The "IEC 61000-2-4 Watchdog" App

Standard IEC 61000-2-4 specifies numerical compatibility levels for industrial and non-public power distribution systems at rated voltages up to 35 kV. To ensure faultless functioning of the installed system, it requires that the power quality in all critical technical systems be monitored continuously in accordance with standard IEC 61000-2-4.

Brief Description

Once the "IEC61000-2-4" app is installed on your Janitza meter, you will be able to view reports created using standard IEC61000-2-4. The reports allow you to check the power quality and react to possible deviations on an ongoing basis.

Key Features:

• Integrated watchdog functionality according to standard IEC 61000-2-4.
• Daily or weekly reports are possible.
• No need to transfer large amounts of measurement data from the measurement device to the host system.
• Enables customization of the settings for your electrical network and class.
• Simple analyses with integrated traffic light principle.
• Savings in communication costs to remote applications.
• Execution of PQ analyses possible without special knowledge of power quality.

INFORMATION: The auxiliary voltage of the device must be buffered so that voltage breakdowns can be reliably detected as events.

Integrating the Power Analyzer in GridVis

Integrating the Power Analyzer into the GridVis evaluation and configuration software requires that an Ethernet connection to the device be established and the device TCP/IP address be specified.

• Establish a connection between the PC and the device using a direct connection or via a switch/router (see connection examples). We recommend using at least CAT5 cable.
• Specify or set the addressing mode ("Fixed IP" or "DHCP"). Set the device TCP/IP address if the "Fixed IP" mode is selected.

Connection Examples:

• Direct connection between UMG and PC: Both devices require a fixed IP address. A twisted pair patch cable (cross patch cable) is used.

  Fig.: Direct connection example

• Setup via a switch: UMG and PC require a fixed IP address. Connection is made via a switch and patch cables.

  Fig.: Setup via switch example

• Integration in a network with a DHCP server: The UMG and PC are automatically assigned the IP address by a DHCP server.

  Fig.: Integration via DHCP server example

Fixed IP Address

In simple networks without a DHCP server, the network address must be set directly on the device.

For a PC-UMG direct connection, please note:

• Use a twisted pair patch cable (cross patch cable).
• The first three segments of the IP address should be the same on the device and the computer. The last segment must be different! The subnet mask must match in all four blocks.

Example:

IP address of the computer: 192.168.000.020 with the subnet mask: 255.255.255.0

IP address of the UMG: 192.168.000.021 with the subnet mask: 255.255.255.0

DHCP Mode

With DHCP, fully automatic integration of a UMG into an existing network is possible with no additional configuration. At startup, the UMG automatically obtains the IP address, the netmask and the gateway from the DHCP server.

ATTENTION: Material damage due to incorrect network settings. Incorrect network settings can cause faults in the IT network! Consult your network administrator for the correct network settings for your device.

Integrating a UMG 604-Pro and UMG 605-Pro

• Set the device to programming mode. To do so, press buttons 1 and 2 simultaneously for about 1 second. If the password request is deactivated, the programming mode is then started and indicated with the text "PRG". The first digit of the address blinks.
• Set the address to 205 to select "DHCP mode" (=2) or "Fixed IP address" (=0).
• To do so, use button 2 to set the first digit to the value 2. Then use button 1 to go to the second digit and set it to the value 0 using button 2. Set the third digit to the value 5 in the same manner.
• Once the address is set, go to the parameter using button 1. Use button 2 to set the parameter to the corresponding value (see the "Addressing mode" table).
• For further settings, press button 1 to return to the input of the next address.
• If no button is pressed for approx. 60 seconds, or if buttons 1 and 2 are pressed simultaneously for approx. 1 second, the programming mode is exited and the device returns to the display mode.

Addressing Mode Table:

If "Fixed IP address" is selected, additional network parameters must be set:

• Setting the device IP address: Enter the programming mode. Set the address to 300 as described and set the first block of three of the device IP address (see IP addresses table). Then set the address to 301 and assign the second block of three of the device IP address. Complete the entries using addresses 302 and 303.
• Setting the subnet mask: Proceed the same way as for the device IP address settings to set the subnet mask using addresses 304 to 307 (see IP addresses table).
• Setting the default gateway: Proceed in the same way to set the IP address of the default gateway (if present) using the addresses 310 to 313 (see the IP addresses table). Note: Normally, no gateway setting is necessary for the configuration!

Read out the device address when "DHCP mode" is selected:

• Enter the programming mode as described. Use buttons 1 and 2 to set the address to 300 and note the block of 3 in the content area. Carry out this step analogously for addresses 301 to 303 (see table under step 10).

IP Addresses Table:

If the DHCP mode is deactivated ("off"), further network parameters must be set:

• Setting the device IP address: Select the "Address" item using button 3 or 4 and open it using button 6. Change the first digit of the address using button 3 or 4. Then use button 5 to go to the second digit and set it in the same way as above. Complete the IP address and confirm the entries with button 6.
• Setting the subnet mask: Select the "Netmask" item using button 3 or 4 and open it using button 6. Proceed the same way as for the device IP address settings to set the subnet mask.
• Setting the default gateway: Select the "Address" item using button 3 or 4 and open it using button 6. Proceed in the same way to set the IP address of the default gateway (if present). Note: Normally, no gateway setting is necessary for the configuration!

Reading out the device address:

• Open configuration menu from the home display using button 1 ("ESC"). Use button 3 to go to the item "Communication" and open it using button 6.
• Make a note of the addresses found under "Address" and "Netmask".

Setting the IP Address of the Computer for a Direct Connection

Usually, PCs in a company network are operated with DHCP. If you want to assign a fixed IP address for the PC (e.g. for a direct connection between PC and UMG), please proceed as follows:

ATTENTION: Material damage due to incorrect network settings. Incorrect network settings can cause faults in the IT network! Consult your network administrator for the correct network settings for your device.

INFORMATION: The auxiliary voltage of the device must be buffered so that voltage breakdowns can be reliably detected as events.

• Open the Network and Sharing Center in the Control Panel.
• Open the status window via LAN Connection (Fig. Network and Sharing Center).
• A fixed IP address for the PC can be assigned via Properties (see Fig. Procedure for setting a fixed IP address under Windows 10).
