1 APPLICATION

The ND30 meter is a programmable digital instrument designed for the measurement of 1-phase 2­wire and 3-phase 3 and 4-wire power network parameters in balanced or unbalanced systems. The
measured values are displayed on a 3,5’’ TFT full-color screen, resolution: 320 x 240 pixel. The meter
enables control and optimization of the power electronic devices, systems and industrial installations.
The meter provides measurement of: RMS of voltage and current, active, reactive and apparent power,
active, reactive and apparent energy, power factors, frequency, the harmonics of current and voltage /up to
51st/, THD of voltage and current, averaged active and apparent power P Demand, S Demand, averaged
current I Demand /15, 30 or 60 minutes/. Voltages and currents are multiplied by given voltage and current
ratios of the measuring transformers. Power and energy indications take into account all programmed ratio
values. The value of each measured value can be transmitted to the master system via the RS-485 or
Ethernet interface. Three relay outputs signal the overflow of the chosen value and the programmable
analog output maps the assigned parameter. The temperature inputs can be used to control the
temperature of the transformers windings, motors.

There is a galvanic separation between following units of the meter:

- supply

- voltage inputs

- current inputs

- RS485 interface

- Ethernet interface

- alarm outputs

- analog output

- temperature input Pt100

8.1 INTERNAL MEMORY

The ND30 meters are equipped with 4MB of internal memory and 8GB memory for storing the
recorded data. 4MB internal memory allows to register 40,960 records. The memory is a ring
buffer type one.

8.2 COPYING ARCHIVE

If the 4MB internal memory is full at 70% or forced at any time: in Arc
"Copy the archive to a CSV file" parameter to "Yes". The recorded data will be copied to the files archive.
To start the procedure of copying archive can also be done via the RS485 interface (register 4125) or by

Example: files archive with archiving period of 5 seconds allows you to register data for 2 years. If the files
archive is full at 70% - archive used in % will become orange (see: Status 3 Register – address 7561).

When the files archive is full (less then 14 days at 1 sec. interval to completely use a the files archive
space) the color will change to flashing red.

The ND30 meter creates the directories and the files the files archive while the internal memory is being
copied. An example of the directory structure is shown in Figure 26.

Fig.26. Directory structure in the files archive

a in the files archive is stored in the files in the directories (year, month archive copy) - see Fig.

Dat

26. The file names are marked by day and time of the first record and have the ddhhmmss.csv
format, where: dd-day, hh-hour, mm-minute, ss-second.

8.3 ARCHIVE FILES STRUCTURE

The archived data files are in the form of the columns, where each column of data is separated by

mma. A column description is in the first line of the file. Data records are sequentially

a co
arranged in the rows. An example of the file is shown in Figure 27.

Fig.27. An example of the archive data file

The fields in the line describing the record have the following meanings:

 date – date of data recording, date separator is the character "-"
 time – hour, minute, second of recorded data, a time separator is the character ":"
 record index – unique index record. Each record has a unique number. This number increases

9.3 Ethernet interface 10/100-BASE-T

The ND30 meters version ND30-XX2XXXX are equipped with an Ethernet interface for connecting
the meter (using the RJ45 socket) to the local or global network (LAN or WAN). The Ethernet interface
allows to use the web services implemented in the meter: web server, FTP server, Modbus TCP/IP.
Configure Ethernet group parameters to use the meter's network services. The standard Ethernet
parameters of the meter are shown in Table 9. The main parameter is the IP address of the meter, e.g.

.0.1.161, which must be unique in a network the device will be connected to. The IP address can be

10
assigned to the meter automatically by the DHCP server present in the network if the meter has an option
to obtain an address from DHCP server enabled: Ethernet Addresses DHCP On If the DHCP
service is disabled then the meter will work with the default IP address allowing the user to change the IP
address, e.g. from the menu of the meter. Change of the Ethernet parameters can also be done via the
RS485 interface. So it is required to confirm the changes by writing the value "1" to the register 4149. The
Ethernet interface is rebooted in accordance with the new parameters after applying changes - all services
of the Ethernet interface are restarted.

9.3.1 Connecting 10/100-BASE-T interface

Connect the device to a TCP/IP network using the RJ45 socke
of the meter to get access to the Ethernet services.

The meter's RJ45 socket LEDs description:

• yellow LED

- illuminates when the meter is properly connected to the Ethernet 100 Base-T, does not

t located at the back / terminal side /

36 User's manual

illuminate when the meter is not connected to a network or is connected to a 10-Base-T.

• green LED - Tx/Rx, illuminates (irregularly illuminates) when the meter sends and receives data,
illuminates continuously when no data is transmitted

It is recommended to use a twisted pair cable to connect the meter to the network:

• U/FTP – twisted pair cable with a separate foil for every pair

• F/FTP – twisted pair cable with separate foil for every pair and additional foil shielding for the cable

• S/FTP (former SFTP) – twisted pair cable with separate foil for every pair and additional mesh cable

shielding

• SF/FTP (former S-STP) – twisted pair cable with separate foil for every pair and additional mesh
and foil cable shielding

The twisted pair cable categories according to the European standard EN 50173 are minimum:

Class D (category 5) - for high-speed local area networks, includes the applications using the frequency
band up to 100 MHz. For Ethernet connection use the category 5 STP type twisted-pair cable (shielded)
with RJ-45 connector, wiring colors (according to Table 11), compliant to the following standards:

• EIA/TIA 568A for both connectors in strike-through connection (i.e. between ND30 and hub or
switch)

• EIA/TIA 568A for the first connector and EIA/TIA 568B for the second one in the cross-over
connection (i.e. when connecting the ND30 meter to the computer).

• Table 13

9.3.2 Web Server

ND30 meter provides its own web server which enables remote monitoring of the measuring

The

values and reading a status of the meter. A web page allows in particular to:

• obtain information about the device (serial number, code execution, software version, bootloader
version, version (standard or special),

• preview current measuring values, read a device status,

• select the web page language

37 User's manual

Access to the server can be achieved by entering the IP address of the meter in the web browser,
for example: http://192.168.1.030 (where 192.168.1.030 is set address of the meter). The default web
server port is the port "80". The server port can be changed by the user.

Note: A browser with JavaScript enabled and compatible with XHTML 1.0 is required for correct
operation of the website (all popular browsers, Internet Explorer version 8 minimum).

9.3.2.1 General view

Fig. 29. View of the meter website

9.3.2.2 Web user selection

The meter has two user accounts for the web server protected by the individual passwords:

• user:

• user: "user”, password: "pass” - access only to the preview of the parameters.

Calling the IP address of the meeter in a browser, e.g. http://192.168.1.30 will display a start website to
enter a user name and a password.

"admin”, password: "admin” - access to the configuration and preview of the parameters

38 User's manual

Fig. 30. View of the meter's web server login window

server user name can not be changed. You can change the password for each user - for safety

Web
reasons it is recommended to change the passwords. Changing the password is possible only through a
web page in the "Ethernet" parameter group. The passwords can be up to 8 characters. If the password is
lost (what disables using the web server), restore the default settings of the Ethernet interface e.g. from the
menu: Settings  Default settings Yes or entering the value "1" to the register 4152. All standard meter
parameters and Ethernet interface parameters (see Table 9) and the passwords of the web server users
will be restored:

user "admin” password: "admin”;
user "user” password "pass”.

9.3.3 FTP Server

FTP file sharing protocol has been implemented in the ND30 meters. The meter acts as a

The
server, allowing the users to access the internal memory of its file system. Access to the files is possible
using a computer, a tablet with installed FTP client or other device acting as a FTP client. The standard
FTP ports are used for transferring files, "1025" - data port and "21" -- commands port. A user can change
the port used by the FTP protocol if necessary. Please note, that the port configuration of the FTP server
and the client must be the same.

The FTP client program can work in a passive mode. The connection is fully made by the FTP client in the
passive mode (a client chooses the data port). It is possible to use up to one connection at the same time

for the file transfer with the meter, so you should limit the maximum number of a FTP client connections to 1.

39 User's manual

9.3.3.1 FTP user selection

The meter has two user accounts for the FTP server protected by the individual passwords:

• user: "admin”, password: "admin” - access to read and write the files

• user: "user”, password: "passftp” - access to read only the archive files.

The FTP user names can not be changed but you can change the password for each user - for
safety reasons it is recommended to change the passwords. Changing the password is possible only
through a web page in the "Ethernet" parameter group. The passwords can be up to 8 characters. If the
password is lost (what disables using the FTP server), restore the default settings of the Ethernet interface
e.g. from the menu: Settings

Default settings Yes or entering the value "1" to the register 4152. All



standard meter parameters and Ethernet interface parameters (see Table 9) and the passwords of the FTP
server users will be restored:

user "admin” password: "admin”;
user "user” password "passftp”.

The program FileZilla could be an example of the FTP client. You can view and download the
archive files by entering the IP address of the meter in the address field.

9.3.4 Modbus TCP/IP

The ND30 meter allows access to the internal registers via the Ethernet interface and Modbus
TCP/IP protocol. It is necessary to set the unique IP address of the meter and set the connection
parameters listed in Table 14 to set up a connection.

Table 14

The device address is the address of the device for Modbus TCP/IP protocol and is not a value
equal to a address value for Modbus RS485 protocol (Modbus network address register 4100). Setting the
parameter "Device address for Modbus TCP/IP protocol" of the meter to the value "255", the meter will skip
the address analysis in the frame of Modbus protocol (broadcast mode).

Energy is made available in hundreds of watt-hours (var-hours) in double 16-bit register, and for this
reason, you should divide them by 100 when calculating values of particular energy from registers, e.g.:

Active import energy = (reg. value 4426 x 65536 + reg. value 4427) / 100 [kWh]
Active export energy = (reg. value 4428 x 65536 + reg. value 4429) / 100 [kWh]
Reactive inductive energy = (reg. value 4430 x 65536 + reg. value 4431) / 100 [kVarh]
Reactive capacity energy = (reg. value 4432 x 65536 + reg. value 4433) / 100 [kVarh]
Apparent energy = (reg. value 4434 x 65536 + reg. value 4435) / 100 [kVAh]

11 SOFTWARE UPGRADE

11.1 Upgrade of the meter website

Upgrade can be done via FTP server.
You can upgrade the website in the tab Website upgrade. Copy the file ND30_upd.tar to the main folder of
the meter. Then turn off and turn on the meter, i.e. reset the meter. The file ND30 upd.tar will be extracted

to the appropriate folders. It can take approx. 1 minute. The messages informing about the progress of
extracting will be displayed on the meter screen.

11.2 Firmware update - main program of the meter

A feature implemented in the ND30 meters enables to upgrade firmware using a PC with eCon
software installed. Free eCon software and the update files are available by request from PCE
Instruments. Upgrade of meter software (firmware) can be done via RS-485 interface. Go to UPDATER
tab to upgrade.

Fig. 33. Program window view: a) eCon, b) software upgrade

Note: Software update automatically resets meter settings to default settings, so it is recommended to

save meter settings using eCon software before upgrading. After launching eCon software, set in the
settings required serial port, baud rate, mode and address of the meter. Next, select the ND30 meter and
click Config. Click the down arrow icon to read all of the settings then the disk icon to save the settings
to a file (required to restore the settings later). After selecting the option Update firmware (in the upper
right corner of the screen) the window Updater will be opened – Fig. 33b. Click Connect.

The Messages information window displays information concerning upgrade
process. If the port is opened correctly, a Port opened message appears. Upgrade mode is enabled
using either of the two methods: remotely via the Updater (using LPCon settings: address, mode, baud
rate, COM port) and by turning a meter on while pressing the button (while entering bootloader
mode the button is used to set communication settings: baud rate 9600, RTU8N2, address 1). The
display will show the bootloader version, while the Updater program displays the message Device found
and the name and version of the connected device. Click the "...” button and browse to the meter upgrade
file. If the file is opened correctly, File opened message is displayed. Press the Send button. When
upgrade is successfully completed, the meter begins normal work while the information window
displays Done message and upgrade elapsed time. After the Updater window is closed, go to
parameter group Service parameters, select the option Set default settings of a meter and press a button
Restore. Then press the folder icon to open a previously saved settings file and press the up arrow
icon to save the settings in the meter. Current software version can be checked by reading the
welcome message when switching the meter on.

Note: Turning meter supply off during upgrade may result in permanent damage!

12 ERROR CODES

During the meter operation the error messages may be displayed. Following list shows reasons
of errors.

- Err bat – displayed when the battery of the internal RTC clock is used up. Measurement is

carried out after switching the supply on and every day at midnight. The message can be turned off by
pressing the button . The disabled message remains inactive till the renewed switching of the

meter on.

- Err CAL, Err EE – meter memory is damaged. In such case a meter should be sent back to the
manufacturer.

- Err PAr – incorrect operational parameters of the meter. In such case a meter should be set to
default settings (from menu or via RS-485 interface). The message can be turned off by

pressing the button .
