Product description
Intended use
The UMG505 is designed for fix mounting in low and
medium voltage switchgear and for measurement of
voltage, current, power, energy and harmonics etc.
Real and reactive energy can be given out via pulse
signal at the digital outputs. The results of the
measurement can be used for controlling
consumers in energy distributions or energy
generation.
The measurement with the UMG 505 can be carried
out in TN-, TC- and IT-networks. Alternating voltage
(50Hz/60Hz) up to 500VAC against ground and
870VAC outer conductor against outer conductor
can be connected directly to the voltage measuring
inputs. The voltage measuring inputs must be
connected via external fuses 2A (medium time lag)
to the UMG505. Voltage over 500VAC against
ground must be connected via voltage transformers.
The voltage measurement via voltage transformers
can be carried out with two or three voltage
transformers by choice.
To the current measurement input, .../5A or .../1A
current transformers can be connected by choice.
In networks with voltage up to 150VAC against
ground, currents up to 5.2A can be connected
directly to the UMG 505 and be measured.
The connection of the auxiliary voltage, the measurement inputs etc. are on the rear side via allinsulated plug connectors. The auxiliary voltage
must be connected to the building installation via a
separation (switch or power switch) and a 2...10 A
overload protection.
A protective wire connection is necessary for
operation of the UMG 505.
Attention!
Measurement in systems with pulse load is
not possible, because no continuous scanning of the measuring signals is carried out.

Functional description
Measurement
The electronical three phase measurement system
determines and digitalizes the effective values of
voltages and currents in 50/60 Hz networks.
Two random test measurements are carried out
each second on all current and voltage measuring
inputs. Signal interruptions, which are longer than
500ms are surely recognized. For each random test
two periods are scanned. The scanning frequency
for a 50Hz signal is 6400Hz. From those sampled
values the microprocessor calculates the electrical
magnitudes.
These measured values are indicated within the
programmable display. Highest values, lowest values and programming data can be saved in a
battery buffered storage.
Selected measured values will be saved with date
and time in a ring buffer.
Measurement in IT-networks
The UMG505 can be used in IT-networks with outer
conductor voltage up to 500V.
Measurement in networks without N
In networks without N, the voltages are measured
against an artificial neutral point (PE). From the
voltage L-PE, the voltage L-L is calculated.
The phase power in networks without N are used for
the calculation of the sum power only, but have no
further meaning.

Hints for installation
Supply voltage
A supply voltage is necessary for the operation of
the UMG 505. The kind and dimension of the
required supply voltage is noted on the type plate.
The supply voltage is connected to the clamps 14
and 15. Between supply voltage (terminals 14, 15)
and ground (PE) a maximum voltage of 300VAC
may occur.
Higher voltage between supply voltage and ground
(PE) can destroy the UMG505. To avoid
overvoltage, the supply voltage should be earthed.
Measuring voltage
The UMG505 is suitable for measurement of
alternating voltage up to 500VAC against ground
and 870VAC between the outer conductors. The
wiring must be suitable for voltage up to 500VAC
against ground and 870VAC between the outer
conductors as well.
Attention!
The UMG505 is not suitable for measurement
of direct current voltage.
Voltage over 500VAC against ground must
be connected via voltage transformers.
For voltage measurement via two voltage
transformers, the „Aron connection“ must be
set in configuration mode of the UMG 505.
The wires for voltage measurement of the
UMG 505 must be protected by an
overcurrent fuse.
Attention!
- The connection wires of the supply voltage
must be suitable for rated voltage up to
300VAC against ground.
- The supply voltage must be protected by a
fuse. The fuse must be in the range of 4A up
to 10A.
- A switch or power switch for the supply
voltage must be provided within the building
installation.
- The switch must be near the device and
easy to reach by the user.
- The switch must be marked as a separation
for the device.
- Please ensure before connecting the supply
voltage, that voltage and frequency match the
statements on type plate!
- The device may be operated with earthed
housing only!
- Cables with sigle soldered wires cannot the
connected via screw terminals!
- The screw terminals may be plugged in
voltage free condition only.
- Only screw clamps with the same pole
number and the same colour may be
connected.
- The supply voltage for the UMG 505 may
not be taken from voltage transformers.
Switching procedures on medium voltage side
can lead to short duration overvoltage, which
can destroy the supply voltage input of the
UMG 505.

Attention!
Current transformers can lead voltage, which
is dangerous to touch and should be earthed.
Current transformers, not loaded at the
secondary, can lead voltage dangerous to
touch and should be short circuited.
Measuring current
The UMG505 is designed for the connection of
current transformes with secondary currents of ../1A
and ../5A. When the device is delivered, a current
transformer of ../5A is set.
Each currrent measurement input can be loaded
with 5,2A over a long period or for 2 seconds with
180A.
Via the current measurement inputs only alternating
current can be measured but no direct current..

Serial interfaces
RS485 (Option)
Terminal resistors
All devices are connected in bus structure (line). In
a segment, up to 32 participiants can be connected.
At the beginning and at the end of a segment the
cable is terminated with resistors. In the UMG505
these terminal resistors can be activated with
pluggable bridges.
For more than 32 participiants a repeater must be
used (amplifier), to connect the single segments.
Protection
For connections via RS485 interface, a twisted and
protected cable must be used. To reach the required
protection, the shield must be connected to housing
parts at both ends of the cable over a wide surface.
Cable type
Unitronic LI2YCYCTPJ2x2x0,22 (Lapp Kabel)
Cable length
1200m at baudrate 38,4k.
RS232 (Option)
The maximum distance between two devices with
RS232 depends on the used cable and the baudrate. The normal distance for a baudrate of 9600
Baud should not exceed 15 up to 30 meters. The
allowed load must be bigger than 3kOhm, The
capacitive load, caused by the transmission cable,
is limited to 2500pF.

LON-Bus (Option)
For the connection of the UMG505 with other LONbus devices a FTT10-transceiver is used within the
UMG 505. Hence, the bus is safed against change
of polarity and can be connected at one or two
sides. Devices, that use a FTT10 -transceiver, can
be connected to each other via line, star or ring
structures.
If the allowed transmission impedance is reached
within a structure, the network can be enlarged by
using repeaters or routers.
Free wiring
For free wiring and bus connection at one end, the
maximum cable length may be 500m, and the
maximum distance between two devices may be
400m.
Bus wiring
For bus wiring and connection at both sides, the total cable length may be 2700m at maximum. The
UMG 505 does not have a connectable terminal
resistor for LON-bus.
Allowed cable length
Depending on the selected structure of the network
and the chosen cable type, different transmission
distances can be achieved.

Putting into service
The device should be put into service as follows:
1. Install the device.
The UMG505 is suitable for panel mounting in low
voltage switchgear, in which overvoltage in
overvoltage class III can appear at maximum.
Any mounting position is allowed.
To ensure safety and functionality of the UMG 505,
a protective wire connection is absolutely
necessary.
2. Connect supply voltage Uh .
The size of the supply voltage Uh for the UMG505
must match the description on type plate. If
supply voltage for alternating current voltage
AC and for direct current voltage DC are
given on type plate, the UMG505 can be
operated with one of these supply voltage by choice.
Connected supply voltage, which do not match the
type plate, can lead to malfunction or damage of the
device.
Between the inputs of the supply voltage Uh
(terminals 14,15) and ground (PE), a maximum
voltage of 300VAC may be attached. Higher voltage
between supply voltage and ground (PE) can damage the UMG 505.
To avoid overvoltage at supply voltage input, the
supply voltage should be earthed.
The cables for the supply voltage must be suitable
for rated voltage up to 300VAC against ground.
3. Program current and voltage
transformers
Ꮨ
4. Connect measurement voltage.
The UMG505 is suitable for the measurement of voltage up to 500VAC against
ground and 870VAC phase to phase.
The UMG505 is not suitable for the measurement of direct current voltage. Voltage over
500VAC against ground must be connected via
voltage transformers.
For voltage measurement with two voltage transformers, „Aron Circuit“ must be entered within the configuration of the UMG 505.
After the connection of the measurement voltage,
the indicated values for voltage L-N and L-L must
match the ones at measurement voltage input. If a
voltage transformer ratio is programmed, it has to
be respected during this comparison.
Page 19
19
= Key1
= Key 2 = Key 3
= Max. value or consumption = Min. value or supply
Ꮨ
5. Connect measurement current.
The UMG505 is designed for the connection
of ../1A and ../5A current transformers.
When the device is delivered, a current
transformer of ../5A is set.
Each current measurement input can be loaded with
5.2A for long duration or 180A for two seconds.
Over the current measuring inputs only alternating
current, but no direct current can be measured.
None earthed transformer clamps can be dangerous
to touch. Current transformers, which are not loaded
on the secondary can lead voltage dangerous to
touch and should be short circuited.
The current measurement inputs should be connected one after the other. Please compare the
current indicated by UMG 505 with the attached
current.
If the current transformer is short circuited, the UMG
505 must show zero A in the corresponding outer
conductor.
The current indicated by UMG505 must match the
input current respecting the set current transformer.
6. Check measurement.
If all voltage and current inputs have been
connected correctly, the phase and sum power is
calculated and indicated correctly.
Check all phase power
If a current transformer is assigned to the wrong
outer conductor, the corresponding phase power is
indicated incorrectly.
The assignment of the outer conductor to current
transformer is correct, if no voltage between the
outer conductor and the corresponding current
transformer (primary) appears.
To ensure, that an outer conductor at voltage
measurement input is assigned to the right current
transformer, the corresponding current transformer
can be short circuited on the secondary. The
apparent power, indicated by UMG 505 must be
zero in this phase.
If the apparent power is displayed correctly, but the
real power shows a „-“ sign, the current transformer
clamps are exchanged or power is supplied to the
energy supplier’ network.
Check sum power
If all voltage, current and power are displayed
correctly for the corresponding outer conductors, the
sum values must be correct as well. This can be
confirmed by comparing the measured sum power
with the energy, measured by the KW meter in the
distribution.

Harmonics
Harmonic waves are the integer multiple of the fundamental. The UMG505 measures the fundamental
of voltage in the range of 45 up to 65Hz. The
calculated harmonic current and voltage are related
to this fundamental. For strongly distorted voltage,
the fundamental cannot be detected with sufficient
accuracy. In order to calculate the harmonics
nevertheless, a fix fundamental can be assumed
with either 50Hz or 60Hz. Please see chapter
„Scanning frequency“.
The UMG505 calculates harmonics up to the 20th.
Total harmonic distortion THD(f)
The calculated total harmonic content THD(f)
represent the effective ratio of harmonics to the fundamental. The total harmonic distortion is given in
%.

EMAX
Real power EMAX
For the real power the mean value real power
EMAX is build over a programmable measurement
period additionally. Here the measured value „sum
real power“ is summarized each second and divided
by the measuring period time. As a result, each second a new mean value „real power Emax“ is at
disposal. At the end of a measuring period, the sum
is deleted, and the measuring period starts again.
For the comparison and storage of the monthly
Emax peak values, only that real power Emax is
used, which was measured at the end of a period.
Monthly EMAX peak values
All monthly EMAX peak values are saved for all
EMAX target numbers each month. The old monthly
EMAX peak values are overwritten at the beginning
of a new year.
If the real power EMAX is configurated for the
display software PSW505, real power EMAX can be
indicated in the display of the UMG 505 as well.
The monthly EMAX peak values can be read out
directly at the UMG505 and via the serial interface,
with the software PSW505, for instance.
EMAX target number
Attention!
The „Monthly EMAX peak values“ are not
indicated in the standard display configuration, when the device is delivered.
Those indications can be configured with the
software PSW505, which belongs to the
contents of delivery.
Pulse input
The measured value „Sum real power“ is calculated
from the measured current and voltage, when the
device is delivered. But if a pulse valence is
assigned to „Digital Input 4“, „sum real power“ is
calculated from pulse number and valence. The real
power of the single phases will be calculated by the
current and voltage, which the UMG 505 measures
furthermore.
Target values
For the EMAX program in the UMG 505, 5 targets
can be given. If no more settings were made, the
target 1 is active. Via the input channels 1-16 and
via the switching clock, one of the 5 target values
can be selected and assigned to the Emax program.
If a target value is activated via the input channels
and at the same time another via the switching
clock, the target with the highest number (priority)
of Emax program is used.

Measuring period
(Example
15Minutes).
Reset of the measuring period
The averaging time for real power Emax is called
measuring period.
The measuring period for real power Emax can be
5, 10, 15, 30 and 60 minutes. The manufacturer’s
setting is 15 minutes.
To be synchronized with the measurement of the
energy supplier, the reset of the measuring period
should be carried out via an input of UMG 505. If no
reset via an input of UMG 505 occurs within the programmed measuring period, the reset is released
automatically by the internal clock.
The reset of the measuring period deletes real power Emax and starts a new measuring period. The
last measured real power Emax is used for the
minimum and maximum storage and, if programmed, saved in the event memory.
If there are less than 30 seconds between two
resets, the measuring period is reset and real power EMAX is deleted. The obsolete measured value
is not saved in the maximum and minimum memory
and not be deposited within the event memory, if
programmed.
The measuring period for real power EMAX can be
reset by the following means:
- automatically, after measuring period,
- internally, via keyboard,
- internally, via digital inputs,
- externally, with MODBUS Protocol,
- externally, with LON Bus.
The automatical reset after measuring period cannot be suppressed.
Press

Memory
The memory of the UMG 505 is deviced into three
ranges. The event memory, the maximum and
minimum memory and the ring buffer. The event
and the ring buffer can be read out with the program
PSW505 and PC only. The data which are read out
by PC are available in ASCII format.
In the minimum and maximum memory, the
minimum and maximum values are deposited with
date and time.
All monthly EMAX peak values are saved for all
tariffs each month. The obsolete monthly Emax
peak values are overwritten at the beginning of a
new year.
Event memory
In the event memory, the following events can be
saved with date and time:
- Deletion of event memory,
- Change of the digital inputs,
- Change of the digital Emax outputs,
- Breakdown and return of the supply voltage,
- Breakdown and return of the measurement
voltage,
- Threshold violations.
The event memory can be read out with PC and the
programming and reading out software PSW505
only.
The breakdown of the measurement voltage will be
recognized, when:
- the measurement voltage is smaller than
50% of the set primary of the voltage
transformer,
- and the breakdown remains longer than
500ms without interruption.
In the device, a part of the memory is available,
which are shared by the ring buffer and the event
memory. Here, the size of the event buffer can be
set in menu „Prot“ by programming the number of
saved events. If the number is set to "0", the whole
memory is available for the ring buffer.
If the number of events, that are saved, are
changed, the event memory and ring buffer are
deleted.

Ring buffer
For the most measured values a mean value is
calculated (please see table "Measured and
calculated values"). Mean values are marked with a
horizontal bar above the measured values. The
mean values, selected for storage in the ring buffer,
are marked by both of the arrow symbols.
For the storage in ring buffer, the following values
can be selected in menu PRG of the UMG505
- the mean values of measured values,
- the EMAX reset of the measuring period and
- a part of the energy meters (Tx0)
The changeable energy meters (see table below)
can be selected with the programming software
PSW505 only for saving in the ring buffer.
For energies, the period between two savings is set
to one hour.
Storage duration
The more mean values are marked for saving in the
ring buffer, the shorter becomes the storage
duration. When the device is delivered, the setting
Mean values: U1, U2, U3, I1, I2, I3, P1, P2, P3
Averaging time: 15 Minutes
leads to a storage duration of about 1 year. If this
time is exceeded, the most obsolete values are
overwritten.
If various averaging times are assigned to the mean
values, more memory is required, and the storage
duration becomes shorter.
To enlarge the storage duration, the number of
saved values can be decreased, or all values should
be programmed for saving with the same averaging
time.
Attention !
A change of
- the averaging time,
- the measuring period,
- the current transformer ratio,
- the voltage transformer ratio,
- the measurement (Aron circuit) or
- the measured value selection for ring buffer
delete the ring buffer.
The more mean values are selected for storage in
the ring buffer, the earlier the ring buffer is complete
and will be overwritten. The period of storage for the
ring buffer can be read out in the measured value
indication.
The stored measured values can be read out of the
ring buffer using the "programming- and reading out
software PSW505" only.

Ring buffer data format
Data sets can be saved in compressed or uncompressed form. With the presettings, the data are
saved compressed.
The programming and reading out software
PSW505 can read compressed data from ring buffer only. Other applications can read data sets in uncompressed form only.
An uncompressed data set consists of the type of
measured value, the date and the measured value.
This value is always given in Float format.
1)
r/w = read/write
2)
Measured values {float: Actual value[L1, L2, L3], Mean value[L1, L2, L3], Minimum[L1, L2, L3], Maximum[L1, L2, L3]}
Changeover ring buffer
The changeover from compressed to uncompressed data is carried out via the serial interface
and Modbus protocol.
If data should be saved uncompressed within the
ring buffer, address 19010dez must be overwritten
by 2 Bytes of a content by choice.
If data should be saved uncompressed within the
ring buffer, address 19020dez must be overwritten
by 2 Bytes of a content by choice.
Type of measured value
The type of the measured value can be determined
by the addresses from the tables 1a and 1b.
Example: If the type is marked by the decimal number „1004“, this corresponds to the current mean
value in phase L2.
Date
In the part of the data set with the description
„Date“, the date and time of the measurement are
saved.
char: Year, Month, Day, Hour, Minute, Second

Read ring buffer
If the data sets have been saved uncompressed,
they can be read via the serial interface with
Modbus protocol.
To make this reading easy, there is a ring buffer
pointer available. This ring buffer pointer always
points to the beginning of a data set. One data set
consists of 12 Bytes.
Attention!
If another way of compression is selected,
the total content of the ring buffer is deleted.

Read data sets
The reading of data sets is controlled by the following addresses:
Read address 19000dez.
The first 4 Bytes provide the contents of the ring
buffer pointer.
The next 12 Bytes provide the first data set, which
the pointer points on.
The ring buffer pointer is increased automatically
by the number of read Bytes, but the first four Bytes
are not included.
Write address 19000dez.
Set ring buffer pointer on a data set of the ring
buffer.
If the ring buffer pointer is overwritten by 0000, it
points on the last read beginning of ring buffer with
address 19008
dez.
Read address 19002dez.
Read a number (4 Bytes) of data sets from that
address on, on which the pointer points. The ring
buffer pointer is increased automatically by the
number of read Bytes. The number of read Bytes
must be divisible by 12.
Read address 19004dez.
Provides that address (4 Bytes), on which the actual
pointer points.
Read address 19006dez.
Read a number of data sets, from that address on,
on which the pointer points. The ring buffer pointer
is not increased.
Read address 19008dez.
Delivers the number (4 Bytes) of the Bytes saved in
ring buffer. If you divide this number by 12, the result
is the number of the saved data sets.
The ring buffer pointer is set to the last data set in
ring buffer. The contents of this pointer is therefore
zero.
Overwrite address 19010dez with 2 Bytes with a
content by choice
New data sets are written into the ring buffer uncompressed. If data were saved before in a compressed
form, the ring buffer will be deleted.
Read address 19010dez.
Delivers the storage format of the ring buffer in 2
Bytes.
00=compressed ring buffer
01=uncompressed ring buffer
Overwrite address 19020dez with 2 Bytes with a
content by choice.
New data sets are written into the ring buffer
compressed. If data were saved before in a uncompressed form, the ring buffer will be deleted.
Overwrite address 19030dez with 2 Bytes with a
content by choice.
The ring buffer will be deleted.
Example 1: Read the last saved data set.
Read adress 19008
dez. The ring buffer pointer
(0000) is set to the last data set in ring buffer.
Read 12 Bytes from address 19006
dez. 12 Bytes
correspond to one data set. The ring buffer pointer
is not increased.
Example 2: Read all saved data sets.
1.) Read address 19008
dez. The number of saved
Bytes is read. If you divide the result by 12, the number corresponds to the saved data sets. The pointer
points to the last saved data set in ring buffer.
2.) Read the content of the Bytes in ring buffer by
address 19002
dez. With the MODBUS-Protocol, at
maximum 240 Bytes=20 data sets can be read per
reading. The number of read Bytes must be divisible by 12.
The ring buffer pointer is increased automatically by
the number of read Bytes and points to the next data
set, which has not been read yet.
3.) Repeat reading of address 19002
dez as long as
all data sets have been read.
Attention!
If a failure appeared during data transmission,
the complete procedure must be repeated,
starting with step 1.
Example 3: Read all saved data sets.
1.) Read address 19008
dez. Reads the number of
saved Bytes in ring buffer. Divided by 12, the number of saved data sets is the result. The pointer
points to the last saved data set.
2.) Read address 19000
dez. The first 4 Bytes refer
to the actual address of the pointer. The next 12
Bytes provide the first data set of the ring buffer.
With MODBUS-Protockol you can read 244Bytes
(4Byte + 20 data sets) at maximum per reading.
3.) Repeat reading address 19000
dez as long as all
data sets have been read.
Attention!
If a failure occured during data transmission,
the last actual address of the ring buffer
pointer must be written on address 19000
dez
and the last reading procedure must be
repeated.

LON interface (Option)
For the connection of UMG505 with other LON-Bus
devices, a FTT10-Transceiver is used within the
UMG 505. The bus is proof against change of
polarity, and can be connected to one side or both
sides. Devices which use a FTT10- Transceiver,
can be linked to each other via line star or ring
structures.
If the allowed transmission resistance in a structure
is reached, the network can be expanded by the use
of repeaters or routers only.

Net frequency
The net frequency is determined from the measurement voltage within the UMG 505. From the net frequency the scanning frequency for the current and
voltage inputs is calculated.
For measurements with very distorted voltages, the
frequency of the voltage fundamental cannot exactly
be determined any longer. Voltage distortion occurs
in measurements at consumers, which are driven
with phase changing controllings.
For highly distorted measurement voltage, the
corresponding net frequency should be programmed.
Distortion of the current does not affect the determination of the frequency.
Without measurement voltage, no net frequency can
be determined, and no scanning frequency can be
calculated. Voltage, current and all resulting values
are not calculated and indicated with zero.
If the current should be measured without measurement voltage, the net frequency must be programmed at UMG 505.
The determination of the net frequency can be
carried out automatically or as a fix frequency.
The following settings for the determination of the
frequency are at your disposal:
"Auto" Automatical frequency
"50"Hz Fix frequency
"60"Hz Fix frequency
The proceeding for the determination of the frequency can be called up and changed in the menu

Switching clock
The switching clock of the UMG505 has 100
switching clock channels. Each switching clock
channel describes a certain period. The period is
described by a switch-on time and switch-off time.
The switch-on and -off time is determined by the
day, hour and minute.
Each switching clock channel can control a
switching clock output, and select an Emax target
value and an energy meter.
In the programming of the digital outputs, a „Digital

EMAX target value (Option)
For the EMAX-Program, up to 5 EMAX target values
can be programmed. To each target, a target
number is assigned (1-5). The changeover of the
target is effected via the EMAX target numbers. The
changeover can be selected via the internal clock
or the digital inputs of the UMG 505.
EMAX digital outputs (Option)
Connection power and connection time
The EMAX program can control up to 5 Emax digital outputs. Each Emax digital output can have a
priority 0 ... 9. EMAX outputs with priority 0 are not
considered in the trand calculation of the Emax program. EMAX outputs with low priority, example 1,
are disconnected at first and reconnected at last.
EMAX outputs with the same priority have equal
rights. Only if all Emax outputs of the same priority
have been disconnected, the next priority will be
considered for disconnection.
To determine the time of switching more accurate,
each Emax output must be programmed with its
connection power, which means the power of the
connected consumers.
The assigned switching times are held in any case.
The minimum connection time describes, for how
long a consumer must be connected between two
disconnections.

EMAX analogue outputs
The UMG505 has 5 digital and 4 analogue Emaxoutputs internally. Each internal Emax analogue
output can be assigned to an „analogue output“. If a
generator should be controlled by an Emax
analogue output, the internal Emax analogue output
cannot only be assigned to an „Analogue Output“,
but also to a „Digital Output“. The „Digital Output“
is active, when the calculated current of the Emax
analogue output is bigger than 0mA. Therefore, this
„Digital Output“ can be used as a starting signal for
generator control.

Generator control
The Run up time is here the time, which the
generator needs to supply its power after switching
on.
The minimum running time is the time, which the
generator must run, before it can be disconnected
again by the UMG 505.
The speed, with what the analogue signal is changing, is 2% of the difference from maximum
connection power less minimum connection power
per second. The speed cannot be changed directly.
Consumer control
The run up time sets a limit to the starting speed of
the consumer’s power. To reach maximum
connection power from minimum connection power
takes the run up time.
The maximum spare power represents the power,
that may be spared within one measuring period.

Digital Inputs
The UMG505 has 20 internal inputs. On the internal
inputs 1 to 4, the 4 optical inputs (
digital inputs 1-4
)
are handled. On the internal inputs 5 to 12 the 8
inputs of the LON-Bus interface (Option), and on the
internal inputs 13 to 20 the 8 inputs of the MODBUS
interface (Option) are handled.
The condition of the digital inputs

) can be combined
by AND and the result can be assigned to an input
channel. In this case, both digital inputs must be
active to activate the assigned input channel.
Each of the

Activate energy meter
In UMG505 up to 30 energy meters are at your
disposal. The 6 energy meters Tx0 can only be
deleted, but not deactivated. The other 24 energy
meters can be deactivated. Only active energy
meters count the occurred energy. The changeable
energy meters are marked grey in the following diagram.
The changeover of the energy meters is carried out
via the input channels 1-16 or via the switching
clock. An energy meter is active, when it is activated
via an input channel or the switching clock.
Changeover of EMAX targ. val. (Option)
For the EMAX program, up to 5 targets can be valid. If not otherwise programmed, target 1 is active.
Via the input channels 1-16 and via the switching
clock, one of the 5 targets can be selected and
assigned to the EMAX program.
If the target is activated via the input channels, and
another target simultaneously by the switching
clock, the target with the highest target number is
used by the EMAX program.

EMAX measuring period reset
The reset of the measuring period should be carried
out via an input of the UMG 505 to run synchronized
to the energy suplliers measurement. If no reset is
carried out at the input of the UMG 505 within the
programmed measuring period, the reset is done
automatically, effected by the internal clock.
The reset of the measuring period deletes the
EMAX real power and starts a new measuring
period. The last measured EMAX real power is used
for minimum and maximum storage and, if programmed, saved in event memory.
Synchronize internal clock
Inaccuracies of the internal clock can be corrected
by synchronization via one of the internal inputs. If
the internal input, which is assigned for
synchronicity, is active, the clock in UMG 505 will
be set to the nearest full hour.
Example 1
If the UMG 505 shows a time of 15:05h, the clock
will be corrected to 15:00h..
Example 2
If the UMG 505 shows a time of 15:35h, the clock
will be corrected to 16:00h..

Pulse valence
With the manufacturer’s settings, the measured
value „sum real power“ is calculated by the real power of the single phases.
If a pulse valence is assigned to „digital input 4“,
the measured value „sum real power“ is calculated
by the incoming pulses of „digital input 4“, and
changes at the input are no longer registered in
event memory.
The EMAX program (Option) in UMG505 uses the
measured value „sum real power“ for the control of
disconnection and connection of the consumers and
generators.

Digital Outputs
The UMG505 has 5 digital transistor outputs. These
outputs are depicted with out1 to out5 in display.
Each output can be assigned to different data
sources. There are 7 different data sources at
disposal:
Threshold outputs,
Switching clock outputs,
EMAX digital outputs,
EMAX analogue outputs,
LON-Bus (Option),
MODBUS,
Energy meters T00 - T04, T30 - T34,
T10-T24, T20 - T24.
Each data source can be assigned to one output
only. If the output is assigned to an energy meter,
the output works as pulse output.
The signals from all data sources except the energy
meter, can be inverted.

Analogue outputs
Source, destination and scale
The UMG505 has 4 analogue outputs. The
analogue outputs have a common earth and are
separated galvanically against the other inputs and
outputs of the UMG 505. For the operation of the
analogue outputs, an external auxiliary voltage of
20V to 30V DC is required.
The maximum burden may not exceed 360 Ohm. If
the analogue output is loaded by a bigger
resistance, the output range (20mA) is limited.
To each analogue output, a range of 4-20mA or 020mA can be assigned.
The following sources can be used for the analogue
outputs:
- Measured values,
- The internal EMAX analogue outputs 1-4 and
- Values, which are transmitted to UMG 505 via
Modbus.
Only measured values, which are configured for the
measured values indication, can be given out by the
analogue outputs. The measured values of real
energy and reactive energy cannot be given out by
the analogue outputs.

Example: Sum real power
The sum real power must be given out via analogue
output of UMG 505. As sometimes a generator is
connected, also that power shall be transmitted,
which is delivered to the energy supplier. Real power supply is marked be a „-“ before the measured
value.
The following settings are required:
Output range = 0 .. 20mA
Measured value = Sum real power
Scale start value = -100kW (supply)
Scale end value = 400kW (consumption)
With the selected settings, a range of 100kW +
400kW = 500kW is covered. Therefore: 500kW =
20mA.
1mA means 500kW/20 = 25kW.
If no real power is consumed or supplied, a current
of 4mA flows.
If real power is supplied, the current is smaller but
4mA.
Example: cos(phi)
Output range = 4 .. 20mA
Scale start value = 0.700inductive
Scale end value = 0.900capacitive

Serial number
Each device has its 8 digit serial number, which cannot be changed by the user.
For several devices, even after delivery a release of
certain functions is possible. In this case, the serial
number of the device is needed in the manufacturing works.
For each device there are passwords deposited in
the producing works for releasing the functions
(options).
Software Release
The software within the device is ammended and
expanded continously. The software issue of the
devices are therefore marked with a software
release. The software release cannot be overwritten
by the customer.
Select
Scroll to indication of
the software release
in menu CONF with
key 3
.
In this example, the
software release is
indicated with 2.010.
The software release can be called up in menu
CONF. Please change into menu CONF (see
chapter "Configuration").
Example:
Serial number = 5400 0003

PSW505
The programming and evaluation software PSW505
belongs to the contents of delivery of the UMG505.
With this software, you can
- Configure the display,
- Read out event memory and ring buffer and save
it to PC and
- Read, change and save configuration by PC.
For the operation, a PC with COM interface and
Windows® operating system is required.
The connection between UMG 505 and PC can be
carried out via RS232 or RS485 interface, depending on the version of UMG 505.
If the UMG 505 has a RS232 interface, the connection to PC is carried out via zero modem cable.
If the UMG 505 has a RS485 interface, the connection to PC must be carried out via an interface converter.
Functions
Configure the UMG505
A simple configuration of the UMG 505 can be done
directly via the three function keys and display. But
the more comfortable way of programming the UMG
505 is possible with the function "Configuration of
UMG505" with PSW505 and PC. Configurations can
be saved on PC. Only the measured value
indications can be printed.
Configure measured value indications
With the manufacturer’s presettings, only a part of
the possible measured values is indicated by UMG
505. This program part allows:
- To read the actual configuration of the measured
value indications.
- To load a configuration of the measured value
indications from PC.
- Determine the sequence of the indicated
measured values.
- Load the configuration of the measured value
indications into UMG 505.
- Save the configuration of the measured value
indications to PC.
Read memory
The memory of the UMG 505 is divided into three
ranges:
the event memory,
the ring buffer and
the storage for minimum and maximum
values.
The event memory and ring buffer can be read out
by PC only. The minimum and maximum values can
be called up at UMG 505 directly via the keys.

Within the UMG 505 almost all measured values are
available in floating point format (Table 2). For the
transmission of measured values the floating point
values are recalculated in integer format by the
UMG 505, such as char, int and word (Table 4).
To lose no digits after decimal point, the value, that
should be transmitted, is scaled. The opening value
from UMG 505 is calculated as follows:
Measured value = Transmitted value * Factor
The scales of the measured values are calculated
from UMG 505 out of current and voltage
transformer ratio. Here the minimum definition of the
transmitted value of 0,1% is strived for.
The scales of the UMG 505 can be retrieved under
the following addresses:
Example
Transmitted value UMG 505 = 2301
Programmed scale = -1
Which voltage is measured by the UMG 505?
From the scale table, you can read the factor =/10
for scale=-1:
Measured value = Transmitted value * Factor
Measured value = 2301 * 1/10
Measured value = 230,1V
The measured voltage is 230,1V.
