5. Settings
Introduction
Instrument settings c an be remotely modified w ith communication (RS485 or USB) and M-Set
software when connected to a PC.
M-Set software
M-Set is a software tool for complete monitoring of measuring instruments, connected to a PC via
serial or USB communication. A user-friendly interface consists of four segments: device
management, instrument settings, real-time measurements and software upgrading.
Device management
Select the instrument in a favourite’s line. Use the network explorer to set and explore the device’s
network. Communic ation parameters of all dev ices and their addresses in the network c an be
easily set.
Instrument settings
Multi register edit technology assures a simple modification of settings that are organised in a tree
structure. Besides transf erring settings into t he instrum ent, storing and reading f rom the setting
files are also available.
Real-time measurements
All supported meas ur ements can be captured in r ea l t ime in a table form. For further processi ng
of the results of measurements, copying via a clipboard into standard Windows formats is
supported.
Software upgrading
Always use the latest version of software, both M-Set and software in the instrument. The
programme autom atically informs you on available upgrades that can be transf erred from the
website and used for upgrading.
More information about the M-Set software can be found in the M-Set help
system.

M-Set user interface
Setting procedure
In order to modify instrument settings with M-Set, current parameters must be loaded first.
Instrument settings c an be acquire d via a comm unication link (ser ial or USB) or c an be loaded
off-line from a file on a local disk. Settings are displayed in the M-Set setting window - the left part
displays a hierarchica l tree structur e of settings, the r ight part displa ys parameter values of the
chosen setting group.
General settings
General settings are es sen tial for the tr ansducer . T hey ar e di vided int o four addit ional s uble vels
(Connection, Communication, Display and Security).
Description and location
Two parameters that are intended for easier recognition of a certain unit. They are especially used
for identification of the device or location on which measurements are performed.
Average interval
The averaging interv al def ines t he ref res h rate of m easur em ents on com m unication and r em ote
display.
Temperature unit
Choose a unit for temperature display.
Maximum demand calculation (MD mode)
The instrument provides maximum demand values using therm al function. A thermal function
assures exponent thermal characteristic based on simulation of bimetal meters. Maximum values
and time of their oc cur r ence ar e s tored in the device. A t ime constant (t. c.) c a n b e s et from 1 to
255 minutes and is 6 times the thermal time constant (t. c. = 6 * thermal time constant).
You can download freeware M-Set from www.deif.com.

DEIF A/S Page 17 of 51
Example:
Mode: thermal function
Time constant: 8 min.
Current MD and maximal MD: reset at 0 min.
Starting current for PF and PA (mA)
At all measuring inputs , noise is usually presen t. I t is c ons tant , and its influence o n the ac cur acy
is increased by decreasin g measuring signals. It is pre s ent als o when measuring signals are not
connected, and it oc curs at all f urther calc ulat ions as v ery sp oradic m easurem ents. B y settin g a
common starting cur rent, a limit of input signal is d efined where measurements and all other
calculations are still performed.
Starting current for all powers (mA)
Noise is limited with a starting current also at measurements and calculations of powers.
Minimum synchronisation voltage
If all phase voltages ar e smaller than this (nois e l imit) setting, the instrument uses current in puts
for synchronisation. If also all phas e curr ents are s maller t han Starting current for PF and PA
setting, synchronisation is not possible and frequency displayed is 0.
Reactive power and energy calculation
Two different principles of reactive power and energy calculation are used:
Standard method:
With this method, a r eactive power and energy is calculated, based on the ass umption that al l
power (energy), which is not active, is reactive.
Q
2
= S2 – P2
This also means that all higher harmonics will be measured as reactive power (energy).
Delayed current method:
With this method, reacti ve po wer (ener gy) is c alculate d b y multipl ication of volta ge samples and
delayed current samples (see chapter 8, “Ap pen dix B: Calc u lat ions and equations” on page 36):
Q = U × I|
+90°
With this method, reactive power (energy) only represents the true reactive component of
apparent power (energy).

When connection is selected, load connection and the supported measurements are defined (see
chapter 6, “Measurements” regarding connection mode, on page 23).
Setting of current and voltage ratios
Before setting current and voltage ratios, it is necessary to be familiar with the conditions in which
the device is t o be used. All other measurements and calcul ati ons d epe nd o n these settings. Up
to five decimal places can be set.

Used voltage and current range
Setting of the rang e is connected with all settings of alarms, analogue outputs and a display
(calculation) of energy and measurements recording, where 100% represents 500 V 5 A. In case
of subsequent change of the range, alarms settings must be correspondingly changed, as well.
Nominal frequency
A valid frequency measur ement is within the r ange of nom inal frequenc y ±32 H z. This setting is
used for alarms.
Energy flow direction
This setting allo ws m anual c hange of ener g y flow d irec tion (I MPORT to EX PORT or vice versa)
in the readings tab. It has no influence on readings sent by communication.
CT connection
If this setting is set to REVERSED, it has the same influence as if CTs would be reversely
connected. All power readings will also change their sign.
Communication
Serial Communication
Define parameters that are important for the operation in the RS485 network. Factory settings of
communication are #3 3\115200,n,8,2 (address 1 to 247\baud rate 2400 to 115200 b/s, parity,
data bits, stop bit).
Modbus table: with this setting, a Modbus table for measurements and settings is defined. Modbus
addresses for measurements and settings can be compatible with the previous family of
transducers (MTR-2). For a more detailed description, see chapter 7, “Appendix A: Modbus
protocol”, on page 28.
USB Communication
For description of a ll settings see Serial Commun ication, appendix A. For driver inst allation,
see the note on page 13. The instrum ent will establish a USB connection with the PC approx. 5
seconds after physical connection to the USB port.
Settings of connections must reflect actual state, otherwise measurements are
not valid.

Security
Parameter settings are divided int o three groups regarding security level:
1. At the firs t level ( PL1), sett ings of a real t im e clock c an be cha ng ed, an d energy meters
and MD can be reset.
2. At the second l evel (PL2), the access to all d ata that are protected with t he first level
(PL1) and setting of all other parameters in the »SETTINGS« menu is available.
3. A backup password (B P) is used if pas swords at levels 1 (PL1) and 2 (PL2) have been
forgotten, and it is different for each device (depending on a serial number of the meter).
The BP password is available in the support department at DEIF, and is entered instead
of the password PL1 or/an d PL2. Do not forget to sta te the meter serial number when
contacting the personnel at DEIF.
User information
Password setting
A password consists of four letters taken from the British alphabet from A to Z. When setting a
password, only the letter being set is visible while the others are covered with *.
Two passwords (PL1, PL2) and the time of automatic activation could be set.
Password modification
A password can be modified; however, only that password can be modified to which the access
is unlocked at the moment.
Password disabling
A password is disabled by setting the "AAAA" password.
Energy
Active tariff
When active tariff is set, one of the tariffs (up to four) is defined as active.
Common energy exponent
Common energy expon ent def ines minimal energy that c an be displayed on the energ y c oun ter .
On the basis of this and a counter divider, a basic calculation prefix for energy is defined (−3 is
10
−3
Wh = mW h, 4 is 104Wh = 10 kW h). A com m on energy expo nent als o inf luenc es in sett ing a
number of impulses for energy of pulse output or alarm output functioning as an energy meter.
Define the common energy exponent as recommended in the table below, where counter divider
is value 10 as default. Values of primary voltage and current determine a proper common energy
exponent.
A serial number of devic e is stated on the lab el and also acc essible wit h the M-
Set software.
A factory-set password is “AAAA” at both access levels (L1 and L2). This
password does not limit access.
After modification of energy parameters, the energy meters must be reset.
Otherwise, all further energy measurements could be incorrect.

Average interval for analogue output
Defines the average interval for measurements on the analogue output. Avail able settings are
from 1 period (0.02 sec by 50 Hz) up to 128 periods (2.56 sec by 50 Hz).
Fast analogue output
Functionality of the fast analogue output module is the same as with the standard analogue output
module.
The only difference is its faster response time (≤ 50 ms), and consequential higher ripple. For a
proper behaviour of the fast analogue output module (f ast response), the average inter val must
be set to minimum (1 period).
Relay output module
Relay output module can be assigned different functions.
− Alarm notification functionality (alarm output)
− Pulse output for energy measurement (pulse output)
− General purpose digital output (digital output)

Pulse output functionality
A corresponding energy counter (up to 4) can be assigned to a pulse output. A number of pulses
per energy unit, pulse length, and a tariff in which output is active are set.
Calculation of recommended pulse parameters
Number of pulses per energy unit s hould be in cer tain lim its acc ording to expec ted po wer. If not
so, the measurement from pulse output can be incorrect. Settings of current and voltage
transformers can help in estimation of expected power.

Alarm notification functionality
An alarm notificatio n function ca n also be as signed to out put. In cas e of an y alarm occ urrence,
alarm output will trigger passive electromechanical relay or passive solid-state relay.
Two parameters should be defined for each alarm output:
− The source for assigned alarm (alarm group 1, 2 or both)
− Type of output signal when alarm is detected.
General purpose digital output
This functionality allows user to enable/disable output relay by software settings (when
appropriate values are set in Modbus table).

Alarms
Alarms are used for alarming exceeded set values of the measured quantities.
Alarms setting
MTR-3 supports recording and storage of 16 alarm s in two groups. For each grou p of alarms , a
time constant of maximal values in thermal mode, a delay time and alarm deactivation hysteresis
can be defined.
Quantity, value (a current value or a MD – thermal function) are defined for every individual alarm.
Reset operations
Reset energy counters (E1, E2, E3, E4)
All or individual energy meters are reset.
Reset MD values
Current and stored MDs are reset.
Reset the last MD period
Current MD value is reset.
Reset alarm output
All alarms are reset.
New values of alarms a re calculated in percentage at the modification of the
connection settings. If used voltage, current range is changed, the limit values
of alarms will change proportionally.

For 3b and 3u connection modes, only phase-to-phase voltages are measured.
Because of that, factor √3 i s applied to calculation of quality consi dering nominal
phase voltage.
For 4u connection mode, measurement support is the same as for 1b.

Explanation of basic concepts
Sample factor − MV
A meter measures al l primary quantities with sample frequenc y which cannot exc eed a certain
number of samples i n a time p eriod. Based o n these li mitations (65 Hz·128 sam ples) a sam ple
factor is calculated. A sample factor (M
V
), depending on frequency of a measured signal, defines
a number of periods for a measurement calculation a nd th us a n umber of harmonics c onsid er ed
in THD calculations.
Average interval − M
P
Due to readability of m easurem ents from c ommunication, an average interval ( M
P
) is calculate d
with regard to the measur ed signal frequency. The average interval (see “A verage interval” on
page 16) defines the refresh rate of displayed measurements based on a sampling factor.
Power and energy flow
The figure below shows a flow of active power, reactive power and energy for 4u connection.
Calculation and display of measurements
This chapter deals with capture, calculation and display of all supported quantities of
measurement. Only the most important equations are described; however, all of them are shown
in chapter 8, “Appendix B: Calc ulations and equations” on page 36 with additional descr iptions
and explanations.
The power and energ y flow is defined as standard from a generator’s point of
view. This means t hat a consumer using energy will be exporting power. It is
possible to change export/impor t definition via the M-Set, by changing the energy
flow direction.
Calculation and display of measurements depend on the used connection. For
more detailed information, see “Survey of supported measurements regarding
connection mode” on page 23.

Present values
All values are calculated as an average of number of periods set in general sett ings/average
interval.
Voltage
The instrument meas ures true RMS values of all phas e voltag es (U 1, U2, U3), c onnect ed to the
transducer. Phase-to-phas e v olt ages ( U12, U 2 3, U 31), average phase volt age ( U f) and average
phase-to-phase voltage (Ua) are calculated from measured phase voltages (U1, U2, U3).

Active, reactive and apparent power
Active power is calculated from instantaneous phase voltages and currents.
Two different principles of reactive power calculation are used:
Standard method:
With this method, a reactive power is calculated based on the assumption that all power which is
not active is reactive.
Q
2
= S2 – P2
This also means that all higher harmonics will be measured as reactive power.
Delayed current method:
With this method, reacti ve po wer (ener gy) is calcul ated b y multipl ication of volta ge s am ples and
delayed current samples (see chapter 8, “Ap pen dix B: C alcu lat ions a nd equations” on page 36:
Q = U × I|
+90°
With this method, reactive power (energy) only represents the true reactive component of
apparent power (energy).
All measurements are s een vi a communication. For m ore det ai led inf or mation about calculation,
see chapter 8, “Appendix B: Calculations and equations” on page 36.

Power factor and power angle
Power factor is calculat ed as quotient of acti ve and apparent power for each phase separ ately
(cosϕ
1
, cosϕ2, cosϕ3) and total power angle (cosϕt). For correct display of PF via analogue output
and application of the alar m, ePF (extended power factor ) is applied. It illustrates po wer factor
with one value as described in the table below. For a display on the remote display, both of them
have an equal display function: between −1 and −1 with the icon for inductive or capacitive load.

Example of analogue output for PF and ePF:
The power angle represent s the angle between the first voltage harm onic and the first current
harmonic for each ind ivid ua l ph as e. T he t ot al p o wer a n gle is c alcu late d from the total act ive a nd
reactive power (see equati ons for total power ang le, in chapter 8, “Append ix B: Calcu lat ions an d
equations on page 36). A positive sign shows inductive load, and a negative sign shows capacitive
load.
Frequency
Network frequency is calculated from time periods of measured voltage. Frequency is an average
of number of periods set in general settings/average interval.
Energy
The energy of each of four energy counters is available.
MD values
Measurements of MD values.
THD − Total Harmonic Distortion
THD is calculated for phas e currents, phase and ph ase-to-phase vol tages and is expres sed as
percent of high harmonic components regarding RMS value or relative to first harmonic.
The instrument uses a measuring technique of true RMS values that assures exact
measurements with the presence of high harmonics up to 31st harmonic.

7. Appendix A: Modbus protocol
Modbus communication protocol
Modbus is enabled via RS485 or USB. The response is the same type as the request.
Two versions of Modbus register tables are available:
• VERSION 1: MTR-3 Modbus registers
• VERSION 2: Compatibilit y with previous version of the product, the MTR-2
Modbus
Modbus protocol enables operation of device on Modbus networks. For device with serial
communication, the Modbus protocol enables point-to-point (for example device to PC) multi-drop
communication via RS485 communication. Modbus protocol is a widely supported open
interconnect originally designed by Modicon.
The memory reference for input and holding registers is 300001 and 400001 respectively.
The register tables no the next pages shows both the PLC address and Modbus address to read
from the desired register.
Example for reading Frequency parameter:
PLC: Read address 300106-300107
Modbus: Read address 105-106 with function 4
The Modbus address will always be 1 lower than the PLC address because PLC addresses starts
with 1 where Modbus addresses starts with 0.
