Janitza electronics
The story

For 50 years the German company Janitza electronics

has been active in the eld of manufacturing systems
for efcient power application, energy measurement and
cost savings.
Janitza is active throughout the world as a manufacturer
of measurement technology, class A network quality
analysers, energy management systems, digital
integrated measurement devices, mobile network
analysers, reactive power controllers, harmonic lters
and compensation systems.
Our customers appreciate the range of products and
solutions for modern energy management (e.g. EN 16001 /
ISO 50001). Due to the scalability of the products and
solutions an energy management system from Janitza
can be introduced step-by-step.
Janitza stands for the highest quality standards, a high
degree of innovation and products developed to reect
the latest knowledge and standards, manufactured with
the most up-to-date production technology.
The regional know-how of our sales engineers provides guidance and concept development through to the

commissioning of tailor-made solutions. After commissioning we provide support with maintenance and
system support. The regular training courses provide our
customers with secure insight into the topics of energy
management and network quality as well as our products
and system solutions.

Chapter 01
The customers

The customers

Janitza electronics GmbH products are generally of

interest to all professional consumers of electrical energy.
The products from Janitza electronics are already used
by 17 companies which are listed in the German Shares
Index (DAX). The most important customers are in the
automobile industry, the banking and insurance sector
or local councils. The products are used in industry,
commercial buildings, by energy suppliers, in airports,
supermarkets, universities and in hospitals. However,
the use of our products is also lucrative for smaller
companies.

The possibility of allocating energy costs to certain

products is becoming more and more important to
industrial companies. Janitza electronics also has
customised solutions for cost centre analysis.
The reduction of expensive peak demand loads and
the compensation of reactive power can immediately
cut down the electricity bill.

Janitza electronics GmbH has an export ratio of

approximately 50% and markets its products in more than
60 countries throughout the world.

The focus
Janitza electronics GmbH is a leading global manufacturer in the eld of digital integrated measuring equipment for energy distributors, energy optimisation
systems and power quality solutions. The products made
by Janitza electronics are generally used to reduce
energy, maintenance and products costs.
Awareness of power quality has gained signicance
in all companies in the past years. Excessive power
quality distortion lead to increased wear and tear in all
electrical supply equipment and any connected electrical
and electronic loads and can lead even up to production
stoppages. Our measuring instruments therefore provide
essential information about insufcient power quality
and hence enable customers to take measures for the
improvement of power quality problems. This leads to a
longer lifespan for equipment and improved sustainability
of the respective investments.

Universal measuring instrument UMG 103

UMG 103 Universal measuring instrument

for DIN rail mounting

The UMG 103 is a very compact universal measuring

instrument for mounting on DIN rails. The compact
dimensions even enable installation in limited spaces such
as in installation sub-distribution boards. Installation and
connection costs are significantly reduced by mounting
the instrument on a 35mm DIN rail.
In order to make use of the extensive functions of modern
measuring instruments, the interconnection and central
analysis of data plays an important role. This is the
reason for not using a display; two LEDs show the current
operating status. The communication of measurement
data takes place through a very fast RS485/Modbus
interface.

Main features
Measurement in TN and TT networks
3 voltage measurement inputs (300V CAT III), 3 current
measurement inputs
Continuous scanning of the voltage and
current measurement inputs
High measurement accuracy,
effective energy class 0.5; U/I, 0.2%
Harmonic analysis up to the 25th order
Including GridVis software
RS 485 (Modbus RTU, slave)
Mounting on 35mm DIN rail
Suitable for integration in installation distribution panels

Applications
The UMG 103 is intended for the measurement and
calculation of electrical parameters such as current,
voltage, power, consumption or harmonics etc. in building
installations, on distribution panels, on circuit breakers
and on server racks. The UMG 103 is fixed into cabinets or
small installation distributors in any installation position.
The measurement values can be read out using the serial
interface. The highest, lowest and energy values are
recorded every two seconds in a non-volatile memory.

12

The UMG 103 performance level is usually sufficient

for sub-measurements in connection with higher
performance power analysers such as the UMG 604 or the
UMG 508 applied in more complex energy management
systems. In this case, the UMG 103 serves as data
measurement point which takes the measurement data
and passes it on to a higher-level point (master device).
Using power analysers such as the UMG 604 with an
integrated Modbus/Ethernet-gateway and integrated
web server, data are brought onto the Ethernet level
or are visualised on the homepage. Some examples of
applications are cost centre management systems in
office buildings, monitoring feeders to sub-distribution
panels, motor control centres or in IT and data centres.

The voltage measurement inputs are designed for the

measurement in low voltage networks in which nominal
voltages up to 300V against ground and surge voltages
up to over voltage category III can occur. The UMG 103
is mainly suitable for measurements in low voltage
networks because it takes the supply voltage from the
measurement voltage and a voltage converter would be
therefore necessary for HV grids.

UMG 104

UMG 104 More than just a Multimeter

The UMG 104 equipped with a 500 MHz DSP (digital

signal processor) is a very fast and powerful power
analyser. The continuous scanning of the 8 channels with
20 kHz per channel allows the recording of all electrical
parameters (more than 800 values), minimum - and
maximum - values, and the main power quality values
such as harmonics (up to the 40th, each phase with the
detection of direction).
Based on these data loss of production can be avoided,
concepts can be developed, such as the electricity cost
reduction programs, and measures introduced. And
finally the improvements can be monitored and recorded
with the UMG 104 as well.
Using modern communication architectures, the acquired
data are fed to a central location, in powerful databases,
stored centrally and made available for further processing

in an open architecture. The easy integration into an

existing building control system or PLC environment
extends the capabilities of the UMG 104.

Applications
Replacement of analogue and digital instrumentation
Consumption data collection and analysis (load
profiles)
Continuous power quality monitoring
Cost center management, i.e. breakdown of energy
costs, e.g. allocation per product
Remote control and monitoring of equipment and
processes
Protection of networks
Sensor for building management systems or PLC

Cost-effective, fast and safe communication

Modbus and Probus
In many cases the costs for installation and communication
(e.g. peripheral equipment for field buses) exceed those
for the respective power meters. Integration of the UMG
104 in an existing field bus architecture means a fast,
cost-efficient and reliable communication. Additional
interfaces enable the integration of the power analysers
into PLC or building automation systems. The use of open
standards offers great flexibility to the user.

The UMG 104 can accept up to 4 current and 4 voltage

inputs, which allows monitoring of up to 4 single phase
circuits. Potential applications include data centers,
ofce buildings, motor control centers, etc.

Easy integration of devices with Ethernet

interface
With the Modbus interface function of UMG 104 you
can connect via Modbus gateways (for example UMG
508, UMG 604, ...) to Ethernet. Each instrument with a
Modbus RTU interface can be connected, if its data format
and function codes correspond. Data can be scaled and
labelled.

Highspeed Modbus
The devices of UMG 104 series can transfer data via
RS485 interface with a speed of up to 921,6 kB/s among
each other device of this series.

UMG 604 High performance power analysers

High performance power analysers from the UMG

604 product family are suitable for use at all network
levels. The high scanning rate enables a continuous
measurement by gathering more than 800 measurement
parameters. Due to the very high performance level of
the digital signal processor, all important power quality
parameters are recorded e.g. short-term interruptions
with fault recorder function, transients, harmonics up to
a 40th and starting current etc. Extensive communication
options e.g. Ethernet (TCP/IP), BACnet, Modbus, Profibus,
RS232, RS485, HTTP, FTP, SMTP, SNTP, SNMP or DNS
allow affordable and quick integration in the existing
communication architecture. Worldwide access to the
embedded web server can be gained through a web
browser e.g. for energy consumption analysis. Programs
specific to the user can be created with implemented
graphic programming. It is possible to run 7 user
programs simultaneously.

Areas of application
For measuring, monitoring and checking electrical
parameters in energy distribution units
Consumption data collection and analysis (cost centre
data collection)
For monitoring the power quality (harmonics, short
term interruptions, transients, initial current)
Measurement value generator for building
management systems or PLC
Control tasks e.g. depending upon the achieved
measurement values or limit values

UMG 604 the extra compact power analyser

Added value through additional functions

Through the integration of various functions, the UMG

604 power analyser goes far beyond the limits of digital
multifunctional measuring equipment and, therefore,
offers the respective added value. The UMG 604 and the
use of state-of-the-art processors allow to offer a very fast
and extremely compact power analyser at an affordable
price.

The UMG 604 contains the following functions:

Main features
Continuous measurement
Collection of all relevant power quality parameters (harmonics,
short-term interruptions, unbalance ...)
Ethernet and embedded web server
Jasic interpreter
Up to 7 user defined programs
GridVis software - full version included in the delivery

Applications
Major increases of energy costs make electrical energy a
driving force in costing. With the UMG 604, you can make
the first step towards better cost efficiency. The precise
collection of all energy data and electrical parameters
ensures the necessary amount of transparency in your
energy supplies. Concepts can be developed on the
basis of the data e.g. electricity cost reductions and the
introduction of measures. These targeted improvements
can also be monitored and recorded with the UMG 604.
The UMG 604, equipped with a 500 MHz DSP (digital
signal processor), is a fast and high performing power
analyser. The continuous scanning of eight channels

24

with 20 KHz per channel enables the collection of all

relevant electrical parameters (more than 800 values),
minimum and maximum values, the basic power quality
values such as harmonics (up to the 40th, each phase
with direction recognition) and short-term interruptions.
Even fast transients (> 50s) can be safely identified.
Using modern communication processes, the collected
data is conducted to a central location, stored centrally
in a high-performance database and provided for further
processing in an open system. Simple integration in an
existing building management system control or PLC
environment expands the areas of application of the UMG
604.

DIN rail mounting (6 units):

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 604 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 604 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.

Ethernet/Modbus gateway: the affordable

connection of units without an Ethernet interface
With the Modbus gateway function, simple Modbus RTUunits can be connected to the Ethernet using the UMG 604.
For example, the UMG 604 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.
Highspeed Modbus
The devices of the UMG 604 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 hasnt 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 604 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 unauthorized harmonics reduce the lifespan of
equipment. The application possibilities are endless.

Modern communication processes through the

Ethernet: affordable, rapid and safe communication
The costs for installation and communication (e.g.
periphery for field buses) often surpass the costs of the
equipment.
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
clear standards offers the user a high amount of flexibility.

Residual current measurement (RCM)

Functionality
All lines on the output to be monitored are fed through
the current transformer, with the exception of the PE line.
If the system is operating correctly, the sum of all currents
is equal to zero so that no voltage is induced in the current
transformer. In the event that a fault current flows via
ground or other channel, the current difference induces
a current in the current transformer which is captured by
the residual current measurement device.

UMG 604D
The UMG 604D monitors the residual currents of pure
alternating currents in TN and IT networks in electrical
systems, displays the current value and issues a warning
if the limit values are exceeded.
In addition to the operating currents L1-L3, the fourth
measurement input for residual current measurement is
coloured differently (light grey) and suitable for currents up
to 30 mA. The current transformer with a transformation
ratio of 600/1A and sufficiently-dimensioned internal
dimensions (20x30, 50x80 or 80x120mm) can be found in
section 6, page 166.

graph.
The topology gives a quick overview of
the energy distributions and the possibility
to locate power failures by comparing
measuring points and checking the defined
tolerances at a glance.

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
check 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 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 unit.

UMG 605 power quality analyser

(EN 50160, IEEE 519, ITIC)

The UMG 605 power quality analyser is particularly

suitable for monitoring power quality according to
standards such as the EN 50160. All power quality
parameters are collected and analysed e.g. flicker, shortterm interruptions with fault recorder function, transients,
harmonics up to 63rd and inrush currents etc. Extensive
communication possibilities e.g. RS 485 Modbus, Profibus,
Ethernet (TCP/IP), BACnet, HTTP, FTP, SMTP, SNTP, SNMP,
DNS .... allow cost effective and rapid integration in
existing communication networks. Worldwide access to
the embedded web server can be gained through a web
browser. The GridVis software included in the content of
delivery allows extensive analysis just with the click of a
button.

Areas of application
Continuous monitoring of the power quality e.g.
EN 50160
Ethernet gateway for subordinate measurement points
Analysis of electrical faults for network problems
Monitoring of the internal distribution network
according to EN 61000-4-7, 4-15, 4-30
Report generator for EN 50160 analysis
Control tasks, e.g. depending on achieved measured
values or limits
Transducer for building automation or PLC systems

Power quality analyser UMG 605

UMG 605 the extra compact power quality 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 used as a
preventative measure for network perturbations.

Main Features
Measurement of power quality according to DIN EN 61000-4-30
Measurement method class A
Fourier analysis 1st to 63rd harmonics for U-LN, U-LL, I, P
(consumption/supply) and Q (ind./cap.)

4 voltage measuring inputs, 4 current measuring inputs

Programming of customer specific applications in Jasic

Continuous sampling of the voltage and current measuring

inputs with 20kHz

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

34

serves the UMG 605 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.

UMG 96L / UMG 96 Universal measuring instruments

Digital diversity versus analogue simplicity

Universal measuring instruments of UMG 96L and UMG

96 product families are mainly designed for use in low
and medium voltage distribution systems. Due to the
large number of available measurement values in an
extremely compact measuring unit, a number of analogue
measurement instruments can be replaced and, therefore,
installation costs can be reduced. Additional functions
such as the recording of minimum and maximum values,
the operating hour meter, the bi-metallic strip function,
password protection and many more offer a significant
amount of added value. The high measurement accuracy
and a large LCD-display means universal application
possibilities and offer fundamental advantages in
comparison to analogue measuring instruments.

Areas of application
Replacement of analogue measurement instruments
Display and control of electrical parameters in energy
distribution systems
Cost centre data collection
Measurement value generator for building
management systems or PLC
Limit value monitoring

Chapter 02
Universal measuring instruments UMG 96L/UMG 96

UMG 96L/UMG 96 Universal measuring instruments

96x96 mm front panel mounting

The use of energy measurement technology in energy

distribution has moved dynamically towards digital
universal measuring instruments in the past few years.
The advantages are obvious: lower equipment costs for
more information and functionality. In addition, digital
measuring technology is more accurate, even all along
the entire lifespan.
Clear cost advantages also result from the construction
of the switchgear which results in lower installation
costs and less wiring efforts in comparison to analogue
measuring technology. Universal measuring instruments
of the UMG 96L and UMG 96 product families are mainly
designed for use in low and medium voltage distribution
systems.

Main features
Compact housing dimensions (96x96 mm), minimal
installation depth
User-friendly and reliable terminals
Large LCD with outstanding legibility
The large quantity of electrical measurement values,
replaces 13 analogue measurement units and more

In addition to the large quantity of electrical measurement

values, this series also offers a number of additional
functions such as the recording of minimum and maximum
values, the operating hour meter, the bi-metallic strip
function, password protection and many more.

Excellent reliability and long life span

Applications
The UMG 96L and UMG 96 measurement instruments
are digital front panel mounted measuring instruments
which are suitable for measuring and recording electrical
parameters (True-RMS) in 50/60 Hz networks. The
measurement is configured for three-phase systems with
a neutral conductor (TN and TT networks). At the network
frequency of 50 Hz or 60 Hz, the scanning frequency of the
random measurements which take place once per second
is 2.5 kHz or 3.0 kHz. The supply voltage and scanning
frequency for operating the UMG 96L is taken from the
L1-N measurement voltage. The effective values and
the minimum and maximum values are recorded every
15 minutes and the programming data is immediately
40

stored in a non-volatile memory (EEPROM). The main

characteristic of the measurement instrument is the
compact construction (96x96 mm) and the high level of
stability.
In order to achieve the functional diversity of the universal
measurement instrument, you would need 13 analogue
units such as an ampere meter, volt meter, volt meter
switch, power meter (kW, kVA, kvar, cos ), an effective
and reactive energy meter (kWh/kvarh) and a frequency
meter. This means that the planning, installation, wiring
and storage costs are significantly reduced in comparison
to the use of analogue measuring instruments. Another
advantage is the higher precision and better legibility.

Chapter 02
Universal measuring instruments UMG 96L / UMG 96

Measurement value displays

The extremely legible LCD display in connection with
the function keys informs the user about the selected
measurement values (actual, low, high and average
values).Three measurement values can be simultaneously
displayed in the LCD data field. The contrast of the LCD
display can be adjusted by the user.
Display selection and automatic display rotation
All measurement values can be called up in the initial
delivery status. Measurement values which are not
required can be hidden and displayed again when
necessary. A cycle between 1 and 250 seconds can be set
for the automatic display rotation. The display rotation
function can also be deactivated.
Display examples

Operating hour meter

The operating hour meter is immediately activated when
the unit is switched on and can not be reset. The time is
recorded at a 15 minute resolution and is displayed in
hours.
Digital outputs for effective or reactive energy
consumption or limit values
Digital outputs can be used as pulse outputs for the
effective or reactive energy consumption or as switch
outputs. The digital outputs can be programmed in
order to monitor the measurement data. The transistor
output can also be linked with the measurement value
of the limit value by programming which is activated if
the value is not achieved or is exceeded. The transistor
output is suitable for controlling electrical devices with a
DC operating voltage or units with NPN inputs e.g. PLC.
Password
The user can protect programming and configurations
against unauthorised changes with a 3-digit password.

UMG 96S

UMG 96S Universal flush-mounting measuring instrument

Universal flush-mounting measuring instruments of the

UMG 96S product family are mainly designed for use in
low and medium voltage distribution systems. Due to
the large number of available measurement values in an
extremely compact measuring unit, a number of analogue
measurement instruments can be replaced. Additional
functions such as the measurement of harmonics, the
recording of minimum and maximum values, digital and
analogue I/Os, the operating hour meter, the bi-metallic
strip function, password protection and many more offer
an effective tool for fault analysis and for monitoring
power quality. The interface and field bus features
(Modbus, Profibus, M-bus) enable communication of
the measurement data and incorporation into extensive
energy management systems.

Areas of application
Display and control of electrical parameters in energy
distribution systems
Cost centre data collection
Limit value monitoring (e. g. over voltage, energy
consumption)
Monitoring of harmonics

UMG 96S with interface and field bus

Entry level in intelligent energy management systems

The use of energy measurement technology in energy

distribution has moved dynamically towards digital
universal measuring instruments in the past few years.
The advantages are obvious: lower equipment costs for
more information and functionality.
In addition, digital measuring technology is more accurate
even all along the entire lifespan. Clear cost advantages
also result from the construction of the cabinet which
results in lower installation costs and less wiring efforts
in comparison to analogue measuring technology.
Universal measuring instruments of the UMG 96S
product family are mainly designed for use in low and
medium voltage distribution systems. In addition to the
large quantity of electrical measurement values, this

Applications
The UMG 96S is a measurement instrument which
is suitable for measuring, recording and monitoring
electrical parameters (True-RMS) in low and medium
voltage networks.
The measurement is suitable for 1 and 3-phase systems
with a neutral conductor in low and medium voltage
networks. One of the characteristics of this measurement
instrument is the compact construction (96x96 mm) and
the measurement of harmonic currents and voltages in

series also offers a number of additional functions such

as the recording of minimum and maximum values,
the operating hour meter, the bi-metallic strip function,
password protection and lots more. The possibility for
communication through various field buses enables
incorporation in more complex energy management
systems as well as the connection to PLC controls or
central building control systems. Integrated harmonics
analysis becomes more significant with increasing
network pollution (increasing THD-U values).

each conductor. In order to achieve functional diversity of

the universal measurement instrument, you would need
around 15 analogue units such as an ampere meter, volt
meter, volt meter switch, power meter (kW, kVA, kvar, cos
), an effective and reactive energy meter (kWh/kvarh),
a harmonic analyser and a measurement converter. This
means that the planning, installation, wiring and storage
costs are significantly re
duced for the UMG 96S in
comparison to analogue measuring instruments.

Chapter 02
Universal measurement instruments UMG 96S

Data storage / memory

Up to 160,000 measurement values or events can be
stored in the onboard memory (option). Four predefined
profiles can be used for the storage of measurement
values and events. Each of these profiles can be selected
individually or together with other profiles.
Rotary field display

The basic UMG 96S without memory and clock only

stores the consumption (overall) and minimum/maximum
values (without time stamp).

Measurement value displays and automatic display

rotation
The measurement values are calculated once per second
and can be called up in the measurement value displays.
Two methods are available for calling up the measurement
values:

THD L3 highest value

An automatically changing presentation of selected

measurement value displays with a settable change over
time of 0...60 seconds
The selection of the measurement value display using
the keys for a preselected display profile.

Programming Current transformer

There are four display profiles available and each profile

can be configured using the PC, specific to the customer
needs, and be transferred to the unit.

LCD contrast
The contrast of the LCD display can be adapted by the
user. In order to achieve the optimum contrast throughout
the full operating temperature range, an automatic
contrast setting takes place using the measured inside
temperature.
Operating hour meter
The operating hour meter measures the time (6 minute
intervals) after the unit is ready for operation and
cannot be reset. In addition, 6 overall runtimes can be
programmed using the 6 comparator systems and the

Industrial data communications interface

and eld bus
In order to process and analyse the large quantities
of generated data, the data are transferred using
corresponding communication means and are centrally
collected. The incorporation of the UMG 96S in more
complex management systems and the connection
to PLC controls or central building control systems is
also possible. The UMG 96S thereby provides various
interfaces (RS232, RS485, M-bus) and protocols for the
configuration of the most common field buses (Modbus,
Profibus, M-bus). The UMG 96S is characterised by its
reliable communication and very high transfer rate.

Digital inputs/outputs
The digital outputs can be used as pulse outputs (max.
10 Hz) for the effective and reactive energy consumption
or as switch outputs. The digital outputs can be
programmed in order to monitor the measurement data.
Up to 3 comparators (A, B, C) can be allocated to each
digital output and the result is conducted to the digital
output. The comparator result can also be written from
externally through the Modbus RTU. The switch outputs
can also be set through the Profibus remote.

Analogue outputs
The product variants with analogue outputs can either be
configured as analogue outputs, pulse outputs or switch
outputs. The following parameters are available to each
analogue output: measurement value, scale start value
(4mA) and the scale end value (20mA).

Chapter 02
Universal measurement instrument UMG 96RM

Typical applications
In order to achieve a sustainable reduction in energy costs,
an overview of the energy consumption and the energy
flows in the electrical system is first required. Whether for
the build-up of energy management systems (ISO 50001/

EN16001), the cost centre management or the monitoring

of the power quality, the universal measurement devices
from the UMG 96RM range are the basis for every
application.

Energy data acquisition & load prole

With the help of the UMG 96RM detailed acquisition of energy data and
the load profile is a simple task within the scope of energy analysis.
This is essential for tracking energy efficiency and the safe design of the
energy distribution systems.

Cost centre analysis

It is becoming more and more important in industrial enterprises to
be able to assign energy costs to particular products and to be able to
determine the breakdown and allocation of energy costs to charge them
to the individual processes and consumers. This also allows employees
to focus on specific cost optimisation and conservation of energy.

Energy management systems (ISO 50001/EN 16001)

Energy management systems per standard ISO50001/EN16001 are
essential for continuous improvements in energy efficiency and reduction
of costs. Universal measurement devices from the UMG 96RM range are
an important constituent part of energy management systems, which
can also secure tax breaks (e. g. in germany) amongst other benefits.

Transparency of energy supply

A higher degree of transparency can be attained through a multistage and scalable measurement system within the scope of energy
measurement technology. Only by means of continuous measurement
with high resolution meters, sporadic events can be analysed and
corrective solutions identified.

Power quality monitoring

The UMG 96RM gives indispensable information about insufficient
power quality and enables measures to be undertaken to address
grid problems. This result is the prevention of production drop-outs,
significantly longer service life for the manufacturing resources and thus
an improved sustainability for the investment associated with them.

UMG 503 Digital measurement

Power analysers of the UMG 503 product family are mainly

designed for use in low and medium voltage distribution
systems. The large display in 144 x 144mm housing, the
higher accuracy level and the extended measurement
range allows universal applications. Additional functions
such as the measurement of harmonics, the recording
of minimum and maximum values, the relay outputs,
pulse and analogue outputs, the bi-metallic strip function,
password protection and many more offer an effective
tool for fault analysis and for monitoring power quality.

Areas of application
Measurement, monitoring and controlling of electrical
parameters in energy distribution systems
Recording of load profiles for energy management
systems
Collection of energy consumption data for cost centre
analysis
Measurement value generator for building
management systems or PLC (Modbus)
Monitoring of harmonics, limit value monitoring

The interface and field bus features (Modbus) enable

communication of the measurement data and
incorporation in extensive energy management systems.
The integrated logic enables the analysis of measurement
data and the introduction of concrete measures.

UMG 503
The universal power analyser

The use of energy measurement technology in energy

distribution has moved dynamically towards digital
universal measuring instruments in the past few years.
The advantages are obvious: lower equipment costs for
more information and functionality. In addition, digital
measuring technology is more accurate, even all along
the entire lifespan.
Clear cost advantages also result from the construction of
the cabinet due to lower installation costs and less wiring
efforts in comparison to analogue measuring technology.
Universal measuring instruments of the UMG 503 product
family are mainly designed for use in low and medium
voltage distribution systems.

Main features
Large measurement and display range
A large display in 144x 144mm housing
RS232, RS485 interface
Field bus: Modbus
Harmonics display
2 relay outputs (mechanical relay)
Digital I/O and analogue outputs
Integrated logic for alarm signals
High reliability and long lifespan

Applications
The UMG 503 is a digital flush-mounted measurement
instrument which is suitable for measuring and recording
electrical parameters (True-RMS) in low and medium
voltage networks. The measurement is suitable for 1- and
3-phase systems with and without neutral conductors.
At a mains frequency of 50 Hz, the scanning frequency
of random measurements, which takes place twice per
second, is 6.4 kHz. It is characterised by the high accuracy
level, the compact construction and the measurement of
harmonics in each phase.

62

In addition to the large quantity of electrical measurement

values, this series also offers a number of additional
functions such as the recording of minimum and
maximum values, the bi-metallic strip function, password
protection and many more. Due to the large display, the
wide measurement range and the high accuracy level, the
UMG 503 power analyser is very popular in low voltage
main distribution panels. The possibility for communication through various field buses enables incorporation
in more complex energy management systems as well as
the connection to PLC controls or central building control
systems. The integrated harmonics analysis becomes
more significant with increasing network pollution
(increasing THD-U values).

In order to achieve the functional diversity of the universal

measurement instrument, you would need around 13
analogue units such as an ampere meter, volt meter,
volt meter switch, power meter (kW, kVA, kvar, cos ), an
effective and reactive energy meter (kWh/kvarh), a clock,
a frequency meter and a harmonic analyser. This means
that the planning, installation, wiring and storage costs
are significantly reduced for the UMG 503 in comparison
to analogue measuring instruments. Another advantage
is the more accurate and better legibility. Selected
measurement values and power failure/power return are
recorded in a ring buffer with time stamp.

Chapter 02
Power analyser UMG 503

Data memory
A ring buffer for 80,000 or 320,000 measurement values
(depending on the variant) is available for storing the
selected average values. With the factory settings, average
values of U1, U2, U3, I1, I2, I3, P1, P2 and P3 are stored
using an average time of 15 minutes for approximately 1
year for variants with 512 k RAM (approximately 3 months
for types with 128k RAM).
A total of six limit value windows for storing measurement
values can be programmed. The upper and lower limit
values can be freely selected. The recording can take
place within or outside of the range.

Measurement value displays and automatic

display rotation
The extremely well legible LCD data field in connection
with the function keys informs the user about the selected
measurement values (current, low, high and average
values). With the UMG 503, three measurement values
can be simultaneously displayed in the LCD data field and
up to 140 data fields can be individually designed with
the GridVis software. A cycle between 1 and 9999 seconds
can be set and a selection of measurement values can be
made.

Bi-metallic strip function

The bi-metallic strip function is recreated for the three
external conductor currents. These values can be
integrated in the stated times and be recorded as highest
average values.

Summer/winter time switch

The following options can be selected:

Power values and cos

a) No switchover
b) Own switchover point
c) EU listed switching

Interfaces
The communication interfaces of the UMG 503 which are
configured in accordance with the EIA RS485 standard
(half duplex) support the Modbus RTU in integer format.
The communication protocol can be selected by using the
menu.
In the Modbus RTU mode, baud rates from 9.6 kBit/s to
115 kBit/s are supported (depending on the design
version). The register addresses are available to the PLC
user in integer format.

UMG 505 Power analysis, LON and I/O-Vielfalt

Power analysers of the UMG505 product family are mainly

designed for use in low and medium voltage distribution
systems. Due to the additional communication options
using LON, this power analyser is often used in building
management systems. The large number of digital and
analogue inputs and outputs (4 DI, 5DO, 4AO) enables
the incorporation in monitoring systems, control tasks,
information reports, the communication of measurement
data (e.g. energy consumption) at a control point and
incorporation in an extensive energy management
system. Additional functions such as the measurement
of harmonics, the recording of minimum and maximum
values, pulse and analogue outputs, the bi-metallic strip
function, password protection and many more offers an
effective tool for fault analysis and for monitoring power
quality.

Areas of application

In addition to the large quantity of electrical measurement

values, this series also offers a number of additional
functions such as the recording of minimum and maximum
values, the bi-metallic strip function, password protection
and many more. Due to the LON field bus, the UMG 505 is
starting to find more applications in building services. The
large number of digital and analogue inputs and outputs
offers a variety of communication possibilities and allow
connection to PLC controls and independent control
tasks. The integrated harmonics analysis becomes more
significant with increasing network pollution (increasing
THD-U values).

Applications
The UMG 505 is a digital flush-mounted measurement
instrument which is suitable for measuring and recording
electrical parameters (True-RMS) in low and medium
voltage networks. The measurement device is suitable
for 1- and 3-phase systems with and without neutral
conductors. At a mains frequency of 50 Hz, the scanning
frequency of random measurements, which takes place
twice per second, is 6.4 kHz. It is characterised by the
high accuracy level, the compact construction and the
measurement of harmonics in each phase.

70

In order to achieve functional variety of the UMG 505, you

would need around 13 analogue units such as an ampere
meter, volt meter, volt meter switch, power meter (kW,
kVA, kvar, cos ), an effective and reactive energy meter
(kWh/kvarh), a clock, a frequency meter and a harmonic
analyser. This means that the planning, installation,
wiring and storage costs are significantly reduced with
the UMG 505 in comparison to analogue measuring
instruments. Another advantage is the more accurate and
better legibility. Selected measurement values and power
failure/power return are recorded in a ring buffer with
time stamp.

Chapter 02
Power analyser UMG 505

Measurement value displays and automatic

display rotation
The extremely legible LCD display in connection with
the function keys informs the user about the selected
measurement values (actual, low, high and average
values). With the UMG 505, three measurement values
can be simultaneously displayed in the LCD data field and
up to 140 data fields can be individually designed with
the GridVis software. A cycle between 1 and 9999 seconds
can be set for measurement value rotation and a selection
of measurement values can be made.
Memory
The memory of the UMG 505 is split into three areas: the
event memory, the lowest and highest memory and the
ring buffer.
Event memory
The following events can be stored in the event memory
with time and date:
Deletion of the event memory
Changes to the digital input
Failure and return of the auxiliary voltage
Failure and return of the measurement voltage

Up to a maximum of 9999 events can be stored. The data

can only be read out with the PC and the GridVis
software.

Ring buffer
The following can be selected for storage in the ring
buffer:
Average of measurement values
The fixed energy meters

When storing the average values of U1, U2, U3, I1, I2, I3,
P1, P2 and P3 using an average time of 15 minutes, the
memory is sufficient for a period of 1 year. A total of six
limit value windows for storing measurement values can
be programmed. The upper and lower limit values can
be freely selected. The recording can take place within or
outside of the range.

Summer/winter time switch

The following options can be selected:
No switchover
Own switchover point
EU listed switching
Weekly time switch
The time switch in the UMG 505 has 100 time channels.
Each time switch channel specifies a period of time. The
period of time is specified by the start-up point and the
switch off point. The start and stop points are defined by
weekdays, hour and minutes. Each time switch channel
can simultaneously control a time switch output and
select a consumption meter. A time switch output can be
allocated to a digital output when programming the
digital outputs.

71

Chapter 02
Scope of operation UMG 505

Pulse input
Digital input 4 can also be used as a pulse meter input for
the effective energy measurement (max 20Hz).
Digital inputs
The 4 optical coupler inputs are illustrated on the internal
inputs 1 to 4. The eight inputs from the LON bus interface
(option) are illustrated on the internal inputs 5 to 12. The
status of the digital inputs 1-4 can be called up using the
serial interface.
Each input channel can simultaneously switch a energy
counter and synchronise the internal clock.
Two of each of the digital inputs can be linked with each
other using AND. The results can be allocated to an input
channel. Each digital input 1 to 4 is allocated to an event
counter (1-3 max. 1Hz). If one of the digital inputs (1 to 4)
is allocated a function, with the exception of pulse value,
all changes are recorded with the date and time stamp in
the event memory.

Digital output
The UMG 505 has five digital transistor outputs. These
outputs are marked on the display with out1 to out5.
Each of these outputs can be allocated to a different data
source. There are up to 5 different data sources which can
be selected:
Limit value outputs
Times switch outputs
LON bus (option)
Energy meter
Each data source can only be allocated to one output. If
an output is allocated to a consumption meter, the output
works as a pulse generator.
The signals from all data sources (except the consumption
meter) can also be generated as inverted signals.

72

Pulse outputs
The five digital outputs in the UMG 505 can be assigned
as pulse outputs. The minimum pulse length is 50ms and
the maximum frequency is 10Hz.
Analogue outputs
The UMG 505 has 4 analogue outputs. The analogue
outputs have common ground and are galvanically
isolated from the other inputs and outputs in the UMG
505. An external auxiliary voltage of 20V to 30V DC is
required to operate the analogue outputs. The sources for
analogue outputs are:
Measurement values
Values which are sent to the UMG 505 through Modbus.

Interfaces
Depending upon the product variant, the UMG 505 is
equipped with an RS485 LON and/or an RS232 interface.
The RS232 interface serves as a peer-to-peer connection
e.g. as a connection between the UMG 505 and a laptop.
The protocol Modbus RTU is available through the RS485
which is used to network the UMG 505. The LON interface
is frequently used in central building control systems in
order to incorporate the UMG 505 in building automation.
Limit value monitoring
Five limit value outputs can be programmed to monitor
the measurement values. Each limit value output can be
allocated to up to 3 comparators (A, B, C). The following
can be programmed for each comparator:
2 limit values and 2 measurement values or
2 limit values and 1 measurement value or
1 limit value and the minimum start-up time
Any limit value violations established by a limit value
output is registered in the event memory with a record of
the time and can also be issued on a digital output.

UMG 507

UMG 507 Power analyser

Power analysers of the UMG 507 product family are

suitable for use at all network levels. The continuous
measurement enables the collection of various
measurement parameters, the identification of shortterm interruptions, a fault recorder function and harmonic
analysis. Extensive communication options e.g. Ethernet
(TCP/IP), Modbus, Profibus, RS232, RS485, HTTP, SMTP,
UTP or DNS allow affordable and quick integration in
existing communication networks. Worldwide access to
the embedded web server can be gained through a web
browser. This means that the extensive opportunities
offered by the UMG 507 are available without any
additional software. The large number of digital and
analogue inputs and outputs enable incorporation in
monitoring systems, control tasks, information reports,
the communication of measurement data (e.g. energy
consumption) to a central control point and incorporation

in extensive energy management systems. Nummerus

logic functions allow the analysis of measurement data
and the introduction of concrete measures.

Areas of application
For measuring, monitoring and control of electrical parameters
in energy distribution systems
For recording load proles (energy consumption) for energy
management systems (cost centre data collection)
For monitoring power quality (harmonics, short term
interruptions, inrush currents)
Control tasks e.g. depending upon the achieved measurement
values or limit values
Remote monitoring via onboard homepage

Chapter 02
Power analyser UMG 507

UMG 507
Multi-function power analyser

The use of energy measurement technology in energy

distribution has moved dynamically towards digital
universal measuring instruments in the past few years.
The advantages are obvious: lower equipment costs for
more information and functionality. In addition, digital
measuring technology is more accurate, even all along
the entire lifespan.
Clear cost advantages also result from the construction of
the cabinet which results in lower installation costs and
less wiring efforts in comparison to analogue measuring
technology. Power analysers of the UMG 507 product
family are designed for use at all network levels.

Main features
Continuous measurement
Data collection of short-term interruptions
Ethernet and embedded web server
Harmonics analysis
6 digital inputs, 6 digital outputs, 2 analogue outputs,
1 analogue input
1 temperature input
Integrated logic for control tasks and alarm signals
Modbus master, Ethernet / Modbus gateway

Due to the continuous measurement, short-term

interruptions are registered and the fault recorder
function provides more information about the event. A
rapid, cost-optimised and reliable communication system
can be developed through the Ethernet connection. The
instruments 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 and analogue inputs and outputs offers a variety of
communication possibilities and allow connection to PLC
controls and independent control tasks. The integrated
harmonic analysis becomes more significant with
increasing network pollution (increasing THD-U values).

Applications
The three-phase electronic measuring instrument collects
and digi
talises the effective values of currents and
voltages (True RMS) in a 50/60Hz network. The integrated
microprocessor calculates the electrical parameters
from the sampling values. All measurement values are
continuously measured and recorded at intervals of
200ms over 10 periods (50 Hz).
This allows the safe identification of short-term
interruptions with the fault recorder function. For shortterm events, the effective values are recorded over 128
periods with 64 pre-trigger periods and with the transient
memory over 5 periods with 2 pre-trigger periods.
The reaction time of the internal outputs is < 10ms and the
external bus outputs < 200ms.
78

Chapter 02
Power analyser UMG 507

GridVis software
The UMG 507 power analysers already contain the GridVis
software upon delivery. On one hand, this software
enables simple and complete parameterisation of the
respective measurement instruments and on the other
hand, can analyse the measurement value memory in
the unit. In GridVis, the data are stored in a database and
can be processed in MS Excel for example. GridVis also
allows online presentation of the measurement values.
More information is available in chapter 5 Software.
Embedded web server/e-mail
Worldwide access to the UMG 507 can be gained through a
web browser. In order to provide access, the web address
and access authorisations must be set up. The complete
parameterisation software is filed as an HTML page on
the flash memory. The open architecture of the UMG 507
allows the user to apply own ideas to design Java-Applets
and Active X-components and file them on the UMG
507. If limit value violations or events occur, they can be
automatically sent to the set up e-mail address. Data from
the memory storage can be sent by e-mail (attachment)
at preset times and processed with the GridVis software.
Protocols: HTTP, SMT, UTP, DNS, NTP, MOD TCP, Modbus
over TCP, DHCP/BootP.

Connection to an ISDN router / DSL router

The unit can be connected to the internet using an external
router (e.g. ISDN router or DSL router).
The SMTP authentication enables you to store mails on
the internet providers mailbox using the Plain/Login/
Cram-MDS (newest encryption methods).

Data collection and recording

The UMG 507 has an internal memory of 256 KB RAM
and, depending on the version, an additional memory of
16 MB flash is available for continuous recording of the
measured data. This measurement value memory can
be freely configured with reference to the measurement
values which are to be saved and the recording intervals.
In addition, the highest and lowest actual values (200 ms
average time) can also be saved within these intervals.
The recording of events is prompted by triggers. Events
such as excess currents, under voltage or overvoltage can
be safely collected from a half period duration. Events are
recorded over 128 periods as effective value recorders.

Transformer monitoring, k-factor

The maximum permitted current can be monitored in
transformers, fuses or motors by entering the k-factor. The
data from transformer manufacturers such as the current
and k-factor (1= 100%) can be programmed on the digital
output using the comparator. In addition, the temperature
input can be used for transformer monitoring.

can be collected using the temperature input. Any process

signals can be allocated to the analogue input.

Inputs and outputs

Depending upon the product variant, the UMG 507 has
a large number of internal digital and analogue inputs
and outputs (refer to design versions). The top versions
of the UMG 507 (AD, P, E and EP) have six digital inputs,
six digital outputs, two analogue outputs (0/4-20mA), a
temperature input and an analogue input (0/4-20mA). The
digital inputs can be used as pulse inputs, synchronisation
inputs or signal inputs. The digital outputs can be defined
as limit value outputs, pulse outputs, time switch outputs
or logic outputs. Both analogue outputs can be applied as
measurement value transducers or for analogue control
of generators (0-20mA). Transformer temperature data

Integrated logic
The 128 programmable logic links provide connections
between inputs and outputs, measurement values and
internal functions of the UMG 507. The standard operators
AND, NAND, OR, XOR, EQU, rising edge and falling
edge are available. The events are allocated to free flags
which can also be linked with other flags. The incoming
information through the Modbus RTU or the Profibus can
also be incorporated in the logic links.
Trigger events, the virtual weekly time switch channels
and Emax channels, the limit value comparator and
signals received through the field bus are available as
operands. These flags can then prompt the switchover
of digital outputs, tariff changes, measurement value
synchronisation, the time setting or the despatch of
an e-mail. Measurement values can also be added,
subtracted, multiplied or divided.

Modbus RTU master function / Modbus gateway

The RS485 of the UMG 507E/EP can
also be used as a Modbus RTU master.
This means that the measurement

Main features and customers benefit UMG 508

User-friendly graphical colour display with intuitive user interface

The high-resolution graphic display provides informative presentations
of line graphs, FFT harmonic as bar diagram, clear display of the kWhmonth values, alarm management/event viewer with dates and time
stamp, and many other features.
In addition to the information content the redesign of the UMG displays
focused very much on a user-friendly, self-explanatory and intuitive
operation of the UMG 508.

Modern communication architecture via Ethernet:

Cost-effective, fast and safe communication
In many cases the costs for installation and communication (e.g.
peripheral equipment for field buses) exceed those for the respective
power meters. Integration of the UMG 508 in an existing Ethernet
architecture means a fast, cost-efficient and reliable communication.
Additional interfaces enable the integration of the power analysers into
PLC or building automation systems. The use of open standards offers
great flexibility to the user.

Modbus Gateway:
Easy integration of devices without Ethernet interface
With the Modbus Gateway function of UMG 508 you can connect less
sophisticated Modbus RTU meters to Ethernet.The UMG 508 can be used
simultaneously as a gateway for sub-meters or prior instruments existing within the installation. Each instrument with a Modbus RTU interface
can be connected, if its data format and function codes correspond. Data
can be scaled and labelled.

Highspeed Modbus
The UMG 508 series can transfer data via RS485 interface with a speed
of up to 921.6 kB/s among each other device of this series.

Alarm management:
E-mail and homepage inform you, wherever you are...
Who would not agree? Just leaving the building the first call arrives
about certain problems in production, computer failure, energy
breakdown...

UMG 511

UMG 511 Class A power quality analyser

according to IEC 61000-4-30

The UMG 511 power quality analyser is particularly suitable

for monitoring power quality according to standards such
as the EN 50160. All power quality parameters are collected
and analysed e.g. flicker, short term interruptions with
fault recorder function, transients, harmonics up to the
63rd and inrush currents etc. Extensive communication
possibilities e.g. RS 485 Modbus, Profibus, Ethernet (TCP/
IP), BACnet, HTTP, FTP, SMTP, SNTP, DNS ... allow cost
effective and rapid integration in existing communication
networks. Worldwide access to the embedded web
server can be gained through a web browser. The GridVis
software included in the content of delivery allows
extensive analysis just by the click of a button.

Areas of application
Continuous monitoring of the power quality e.g. EN 50160
Ethernet gateway for subordinate measurement points
Analysis of electrical faults for network problems
Monitoring of the internal distribution network according to
EN 61000-4-7, 4-15, 4-30

Power quality analyser UMG 511

UMG 511
Added value with additional functions

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
instruments 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 and analogue 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.

Programming of customer specific applications in Jasic

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.

92

Chapter 02
Power quality analyser UMG 511

Display examples
The backlighted active matrix 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
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 three-phase system.
Alternatively, the current input can be allocated to
the three-phase system of the main measurement for
measuring the neutral-conductor 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).

MRG 604 / 605 / 508 / 511

Mobile power analysers

MRG 604 / 605 / 508 / 511

Again and again we see components and equipment

failing in electrical networks, with the reason behind it
often suspected to be mains feedback effects. Often only
mobile measurement devices can provide information on
this if there are no fixed integrated measurement devices
available in the respective energy distribution system.
This is where the MRG 604/605/508/511 comes into its
own.

The focal point here is the checking of the supplies in

accordance with EN 50160 as well as the distribution in
the internal network according EN 61000-2-4.
Causes of network problems can be identified and
rectified.

99

Chapter 02
Scope of operation MRG 604/605/508/511

MRG 604/605/508/511
Added value through additional functions

Network analysers from the MRG range are intended

for fault analysis and cause identification in low voltage
systems. Thus, with overloaded capacitors in a reactive
power compensation system a long-term harmonics
analysis can provide information on whether the overload
is perhaps caused by too much noise on the grid (THD-U),
for example. However, the recording of load profiles can
also play an important role in the new dimensioning of
system components or for the negotiation of power
supply contracts. Mobile network analysers offer an
advantage in particular with sporadic problems or fault
analysis or in cases where certain measured values must
be even more closely localised.
Along with the large number of electrical measured
values this range offers a multitude of additional
functions such as the saving of minimum and maximum
values, operating hours counter, bi-metallic strip function,
password protection and much more.

Main features
 Continuous monitoring of the voltage quality
Capturing of all significant voltage quality parameters
(harmonics, short-term interruptions, asymmetries etc.)
Ethernet and embedded web server
GridVis software

Applications
The mobile network analysers from the MRG range are
suitable for measuring and saving electrical variables in
low voltage networks. The measurement is designed for
single and 3-phase systems with voltages up to L-N 50500VAC, L-L 80-870VAC with an auxiliary voltage of 85265VAC.
Areas of application
The MRG range is used as a portable measuring device in
distribution systems where there are no fixed integrated
measurement devices available. These are ideally suited
to carrying out mobile measurements, e.g. for the
design of reactive power compensation systems, for
the determination of load profiles or harmonic analyses
of up to 63rd level harmonics. Thanks to the integrated
measured value memory it is not necessary to set up
additional equipment, such as a laptop or printer, with the
measurement device. The evaluation can be carried out
conveniently back at base on the PC.
Capture and recording
All measured values can be stored in arbitrary intervals
in the MRGs internal 128/256 MByte flash memory. The
Software GridVis which is skope of the delivery can then
read out and visualise this data. The recording interval
is also the averaging period of the respective measured

100

EN50160 , IEEE519, ITIC, EN61000-2-4 analyses

Cost centre report
128/256MB internal memory for storing measurement data

value. The maximum and minimum instantaneous values

(200ms averaging period) can also be recorded at the
same time, for saving and evaluating the data as of curves
y(t). Of course it is also possible to save the data in the
form of a histogram, i.e. distribution curves. The recording
of transients and events is initiated through triggers.
Transients are captured from times of 50s or more.
Events such as overcurrent or undervoltage/overvoltage
(>10ms) can also be recorded at the same time.
A network quality report allows a transparent overview
regarding whether the standards EN 50160 or EN 610002-4 are fulfilled over the stipulated time-frame, practically
with one mouse click. A printout is implemented in
paper form or as a PDF file. An Ethernet TCP/IP interface
connection to the PC is available.

Main features and customer benefits MRG 604 / 605 / 508 / 511

MRG 508/511:
User-friendly colour graphical display with intuitive user guidance
The MRG 508/511 devices high resolution graphical display provides
informative presentation of online graphs, FFT with harmonics displayed
in bar diagrams, clear presentation of the monthly kWh values, alarm
management / event display with date and time stamps and many other
functions. Along with the informational content great emphasis was
placed on the user-friendly, self-explanatory and intuitive operation of
the device, when the device display was being re-designed.
Modern communications architecture via Ethernet:
Cost-effective, fast and secure communication
Through connection to an existing Ethernet architecture, fast, costoptimised and reliable communication can be set up.
Large measured data memory, free recording conguration
The large measured data memory of 128 or 256 MB enables the recording
of the measurement data for up to one year, depending on the recording
configuration. The user can freely define which of the 800/2000 different
values have to be recorded and with which averaging period.
Limit value programming via graphical programming
Each measurement parameter can be used to establish limit values. Links
and logical decisions can also be created via the graphical programming
with high flexibility.
Alarm management:
Emails and homepage keep you informed, wherever you are...
Who isnt familiar with this situation? Only barely out of the building
and the first call comes in with problems in production, computers have
failed, the power supply has failed ...
With a web browser and an IP address you have direct access to the
extremely powerful device homepage. You can pick up extensive
information straight away, directly from the homepage. Online data are
available along with historical data and graphs of events and transients.
The accumulated work can be converted to costs directly on the
homepage, and then exported as a csv file or printed out.
Alternatively, have yourself kept informed globally by email - if your
energy supply should be overloaded, short-term interruptions in
the power supply bring your manufacturing process to a standstill,
impermissible harmonics reduce the service life of your equipment...
The application opportunities are boundless.

reading of online values for monitoring the present load.
The software is a powerful tool for voltage quality. It
provides online values or display of waveform of current
and voltage and a quick overview of the actual online
situation, for example.
Automatically generated reports for the most power
quality standards (EN 50/60, IEEE 519, ITIC, EN 61000-2-4)
as well as energy consumption reports can be freely
planned by the user.

PM Power Management

Professional energy management considers aspects such

as peak demand management, energy data collection and
cost centre management. With the UMG 508Emax and
ProData product groups and state-of-the-art pulse output
energy meters, the energy supply for your company can
be actively controlled with regard to power peaks and
energy consumption. The electricity consumption and
electricity costs can, therefore, be sustainably reduced.

The ProData series enables you to have a transparent

invoicing system within the company and monitors the
individual cost centres with separate invoicing. This
improvement to cost transparency enables the respective
allocation to cost centres. This is especially important for
accurate determination of the costs for your products and
services and for transferring electricity costs to your end
consumers.

Electronic energy meter with pulse output

Electronic energy meters are measuring instruments

which are used to determine energy consumption of
electrical loads. The meters can either be used for direct
connection or for current transformer measurements.
Typical areas of application are in the field of energy
management for cost centre analysis, as a measurement

value generator for PLC controls or in central building

control systems. Electronic meters should be calibrated
and sealed for invoicing purposes in order to guarantee
continuous accuracy and to protect the meter from
misuse or unintended reprogramming.

Chapter 03
Series ECS

The ECS series energy meter

Areas of application
Electronic energy meters are mainly used for collecting
data of effective and reactive energy consumption. Their
standard area of application is in the field of energy
management for cost centre analysis. There are various
communication possibilities available in order to avoid
time-consuming manual readings at site. The effective
pulses can be connected via two impulse outputs e.g.
DDC, PLC, SCADA systems or the data logger ProData. In
the area of central building control systems the protocols
M-Bus, EIB-KNX and Modbus RTU are available through
additional communication modules which read the actual
meters using an optical interface and which provide the
respective value on the field bus through the interface.
The selection of additional values such as voltage,
current, power, power factor and frequency together
with effective and reactive energy are available on the
bus cable through the communication modules. For
consumption data collection, the ECS meters can also be
used as instruments for sub-metering for the UMG 604
through Modbus RTU.

Main features
Communication modules: Modbus, M-Bus, EIB-KNX
Direct measurement up to 125A or through current transformer
2 tariffs
With and without MID calibration
Sealed clamp covers
Four quadrants measurement
Measurement values: effective energy,
reactive energy, effective power, reactive power
Class 1

Applications
The electronic energy meters of the ECS series are
suitable for the measurement of effective- and reactiveenergy consumption. Measurement is laid out for a 1- and
3-phase system with a voltage of L-N 184-276VAC. The
current inputs are designed for direct connection or for
measurement through current transformers. Installation is
undertaken on DIN-rails, whereby the extremely compact
construction is of particular value. There are two versions
available: a non-calibrated version and a calibrated
version (MID). All meters in the ECS series can be sealed.
The effective and reactive energy is available in two tariffs
and in four quadrants. The accuracy of the meters is class
1 for effective energy and class 2 for reactive energy.
Data collection and recording
All meters store the counter values in non-volatile
memories. The meter reading cannot be reset in the
calibrated version. In the non-calibrated version the
readings can be reset. The current transformer ratio is
fixed (5:5) for calibrated meters.

UMG 508Emax

UMG 508Emax peak demand management systems

Energy consumption varies significantly over a 24 hour

cycle period. This leads to massive strains on production
and distribution systems and also causes expensive
peak load coverage e.g. pumped storage power plants.
In order to balance out these effective power peaks,
the energy suppliers have introduced corresponding
demand price tariffs. According to the tariffs offered by
power companies, the highest measured power peak
value within a period of 15 minutes is used to establish
the monthly electricity costs. Using this peak value, the
network allocation costs and the monthly energy price are
then calculated. If this peak value is reduced the electricity
costs will also be reduced. In times of constant increases in
the costs of electrical energy, it is imperative that optimum
adjustment of the load distribution profile is ensured on
the peak load optimisation systems. The solution to this is
an Emax application for Jasic devices such as the UMG
604, UMG 605, UMG 508 or UMG 511. Depending on the

trend value, the installed Emax application switches off

the consumer temporarily, which allows the switching
times to be configured freely. Unnecessary switching
actions are avoided if consumer feedback is connected.
Areas of application
Reduction of effective power peaks and, therefore,
significant reduction of electricity costs
Avoidance of short-term overloads in energy distribution
systems (e.g. triggers power switches)
Stabilisation of energy supply and production processes
Hotels, canteen kitchens, hospitals, industry, compressors,
thermal processes

UMG 508Emax - peak demand management systems

The intelligent reduction of effective power peaks

Emax applications for Jasic devices continuously

capture all electrical parameters. Integrated smart
control algorithms calculate the effective power trend
and compare it with the fixed target effective power. The
trend calculation allows the Emax application for Jasic
devices to intervene in the operational process precisely
and to switch off non-critical consumers temporarily.

Main features of the Emax APP

Optional limitation of effective peak loads
Up to 64 switch-off stages with feedback,

If feedback processing is connected, only those consumers

which draw power at the time of the calculation are
switched off or included in the trend value calculation. If
feedback processing is not possible, fixed availability may
be set in percentages, which to some extent helps to avoid
cost-intensive peak loads and achieves considerable cost
saving potential. Incidental peak loads are avoided.

UMG 508Emax

Applications
The UMG 508 is a multifunctional device which plays
a role as basic equipment in all low-voltage mains
distributors. The optional Emax application reduces the
effective power maximum by temporarily switching off
consumers.
As a basic unit, the UMG 508 is assembled with additional
components in stainless steel casing or available as
individual components. As a measurement device, the
UMG 508 records the load conditions of electrical power
supply equipment so as to prevent the occurrence of
overloads. Furthermore, the device is also designed to
measure and save virtually all electrical values including
ow and power values. Visualisation of the measured
values recorded by the maximum monitor is displayed on
the device homepage. Display of the measured quantities
on the display is not possible.

Functional principle
On the basis of the effective power pulse emitted at a
digital input or the total effective power calculated by
the measurement device (direct measurement), the
Power Analyser Emax programme records the necessary
quantities in order to observe a pre-set nominal value. In
doing so, the system constantly calculates the average
value, instantaneous value, trend value and corrective
power within the pre-set measurement period.
Should the Power Analyser detect that the maximum may
have been exceeded, it determines the need for a switch-

Illustration: Emax status display

off with the help of the set loads. Loads are then switchedoff with due consideration for the pre-defined rules. The
aim of this method is to adhere to the set maximum at
the end of the measurement period with as few switchoffs as possible, and therefore as little negative impact
to the operational process as possible. A feedback input
(release) may be assigned to each load of the Emax
function. These inputs allow the availability of the load for
maximum monitoring to be restricted. In order for it to
be possible to switch the load off, one or more expansion
modules with digital outputs are required (FMB 10 R-NC).
Should the status of loads be taken into account via a
feedback input, an appropriate input module (FBM10I)
must be connected to the serial interface.

should also install the profibus add-on APP to App Emax.
The add-on installs an additional profile. Nominal value
switching and feedback processing are also possible via
the profibus. Measurement period reset is not possible
via either the modbus or profibus. Measurement period
reset is only possible via a digital input.

ProData

ProData data logger

Data collection and recording

ProData data loggers are used for the collection of any

physical measurement data (temperature, pressure, ...)
or any consumption values (electricity, water, gas,
coolant...). ProData data loggers consist of a programmable microprocessor, storage media, several
interfaces and 16 channels for connecting sensors or
pulse generators. External sensors are used to collect
the measurement data and convert it with analoguedigital converters into memory-safe data in order
to be able to be stored by the ProData storage media.
The collected data is read out through an interface and
is analysed with suitable software. The ProData can also

be configured for the application through one of these

interfaces (e.g. measurement intervals etc). Data loggers
are indispensable for energy management systems e.g.
for cost centre management. ProData data loggers are
also indispensable in the field of status monitoring.

Areas of application
Data collection and recording of meter values
Electricity cost data collection and cost centre
management
Analysis of process data
Condition monitoring

Chapter 04
Power factor controller Prophi

PFC system lifespan Prophi

Optimised control for long

The Prophi power factor controller has an optimised

control mode. The implemented control algorithms
reduces the number of switching cycles as well as the
operating time per capacitor stage.
The aim is to have the same number of switching cycles
and, if possible, the same operating time per capacitor
stage. In addition, the number of switching cycles is
reduced by up to 80%.

The lifespan of the entire system can be significantly

increased through even loading of all stages with an
automatically regulated PFC system. This means that
invested capital earns money for a longer time period and
that new investments can be avoided.
The hybrid switching (i.e. the combination of capacitor
contactors and dynamic thyristor modules for contact-free
rapid switching of capacitors) combines the advantages
of rapid switching without network perturbation with the
cost advantages of common PFC systems.

129

Chapter 04
Power factor controller Prophi

Power factor controller Prophi

Applications
PFC systems are used to discharge unnecessarily
overloaded supply systems through inductive reactive
power and to save reactive consumption costs. The
reactive power controller is the main part of a PFC
system and automatically switches capacitors steps on
or off. The Prophi power factor controller is suitable for
use in conventional and dynamic PFC systems. A mixed
operation (hybrid switching) is possible as well.

Functional principle
The single-phase electronic measuring system collects
the reactive and effective current ratios of the network
through the current and voltage measurement. Using the
current from one phase and the voltage from the other
two phases, the reactive power controller calculates
the necessary reactive power to achieve the set target
power factor. The capacitor steps are switched on or off

130

if any differences occur and the reactive power controller

differentiates between the switching of capacitors through
contactors or thyristors. The control through capacitor
contactors is optimised; this means that the reactive
power factor controller achieves the cos-phi target with
a minimum of switching actions. The transistor outputs
control the semiconductor switches for almost immediate
compensation of any differences.

Chapter 04
Power factor controller Prophi

Ventilator control
Simple ventilator controls can be developed with the
temperature sensor which is built into the Prophi and a
ventilator. A relay output or the alarm relay is used for
controlling the ventilators. The upper/lower temperature
limit can be programmed for this feature.

Excess temperature shutdown

Connected capacitor steps can be disconnected with the
excess temperature shutdown function in order to reduce
the temperature inside the PFC-system cabinet and to
protect the capacitors. The upper/lower limit temperature
and pause time can be set by the user.

Automatic conguration
The LEARN function offers the opportunity to learn the
connection configuration of the power factor controller
and save it.
LCD display
The Prophi power factor controller has a high-quality
LCD display with high contrast. Extensive measurement
parameters (approx. 100 measurement values) can be
displayed via LCD.

Display examples: voltage

Interface
The Prophi power factor controller is equipped with a

Software

Software solutions especially adapted to suit you

In the field of energy management, the processing

and analysis of energy data and measurement data for
electrical power quality is the main focus. All important
measurement data should be able to be documented
without any interruptions in order to be able to find
reasons for production breakdowns, manufacturing
problems or quality defects.
For example, the
chronological arrangement of voltage fluctuations,
harmonics or network failures can prove whether these
are the causes of the occurring problems. If insufficient
power quality is identified within time, increased wear
and tear or the ruin of electrical supply systems and
equipment can be avoided and the danger of fire can be
significantly reduced. Load profiles and consumption can
be analysed to introduce measures for the improvement
of energy efficiency.

The GridVis software systems of Janitza electronics

GmbH, is suitable for programming and configuring
power quality analysers, power analysers, universal
measurement instruments, data loggers and reactive
power controllers as well as for the administration and
visualisation of all measured data. The electrical data from
companies can be monitored at a glance in the topology
overviews. The measured values are written in the data
memories of the units or directly online in databases
and can then be presented as line graphs, bar charts or
histograms.
Power quality reports can be created from the database

Grid visualisation for more transparency in the network

The GridVis Basic software is part of the standard package

supplied with the power quality analysers, power
analysers, universal measuring devices, data logger and
power factor controller.
This software can be used to present the measurement
values as actual values online and a graphic presentation
of the values read from the measurement value memory
is also possible.

The topology overview guarantees a quick overview of

the complete electrical network. The GridVis software
also serves the purpose of parameterisation of the
measurement instruments. Furthermore, the creation of
customer-specific programs is possible using our own
developed programming language, Jasic, or the userfriendly graphic programming periphery.

GridVis
Software for grid visualisation

The GridVis software for programming and grid

visualisation, which is part of the standard delivery
package of all power meters, enables a simple and
complete para
meterisation of the power analysers.
Customer specific visualisation of the energy supply
is possible with the topology view. The individual
measurement instrument can also be operated online
using the mouse, if the corresponding device supports
this feature. Measurement data can be directly recorded
on the PC in online graphs. Furthermore, GridVis offers
convenient opportunities for presentation and analysis of
historical data from the database.
The automatic ring buffer download and integrated data
management has a particular positive effect in medium
and large sized projects as data can be stored in various
database formats. With the graphical programming, user
specific programs can be created for the measurement
instrument families UMG 604, UMG 605, UMG 508 and
UMG 511.

Main features

Visualisation of energy supplies
with the help of a topology view
Documentation of power quality
for freely definable periods of time
Analysis of the root causes of faults
Cost centre management i.e. simple
and precise electricity cost calculation
Stabilisation of energy supply through the
alarm function when limit values are exceeded
e.g. overvoltage or short-term interruption
Improvement of power quality e.g.
harmonic analysis for fault detection
Load profile analysis e.g. consumption
prognosis for electricity contract negotiations
Online storage of up to 10 devices without memory
Programming and configuration
Using the software GridVis all power analysers are
completely configurable. Any name can be given to the
instruments and connection mode and PTs and CTs ratio
values can be set. Trigger values for the measurement of
events and transients, as well as the measurement values
which are to be stored and their recording intervals are
determined. Limit values for the monitoring function of
the digital outputs are programmed using the comparator
or the pulse value for the digital inputs or outputs is
established.

Illustration: Pre-configured recording profiles

The external temperature sensor can be selected. The

time server for time synchronisation is also determined.
If it is necessary to carry out an update on the measuring
instruments, this can conveniently be done by the
software without the instrument having to be dismantled
or returned to Janitza.
The most recent updates for software and instrument
firmware are available free of charge at www.janitza.de.

Online data
The software GridVis allows an individual collection,
reading out and visualisation of online data. The received
data of multiple measuring points are collected, saved,
processed, visualised and provided for further use. All
measured values are available in the mode of online
measurement either as a line graph or bar graph. The line
graphs are permanently actualised and the most obsolete
data are cancelled. Two scales can be created for two
different units per graph. Any number of measurement
data from each unit, including from several measurement
instruments, can be observed in the same graph. In
the graphs, the indication of transients and events is
displayed. The colour of the graphs can be adjusted as
required.

Illustration: GridVis indication of various online data

Virtual device: combine measured values

The creation of a virtual device allows measured values
to be combined within the GridVis. Therefore, it is
possible to make different data sources from a range of
measurement devices available to the virtual device as an
input.
Mathematical connection of input sources can be realised
using operators, and various and freely-definable outputs
can be assigned.
The virtual device appears as a real measurement device
within the GridVis. The capture, readout and visualisation
of online and historical data is carried out analogous to
the actual measurement devices.

Topology View (Graphical User Interface)

A device view of any instrument in the network can be
called up. Beside watching the actual display, you may
also remotely control the complete instrument as if
you were on site. All measured data can be displayed
simultaneously. The topology gives a quick overview
of the energy distributions and the possibility to locate
power failures by comparing measuring points and
checking the defined tolerances at a glance.
Depositing some graphical files (common formats such
as.jpg) with circuit diagrams, flow processes or building
plans and binding of the corresponding instruments by
drag and drop to their real position, you can establish
customer specific solutions quickly and simply. Limit
violations e.g. high THD-V as well as conditions of inputs
or outputs can be indicated as well.

Event and transient browser

With the two functions EVENT- and TRANSIENT-browser,
freely definable time periods can be checked regarding
occurred events and transients. These functions (e.g.
illustration: transient browser) are especially essential for
failure analysis.

Illustration: Transients

Data memory
Most measuring instruments have a memory. Reading
out the memory, the data are saved within a database. e.g.
Derby, SQL and MySQL are available. The most preferable
databases are MySQL or Microsoft SQL server databases,
as they are much faster than the derby database, which is
of importance especially in large projects. MySQL can be
downloaded free of charge at www.MySQL.org.

Software GridVis
Offline data
Data stored in the GridVis database can be displayed as
line graphs, bar graphs or histograms. Also parameters
such as year, month and day are stored. Therefore, the
data can be easily selected. Particularly interesting periods
of time can be enlarged with the zoom feature. The graphs
can be provided with titles and comments and be printed
out. The display of transients and events also takes place
here within the transient and event browser. The flag

browser can be used to examine whether measurement

data are missing at certain periods of time or whether the
data are not reliable. With the analysis of historical data
you can build load profiles for exact demand analysis to
opain optimised supply contracts. Also failure analysis
by comparing various parameters can be carried out by
a few mouse clicks.

Important parameters of the electrical energy supply must

be measured and monitored within the context of energy
analysis. The data sets provided by the measurement
devices are displayed in the GridVis online as an
instantaneous value or from historical values. Analysis
of these data is possible using the report and statistics
generators in the GridVis, where the most important
parameters are presented in tabular or graphic form.
Individual reports are generated automatically using
freely-definable schedules or manually generated by the
user. Reports can be produced in paper format or as an
HTML, XML, Excel, Word or PDF file.

Programming language Jasic and Licences

Unlimited Programming Options

The programming language Jasic opens up completely
new possibilities. You are no longer limited to the devices
built-in functions, but the device can be extended with
your own functions and applications. The graphical
programming is used to create and configure logical
operations or mathematical functions. You can activate
your own digital outputs depending on pre-defined
thresholds for example and digital inputs are evaluated.
In addition, it is possible to analyze or write registers
of external Modbus devices (license). With the tool
graphical programming it is possible to customize your
own applications according specific requirements and
extend by far the functionality of the measurement devices
of the UMG device series UMG 604, UMG 605, UMG 508
and UMG 511. Even limit violations, timer functions or
recordings of special values are user configurable with
the graphical programming. The self-made programs can
be stored on the computer as a file, or directly transmitted
to the UMG measurement device. For the storage of your
customized programs there are 7 memory locations, each
with 128 kByte memory space available. The graphical

APPs Expansion with know-how

For flexible or client-specific solutions, Janitza electronics

offers software-based expansion options (APPs) for a
range of measurement devices. The functions that are
integrated into the device can therefore be expanded,
controlled and visualised using APPs.

The programming language for the development of

APPs is Jasic.
Jasic uses syntax similar to that of BASIC.
Alternatively, programming may also be undertaken
graphically using the GridVis.
Depending on application programming knowledge,

Depending on the application, an APP comprises multiple

Jasic, flash and homepage files. Management and
installation is carried out using the GridVis software. In
addition to the APP range provided by Janitza electronics ,
the open structure allows users and third-party vendors
to develop APPs and to use them with measurement
devices.

APP development may be undertaken in Jasic,

JAVA Script, JSON, AJAX or Action Script.

APP Emax (item no 51.00.213-215)

APP Multitouch (item no 51.00.207)

The APP reads out 25 measured values (pre-set defaults)
from up to 31 slave devices (configurable) via RS485
and registers them in the master to global variables* or
BACnet datapoints.
The measured values are displayed on the JPC35 touch
panel or the device homepage (browser with flash plug-in
required). It is not possible to save the measured values
in the master devices; the expansion is a simple live value
display.
The APP contains an integrated BACnet gateway function
(optional, item no 52.16.083), where the measured value
from the global variables is added to BACnet datapoints.
The BACnet can be modified via the homepage. Note that
the COV in this application is not supported.
The programme installs a control programme which calls
a corresponding subroutine, depending on the master
device (UMG 604, UMG 605, UMG 508, UMG 511) (slave
device: UMG 96S, UMG 103, UMG 104, UMG 604, UMG
605 and UMG 96RM).
The choice of substation is made via a user-friendly general
overview which displays all possible communication
errors (RS485 bus) via a status display.
Up to 31 slave devices can be visualised. The number of
devices and device descriptions can be configured via
the master device homepage. The master is recognised
automatically and registered in the device type field.
BACnet configuration is also performed via the master
device homepage, where a unique BACnet ID can be

OPC server
the big, wide world of automation

Once a while it is required to incorporate measurement

values from power analysers into non-Janitza visualisation
systems but the existing visualisation system does not
support the protocol which is contained in the measuring
instrument. OPC servers act as an interface between the
measuring instrument and the central building control
system or PLC in these cases.

The OPC can be used to link the measurement data with

the data from other trades and archive it in the database
structures for process control techniques. OPC drivers
for process control techniques are used by almost all
renowned manufacturers of building automation systems.

OPC drivers, therefore, offer a standardised interface for

easy data exchange without exact knowledge about the
communication options in the counterpart system.

OPC server

Modbus Suite TOP Server

Janitza electronics GmbH has been recommending the
proven and cost-effective OPC Top server with Modbus
suite from Software Toolbox (www.softwaretoolbox.com)
for years. Support is also provided in connection with
UMG measuring instruments and power analysers.

Functions of the OPC server

The OPC server is a software driver and must be installed
on a PC in the network. If the existing automation software
is already running on a computer with sufficient power
reserves and if the operating system is compatible with
the OPC server, installation will be possible on this
computer. If sufficient power reserves are available, the
OPC server also will runs on systems in which GridVis is
already installed.
The software driver contains a Modbus TCP/IP or a
Modbus over TCP/IP Master and an OPC server. The data
(e.g. measurement values) is read out using the Ethernet
interface (port 502 or port 8000) and is passed on to the
OPC server. The OPC server then passes on the data to
the OPC client of the external program. Access can be
simultaneously gained to up to 6 software applications on
port 502 of the UMG 507E/EP and UMG 604E/EP. Another
two applications can be simultaneously accessed on down
stream measuring instruments using the RS485 (Ethernet
encapsulation). This means that measurement data can be
simultaneously read with GridVis and the OPC server.

Illustration: Determining OPC variables

Configuration of the OPC server

The OPC server is configured using a convenient operating
area but does require some basic knowledge of the data
types (Word, float etc) and bus technology. Communication
settings can be individually adapted for each channel.
Following data types are supported:

Char, Byte, Long, Float, Word and Double as Big-Endian

and Ldittle-Endian. The OPC server also contains an OPC
Quick Client for quick online control of the data.This means
that the data is automatically taken from the configuration
table and displayed. The statistics function assists fault
detection.

The meaning of OPC

OPC is an abbreviation for OLE for process control
and is a standardised interface in the field of automation
technology. This term is frequently used in the field
of building automation. OPC was created to provide
industrial bus systems and protocols with a universal
communication possibility. An OPC driver can be
integrated into any size control and monitoring system
without any major adaptation efforts.

Current transformers

Current transformers
The link between power currents and digital technology

Obviously currents of several hundreds to thousands of

Ampere cannot be directly digitally measured. Current
transformers convert almost any amount of primary
current into bite-sized secondary currents. The
secondary output is .../1 or .../5A.
Janitza electronics GmbH has a wide range of various
current transformers whether these are moulded case
type current transformer, summation current transformer
or cable split core type transformer.

Areas of application
Conversion of high primary currents into standardized
secondary currents .../1A or .../5A
Transformer classes 0.5 or 1 depending on the
instrument
Transformers are available for various bus bars and
cables
Moulded case type transformers for cable or bus bars
Cable split core type transformers for cables when the
electricity path cannot be opened
Summation current transformers

It is recommended to select the accuracy classification

of the current transformer to match the accuracy
classification of the connected measuring instruments.

Moulded case current transformers

Moulded case current transformers

Applications
Current transformers are used when currents cannot be
directly measured.They are a special form of transformers
which transform the primary current into a (mostly)
smaller secondary current and galvanically separate the
primary and secondary circuits from each other. Due to
the physically determined saturation aspect of the core
material, additional protection against high currents in
the secondary circuit is achieved.

Applications
Summation current transformers have the task of adding
up the secondary currents from various main, CTs and,
therefore, making the measurement of an instrument
accessible. Summation current transformers redeliver a
norm signal at the output. This means that not only an

addition of the input currents takes place but also the sum
is divided through the amount of summands (number
of inputs). We differentiate between summation current
transformers for even and uneven main transformers.

DIN-rail current transformer

DIN-rail current transformer

DIN-rail current transformer

CT 35/1A and 64/1A with voltage tap
While measuring in substations, there are often problems
regarding the space, as voltage and current are necessary
for each phase. Those problems can be solved by using
the DIN-rail CTs, which combine three functions in one
device. The DIN-rail CT consists of series terminal, current
transformer and voltage tap with fuse. The fuse is directly
mounted on the primary and therefore the non protected
part of the measuring cable is very short, which ensures a
high intrinsic safety.

The DIN-rail CTs lead to simple wiring, low mounting costs

and high reliability due to less connections, retrenchment
of space and rare connection errors.

Current transformer

DINCT64/1/1 DIN rail current transformers

Deeper measurements (sub-distributions or loads/

individual output) are more and more common in
electrical installations.The nominal currents are, therefore,
relatively low (64, 32 or 16A), the space is restricted and
the accuracy of the current transformer must be sufficient
for the power measurement (minimum class 1). These
characteristics are often difficult to combine.

Some instruments with Profibus connections require a

Profibus connector. The incoming bus cable is connected
to the 1A/1B terminal and the continuing bus conductor
is connected to the 2A/2B terminal. The slide switch is
used to activate the terminal resistance at the beginning
and end of the bus system. The terminal clamps (2A/2B)
are simultaneously switched off for the continuing bus
conductor.

Note:
For the UMG 507, UMG 508, UMG 511 the
connector is also used for the Modbus.

IT and field bus components

In addition to simple data collection with power analysers,

industrial data communication, i.e. the transfer, central
storage and processing of the data, also plays an important
role in energy management. Janitza electronics offers
frequently used and proven IT and field bus components
supported by Janitza. Interface converters are included
together with IO modules, repeaters, industrial Ethernet
switches, ISDN modems, signal converters and a mini
UPS for problem-free operation of your system.

De-centralized field bus IO/modules series FBM10

All FBM10 modules have an interface RS485 with Modbus
RTU protocol and can be used as slaves to the devices of
the UMG 604, UMG 605, UMG 508 and UMG 511 series.
The UMG 104 and UMG 507 series cannot be used as a
master for the FBM10 modules.

Use of the module FBM10PT1000

The PT1000 temperature field bus module is used for
capturing up to 10 temperature measurements (e.g. with
PT100 or PT1000). The measured values are plotted and
visualised using a UMG 604, UMG 605, UMG 508 or UMG
511 and a necessary expansion (in accordance with the
section APPs).

All FBM10 modules are configured and programmed accordingly

by Janitza electronics for each device.

Distance
The I/O modules of the FBM-series can be connected up to
1000m distance to the RS485 Modbus master. Cable type
should be used either a Profibus cable or type Li2YCY (TP
cable) 2x2x0.22.

Application of I/O field buses

The field bus module has no own intelligence, but it
takes up the various input and output signals in order to
distribute to the participant. To use the field bus modules,
a connection to each Modbus master device such as the
UMG 604, UMG 605, UMG 508 or UMG 511 is necessary.
With the inclusion of the remote I/O modules are two
different versions available. The user can basically
integrate all data points in his Janitza system. In this
case the Janitza system is no longer limited only on
electrical parameters. In principle, other values such as
process data, status, alarms, limits, alarm outputs or the
like can be recorded. This values can be captured with the
software GridVis for live and historical data.

Decentralised WAGO I/O system
for client-specific programming (APPs)

Application
Client-specific programming is achieved with the help
of the WAGO I/O system. The decentralised field bus
coupling is controlled via RS485 Modbus RTU. Communication takes place between the UMG instruments and
one or more bus couplers to which the corresponding
inputs and outputs are detachably interconnected.
The WAGO I/O system is attached to a DIN rail. As a bus
cable, a profibus cable or other suitable cable, such as
Li2YCY(TP) 2x2x0.22 should be used, where the maximum
distance between the master and slave may extend to
1000m.

Illustration: WAGO coupler with RS485 connection (15.06.202)

with outputs (15.06.250) and end terminal (15.06.251).

Suitable for devices: UMG 604/UMG 605/UMG 508/

UMG 511
The APPs are programmed on an application by application basis depending on client requirements. For tendering purposes, an appropriate application description is
required (specifications). A separate homepage is created
for each application for displaying the measured values.
Possible applications: Compressed air capture via analogue
inputs, analogue output of calculated or measured
values, display of physical measured quantities etc.

PowerToStore 10F mini UPS for UMG 604E

Capturing short-term interruptions is one of the

strengths of the UMG 604/605/508/511. Due to the small
construction and the large memory, the instrument is
ideally suitable for monitoring transformer stations. The
UMG 604s auxiliary voltage supply is provided through
a switch mode power supply which has been developed
for both DC and AC operation. Voltage interruptions
of approximately 80ms are safely bridged. Voltage
interruptions which are longer than 80 ms cause the UMG
640E to shut down. In order to capture longer short-term
interruptions, the auxiliary voltage supply of the UMG 604

must be backed up with a UPS. If a UPS is not available,

the PowerToStore will be used. Usually batteries are used
in UPS units. However, the disadvantage of batteries is
the regular maintenance. The PowerToStore 10F is an
energy buffer based on capacitors. Therefore it does not
require batteries and is maintenance free. The capacity
level has been designed so that 3 x UMG 604E can be
supplied with energy for approximately 3.5 minutes. The
maximum number of UMG 604s which can be connected
is limited to 3 instruments.

Server

Database server

Extensive power quality monitoring and energy

management applications require high-performance
server solutions. Janitza electronics can support you
with the selection of a suitable system. Furthermore, we
can offer you a high-performance server as a complete
solution. Janitza electronics guarantees problem-free
and immediate use.
Your system administrator only needs to integrate the
server which we configure into your own network. We

supply a fully installed database server with GridVis

software. You can choose between an MSSQL or MySQL
database.
Janitza electronics uses high-performance towers or rack
servers from Dell. Dell Power Edge-Servers offer a high
quality and reliability with maximum extension options.
A high level of data security is offered by the use of RAID
5 systems with HotPlug hard drives.

185

Chapter 06
Server

We leave you also after the purchase not in the lurch...

With Janitza electronics maintenance remote diagnosis,

the service technician can remotely access your database
server (only with your permission!) and can, therefore,
diagnose and correct the problem within a few minutes.
We use common remote maintenance solutions with
triple level coding according to industry standards.

We currently recommend the following server

configuration for larger projects:
current Intel processor
16 GB RAM
RAID controller
RAID 10 with 4 hard disks (each 1 TB capacity)
DVD Rom drive
incl. mouse and keyboard
Windows 2008 Server with 5 CALs, 64 Bit
(german or english version)
incl. installation of software GridVis
incl. database installation Janitza-DB, MySQL or MS-SQL
Quotes are available upon request

Areas of application
Recommended for larger projects with a high number of
measuring instruments and everywhere where high data
security and maximum performance is required. Systems
can be individually configured for small and large sized
companies.
Application
The GridVis software works with an additional programme
as a service on the server. The user does not have to be
logged on. For measurement value analysis, the client
computers access the server directly through the network.

Application
Any number of client systems can access the measurement
data within the database. The presentation of online
measurement values is dependent upon the number of
ports per unit i.e. the client computers directly access the
UMG instruments for online values and for historical data
from the database. The following graphic illustrates this:

Historic data

The UMG 507E, for example, currently has 6 communication ports. Two of these ports are designed as a gateway (port 8000) for
downstream RS485 units.

The ports can be allocated as follows:

Port 1 = database server for downloading the UMG memory by automatic download
Port 2 = client computer 1 accesses the online values from UMG 507E and UMG 96S
Port 3 = client computer 2 accesses the online values from UMG 507E and UMG 96S
Port 4 = client computer 3 accesses the online values from UMG 507E
Port 5 = BMS (Building management software) accesses the online values from UMG 507E
Port 6 = OPC server accesses the online values from UMG 507E

Touch panels

Touch panels

For user-friendly visualisation of measurement parameters without PC directly at site, touch panels are a
perfect solution. The simple installation, which is almost
enabled with plug & play, guarantees the rapid display of
measurement values in the switch board door.
Numerous measuring instruments can be compiled on to
one display. Just one cut-out is now sufficient instead of

several switchboard door cut-outs which were formerly

required. This saves space and costs and ensures that a
better overview is achieved. Standard applications can
be supplied for all touch panels. The touch panel JPC150,
based on a web browser, can provide customer-specific
solutions upon request with a display of a circuit plan or
the display of service telephone numbers etc.

General
In order to monitor electrical data at site, so-called
embedded systems provide solutions in the form of touch
panels. Due to the fact that only slight tolerances are
permitted for production machines and processes and that
stand stills outside of certain maintenance intervals are
not tolerated, there are obviously increased requirements
for visualisation by these embedded systems. Classic PCs
do not generally meet these requirements because hard
drives and ventilators cannot be used in a harsh industrial
environment. This is where compact-ash memory cards
can be used due to the integration of special processors
and coolers which do not include any ventilators. Dust,
dirt and moisture are no problem thanks to the high front
side protection class.

UMG 604E

Areas of application
In the field of energy measurement technology and energy
management, touch panels are used for the visualisation
of process and energy data at site. The communication
takes place through two existing Ethernet interfaces in
the JPC150 models. The JPC35 has a RS485 or RS232
interface. The standard application for the visualisation of
up to 32 measuring points* is available for both panels.
Application JPC150
The 15 touch panel features a pre-installed Windows
Embedded operating system. This panel allows
visualisation of websites or different Apps (expansions)
such as MultiTouch via a web browser (e.g. Firefox
or Internet Explorer). All Power Analysers from Janitza
electronics with an ethernet interface feature a webserver
and can be used for graphic or tabular visualisation of
standard measured values. Client-specific websites can
also be transferred to the devices. Janitza electronics
GmbH can also develop special applications on request.
JPC35 MultiTouch
The JPC35 MultiTouch has a 3.5 touch panel and can
be modified and configured for a range of uses. The panel
allows the measured values from up to 32 measurement
devices* to be displayed. The configuration and menu
navigation has been constructed to be intuitive and userfriendly. Each measurement point can be given a specific
name which allows for transparent organisation of the
measured values. The display mode is variable and can
be configured from the display itself.
* 31 slave device and one master device

188

The following modes may be used:

Standard:

Displays the standard measured values of a

measurement device (UMG 604/UMG 605).

Station selection: Displays the standard measured values

from up to 32 measurement points
(31 measurement devices seriallyconnected to the RS485).
Energy table:

Displays the energy consumption of the

individual measurement points in tabular
form.

Chapter 06
Touch panels

A UMG 604 or UMG 605 may be used for the connection.

The RS232 interface is required for communication
between the master and JPC35. The serial RS485
allows connection of up to 31 slave devices. Modbus
RTU communication (RS485) is monitored and in the
event of an error, a message appears on the display.

The JPC35 MultiTouch requires the App (expansion)

(free of charge) MultiTouch (item no 15.00.207) on the
measurement device.
Info: The address allocation of the measurement points is fixed and
cannot be modified! (Address 1 to 31)

Appendix

Application at an energy supply company in

Eastern Europe
In this project, an energy supply company wanted to link
the measurements from its 110kV transformer station and
35kV substation with each other. The transformer stations
are linked with the central control centre of the energy
supply company by using bre optics. Communication
is achieved with Ethernet - TCP/IP. Across various voltage

levels depending upon the information required from the

measuring point and the communication requirements
various power analysers and measuring instruments
where used. The aim was to read out the fundamental
electrical values from all stations automatically together
with power quality measurement values and collect, store
and analyse them centrally.

The problem
Transparency regarding energy costs and power quality
is continuously becoming more and more important in
industrial companies. Energy consumption must be allocated to the production stages and the nal products in
order to simplify pricing policies.
Due to the use of non linear consumers such as frequency
converters, problems often arise with electronic equipment and controls. Reactive power compensation systems are usually subject to particularly high loads and,
therefore, require skilled engineering.
Expensive peak loads can be avoided with intelligent
peak demand management.

The task
A supplier to the automobile industry decided to relocate
its complete production facilities and construct the buildings in a green belt area. The company wanted to collect consumption data for all welding robots together with
compressed air consumption and heating supplies and
provide the data to the controlling department.
The power quality from the four main feeds needed to be
monitored and the four respective PFC systems needed to
be integrated in the energy management system.
Peak demand management had to be anticipated in order to reduce high electricity costs due to high loadpeaks,
shutdowns of compressors and air conditioning units etc.
for a short period will be the solution. Intranet was available as a communication medium.

The solution
The UMG 96 of Janitza electronics, which passes on the
effective pulses to the ProData data logger, was used as
a meter for electrical energy consumption. Other pulse
meters for compressed air and heating were also connected to the ProData using the pulse outputs.
Four UMG 508s were deployed in the four main feeders in
order to determine the power quality. Four Prophi 12TS
reactive power controllers were also visualised using the
RS485 in GridVis software. Distinctive feature:

the conventional contactors. The rapidly changing load

proportions, as caused by welding systems, are switched
using thyristor modules.
This means that dynamic PFC can be created for almost
the same price as the conventional compensation system. A globally unique feature of the Prophi controller.
The UMG 511 works as peak demand management and
as a master for downstream WAGO modules as well as a
gateway for the RS485 bus cable to Ethernet/TCP/IP.

The four PFC systems work as a so-called mixed operation, which means that the base load is compensated using

The problem
In banks, insurance companies and other commercial
buildings, increasing power problems with reference
to harmonics, ickers, voltage peaks and similar effects
have occurred in the past years. Network perturbations
are often transported into the building from the medium
voltage network.
The reason for internal power problems is the large
number of PCs and switched mode power supply units
which are used. Due to the widely branched 5-conductor
networks, so-called stray currents can occur in ground
wires. These are caused by incorrect grounding. These
particularly lead to problems in data networks because
they proceed in cables.
Flickering can lead to discomfort, headaches and tiredness among the members of staff. These disturbances are
certainly not welcome because working in these types of
buildings is made more difcult and may even become
impossible without safe communication options. European norms have existed for several years for the assessment of network perturbations.
EN50160 regulates the power quality which must be provided by the energy supplier. The EN61000-2-4 provides
the opportunity to measure the power quality within a
building.

The task
The power quality must be checked in a large bank at the
feeders in accordance with EN50160 and at the sub-distributions in accordance with EN61000-2-4. Furthermore,
the reasons for frequent problems in the data cables had
also to be identied. The employees in building services
should have access to the data at all times. Intranet was
provided as the communication medium.
The solution
A total of 39 x UMG 511 were installed in the feeders and
all important distributions for communication, such as in
the server rooms etc. An important feature is the fourth
current and voltage input on the instrument. Due to the
installation of the fourth current transformer in the pro-

tective earth conductor, stray currents could be tracked

down. Potential differences due to incorrect grounding
were identied using a separate measurement with the
bridge between N and PE.
The existing grounding errors could, therefore, be corrected. Obviously all of the data with reference to the power
quality and all current related data were stored in the
256 MB memory of the UMG 511. The GridVis software
could be used to read the data at any time. An Ethernet
TCP/IP interface was available for this purpose.
The reasons for the frequent loss of communication in the
data network were found and important knowledge about
the power quality was gained. The producers of harmonics could, therefore, be tracked down. Materials such as
electronic controls or server supply units, which were previously destroyed due to network perturbations, could be
protected with suitable power lters.
Furthermore, the monitoring of the power quality from
the energy supplier was made possible in accordance
with EN50160. A pleasing side-effect is the control of energy purchases or the power utility meter.
