1. What do I need to do for the initial set up and programming of my meter?

   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”.

2. How do I know what wiring mode to select on the meter?

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

3. I’m not able to read any three phase data, only the total of the three phases are shown?

   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.

7. Why is the meter’s Current value (I) very small and Energy reading accumulating slowly?

   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

8. Power shown on meter is negative but power factor is high, why is this so?

   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.

9. Why is the Power Factor low?

   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).

10. Does the meter support single phase application?

    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.

11. Does the meter require external power supply?

    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.

12. Can I use the voltage input for the control power of meter?

    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’.

13. Is a power supply needed for Pulse Output?

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

14. How to connect Pulse Output to pulse input?

    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.

15. What is the refresh rate of the meter screen and meter register?

    (for 60Hz system)	Acuvim || Series	Acuvim L Series
    LCD Screen	1s	1s
    Modbus Data	100ms	1s

16. What is the sampling rate per cycle of the meter?

    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

17. What is the life expectancy of the meter and does it require recalibration?

    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.

18. Do your meters support SunSpec?

    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.

19. Are the meters bi-directional?

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

20. Can I use the meter to monitor the load side of a variable frequency drive (AC drives)?

    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.

21. Can I use more than one type of CT for one meter and does it support multiple circuits?

    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.

22. What is the frequency range of the meter?

    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.

   • 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.

3. What is the default password for the Ethernet module?

   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’

4. Why am I unable to connect to software even though I have all meter settings correctly set?

   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)

5. How do I connect my meter directly to my computer using a CAT5 Ethernet cable?

   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.

   	Meter Setting	Computer Setting
   IP Address	192.168.1.254	192.168.1.100
   Subnet Mask	255.255.255.0	255.255.255.0
   Gateway	192.168.1.1	192.168.1.1

   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.

6. What should I check if I am not able to view the meter via internet (external network)?

   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).

7. What needs to be different when accessing multiple meters?

   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.

1. What are the passwords for the AXM-WEB-PUSH access levels?

   The password for User access level is ‘view’.

   The password for Admin access level is ‘admin’.

     • Log Interval:Select how frequently the module will log the data to the file from the drop down list. The logging interval can be from 15 seconds to 1 month.
     • Backup File Length: Select the length of the log file as either 1 day or 1 month of data from the drop down list.
     • Backup File Prefix: Provide a name for the log file which will be appended to the beginning of the log file. By default ‘logger1’ will be appended to the beginning of the log file.
     • SFTP Enable: In order to download the data log from the module, select ‘Enable’. The log file will then be downloaded using an FTP client with the following credentials:
     • Host: sftp://IP addressof the meter
     • Username:sftp user
     • Password: accuenergy
     • Port: 22
     • By default the password for retrieving the backup log files is ‘accuenergy’. The user can configure any password or can reset to the default of accuenergy by clicking on the ‘Reset SFTP Password’.

     • Offline: An Offline alert is sent out when the meter is no longer online and no data is received by the server. With this alert type you can configure the time duration this lasts before an alert is sent out.
     • Parametric: A parametric alert is when you choose a specific parameter (i.e. Phase A voltage, total current, etc) and the selected parameter is over or under the threshold value an alert will be sent out. You can choose from energy, I/O, and real time metering parameters.
     • NOTE: When creating an alert for a Calculated Meter, the only type of alert that can be created is Parametric.
   • Enter in an email address so you can be notified when an alert has taken place.
   • Once all the alert settings are configured click ‘SUBMIT’.

The AcuMesh wireless RS485 transceiver works like an “invisible wire”. It is intended to replace a traditional, wired RS485 network in a building or facility, reducing a significant amount of installation time, cost, and difficulty.

1. Which model is a transmitter, receiver and repeater?

   Typically, a transmitter, receiver, and repeater are separate units in a wireless system. Unlike other wireless solutions, AcuMesh wireless transceiver has all three functions built in, so it works as transmitter, receiver and repeater from every single unit. The transceiver will automatically switch roles in the system. Each unit is capable of connecting 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.

2. Can I connect more than one units to one AcuMesh transceiver?

   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.

3. What protocol does it support?

   AcuMesh transceiver is compatible with Modbus-RTU over RS485.

4. If the two transceivers are not able to connect to each other due to distance, can I add another transceiver between, as a repeater, without connecting to an RS485 device?

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

5. Our application requires multiple groups of wireless networks, and they cannot interfere with each other or communicate with each other. Can the networks be configured this way?

   Yes. The AcuMesh transceiver uses a default channel out of the 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 second 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.

6. If the master device is a computer, do you offer a RS485 to USB converter?

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

7. Do you need to assign an address to each transceiver?

   Since AcuMesh works via transparent communication, it does not add or modify Modbus-RTU protocol. Think of it as operating the same as a wired Modbus-RTU connection. A master device, whether it is a data acquisition server, a computer running master software, or a PLC will remain the same without any separate configuration required for the wireless connection. RS485 slave devices or sensors maintain their settings as well, such as Device ID.

8. How many AcuMesh transceivers can I connect in one network?

   There is no limit to the number of AcuMesh transceivers that can be added to a single wireless mesh network. The limitation is imposed by the Modbus-RTU protocol. For example, Modbus-RTU daisy chain topology has a limit of 32 devices without a repeater.

9. How do I power up the AcuMesh transceiver?

   The AcuMesh transceiver can be powered up using a 24Vdc supply. If connecting the transceiver to a computer, the 24Vdc is not required and can be powered by the provided USB cable.

10. What is the difference between the AcuMesh-L and the AcuMesh-K?

    The only difference between the AcuMesh-L and AcuMesh-K transceivers is the form factor, the AcuMesh L is DIN rail mounted and the AcuMesh-K is surface mounted.

1. How many modules can be attached to the meter?

   • 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).

2. Do I need to power off the meter before installing the modules?

   Modules must be installed before powering on the meter.

3. Where can I find the user’s manual for the meter and modules?

   User’s manual for the meter and modules are available here.

4. What is the default password of the meter to enter the systems parameter settings page?

   The default password of the meter is 0000.

1. Why is the current 10 times bigger than what it should be after setting up the meter?

   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).

2. Energy readings are alright at first; however it seems to reset itself after a while. All the settings look correct and no resets have been performed. What can the problem be?

   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.

1. Why can’t I view all the three phases at once for a three phase user on the software?

   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’)
   • Press any of the arrow keys until you get to the wiring mode ‘P29’ screen. Change the wiring mode to ‘3LN’ by pressing ‘OK’ to enter editing more, any of the arrow keys to change the setting to ‘3LN’ and ‘OK’ to confirm the change.
   • Press any of the arrow keys until you get to the channel setting ‘P30’ screen. Press ‘OK’ to enter editing mode, left or right key to switch between ‘Name’ and ‘Channel’, up or down key to change the specific name or channel.
   • 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’.

2. How do the current input channels correspond to the voltage input?

   The three phase wiring for the AcuRev 2000 series:

   		Channel 1	Channel 2	Channel 3	Channel 4	Channel 5	Channel 6
   AcuRev 2020 Current Input Channels	Phase A	1	2	3	10	11	12
   	Phase B	4	5	6	13	14	15
   	Phase C	7	8	9	16	17	18

3. What is the rated voltage in the General Settings of the AcuRev Utility Software for?

   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.

4. Why is the alarm set point in terms of percentage?

   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.

1. Why can’t I change any settings on the meter?

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

2. Why does it show Seal Status as ‘Sealed’?

   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.

3. How to read incorrect wiring detection function?

   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.

4. Why do I only see kWh on the meter display?

   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.

1. What is the direct input voltage and current range?

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

2. Why does the DC meter show 0A when using a Hall Effect sensor?

   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.

3. What are the differences between Hall Effect sensor and a shunt?

   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.

   	Intrusive	Power Supply
   Hall Effect Sensor	Does not require breaking circuit to install	Requires ±15 Vdc power supply
   Shunt	Requires breaking circuit to install	Does not require power supply

1. What side of the CT should face the utility?

   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.

2. How should the CT wires be connected to the meter?

   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.

3. Do I need to ground the negative lead of my 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:

   

4. Do I need to use shorting blocks?

   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.

1. What are the different Panel boxes available and what are the differences?

   We have the NEMA4 and NEMA4X panel boxes. The NEMA4 box is made of steel while the NEMA4X box is made of plastic. NEMA4 Panel box is an indoor panel box while the NEMA4X panel box is waterproof. A comparison table is shown below.

   	AcuPanel 9104 (NEMA 4)	AcuPanel 9104X (NEMA 4X)
   Weight	18 lbs	7 lbs
   Water-Proof	No	Yes
   Anti-Corrosive	No	Yes
   Outdoor Installation	No	Yes
   Material	Steel	Polycarbonate
   Dust-Proof	Yes	Yes
