Added value with additional functions
The UMG 511 power quality analyser serves for the purpose of continuous monitoring of the power quality e.g. in accordance with EN 50160. This serves for the purpose of monitoring the supply power quality
from the energy supply side. The UMG 511 can also be used in applications for failure analysis on the consumer side and is also used as a preventative measure for network perturbations. A rapid, cost-optimised and
reliable communication system can be developed through the Ethernet connection. The instrument’s own
homepage offers you the opportunity to call up the data or configure the instrument directly using the embedded web server.
The large number of digital inputs and outputs offer a variety of
communication systems possibilities and allows connection to
PLC systems and independent control tasks. The GridVis
analysis software represents a fundamental part of the standard
delivery. The GridVis can be used to practically trigger analysis
in accordance with EN 50160 with the click of a button. The
presentation of online data and the analysis of historical data is
also a benefit for finding the root cause of network problems.

Applications
The power quality analyser which is equipped with 4 current and voltage inputs collects and digitalises the
effective values (True RMS) from currents and voltages in 40-70Hz (15-440Hz) networks. The integrated
microprocessor calculates the electrical parameters from the sampling values. The relevant voltage can be defined as a phase-neutral or a phase-phase voltage for measurement in a three-phase system. The voltage serves the UMG 511 as a reference voltage for harmonic measurement, transient and event recording and for
the flicker meter. A nominal current can be set using this for the measurement of electrical current events.
The 4th current and voltage input represents a separate measurement system. However, it is generally used
for measuring the current in the neutral or PE conductor or used for measuring a voltage difference between
N and PE.

Display examples
The backlighted graphical display (5,7“) of the UMG 511 enables the presentation of measurement values in numerical form, as a bar chart
or as a line graph. Selected displays can automatically be displayed in alternation (automatic display rotation). The instrument is programmed using userfriendly clear text menus or the GridVis software.
Example of a UMG 511 connection illustration
Main measurement
Measurement in a four-phase network with main
measurement and auxiliary measurement
The UMG 511 has 4 measurement channels for
current and voltage. The first three channels
(main measurement) are intended for use in a
three-phase system.
Auxiliary measurement
The auxiliary measurement can be used for measurement in a single-phase or symmetrical threephase system. Alternatively, the current input
can be allocated to the three-phase system of the
main measurement for measuring the neutralconductor current. For example, the voltage
input could then be used for recording the voltage between the neutral conductor and PE. The
auxiliary measurement provides all measurement parameters like in the main measurement
(current, voltage, power, harmonics, transients,
events and flicker).

Digital inputs and outputs
The 8 digital inputs of the instrument can either be used for tariff switchover, for synchronisation, to start the recording, or as datalogger
for other meter inputs for pulses. There are 8 programmable comparators available which can be allocated up to 4 measurement parameters
as a limit value comparator. The digital outputs can also be programmed as a signal output for transients, events or as a pulse output.
Interfaces
RS485 protocols: Profibus DP or Modbus / RTU, Modbus-Gateway and BACnet
Fast Ethernet 10/100Base-TX protocols: HTTP, NTP, Modbus TCP, Modbus over TCP, DHCP und BACnet.
The measurement values and recorded data can be called up using the Ethernet (TCP/IP). Parameterisation of the instrument and analysis
of the data is undertaken using GridVis software included in the delivery. The actual measurement values can be read out using the various
field bus protocols (Modbus/RTU, Modbus/TCP, Profibus). An content of the digital inputs and outputs can be used for various.
Data collection and recording
The UMG 511 has an internal 256 MB flash memory for continuous recording of all measured data. The measurement value memory is
freely configurable with reference to the measurement values which are to be recorded and the recording intervals. The recording interval is
also the average time of the respective measurement value. In addition, the highest and lowest actual values (200ms average time) can also
be recorded within the interval if you want to save the data as a graph y(t). Obviously it is also possible to store the measurement data in
form of histogramms (distribution curve).
The recording of transients and events is initiated by triggers. Transients are recorded from a period larger than 50µs. Events such as excess
currents or under/overvoltage can be safely recorded from half a period. Events are recorded with up to 16000 (programmable) half cycles
as effective value recorder.

UMG 605: the extra compact power analyser
Added value through additional functions
Thanks to state-of-the-art digital signal processor, it is possible to offer the
power quality analyser UMG 605 at a very reasonable price. The high sampling rate enables a continuous measurement of more than 2000 measured
values per measurement cycle (200ms). The UMG 605 power quality analyser serves the purpose of continuous monitoring of the power quality e.g.
in accordance with EN 50160. This serves the purpose of monitoring the
supply power quality from the energy supply side. The UMG 605 can also
be used in applications for failure analysis on the consumer side and is also

DIN rail mounting (6TE): reduction of installation costs
Measurement equipment is usually installed in the low voltage main
distribution as an integral measurement instrument for the switchgear cabinet door. Installation and connection costs are significantly reduced by the installation of the UMG 605 on a 35mm
DIN rail. This means that the panel cut-out and wiring to the cabinet door is no longer necessary. In order to make use of the extensive functions of modern measuring equipment, the
interconnection and central analysis of the data plays an important
role. This means that the on-site display generally serves the purpose of the initialisation and service only.
The decidedly compact UMG 605 is suitable for installation in low
voltage main distribution panels and machines as well as in installation distribution boards which is particularly of interest for applications in building services engineering, information technology
and data centres.
Modern communication architecture
through Ethernet: affordable, rapid and
safe communication
Modbus gateway: the affordable
connection of units without an
Ethernet interface
The costs for installation and communication (e.g. periphery for field
buses) often surpass the costs of the measurement devices.
By connecting the equipment to an existing Ethernet system, a fast,
optimally priced and reliable communication system can be developed. Additional interfaces allow the integration of power analysers in
PLC systems or in central building management systems. The use of
open architecture offers the user a high amount of flexibility.
With the Modbus gateway function, simple Modbus RTU-units can
be connected to the Ethernet using the UMG 605. For example, the
UMG 605 can be used simultaneously as a gateway for subordinate
measurement points or older units which already exist in the installation. Each unit with a Modbus RTU interface, where the data format
and function codes match up, can be connected. Data can be marked
and scaled.
High-speed Modbus
The device of the UMG 605 series can transfer data between the units using the RS485 interface
at a speed of up to 921.5 kB/s.
The e-mail and homepage inform you
wherever you are…
Who hasn’t experienced it before? You are hardly through the door and
the telephone is already ringing. There are problems in production,
computers are crashing and the energy supplies are lost.
You have direct access to the extremely high performance homepage of
the UMG 605 with a web browser and an IP address. Extensive information is already available to you on the homepage. Online data are
available together with historical data and graphs recording events. The
homepage can be used to directly convert the rates into costs and be exported as a csv file or printed. As an alternative, you can let yourself be
informed by e-mail anywhere in the world if your energy supply becomes overloaded, if short-term interruptions to the voltage supplies
bring your production processes to a standstill or unauthorised harmonics reduce the lifespan of equipment. The application possibilities
are endless.

GridVis Software
Software
The GridVis software is included in the standard content of delivery of the UMG 511 and UMG 605 measurement devices. The software
helps you to read out and graphically present measurement data either online as actual values or from the measurement value memory. The
data can be displayed as a line graph, bar chart or histogram. The EN 50160 and EN 61000-2-4 analysis tools allow the rapid analysis of
both standards. At a glance, it is easier to identify whether the standards are fulfilled throughout the respective measurement period and a
copy can be directly created on paper or as a PDF document.

Visualisation, topological view
GridVis allows an individually adaptable visualisation of online data. The topological view provides a rapid overview of energy distribution
with the possibility of localising power faults by comparing the individual measurement points and by offering the possibility to monitor the
defined tolerances at a glance.
Customer specific solutions can be quickly and simply implemented through uploading of graphic documents (standard formats such as JPG)
with circuit diagrams, production lines or construction plans and incorporating the respective measurement units by drag and drop into their
actual locations. Limit value excesses (e.g. THD-U is too high) and the status of inputs and outputs can also be displayed.
Online values and analysis
of historic data
With the graphic line writer function, GridVis enables
rapid online presentation of the selected measurement values. In this function, the graph is continuously expanded
with new measurement values. For example, load profiles
can be presented through the analysis of historic data in
order to produce exact consumption analysis for optimised
electricity supply contracts. Fault analysis through the comparison of various parameters can also be achieved with a
few mouse clicks.
Graphic programming
The graphic programming option for user programs is completely new in the field of digital power analysers. Programs
specific to the application can be created with this method
such as the free programming of inputs and outputs, monitoring of processes or the issue of reports when defined limit
values are achieved. In addition to the operator-friendly graphic programming, the user is also free to program the Jasic®
source code directly.
programming language
The Jasic® programming language offers brand new opportunities. The user is no longer tied to the functions
which are fixed integrations in the unit; the unit can be expanded to include more functions. Up to seven of these
freely definable user programs can be processed simultaneously in the UMG devices.
