You will need to set the Voltage and current wiring mode, PT ratio and CT ratio. If no PTs were used, leave this setting as default. Information on the set up can be found in the ‘system parameter setting’ section of the user manual.

Also if communication is needed:

If Serial communication is to be used, you need to set the parity, baud rate and device address of the meter.

NOTE: The default parity, baud rate and device address can also be used.

If Ethernet communication is to be used, you need to set the network settings and the device address on the meter; also make sure the baud rate 2 is set as “38400” and parity 2 as “none 1”.

The wiring mode is based on your wiring configuration. You can find this in the “Wiring” section of the user manual.

When the system you are monitoring is using a three phase delta (3LL wiring mode) only the three phase total will be displayed on the meter. There are no phase readings because the system does not include a neutral, making all phase readings irrelevant in a 3 phase-no neutral delta system.

The meter displays accumulated energy reading. In order to know what the monthly consumption is, you can either take the readings from the previous month and subtract it from the current month OR reset the energy reading every month after noting down the energy consumption.

Please check if the CT ratio is setup correctly on the meter. CT1 stands for the primary side of the CT ratio and CT2 is for the secondary side. For example, if the CT has a ratio of 400:5, you should enter 400 for CT1 and 5 for CT2.

NOTE: The CT1 screen on the Acuvim L series has two rows, and CT2 screen can be seen on the screen after CT1

Negative power means your system is generating (delivering/exporting) energy. If your meter is monitoring a generator system, you should see negative power and this is correct. However, if your meter is monitoring a load that consumes energy, negative power (with high PF) usually results from 3 possibly reasons: the voltage and current are not aligned, the CTs are mounted in the reverse direction or the CT leads are wired to the meter in the opposite direction. Confirm that the voltage and current are aligned, for example, make sure phase ‘A’ correspond to voltage V1 and current I11 and I12 connections etc. Also make sure the P1/S1/H side of the CT faces the utility/source and that the black and white leads of the CTs are connected in the way specified by the CT manufacturer.

The Accuenergy 5A CTs requires the black go in first, that is, I11, I21, I31 should be black and I12, I22, I32 should be white, while the opposite colour code is used for Accuenergy 333mV CTs.

If Acuvim II series is used, you can reverse the CT current direction for each line from the system parameters setting mode instead of physically reversing the CT (this can be done on the meter or through the software).

NOTE:This can only be done if the alignment is correct and the CT direction or lead order is the only things wrong.

Please check voltage and current connections and make sure that voltage phase and current phase are aligned (i.e. phase A should correspond to voltage V1 and current I11 and I12 connections etc)

The meter supports single phase application (either single phase 2 wire or single phase 3 wire).

Old Platform: The wiring configuration should be set to 3LN and 3CT for both 2 wire and 3 wire single phase systems.

New Platform: The wiring configuration should be set to 1LN, 1CT for single phase 2 wire, and 1LL, 2CT for single phase 3 wire system.

The meter requires auxiliary power for its power supply. There are two power supply options available, the standard power supply option 100-415Vac or 100-300Vdc (100-240Vac or 100-300Vdc for AcuDC 240 series and EV300 series) and the low voltage power supply option (20-60Vdc). You can connect the power supply to a 120/240Vac outlet or connect it together with the voltage port (as long as the input voltage range is between 100 – 415 VacL-L) for the standard power supply option.

Yes you can use a jumper to power the meter as long as the voltage input is within the meters control power limit of 100-415Vac for P1 meters, and 20-60Vdc for P2 meters. V1 on the voltage input can be jumped to ‘L’ on the meters power supply terminal, and V2 of the voltage input can be jumped to ‘N’.

NOTE: If there is a neutral in the system you can jump the neutral from the voltage input to the ‘N’ terminal of the meters power supply, and use one of the voltage inputs to connect to ‘L’.

Battery systems are designed to provide back-up supplies during power outages. Since a discharge test is nothing other than a simulated power outage, there is no risk of battery damage. Batteries can normally be deep discharged (that is, discharged to the manufacturer’s end-of-discharge voltage) between 100 and 1,000 times, depending on the type of battery. Using a few of these discharge cycles for capacity testing has a negligible effect on overall battery life. Nevertheless, there is no reason to carry out discharge testing more frequently than recommended by the relevant standards.

A 24V DC power supply is required to generate the pulse output.

In order to wire the pulse output correctly the following connections are to be made:

• A 24V DC supply is required to attain the pulse. The positive 24V must be connected to the Digital Output Common (DOC). A 1 kΩ resistor is required in series to limit the current from the 24V DC supply
• The Digital Output 1(DO1) is connected to the positive terminal of the pulse counter
• The negative of the pulse counter is connected to the negative terminal of the 24V supply

NOTE: If you have the Acuvim II, L, DC the terminals used on the I/O modules are DO1 and DOC. If using the AcuRev 1310 Series the terminals used on the meter are P2 and P1. If using the AcuRev 2000 series the terminals used are E and C.

II: 256 samples per cycle (old platform); 512 samples per cycle (new platform)

IIR/IIE/IIW: 512 samples per cycle (old and new platform)

L: 128 samples per cycle (old platform); 512 samples per cycle (new platform)

AcuRev 2000: 64 samples per cycle

Acuvim series meter has a life expectancy (MTBF) of 17.5 years and does not require recalibration. In general, digital power meters do not require recalibration, only analog meters require that.

NOTE: if you require re-calibration, you can send the meter back to us for NIST-traceable calibration service; certificate will be provided.

The AcuRev 1310 and Acuvim II series support SunSpec.

The SunSpec registers can be found in the download section of our website, as well as the user manual for the meter also found in the downloads section.

Yes, our meters are bi-directional; they support bi-directional current measurement and can measure both consumed and generated energy.

Acuvim series meter cannot be used to monitor the load side of an AC drive. It can be used to monitor the source side of the AC motor drive system. This will give an accurate consumption.

Acuvim II, L and EV300 series meters are designed for single circuit applications; therefore, only one type of CT (with same CT ratio) can be used.

AcuRev 2000 series meter is designed for multi-circuit applications and different types of CTs with different CT ratios can be used.

Acuvim II, L and AcuRev 2000 series meter supports frequency from 45Hz to 65Hz.

The Acuvim II series meter supports 400Hz, if needed.

New platform meters have auto-frequency adaptation: This means the meter can automatically detects the frequency of the electrical system.

The default password of the meter is 0000.

The meter supports 2-wire RS485 serial bus. The meter does not support RS422 and RS232.

NOTE: We have Pre-configured USB-RS485 converter in stock. Some generic RS485-USB converters are not guaranteed to work.

The full Modbus map is included in the user’s manual of the meter, as well as the downloads section of the website.

NOTE: A copy of the Modbus address can be sent to you whenever needed.

Try polling the addresses in the 400000 range. The address to poll would then be the decimal equivalent plus 400000. You can also try using the offset of 1 making the address to poll be 400001 plus the decimal equivalent.

Some parameters will require calculations after reading the values from the modbus register while others will not. It is stated in the user manual what parameters require calculations and the ones that don’t.

You can get in contact with us if you require assistance.

Acuvim-CL and KL supports Modbus-RTU, while Acuvim-DL and EL supports Modbus-RTU and PROFIBUS-DP/V0. Acuvim II series supports Modbus-RTU, DNP3.0-RTU, DNP3.0-TCP, BACnet-MSTP, BACnet IP; Modbus-TCP, HTTPS webpage, email SMTP, SNMP, SNTP, HTTP/FTP Post, Mesh, WiFi, and DNP3.0-IP; PROFIBUS-DP/V0 (Profibus option). AcuDC240 series supports Modbus RTU. AcuRev 2000 series supports Infrared, Modbus-RTU, Modbus-TCP, HTTPS, SMTP, SNMP, SNTP, HTTP/FTP Post, and BACnet IP.

The meter supports 2-wire RS485 serial bus. The meter does not support RS422 and RS232.

NOTE: We have Pre-configured USB-RS485 converter in stock. Some generic RS485-USB converters are not guaranteed to work.

According to the RS485 specification, up to 32 meters can be connected to a single RS485 bus without repeaters. If you want to connect more meters on a RS485 bus, you can add RS485 repeaters to your RS485 network. A maximum of 247 slave nodes can be added to one RS485 line with repeaters. The overall length of the RS485 cable connecting all devices should not exceed 1200m (4000ft).

A USB-RS485 converter or RS232-RS485 converter can be used if your computer is equipped with a USB port or RS232 port.

NOTE: We have Pre-configured USB-RS485 converter in stock. Some generic RS485-USB converters are not guaranteed to work.

Also, if you have an Ethernet module, a CAT5 cable can be used to connect with the computer directly.

The communication icon blinks when the meter is communicating to the computer.

The RS485 terminal of the meter has 3 pins (14, 15, 16) or (1,2,3 on AcuRev). Pin 14 (A) is for differential + signal; pin 15 (B) is for differential – signal; pin 16 (S) is for shielding. Please make sure positive signals (+) are connected together and negative signals (-) are connected together.

NOTE: A pin-out diagram from our converter can be sent if needed.

When multiple meters are connected to the same RS485 line, make sure all meters have the same baud rate and parity with different device communication addresses. By default, the meter’s baud rate is 19200, parity is none 1 and the device communication address is 1.

32 repeaters.

When the module is connected to the meter correctly, you should be able to see the communication iconGet information, learning materials and videos from Accuenergy U(blink) and the Ethernet module iconGet information, learning materials and videos from Accuenergy U(solid) showing at the bottom of the meter’s front LCD screen. Please make sure that the Ethernet module is installed on the back of the meter FIRST before other modules are attached.

After making or modifying any network or communication settings a net reset of the communications module is required to ensure the settings are saved to the meter.

To reset from the meters display:

• Press ‘H’ and ‘V/A’ at the same time for a second and release. You will see meter flashing
• Press ‘P’ or ‘E’ to move the cursor to ‘Setting’. Press ‘V/A’ to enter the settings
• You will be prompted by a password screen. Enter the password if one is configured, otherwise leave the password as its default of ‘0000’ and press ‘V/A’ to continue
• With the cursor on ‘SYS’ press either ‘P’ or ‘E’ to move the cursor to ‘NET’ and press ‘V/A’
• Press either ‘P’ or ‘E’ to go to ‘N09 NET REST’. This is the net reset page of the meter
• Press ‘V/A’ to enter the edit mode, and press either ‘P’ or ‘E’ to change the setting to ‘RESET’
• Press ‘V/A’ to confirm the setting
• Now you can go back to the main metering screen by pressing ‘H’ and ‘V/A’ at the same time for a second
• Then press ‘P’ or ‘E’ to go to ‘Meter’ and press ‘V/A’ to enter the metering mode

The default password for the AXM-NET is ‘12345678’

The default password for the ‘Admin’ Access Level for the AXM-WEB-PUSH and AXM-WIFI is ‘admin’

The default password for the ‘User’ Access Level for the AXM-WEB-PUSH and AXM-WIFI is ‘view’

Firstly, make sure you ‘RESET’ the module on the NET RESET screen after you have changed the network settings on the meter; this will update the settings in the Ethernet module. Also make sure that the Baud rate 2 and Parity 2 in the system parameter settings of the meter are set to “38400” and “none1” respectively.

Secondly, make sure you have the right settings on the software before connecting; settings such as:

• IP address (default: 192.168.1.254)
• Modbus port (default: 502)
• Device type (e.g. Acuvim IIR)
• Device address (default: 1)

To connect your meter directly to a computer using a CAT5 Ethernet cable, you need to set the computer’s IP address within the same IP range as that of the meter, and also have the same subnet mask and default gateway as the meter; that is, you need to manually set the IP settings on the computer. This can be done through the LAN (Local Area Network) properties.

The table below gives an example of what the computer setting could be, with the given meter setting.

To manually set the IP settings on your computer, follow these steps:

• Go to ‘Network Connections’ setting on the computer. Disable the Wireless Network Connection and enable ‘Local Area Connection’. Right click on ‘Local Area Connection’ and click on ‘Properties’
• In the ‘Local Area Connection Properties’, select ‘Internet Protocol Version 4 (TCP/IPv4)’, and then click ‘Properties’
• After the settings have been entered, Click ‘OK’, and then click ‘OK’ again
• After the computer has been set, you can connect your meter to the computer directly using a CAT5 Ethernet cable

Please check if you can communicate with your meter in LAN (Local Area Network) by connecting the meter directly to the computer using a CAT5 Ethernet cable. (Look at the previous question)

If you are able to communicate with the meter in LAN connection with the correct settings, you should also be able to communicate in the internet (external network) environment.

Please make sure port forwarding is setup correctly in your router. The default Modbus port is 502 and the default HTTP port is 80. When setting up the meter’s network parameters, use internal network settings (i.e. internal IP address, subnet mask and gateway) instead of external settings (i.e. router’s external network parameters).

When accessing multiple meters internally, within the network, the meters must have different IP addresses.

When accessing multiple meters externally, outside the network, the meters must have different Modbus port.

The side of the CT that says P1/S1/H/h2 should face the utility side.

NOTE:Some CTs like ours, have arrow pointing in the direction of current flow.

5A Accuenergy CTs: The CT black lead should go in first before the white lead, that is black should go in to I11 and white to I12, black to I21 and white to I22, and black to I31 and white to I32.

333mV Accuenergy CTs: This is opposite to the case of the 5A CTs, that is, the CT white lead should go in first before the black lead.

Rogowski Coil (RCT) Accuenergy CTs: The CT’s white lead should be connected to I11 and brown lead should be connected to I12, white to I21 and brown to I22 and so forth. The shield wire can be grounded or left unconnected.

For AcuRev 2000 series, which uses the 333mV CTs, white will go into 37 and black to 38, white to 39 and black to 40 etc.

If AcuRev 2000 series is used with Rogowski Coil CT’s, the white lead will go into 37 and brown to 38, and so forth.

NOTE:All CT manufacturers do not have the same standard; use the right wire connection standard for the particular CT.

A Hall Effect sensor requires a power supply (±15 Vdc) while a shunt does not. Also, a shunt requires you to break the circuit to install while a Hall Effect sensor does not.

For the Rogowski coil, 333mV, and mA current transformer you should never ground the negative lead. The leads from these CTs can be connected directly into the terminal of the meter. Example:

Shorting blocks are only needed if the CT output is 5A/1A.There is no need to use shorting blocks for the Rogowski Coil, 333mV, and mA current transformers.

The password for User access level is ‘view’.

The password for Admin access level is ‘admin’.

The data logs can be retrieved and saved as a .CSV file by using an FTP client. The data log can be enabled in the Communication settings in the meters web interface.

The AXM-WEB-PUSH, AXM-WIFI and AcuRev 2000 with web option supports logging data onto its memory. Once this feature is enabled, the module can log up to 3000 days or 3000 months of data depending on the backup file length.

Typically, a transmitter, receiver and repeater are separate units in a wireless system. Unlike other wireless solutions, AcuMesh wireless transceiver has these three functions built into one model, so it works as transmitter, receiver and repeater from every single unit. The transceiver will automatically switch roles in the system. Each unit is able to connect to either master or slave RS485 devices to send and receive data/commands, and broadcast or repeat the command until every transceiver in the field is connected.

Yes, just like physical wire where you directly connect a daisy chain of RS485 devices to another unit or master device. One AcuMesh transceiver is connected at the end of one chain of RS485 devices, and another transceiver connect to another group of device or master device.

AcuMesh transceiver uses transparent communication, so any RS485 protocol can run over the wireless communication. Any protocol that can be transmitted on a traditional wired RS485 device will be able to run on AcuMesh wireless RS485 transceivers. A few popular example are Modbus-RTU and DNP 3.0 over RS485 port.

Yes, the AcuMesh transceiver will act as a repeater automatically when it is powered up to broadcast data across the private wireless network.

Yes. The AcuMesh transceiver uses default channel out-of-box, you won’t need to do any additional configuration to connect all devices within a single network. If you need multiple networks that are separate from each other, simply configure a different channel name for the transceivers in the other network group. AcuMesh transceivers will only identify other devices with the same channel name. Additionally, each channel allows for a separate password for better security and management.

Every AcuMesh transceiver has RS485 port and USB port built in. So you can either connect RS485 port to any RS485 devices, or connect USB to computer. When you connect via USB, the unit is capable of being powered by USB, so no power supply would be needed.

As AcuMesh works via transparent communication it does not add or modify any existing communication protocol. Consider it as an invisible wire device where no configuration is needed, no configuration is needed with AcuMesh transceivers as well. The exact same master device, whether it is a data acquisition server, computer running master software, or a PLC will remain the same. RS485 slave devices or sensors maintain the same configuration, such as device ID.

There is no limit in number of AcuMesh transceivers in the network, you can potentially add unlimited number of AcuMesh transceivers in the wireless mesh network. The limit is typically based on the protocol the system is using. For example, a daisy chain setup for RS485 devices with Modbus-RTU protocol has a limit of 32 devices without repeater.

• A maximum of 3 modules may be attached to the meter
• If a communication module is used (e.g. AXM-WEB-PUSH), it must be installed on the back of the meter FIRST before other modules are attached
• There can only be one communication module connected to the meter
• No more than 2 of the same I/O modules may be attached to the meter. The same two IO modules must have different component number, for example, 2 AXM-IO2 will be AXM-IO2-1 and AXM-IO2-2 (please see ordering information in the brochure for more details)

Modules must be installed before powering on the meter.

The default password of the meter is 0000.

• Click on the connect button located at the top left corner of the screen. NOTE: This is the yellow light bulb icon

Please check the CT ratio and CT1 setting. The meter uses 4 digits on the top row and 1 digit in the middle for setting up parameters for CT1. When you have a CT ratio of 450:5, CT1 should read 0045 on the top line and 0 on the next line. CT2 is fixed at 5 (or 1 for the 1A option meter).

The Acuvim-L series meter utilizes all 3 rows of the digit display to show kWh/kvarh/kVA values. As the accumulated energy increases, the most significant digit (digit with the highest order) will move upwards. For example, for 98,765,432.1kWh, the meter will show 9 on the top line, 8765 in the middle and 432.1 at the bottom.

The energy consumption can be found on the ‘Ep imp’ screen. This can be found by pressing the ‘E’ key one or more times on the meter screen.

The meter’s real time clock can only be set via communication using the software, except on the AcuRev 2000 series meter in which it can both be set using the software and the meter.

Using the Software

After connecting the meter to the computer using the software, follow these steps to set the real time clock for the meter:

Acuvim L series (DL and EL only)

• Click on ‘System Status’ section under the ‘Readings’ tab
• Select the method to set the clock (by using PC time or entering a date and time)
• Click ‘Set Device Clock’

Make sure you have the ‘wiring of the Three-phase User’ set as 3LN and the user channel as a number between 19 and 24 on the meter or between 301/201 and 306/206 on the software to represent the six three-phase channels the meter can measure.

To set this up on the meter:

• Press left or right on the main screen to have ‘SET’ highlighted. Press ‘OK’
• Enter the Password and Press ‘OK’ (if no password was created, press ‘OK’)

• When you have selected the appropriate user, change the user channel to a number between 19 and 24. Press ‘OK’ to confirm the setting

To set this up using the software:

• Go to the ‘User and CT Settings’ under the ‘Settings’ menu
• Select the ‘Wiring of Three-phase User’ as ‘3LN’
• Under ‘User and Channel Mapping’, choose the appropriate user and select the ‘Channel’ between “301/201 and 306/206”
• Click ‘Update Device’

The three phase wiring for the AcuRev 2000 series:

By default this value is configured to 220V and it affects any parameter that uses voltage in the alarm function. This configuration does not affect the meters ability to measure the voltage.

It is expressed by a percentage of the rated value for that parameter. For example the rated voltage is 220V and the set point is expressed as a percentage of that value.

The set point of the current is defined as a quarter of the full scale current. So if the current rating is 60A, a quarter of that is 15A. Therefore to set an alarm for when the current is greater than 15A the set point would be 100.

To view energy consumption on the AcuRev 2000 series, press the ‘left’ or ‘right’ key on the main screen until you select the ‘E’ option, after which you press ‘OK’.

The AcuRev 1310 has a sealing function, check to see if whether the meter has the seal installed.

Meter most likely has the seal installed on the meter if the hardware version is 2.03 or higher

For meters with hardware version 1.01, the sealed status will show if the terminal covers of the meter are installed.

The wiring detection can be found on the meter by pressing and holding the ‘SCROLL’ button. The voltage wiring is identified by a ‘U’, and the current wiring detection is identified by an ‘I’. The format of the wiring detection is:

U XXXXXX, where X is either ‘1’ or ‘0’.

• ‘0’ represents the connection is correct
• ‘1’ represents the connection is incorrect

If there are no errors the screen should read ‘U 000000’ for voltage and ‘I 000000” for current. On the meter display digits 1~3 (from left to right) would represent if a phase is not connected;Phase A Voltage missing, Phase B Voltage missing, Phase C Voltage missing. Digits 4~6 represent Phase A Voltage, Phase B Voltage, Phase C Voltage being connected incorrectly. For the Current detection, o the meter display digits 1~3 (from left to right) represent Phase A CT, Phase B CT, Phase C CT being in the reverse direction. Digits 4~6 represent Phase A CT, Phase B CT, Phase C CT being connected incorrectly.For example if the voltage wiring detection read ‘U 110000’, this would mean that the Phase A and Phase B voltage connection is missing.

By default the AcuRev 1310 series displays the total kWh reading. If you wish to see other parameters they can be added through the AcuRev 1310 Utility Software in the General Settings under the ‘Displayed Scan Parameters’ section.

Once the parameters are added, press ‘SCROLL’ on the meter to cycle through the selected parameters.

The input range for direct voltage measurement is 0-1000V and for current is 0-±10A.

Ensure the Hall Effect sensor has the required power supply (±15 Vdc). If the Hall Effect sensor has the required power supply then ensure the output of the sensor is wired correctly:

• Terminal 3 on the sensor is for output, ensure this is connected to ‘I+(5)’ on AcuDC 240 serie meter
• Terminal 4 on the sensor is the ground, ensure there are two wires from this terminal; one going to ‘I-(6)’ on the AcuDC 240 series meter and the other wire must be grounded in order to see an output

A Hall Effect sensor requires a power supply (±15 Vdc) while a shunt does not. Also, a shunt requires you to break the circuit to install while a Hall Effect sensor does not.

Make a comparison chart of both instruments.
