Chapter 2 Installation
Considerations When Installing Meters
• Installation of the meter must be performed by qualified personnel only, who
follow standard safety precautions through the installation procedures. Those personnel should have appropriate training and experience with high voltage devices. Appropriate safety gloves, safety glasses and protective clothing are recommended.
• During normal operation, dangerous voltage may flow through many parts of
the meter, including: terminals, any connected CTs (Current Transformers) and PTs (Potential Transformers), all I/O (Inputs and Outputs) modules and their circuits. All primary and secondary circuits can, at times, produce lethal voltages and currents. Avoid contact with any current-carrying surfaces.
• The meter and its I/O output channels are NOT designed as primary protection
devices and shall NOT be used for primary circuit protection or in an energy-limiting capacity. The meter and its I/O output channels can only be used as secondary protection. AVOID using the meter under situations where failure of the meter may cause injury or death. AVOID using the meter for any application where risk of fire may occur.
• All meter terminals should be inaccessible after installation.
• Do NOT perform Dielectric (HIPOT) test to any inputs, outputs or communication
terminals. High voltage testing may damage electronic components of the meter.
• Applying more than the maximum voltage the meter and/or its modules can
withstand will permanently damage the meter and/or its modules. Please refer to the specifications for all devices before applying voltages.
The installation method is introduced in the chapter. Please read this chapter carefully before beginning installation.

The circuit drawing of digital input is simplified as fig.2-28. When K is switched off, OUT is in high state. When K is switched on, OUT is in low state. The wire of digital input should be chosen between AWG22~16 or 0.5~1.3mm2.
2.3.8 Communication
Acuvim-L series meter uses RS485 serial communication and the ModbusRTU protocol. The terminals of communication are A, B, and S (14, 15 and 16). A is differential signal +, B is differential signal - and S is connected to the shield of twisted pair cable. Up to 32 devices can be connected on a RS485 bus. Use good quality shielded twisted pair cable, AWG22 (0.5mm2) or larger. The overall length of the RS485 cable connecting all devices can not exceed 1200m (4000ft). Acuvim-L series meter can be used as a slave device of a master device such as PC, PLC, Data Collector and RTU.

If the master does not have RS485 communication port, a converter (such as a RS232/RS485 or a USB/RS485 converter) will be required. Typical RS485 network topologies include line, circle and star (wye).
Data transfer format is start bit + 8 data bits + parity + stop bit. NON1, NON2, odd and EVEN could be selected in the mode of parity. NON1 represents non-parity, single stop bit; NON2 represents non-parity, double stop bit; odd represents odd parity, single stop bit; EVEN represents EVEN-parity, single stop bit.
All meter has been standardized. In order to improve the quality of communications, now offers the following Suggestions:
The shield of the RS485 cable must be connected to the ground at one end only. Every A(+) should be connected to A(+), B(-) to B(-), or it will influence the network, even damage the communication interface.
“T” type connection topology should be avoided. This means no new branches except from the starting point.
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, an anti signal reflecting resistor (typical value 120Ω- 300Ω/ 0.25W) is often used at the end of the circuit (the last meter of the chain) if the communication quality is distorted.
Use RS232/RS485 or USB/RS485 converter with optical isolated output and surge protection.

Page 77
Acuvim-L Series Power Meter
Chapter 3: Meter Display and Parameter Settings
77
2. Nonsinusoidal reactive power. The formula is as follows:
Where QD: Budeanu’s distortion power.
Q: Budeanu’s reactive power.
Apparent power (S): Three phase apparent power and total system apparent power are measured and displayed in the Acuvim-L series meter.
Power factor (PF): Three phase power factor and total system power factor are measured and displayed in the Acuvim-L series meter.
Frequency (F): The frequency of phase voltage input is measured as system frequency.
Energy (kWh): Energy is time integral of power. The unit is kWh. Since power is measured in
bi-direction, positive means importing and negative means exporting, energy is also expressed according to the power direction.
Import energy (Ep_imp): Energy imports from a source.
Export energy (Ep_exp): Energy exports to a source.
Reactive energy (kvarh): reactive energy is time integral of reactive power. The unit is kvarh.
Since reactive power is measured in bi-direction, positive means inductive and negative means capacitive, reactive energy is also expressed according to the load nature.
Import reactive energy (Eq_imp): inductive energy
Export reactive energy (Eq_exp): capacitive energy.
Apparent energy: apparent energy is time integral of apparent power. The unit is kVAh.
Harmonic parameter (not available for Acuvim-EL):

Total harmonic distortion: this factor is often used to express the power quality of the power system. The formula is as follows:
In the formula, U1 is Rms value of the voltage fundamental and Uh is Rms value of the voltage harmonic with order n.
Each harmonic rate: the percentage of each harmonic is divided by the fundamental.
Demand: real power demand, reactive power demand, total system power demand, and three phase current demand can be measured with the Acuvim-L series meter. The meter uses sliding window method for demand calculation. Demand interval can be selected from 1 to 30 minutes. Demand window slides one minute each time. For example, the demand interval is set as 3 minutes. If the total power of the 1st minute is 12, the 2nd minute is 14 and the 3rd minute is 10, the total power demand of the 3 minutes is (12+14+10)/3=12. If another minute passed by (the 4th minute) and the total power for the minute is 9, the total power demand after 4 minutes, according to the 3-minute interval, should be (14+10+9)/3 =
11.
Max/Min: Acuvim-L series meter can measure the max value of real system power, reactive power and apparent power and the max/min of the three-phase voltage and current. The data is stored in non-volatile memory and can be accessed or cleared via meter front or communication.
Unbalance factor: Acuvim-L series meter can measure unbalance factor of three –phase voltage and current using sequence vector method. The formula of voltage and current unbalance factor as follows:
Voltage unbalance factor = (RMS value of V1 (V12) negative component of the fundamental wave / RMS value of V1 (V12) positive component of fundamental wave) x 100 %

Page 79
Acuvim-L Series Power Meter
Chapter 3: Meter Display and Parameter Settings
79
Current unbalance factor = (RMS value of I1 negative component of the fundamental wave / RMS value of I1 positive component of fundamental wave) x 100 %
Energy measurement: The energy measurement type includes real time energy measurement and time of use (Acuvim-EL only) energy measurement. The function is described as follows:
Real time energy: the accumulation of energy for the kWh, kvarh and kVAh since cleared last time. The real time energy includes each single-phase energy, which could be useful for observing the increment of single-phase energy.
Time of use (TOU): User can assign up to 4 different tariffs (sharp, peak, valley and normal) to different time period within a day according to the billing requirements. The meter will calculate and accumulate energy to different tariffs according to the meter’s internal clock timing and TOU settings.
TOU setting: User can set a maximum of 12 TOU seasons, each season can be assigned to a TOU schedule (a maximum of 14 TOU schedules are available). Each 73 Acuvim-L schedule can be divided up into 14 segments (in which each segment can have its own tariff).
User can customize the TOU calendar (including its tariffs, seasons, schedules and segments) according to different applications. To make sure that the TOU calendar is setup correctly, the meter will check the TOU settings according to the predefined rules (see below for “TOU setting format requirement” for details). TOU function will be disabled if the TOU calendar is set up incorrectly. If no errors are found in the calendar and the TOU function is enabled, TOU energy accumulation will begin.
TOU setting format requirement:
1) Season setting parameter: The calendar year will be divided up into different
seasons depending on the season setting parameter. The parameter can be selected from any integer between 1 to 12. User must enter the correct value for the season setting parameter in accordance to the TOU season table. If the season setting parameter is set as 2, the first 2 slots of the TOU season table must be set, otherwise it will be considered as an invalid input (TOU function will be disabled).

2) TOU season format: Enter the start date into the TOU season table slot following
this format “MM-DD ID” - MM stands for the month, DD stands for the day and ID stands for the TOU schedule ID (available from 01 to 14). The dates should be organized so that they are in sequence according to the calendar year (the earlier date comes first and the later date comes last). For example, if 3 seasons are selected, the date parameters are January 1, June 6 and September 7, and TOU schedule 02, 01, 03 will be used respectively, the first TOU season table slot shall enter 01-01 02, the second slot shall enter 06-06 01, and the third slot shall enter 09-07 03. Entering 01-01 02 for the first slot, 09-07 03 for the second slot and 06­06 01 for the third slot is considered invalid.
3) Schedule setting parameter: The number of available TOU schedules depends on
the schedule setting parameter. The parameter can be selected from any integer between 1 to 14. This parameter determines the number of TOU schedules available for the TOU calendar setting. A maximum of 14 TOU schedules (from TOU Schedule #1 to TOU Schedule #14) can be used.
4) Segment setting parameter: Each TOU schedule consists of various timing
segments. The number of segments depends on the segment setting parameter setup. The parameter can be selected from any integer between 1 to 14 (inclusively). User must enter the correct value for the segment setting parameter in accordance to the TOU schedule table. If the segment setting parameter is set as 3, the first 3 slots of the TOU schedule table must be set, otherwise, it will be considered as an invalid input (TOU function will be disabled).
5) TOU schedule format: Each TOU schedule represents a 24-hour cycle. Similar to
TOU season format, enter the start time into the TOU schedule table slot following this format “HH:MM ID” - HH stands for hour (in 24 hr format), MM stands for minutes and ID stands for tariffs (available from 00 to 03). The time should be organized according to the hour sequence. For example, if 3 segments are selected, timing parameters are 01:00, 15:30, 22:45, the order of the 3 segments should be one of the following: 01:00, 15:30, 22:45 or 15:30, 22:45, 01:00 or 22:45, 01:00, 15:30 Entering time information in a wrong sequence (for example, entering 15:30, 01:00, 22:45) is considered as an invalid operation, TOU function will be disabled.

6) Tariff setting parameter: This parameter corresponds to the number of tariffs
available for the TOU calendar and can be selected from any integer from 0 to 3. The four tariffs: sharp, peak, valley and normal are represented by 4 integers: 0, 1, 2 and 3 respectively. If the tariff setting parameter is set to 3, all of the 4 tariffs will be available for the TOU calendar; if the parameter is set to 1, only the first 2 75 Acuvim-L tariffs (sharp and peak) will be available.
7) Holiday setting parameter: This parameter can be set from any integer between 1
and 30, meaning a maximum of 30 holidays can be programmed to the TOU calendar. If the holiday setting parameter is set as 3, the first 3 slots of the holiday schedule must be set, otherwise it will be considered as an invalid input (TOU function will be disabled).
Note: User can either customize the TOU calendar factory settings or use the default factory settings. User can reset the TOU calendar to its default value either via communication.
8) Holiday schedule: The holiday schedule uses the same format as the TOU seasons
“MM-DD ID”. User can select which TOU schedule to be used for the holiday. The dates of the holiday schedule do not need to be organized in a sequential order (i.e. the first slot can be January 1, the second slot can be December 26 and the third slot can be December 25).
9) Daylight saving time (DST): under the circumstance that DST is enabled, if you
choose the fixed date option, you set a fixed date for DST, the format is month / day / hour / minute / adjust the time (in minute). If you choose the non-fixed data option, you set a day in a week for DST, the format is month / which week/ day / hour /minute / adjust time (in minute). Once DST is enabled, DST will be automatically implemented by the chosen option.

For example, if a user wants to set Saturday and Sunday effective, he should put 65 (1000001) into the Weekend Setting field. When the meter clock is within the pre-set Weekend Schedule, the energy will accumulate under the tariff that corresponds to the Schedule.
Note: Holiday schedule has the highest priority among all the schedules followed by the Weekend Schedule. That is, when set appropriately, holiday and weekend schedules override normal (weekday) TOU settings. When a holiday falls in a weekend, the holiday schedule overrides the Weekend Schedule.
Record and Clear of Maximum Demand
Acuvim-EL could record the maximum power and current demand under different tariffs, when the TOU Function is enabled and the setting of time table is correct. It also can clear the value under different tariffs.
There are two ways of resetting Current Month TOU:
1. End of Month: This is the default method. All values from Current Month TOU will
be copied over to Prior Month TOU at the very beginning of each month (the first day of each month at time 00:00:00).
2. Assign: User can select when should the values from Current Month TOU be copied
over to Prior Month TOU. User can set the time in the following format “DD HH:MM:SS” - DD stands for day, HH stands for hour, MM stands for minute, SS stands for second. Similar to the previous method, once Current Month TOU is transferred to Prior Month TOU.

Digital output (DO)
As shown in Fig.3-95, the DO type includes alarm output and energy pulse output. DO type can be set via software as well.
Over/Under limit alarming:
Acuvim-BL, Acuvim-DL and Acuvim-EL has over/under limit alarming capability. When the monitored parameter goes beyond/below the preset limit and stays at the level over the preset amount of time delay, the over/under limit alarm will be triggered. The meter LCD screen backlight will flash and the corresponding digital output (DO) will be activated until the parameter condition returns to normal. Upon alarming, DO can be used to activate devices such as safety beacon light and buzzer. Each DO supports 1 alarming parameter. An over/under limit alarming example is shown below.
For example:
Alarming Condition: when Phase B current goes above 180A (CT ratio is set as 81 Acuvim-L 200:5) for over 15 seconds, over limit alarm will be triggered, alarm signal will be set out via DO1. Setting procedures should be as follows: Enter DO parameter setting mode by pressing “P” and “E” simutaneously under system parameter setting mode.
1) Set DO1 mode to 1 (alarm output)
2) Set delay time to 50 (the base unit of delay time is 300ms, the setting value should
be 15/0.3=50)
3) Set alarming parameter to 8 (tracking object for parameter 8 isPhase B current))
4) Set inequality sign to 1 (greater than)
5) Set alarm value to 4500 (according to Table 4-9. Conversion relationship of basic
measurements from Chapter 4.4 <>, the setting relationship is I=Rx*(CT1/CT2)/1000, Rx=4500) Press “V/A” to accept change then press “P” and “E” simutaneously to exit DO parameter setting mode.

Energy Pulse Output:
Acuvim-BL, Acuvim-DL and Acuvim-EL has Energy pulse output function. Each energy pulse output channel can be set to monitor one of the four energy parameters (Ep_imp, Ep_exp, Eq_imp or Eq_exp). Pulse constant and pulse with can also be set according to user’s requirement. Pulse constant stands for amount of energy (kWh or kvarh) per pulse; pulse width stands for the time duration for each pulse. DO will send out a pulse signal when the accumulated energy reaches the pulse constant value. Related parameters: pulse energy output ranges from 0 to 4 corresponding to none, Ep_imp, Ep_exp, Eq_imp, Eq_ exp. Pulse constant ranges from 800 to 60000; Pulse width ranges from 1 to 50 (word) with a unit of 20ms. The shortest interval between two pulses is 20ms. 82 Acuvim-L In practice the pulse width and the pulse ratio are selected according to system power. The relation of the two parameters should satisfied following expression: ((1000*3600s)/P*Pulse_Const)>pulse width. In the expression, the unit of the power or reactive power is w or var.

(1) DI function introduction:
The DI type can be set as shown in Fig.3-95 Extend IO parameter setting.
If SOE record function is selected, the DI will work as SOE state mode as shown Fig. 3-96 SOE record display; if the counter is selected, the DI will work as input pulse accumulation mode as shown in Fig.3-87 DI count and status display.
(2) SOE (Sequence of Event) function:
1) At present, the event allows the cycle of 20 SOE recording. When DI is in SOE state
mode, once the DI input level changes occur, an SOE event will be recorded. In this way, it will achieve 20 SOE event loop recording. The event format: Year, Month, Day, Minute, Seconds, Millisecond, DI status.
2) SOE function judges the single read event value. When a single event is read, if the
value is not the latest event in the log, it reads this single event and the record number will be increased. If a record is the latest event, the incident remains unchanged. The previous events can be read by the record numbers. If the value is not currently reading the latest value of the event log, it reads the current single event and the record number will be incremental, if current reading record number is the latest event record number, a single incident remains unchanged. by re-written a single event number, the user can implement the previous event re-read.
(3) Pulse Counter function: When the DI type is set to Pulse Counter, corresponding to the accumulated pulse constant value, it achieves the cumulative function of DI input pulses. If pulse constant is 1, DI input receives 1 input signal then cumulative pulse amount adds 1. If pulse constant is 10, DI input receives 10 pulses then cumulative pulse amount adds 1.

This chapter will mainly discuss how to operate the meter via communication port using software. To master this chapter, you should be familiar with Modbus and read other chapters of this manual to make sure that you have a good understanding of the functions and applications of this product.
This chapter includes: Modbus protocol, format of communication and data address table and Acuvim-L application details.
4.1 Modbus Protocol Introduction
ModbusTM RTU protocol is used for communication in Acuvim-L series meter. Data format and error check methods are defined in Modbus protocol. The half-duplex query and respond mode is adopted in Modbus protocol. There is only one master device in the communication net. The others are slave devices, waiting for the query of the master.
Transmission mode
The mode of transmission defines the data structure within a frame and the rules used to transmit data. The mode is defined in the following which is compatible with Modbus RTU Mode*.

Table 4-1 data frame format
Address field
The address field of a message frame contains eight bits. Valid slave device addresses are in the range of 0~247 decimal. A master addresses a slave by placing the slave address in the address field of the message. When the slave sends its response, it places its own address in this address field of the response to let the master know which slave is responding.
Function field
The function code field of a message frame contains eight bits. Valid codes are in the range of 1~255 decimal. When a message is sent from a master to a slave device the function code field tells the slave what kind of action to perform.
Table 4-2 Function code
Data field
The data field is constructed using sets of two hexadecimal digits, in the range of 00 to FF hexadecimal. The data field of messages sent from a master to slave devices contains additional information which the slave must use to take the action defined by the function

code. This can include items like discrete and register addresses, the quantity of items to be handled, and the count of actual data bytes in the field. For example, if the master requests a slave to read a group of holding registers (function code 03), the data field specifies the starting register and how many registers are to be read. If the master writes to a group of registers in the slave (function code 10 hexadecimal), the data field specifies the starting register, how many registers to write, the count of data bytes to follow in the data field, and the data to be written into the registers.
If no error occurs, the data field of a response from a slave to a master contains the data requested. If an error occurs, the field contains an exception code that the master application can use to determine the next action to be taken. The data field can be nonexistent (of zero length) in certain kinds of messages.
Error Check Field
Every message includes an error checking field which is based on the Cyclical Redundancy Check (CRC) method. The CRC field checks the contents of the entire message. It is applied regardless of any parity check method used for the individual characters of the message. The CRC field is two bytes long, containing a 16-bit binary value. The CRC value is 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 field. 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 89 Acuvim-L applying successive 8-bit bytes of the message to the current contents of the register. Only the eight bits of data in each character are used for generating the CRC. Start and stop bits, and the parity bit, do not apply to the CRC.
When generating the CRC, each 8-bit character is exclusive ORed with the register contents. The result is shifted towards the least significant bit (LSB), with a zero filled into the most significant bit (MSB) position. The LSB is extracted and examined, if the LSB equals to 1, the register is exclusive ORed with a preset, fixed value; if the LSB equals to 0, no action will be taken. This process is repeated until eight shifts have been performed. After the 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. After all the bytes of the message have been applied, the final contents of the register, which should exchange the high-byte and the low­byte, is the CRC value. When the CRC is appended to the message, the low-order byte is appended first, followed by the high-order byte.
