Measurement Process
The EMU Professional II measures current and voltage as follows:
The EMU Professional II measures current and voltage each for 1 second after
which the next measurement starts. During this second the following procedure
happens: The EMU Professional II records 2520 measu rement points for current
I and voltage U each. These measurement points have a resolution of 32bit. All
measurement values for both the current I and voltage U are squared, added up
and divided by the number of measurement points (2520) at the end of the
second. After this second the EMU Professional II calculates the square root
of this value to get the RMS value for both current and voltage:
c U12
+ U22 + ¨ ¨ ¨ + U7268 2520
=
Uef f
c I12
+ I22 + ¨ ¨ ¨ + I7268 2520
=
Ief f
At the same time the following integral is calculated:
U ¨ I dt
Multiplying Urms and Irms results in the apparent power S:
S = Ueff ¨ Ieff
The power factor (cos) is calculated with:
U ¨ I dt = S
And the active power :
P =F ¨S
The calculated integral of current and voltage, as well as power ensures the coverage of nonsine currents up to the 7th harmonic.

Installation
The EMU Professional II is not dependent on location or position. The meter is
designed to fit on 35mm DIN rails (EN 50022) or to be installed with a front
installation frame. To remove the meter from a DINrail just pull the spring
loaded bolt on the underside. The meter weighs about 400g. To ensure most
efficient installation and service of the EMU Professional II meters we
recommend using indirect metering such as EMU Professional II 3/5 meters for
installations where a quick and inexpensive shut down of the installation is
not possible.
Attention: The installation of the meter must be carried out by qualified and
trained personnel. Current transformers must not operate open loop as high
voltages can occur. These voltages can lead to personal and property damage.
DANGER: Make sure that all connected wires are voltage free before you install
/ change or check the meter. Touching any live elements is dangerous to life!
DANGER: The EMU Professional II 3/5 has voltage on the current path! Make sure
that the voltage connections are voltage free before you install the current
transformer. Touching any live elements is dangerous to life!
Attention: According to DIN VDE 0100557, Punkt 5.3.1, the secondary winding of
current transformers must not be grounded in lowvoltageinstallations!
Attention: Only use the intended screw and spring clamps to connect your
meter. It is recommended to use end sleeves.
Attention: Nonobservance of mounting and installation instructions may lead to
damage or destruction of this meter. Please keep to the instructions.

Real Time Clock (RTC)
The real time clock of the EMU Professional II can be set directly on the
energy meter or over optional interfaces. The TCP/IP interface allows for a
connection to a time server which allows the meter to synchronize itself. The
EMU Professional II has an internal clock with a daily deviation of 0.4
seconds. The LP Version of the EMU Professional II has special notifications
based on the RTC that can pop up on the display. For more information on the
LP version of the EMU Professional II please consult the PTBA 50.7 specific
chapter at the end of this user manual.
Configuration on the Device
The realtime clock can be set directly on the EMU Professional II via the
control buttons. The internal RTC is buffered with a supercap for at least 12
hours while the power is out leading to fewer RTC settings because of
brownouts / blackouts. The meter must be powered on for at least 2 hours
beforehand to charge the supercap.
Note: Make sure to start from the right and edit to the left if you set the
time via the buttons. , “Arrow right” to settings , “Arrow down” to Realtime
Clock , Press “SRVC” button (<2 seconds) , “Arrow right” chooses the digit,
“Arrow down” increments the digit , Save: Press “SRVC” button (>2 seconds)
until the LCD flashes
Configuration over External Interfaces
You can set the time while configuring the MBus via the EMU MBConnect
software.
Automatic Synchronization
Time synchronization on MBus meters happens through a defined command. The
answer entails information about time and date. The meter synchronizes
immediately and sends an “ACK” message back as acknowled gement. The time can
only be set once per record interval. Meters with the TCP/IP Interface can
synchronize themselves if an NTP time server is specified. For the first
synchronization the meter sends timerequests every 12 minutes. After the first
successful synchronization the request interval goes to once every hour.
Note: Projects with the obligatory load profile certification PTBA 50.7: Only
2048 entries for a RTC synchro nization (or transformer ratio adjustment, S0
ratio adjustment or S0 impulse duration adjustment) are possible before the
meter falls into nonvalid state. Transformer ratio adjustments can only be
done once every load profile interval (15 min).

Configuration Interfaces
The EMU Professional II can be fit with several interfaces. There is only one interface possible per meter.
Interfaces
The EMU Professional II possesses one of the following optional interfaces:
, MBus , ModBus RTU , TCP/IP mit Modbus TCP/IP , LoRa
Note: A EMU Professional II only ever possesses one of these interfaces.
You can configure your EMU Professional II via different means. One such means
is directly on the meter via the touchsensitive buttons. If you use your EMU
Professional II in conjunction with a EMU MBus Center you can configure the
EMU Professional II via the webuserinterface of the EMU MBus Center.
Note: The meter must be connected via MBus to the EMU MBus Center for this.
MBus
The MBus interface is implemented according to EN 137572,3 (formerly EN14343).
Therefore the EMU Professional II MBus can communicate with all MBus capable
devices. The MBus interface is integrated into the meter and protected from
contamination and manipulation. The interface is located at the back of the
meter on pin 1[3] (+) and pin 2[4] (). Please consult the document “Manual EMU
Professional II MBus”, DocRef 1480 for further information on the MBus
interface of the EMU Professional II.

In Case of Errors
In case you encounter an error on the EMU Professional II please consult the following list of common errors.
Possible Errors after Installation
One or more phase currents show a negative sign: Check if the connections “S1”
and “S2” (“Lx” and “Lx” for the direct meter) of the corresponding phase are
connected correctly. “S1” (“Lx”) is always connected on the grid side,
S2″(“Lx”) always on the user side.
DANGER: Make sure that all connected wires are voltage free before you check or change any connec tions. Touching any live elements is dangerous to life!
Wrong Meter Readings on the Converter Counter
The EMU Professional II displays a way higher consumption than possible:
Please ensure that the current and voltage transformer ratios are set
corresponding to the used transformers. The two ratios can be set on the EMU
Professional II via the two buttons.
5/5 up to 20’000/5 A, in 5 Asteps. 1/1 up to 4’000/1 A, in 1 Asteps.
Behavior with Export and Import
The EMU Professional II records the energy flow in both negative (export) as
well as positive (Import) direction in separate registers. The meter readings
of import or export are never counted down or decreased. All registers are
accumulating.
The register “Active Energy Import” adds up all the imported energy from
external sources. For this energy the customer receives an invoice from the
local utility company. The register “Active Energy Export” adds up all the
exported energy from you own sources (e.g. photovoltaics). For this energy the
customer receives payment from the local utility company.
Practical example:
Current consumption of your complex at 1 pm: Phase L1: 10kw Phase L2: 20kw
Phase L3: 30kw Total ==> 60kw
Current export of your PV installation on this complex at 1 pm: Phase L1: 25kw
Phase L2: 25kw Phase L3: 25kW Total ==> 75kW
In this case you produce more power than your complex needs right now. The
register “Active Energy Import” stays the same while the register “Active
Energy Export” is increasing as you are exporting your surplus energy.
The EMU Professional II Sends Wrong Information on the S0 Interface
Check if the pulse rate and pulse duration of the EMU Professional II
correspond with the ones of your receiver. The pulse rate as well as pulse
duration can be configured via the two buttons. Possible pulse rates /
durations: Pulse rates: 1, 10, 100, 1000 and 10000 Impulse per kWh/kvarh.
Pulse duration: 2ms, 10ms, 30ms, 40ms and 120ms.

EMU Professional II
The following chapter describes the menu items relevant to the load profile in
greater detail. The load profile of the EMU Professional II is certified for
PTBA 50.7.
42
User Manual EMU Professional II
CT Ratio and VT Ratio
These ratios set the applied factor while measuring the energy and must be set
according to the used current and/or voltage transformers. The adjustment of
these ratios is only possible using the SRVC button. The SRVC button can be
sealed with a lead seal.
Real Time Clock
The real time clock (RTC) displays the currently valid time of the device. We
recommend setting the RTC to UTC as the meter does not support timezones and
daylightsaving time.The adjustment of the real time clock is only possible
using the SRVC button. The SRVC button can be sealed with a lead seal.
S0 Impulse Output
The S0 Impulse output can be set to the following:
, Active Energy Diff All active Energy, either import or export, is output
without differentiating. , Reactive Energy Diff All reactive Energy, either
import or export, is output without differentiating. , Active Energy Import
Only active energy import is output. All other energies are ignored. ,
Reactive Energy Import Only reactive energy import is output. All other
energies are ignored. , Active Energy Export Only active energy export is
output. All other energies are ignored. , Reactive Energy Export Only reactive
energy export is output. All other energies are ignored.
The interface outputs an electrical pulse per set energy unit. The interface
can be configured as follows:
, Impulse ratio: Set the amount of pulses per unit of energy measured. ,
Impulse length: Set the length of the pulse.
Use for Billing Purposes
The LP version of the EMU Professional II is only certified for billing
purposes of active energy measurements. These measurements can be accessed at
any time over the display or the meter’s interface All other measurements are
purely of an informative nature and may not be used for billing purposes. All
measurements not shown on the display but retrievable over an interface are of
a purely informative nature as well and may not be used for billing purposes.
Description
The load profile functionality according to PTBA 50.7 consists of 2 separate
functionalities:
, The load profile storage for the recording of measurements.
This storage space is a ring buffer. After reaching the maximum possible
entries, the oldest 27 entries are deleted and overwritten. This overwriting
happens in batches of 27 entries due to technical factors.
, The logbook storage (official calibration certified logbook) for the
recording of changed made to the para meters relevant for the load profile.
The logbook cannot be tampered with without destroying the adhesive seal
labels. The changes that are recorded are the following: Adjustment of time
and date , An adjustment of time and date is defined as follows: The
difference between old and new time is more than 9 seconds. If the difference
is smaller than 9 seconds, the adjustment is interpreted as automatic time
synchronization and will therefore not be recorded. Adjustment of voltage of
current transformation ratio. Adjustment of S0 impulse ratio, S0 impulse
duration
43
User Manual EMU Professional II
Each of the values mentioned above can only be adjusted once in every
measurement interval. The next change can only be made in the next interval.
Internal memory only suffices for 2048 logbook entries. These entries can
neither be deleted nor overwritten. Once this logbook memory is depleted the
meter goes into the “not certified” status if one of the parameters mentioned
above is changed again. Once this status is set, a “PTB NV” message is shown
on the display. All measured load profiles after this setting are marked as
“NV” (Not valid).
Note: This “NV”Status of the meter cannot be reversed in any way due to legal
restrictions.
Interval of Recording
The interval for recording load profiles is fixed at every 15 minutes and
cannot be changed.
Time Synchronization
Synchronizing of the time may be done over a predefined command over the
MBus/TCPIP interface. The data sent includes time and date. The
synchronization is immediate and is acknowledged by the meter with a “ACK”
message. The time can be synchronized or set only once every measurement
interval (15min). The time set must be the legal time. An internal buffer
supplies the RTC for at least 18 days (The meter needs to be powered for at
least 2 hours to charge this buffer). The EMU Professional II LP
differentiates between the following two time adjustments:
, Synchronization: If the difference between old and new time is less than 9
seconds (1% of load profile interval) the meter sets the new time without
generating a logbook entry.
, Time set: If the difference is more than 9 seconds the time change will not
count as a regular synchroniz ation and will generate a logbook entry.
Note: The EMU Professional II operates with internal timestamps therefore it
knows if more than 2 weeks have passed since the last synchronization even if
it is powered down for more than 2 weeks (but less than 18 days). The
notifications TNV, TNS or NTP can appear on the display. The following diagram
explains when and why they appear and the consequences:
44
User Manual EMU Professional II
Note: According to the PTBA 50.7 Certificate the time must be synchronized at
least once every 2 weeks. If no synchronization occurs within these 2 weeks
all load profiles after these 2 weeks are marked as “NV” until the next
synchronization occurs. The message “TNS” is displayed.
Note: Ex Factory the internal buffer for the RTC is not charged. 45
User Manual EMU Professional II
Tariff Changes
A change of tariff on the LP version is set at the beginning of the next
interval. A tariff is therefore always set for at least one interval period.
For the LP version only the tworate tariff is available.
Note: It is possible for a wrong tariff to be displayed after a power failure.
The first load profile is set as “NV” regardless and the correct tariff is set
correctly at the start of the next interval according to the tariff inputs
NE,E1 and E2.
Note: For load profile measurements according to PTBA 50.7 the tworate tariff
is mandatory. Tariff chan ges are set at the start of the next regular
interval.
External Readout over Interfaces
Readout over external interfaces can be used for billing purposes. The
interfaces send the same information as is shown on the display.
Memory Capacity
The internal memory capacity can store:
, Continual entries for the load profile: 105378 With a save interval of 15
minutes this memory capacity can store load profiles reaching back approx. 3
years. Once the last entry is stored the memory handler deletes the first 27
entries and jumps back to the first entry. Once all 27 entries are filled
again, the next 27 entries are deleted. This means only the newest 105351 load
profile entries are available and older ones are deleted.
, Logbook entries: 2048 Each adjustment of the current or voltage ratio, the
real time clock or the S0 interface results in an entry into the logbook. Once
all 2048 entries are used the meter sets all load profiles after the next
change to one of the above factors to “NV” according to PTBA 50.7. A meter in
this status must be replaced.
Power Failure and Reboot
Power Failure All load profiles are saved and stored in a fixed 15minute
interval e.g. XX:00, XX:15, XX:30 and XX:45. After a power failure, the normal
interval continues. An Example:
, Current time: 07:37 => last load profile entry was at 07:30 , Power failure
until 08:12 , Next entry happens on schedule at 08:15 (This entry is marked
“NV” automatically) , The entries for 07:45 and 08:00 are missing.
After every power failure the first load profile is marked as “NV”. In case
the internal buffer for the RTC sustained the meter through the power failure
all further entries are not marked “NV”. Reboot In some instances an internal
meter reboot may ocurr. In these cases the corresponding load profile entry is
marked with “NV”.
46
Display Load Profile
User Manual EMU Professional II
The load profile menu always shows the latest entry on call up. Once all
110’457 entries are full, the EMU Professional II automatically deletes the
oldest entry. The numeration of the load profiles however does not jump back
to 0 but continues as if nothing happened.
Example: Your EMU Professional has already saved 200’000 load profiles. If you
go through the list of load profiles you will start with load profile nr.
200’000. If you go back 105’378 entries you will jump back to load profile nr.
200’000. The data for load profile nr. 194’622 has been overwritten.
The following information is shown on the display:
000006: Index of the shown entry. The first entry has index 1 and the button
“Arrow Down” lets you go through all stored load profiles (chronologically
descending).
01.01.2021 01:30:55: Time stamp of the entry. Current time and date. This is
the time the device had on the internal clock at the time of saving. There is
no internal differentiation of timezones. The time is always in UTC.
NV: Validity flag. The following situations result in a load profile being
marked with “NV”:
, If any of the above mentioned device parameters are adjusted, the load
profile of that time interval is marked with “NV”
, The first entry after the startup of the meter is always marked as “NV”.
This is due to the assumption that the startup happens because of a prior
power fail.
, If a time synchronization does not happen within 2 weeks of the last one,
all entries after these 2 weeks are marked “NV”.
Valid entries do not have any markings.
T1/T2 00000000.0 kWh: Meter reading per tariff. Value of the active energy
register at the time of the entry.
Note: For load profiles according to PTBA 50.7 only a tworate tariff is
available. Tariff changes are set at the start of the next interval.
