connecting
using the delta conguration wiring method, the PT's primary side rated voltage should
be equal to or close to the line voltage of the system. A fuse (typical 1A/250Vac) should be
used in the voltage input loop. The wire for voltage input is AWG16-12 or 1.3-2.0mm2.
AcuRev 1300
13
Page 22
Note: In no circumstance should the secondary of the PT be shorted. The secondary of the
PT should be grounded at one end. Please refer to the wiring diagram section for further
AcuRev 1300
details.
Current Input:
Current Transformers (CTs) are required in most engineering applications. Typical
current rating for the secondary side of the CT shall be 5A (standard) or 1A (Optional),
please refer to the ordering information appendix for further details. CTs must be used
if the system rated current is over 5A. The accuracy of the CT should be better than 0.5%
with rating over 3VA is recommended in order to preserve the meter's accuracy. The wire
between CTs and the meter shall be as short as possible. The length of the wire have an
eect on the accuracy.The wire size of current input is AWG15-10 or 1.5-2.5mm2.
Note: The secondary side of the CT should not be open circuit in any circumstance when
the power is on. There should not be any fuse or switch in the CT loop. One end of the CT
loop should be connected to the ground.
Vn Connection:
Vn is the reference point of the Acuvim II series meter voltage input. Low wire
resistance helps improve the measurement accuracy. Different system wiring modes
require dierent Vn connection methods. Please refer to the wiring diagram section for
more details.

AcuRev1300 communication utilizes RS485 port, via Modbus-RTU protocol. The
wiringterminals are A, B, S. "A" is called dierential signal " ", "B" is called dierentialsignal"-",
"S" is connected to the shielding of shielded twisted pair cable. The maximumdistance of
Shielded Twisted Pair cable is 1200 m. The distance will be shorter if moredevices are on the
same communication link or using a higher baud rate.
If the master device does not have RS485 but RS232 port, a RS232/485 converter can
beutilized. Typical RS485 network topologies include line, circle and star.
In order to improve communication quality, please pay attention to:
1. High-quality Shielded Twisted Pair cable is very important, AWG22 (0.6mm2) or
lower isrecommended. Two cables should be dierent colors.
2. Pay attention to "single point earthing". It means there is only one point of the
shieldingconnected to ground in a single communication link.
3. Every A(+) should be connected to A(+), B(-) to B(-), or it will inuence the network,
evendamage the communication interface.
4. "T" type connection topology should be avoided. This means no new branches
exceptfrom the starting point.
5.Keep communication cables away as much as possible from sources of electrical
noise.When several devices are connected (daisy chain) to the same long communication
line, ananti signalrefecting resistor (typical value 120- 300Ohm, 0.25W) is often used at the
endof the circuit (the last meter of the chain) if the communication quality is distorted.
6. Use RS232/RS485 or USB/RS485 converter with optical isolated output and surge
protection.
7. A infrared port is also available in the Display Module, which supports meterreading.

communication interaction, thus we made PC tools software. This chapter would introduce
some functions with the help of these tools.
Dierent specication of AcuRev 1300 series meters support dierent parameters, you’ll
see the details in the function table. Take AcuRev 1304 for example.
4.1 Parameter settings
AcuRev 1300 series meters need basic settings so that the meters can work in the
scheduled way. The figure below is the display of basic parameters that set by PC tools
software.

2) Energy pulse output
Used to choose the pulse type that represented by the pulse outputted through P1,P2
terminals.
Active: P1,P2 terminals output pulse is active power pulse.
Reactive: the output pulse is reactive power pulse.
3) Demand
Demand supports 4 kinds of calculate methods, which is Sliding block method, xed
block method, rolling block and thermal demand method.
a) Sliding block method: set a 1-30min window time, that is calculate time of demand.
The window slid once per minute, so does the demand value. In this method, in the
operation state demand calculation method is displayed to slip.
b) Fixed block method: set 1-30min as a demand calculate cycle. The whole cycle just
calculate the demand once. Which means the demand update time is equal to the demand
calculate cycle. In this method, in the operation state demand calculation method is
displayed to block.
c) Rolling block method: set 1-30min as a demand calculate cycle and 1 slip time.
Demand cycle must be integrated multiples of slip time. Calculate 1 cycle’s demand at the
end of the slip time. The demand update time is equal to the slip time. In this method, in
the operation state demand calculation method is displayed to slip.
d) Thermal demand method: calculate the demand value through analog the theory
AcuRev 1300
37
Page 46
of the thermal demand table. Set 1-30min as a calculate cycle. In the whole cycle, we just
need to calculate the demand once. Which means the demand update time is equal to the
AcuRev 1300
demand calculate cycle. In this method, in the operation state demand calculation method
is displayed to block.
4) Sealing option
Choose the “meter clock + time of use”, the corresponding content(meter clock, TOU
parameters, Daylight saving time parameters) can be sealed.(the change of corresponding
time must proceed when the seal is open.)
5) Communication permission
Divided into low permission and high permission.
Low permission: important operation (like clear demand event record, programming
event record, open cover event record, meter data, energy data initial energy data)
disabled. But it can update to high permission through updating the communication
permission.
High permission: The communication supports all functions. 30 min after updating to
the high permission, the meter would lower its permission to low permission automatically,
to keep the meter’s safety.
6) Display scan parameters
Users could add data to the display scan parameters through the PC tools software.
The meter would cycling display the elected content.

Electricity and electric parameter data for one side or the secondary side of data
8) Connection mode
According to the actual to select the correct connection mode, otherwise it will lead to the
measurement data is not correct.
9) CT PT set
According to the practical use of set, otherwise, can lead to inaccurate measurement.
10)The pulse constant and pulse width
According to actual use the set, otherwise, can lead to inaccurate pulse output
11)Electricity decimal digits Settings
According to the set, electric energy according to dierent decimal digits, when change
the Settings, may cause the error of electric energy metering.
12)RO output mode
RO output mode can be configured to remote control or alarm output, output can be
congured according to the practical application.

4.2 Basic Measurement Functions
AcuRev 1300
AcuRev 1300 mainly measure the Voltage, Current, Power, Frequency, Power Factor,
demand. Demand supports power demand,current demand and demand prediction
function.Among them, the center line current support calculated value and measured
value of two kinds of algorithms, AcuRev1303 and below model using calculated value;
AcuRev1304 and above model using measurement values, and support the calculation
value of the residual current.
The gure below is the basic measurement parameter display.

support this feature
According to the demand of users, we can depart the time to several sequence time
segments. Each segment can point to the same or dierent rate (at most 4 kinds of rates ).
The meter decides to which rate the current time should belong to according to its inner
clock or communication command. To achieve TOU calculate, it should be calculated
separated in dierent rate.
42
Page 51
TOU calculation can choose inner clock or communication command mode, which
could make the application more exible.

TOU energy time segment setting: at most 14 time blocks.Each block corresponds one
segment table (at most 8 time segment tables). Each segment can point to anyone of the 4
rates.
User can use dierent time block, dierent time segment to full personality demand.
But to make sure the time is valid, the meter would examine the time setting strictly. If it
is correct and has opened the TOU function, the meter would process the TOU calculate
energy. If it is wrong and has opened the TOU function. The energy just cumulated to rate 1.
Time setting demands:
1. Number of time zone setting: after nishing the time zone number setting, the time
zone would be divided according to the number of the time zone. Please attention that the
time zone number should be integers from 1-14. And the time zone format should be open
from small to large.
2. Time zone setting format: xx month-xx date, xx date time list. Only if the time zone
be set according to the closed structure, it considered correct.
3. Date time segment meter's setting: The setting parameters of date time segment
meter are interger from 1-14, after finishing the setting, the date time segment's
parameters in the date time segment meter would be set in a increasing order according to
the date time segment meter's setting.
4. Date time segment setting: the parameter should be integer from 1-14, after the
setting finished, we can set the parameter in the date time segment table according to
the set parameters.Only if the date time zone be set according to the closed structure, it
considered correct.
5. Rate setting: the parameter should be integer from 1-4. It means the maximum that
appeared in the TOU energy. After nishing the setting, it would be rate setting in the time
44
Page 53
segment table. The rate parameter is one of 0,1,2,3(0:sharp; 1:peak; 2:valley; 3:even).
6. Holiday setting: the number of holiday is integer from 0-30, after finishing the
setting, it would be holiday setting, which format is xx month-xx date.
Note: User can customarize the factory settings of time zone segment. When no
asking, the meter would be set as the default factory settings. Users can recover the time
zone segment setting value to the default value through communication.
The use of TOU energy holidays: in the TOU energy parameter setting part, rstly we
should set the number of holidays, then set the demanded holiday in the holiday setting
bar, the format is xx month- xx date. At this time, through setting the meter operate time,
when the meter’s operation time is in the setting time, the energy would increase under
the corresponding rate.
Note: time-division energy is with the highest priority on holidays, when the set of
special date is valid, the measurement of energy would consider the holidays at rst.
Weekly restfunction
The use of TOU energy weekly rest: weekly rest(bit0- Sunday; bit1-bit6: MondaySaturday . when bit is 1, it means weekday, when bit is 0 , it means weekend.) through
setting the clock, when the meter’s clock is under the weekly rest time segments, the
energy would increase under the corresponding rate.
b)The value of the currentrate of self-communication order.
Daylight Saving Time function
Under the DST enable condition, if we choose xed date option, it would change the
DST according to the xed date setting format. The format is month/date/hour/minute/
adjust time(unit:min). if we choose unxed date option, it would change the DST according
to the unxed date setting format.The format is month/ week/which week/hour/minute/
AcuRev 1300
45
Page 54
adjust time(unit: min), according to the above setting format, it would change the DST
automatically.
AcuRev 1300
Through this function, we can achieve the meter’s DST change automatically. When
the clock operates to the DST start setting time, the meter could adjust the clock to some
certain time segment in advance. But when the clock operate to the DST ending, the meter
could adjust the time to some certain time segment pushed back.

Output to the relay: set to 0, alarm occurs, the group is not output from RO.If set to 1,
assuming the M11 module is connected, and M11 RO work mode setting of alarm mode
in the module, alarm occurs, the group output to the RO1, namely RO1 closed, until all the
output to the RO1 alarm RO1 to disconnect after recovery.RO2 ~ RO8 and RO1 principle
is the same.Note: when the relay is used for alarm output only "level" output mode, there
is no "pulse" output mode, the relay output Settings (pulse or level) will be ignored.After
completion of a single event of the functions of setting, the need for the following global,
alarm function can be normal use.
2. The alarm global Settings
The communication address table 700 h to 704 h address global parameters for alarm
correlation.Alarm switch: always determines whether this instrument enable event alarm
function, and is set to "1", to enable the alarm function, related to the alarm Settings to take
eect.
Each alarm channel stop switch: to determine whether the alarm set in each group.As a
16-bit unsigned integer, the bit0 ~ bit11 respectively corresponding to the group 1 to 12
group can set the alarm, the corresponding bit is "1" when the group alarm set to take
eect, otherwise is invalid.
When the alarm events, can be congured RO work mode, make it as an alarm output.
AcuRev1300 support 2 alarm output modes, pulse output mode and the level of output,
respectively, when choosing pulse output mode, you can set the corresponding pulse
width, the range of 50 ~ 3000 ms.And need to congure the various alarm output channel
can make logo, the bit0 ~ bit11 respectively corresponding to the group 1 to 12 groups can
make alarm output, the corresponding bit is "1", the group of alarm events, RO accordingly

3. Alarm record
Available for event alarm record store data buer can store 20 groups of alarm events,
not guarantee a set a record, but with the method of circulation records, the events of
the new record will cover the earliest records.When the limit of alarm parameter back to
normal, normal value and events also referred to as the event log, user access to the limit
of time and return to normal time, you can get the limit the duration of the event.

4.8 Incorrect connection detection
AcuRev 1300
AcuRev1300 series instrument has the function of connection detection, Can be set in
the interface to the function that can, in the case of function can make can automatically
detect instrument according to the instrument connection mode of connection is
correct,its principle is as follows:
1. Lack of phase detection: a phase voltage value is 0, as lack of phase.
2. Voltage phase sequence detection: A phase voltage as the reference point, determine
the voltage phase sequence, such as detected by reverse phase sequence, or could be N
lines to meet the current and voltage and voltage is the voltage and the indirect inverse.
To determine the voltage value, such as a two phase voltage values are with another phase
voltage deviation is too large (0.3 times), was convicted for the phase voltage into the N
wrong; Otherwise the sentence to indirect fault voltage, B, C phase fault.
3. Current detection: A phase voltage as the reference point, read the phase current and
voltage between A phase Angle, to judge whether its value and standard value Φ Angle
deviation within 30 °, if meet the requirements, convicted for the current connection
correct; Between Φ +180° ±30°, jailed for current reverse; Other values for the current phase
sequence error.
Visible, the calibration method is suitable for the situation that voltage current Angle
should not exceed 30 ° (Each phase PF value should be greater than 0.866), and is based
on A phase voltage reference direction, therefore should ensure that A phase voltage
connection correct; As A phase voltage phase or connect with N, the current test results do
not have reference meaning; Like the other two phase with A fault, the test result is correct,
but may lead to inconsistent with system parameters.Such as the meter voltage wiring in
order for B, C, A, wiring in the system in order for A, B, C, will cause A phase data does not
match, need to pay attention to.

This chapter introduced how to use software to manipulate the meter through the
communication interface.This chapter content master needs you with MODBUS protocol
AcuRev 1300
knowledge reserves and read through the content of all the other chapters in this manual,
this product features and applications concept has a more comprehensive understanding.
The chapter’s contents include MODBUS protocol, communication format, application
details of AcuRev 1300 series meter.
5.1 Modbus Protocol Introduction
1. Transmission mode
The mode of transmission denes the data structure within a frame and the rules used
to transmit data.
Coding System 8 bit
Start bit 1 bit
Data bits 8 bit
Parity No parity / odd parity / even parity
Stop bit 1bit or 2bit
Error checking CRC
2. Frame
When data frame reaches the terminal unit, it goes through the unit via a special
"port", theunit removes the data frame's header, reads the data, if there is no error, then
it implements the data's task. Afterwards, the unit puts its own data with the acquired
header, and sends back the frame to the sender. The response data frame contains: Address,
Function, Data and CRC Check. Any error will cause a failure to respond.

2.1 Frame Format
AddressFunctionDataCheck
8-Bits8-BitsN x 8-Bits16-Bits
Table 5-1 Data Frame Format
2.2 Address Field
The address field is at the start of the frame. It is composed of 1 byte (8 bits), its
decimalvalue range is 0-247.
A master addresses a slave by placing the slave address in the address eld of the
message. When the slave sends its response, it places its own address in this address
eldof the response to let the master know which slave is responding.
2.3 Function Field
When a message is sent from a master to a slave device the function code eld tells
theslave what kind of action to perform.

2.4 Data Field
AcuRev 1300
Data field contains the data that terminals need to complete the request and the
63
Page 72
data that terminals respond to the request. This data may be a numerical value, address or
setting. For example, Function Code tells the terminal to read one register, Data Field needs
AcuRev 1300
to specify reading from which register and how many registers to read.
2.5 Error Check Field
The eld allows the error check by master and slave devices. Due to electrical noise
andother interferences, a group of data may be changed while transmitting from one
location to the other. Error Check ensures master or slave devices do not respond to the
distorted data during the transmission, which enhances the system security and eciency.
Error Check uses 16-bit Cyclic Redundancy Check (CRC 16).
3. CRC Check
Every message includes an error checking field which is based on the Cyclical
Redundancy Check (CRC) method. The CRC eld checks the contents of the entire message.
It isapplied regardless of any parity check method used for the individual characters of the
message. The CRC eld is two bytes long, containing a 16-bit binary value. The CRC valueis
calculated by the transmitting device, and is appended to the message.
The receiving device recalculates the CRC value during reception of the message, and
compares the calculated value to the actual value it received in the CRC eld.
An error will be reported if the two values are not equal. CRC calculation is first
started by preloading the whole 16-bit register to 1’s. The process begins by applying
successive 8-bitbytes of the message to the current contents of the register. Only the eight
bits of data ineach character are used for generating the CRC. Start and stop bits, and the
parity bit, donot apply to the CRC.
When generating the CRC, each 8-bit character is exclusive ORed with the register
117contents. The result is shifted towards the least signifcant bit (LSB), with a zero lled
64
Page 73
intothe most signifcant bit (MSB) position. The LSB is extracted and examined, if the LSB
equals to 1, the register is exclusive ORed with a preset, xed value; if the LSB equals to
0, noaction will be taken. This process is repeated until eight shifts have been performed.
Afterthe last (eighth) shift, the next 8-bit byte is exclusive ORed with the register’s current
value, and the process repeats for eight more shifts as described above. The nal contents
of the register, after all the bytes of the message have been applied, is the CRC value.
Whenthe CRC is appended to the message, the low-order byte is appended rst, followed
by the high-order byte.

Table 5-4 depicts reading 3 meters’ received basic data, total active energy, total active
energy tari1,total active energy tari2 from 17th slave device. The data type of energy is
dward. Each parameter takes 2 bits, and each bit takes 2 bytes. AcuRev 1300 series meters’
total active energy address are 900H, 901H. Total Active Energy tariff 1 address is 902H,
903H. Total Active Energy tari 2 address is 904H, 905H.
The slave device anwsers the master device's query. The response frame contains
slavedevice address, function code, data quantity and CRC check.
Table 5-5 is an example response of reading Total Active Energy (1.27kwh), Total Active
Energy tari 2 (1.00kwh), Total Active Energy tari 2 (0.27kwh). (when the energy data is
transmitting, real value= communication value/100).

2. The relationship between communication value and real value
The meter's communication value does not always equal the real value. There is a
conversion relationship between them. It is very important to be aware of the
parameterrelationship when users design a communication software, otherwise the result
may beincorrect.
