SMV / SMP / SMVQ / SMPQ
2. Brief Description
This chapter provides a brief description of connection and basic operation of the instruments in a
typical installation. A detailed instrument description of all its features and connection possibilities
follows.
2.1 Instrument Connection
The instruments of the SMV / SMP / SMVQ / SMPQ series belong to equipment class I, therefore it is
absolutely necessary to connect the PE protective conductor to the PE terminal of the
instrument ! The recommended cross section of the protective conductor is 2,5 ÷ 4,0 mm2, loop with
diameter of 4,3 mm ( M4 terminal ).
It is necessary to connect an auxiliary supply voltage in the range as declared in technical
specifications table to the terminals AV1 ( L ) and AV2 ( N ). In case of DC supply voltage the polarity
of connection is generally free, but for maximum electromagnetic compatibility the grounded pole
should be connected to the terminal AV2.
The supply voltage must be connected via a disconnecting device ( switch - see installation diagram ).
It must be situated directly at the instrument and must be easily accessible by the operator. The
disconnecting device must be labelled as the disconnecting device of the equipment. A circuit breaker
at the nominal value of 1A may be used for the disconnecting device; however its function and
position must be clearly marked (symbols „O" and „I" according to EN 61010 - 1).
Fig. 2.1: T pical star (4Y) connection, mains 3 x 230/400 V
Measured phase-to-neutral voltages and neutral voltage (measured towards to the PE ) connect to
terminals VOLTAGE / N, U1, U2 and U3. Measured voltages must be protected, e.g. by 1A fuse.
Current signals from the current transformers at the nominal value of 5 or 1 A AC must be connected
to a pair of terminals CURRENT / I1k, I1l, I2k, I2l, I3k, I3l, or INk, INl. It is necessary to observe their
polarity (terminals k, l). Examples of other connections are mentioned below in the manual.
The maximum cross section of the conductors to the terminal panels is 2,5 mm2.

SMV / SMP / SMVQ / SMPQ
2.2 SMV / SMVQ Instrument Setup
When switching on the power supply, the instrument will perform a display test and then will display
the code „ Init", firmware release number and a group of measured values, e.g. phase voltages U1, U2,
U3 (or UN). The information is shown on the display as follows, for example:
In this case the LED- diode VLN indicates the type of displayed quantities, i.e. phase voltages. The
instantaneous measured values in phases L1, L2 and L3 can be viewed in the first three rows. In the
fourth row the value of voltage UN is displayed.
To display the real values of voltages, currents and other quantities, the instrument must be preset.
Setup of the instrument is stated by specifications, such as for example the type of measured voltage
[direct measuring or via metering voltage transformers (VT) and their conversions], the method of
voltage and current connection (star, delta, Aron ), or the conversion metering current transformers
(CT) etc. The summary of the basic parameters is stated in the table below.
Generally, besides nominal frequency ( fNOM , parameter P.03/3) it is only necessary to adjust the CT
conversion. Assuming that the conversion of used CT for inputs of current L1 to L3 is 750/5 A. To edit
the parameters, enter by pressing and holding the ► button (about 6 s). The display will show the
parameter P.00 (=lock). Another (short) touch of the ► button will switch to the group of parameters
P.01, with conversions of the current transformers. A flashing specification in the 2nd row designates
the actual selected parameter, which is the nominal secondary current of the CT. To keep the value of
5A, press ► and switch over to the next parameter in the third row. For example value 500 will start
flashing, which is the preset nominal primary current of the CT. This value can be gradually increased
by touches of the ▲button to 750 A.
Finally, to finish editing the parameters, press and hold the ► button again for about 6 sec. and the
instrument will get back to the display of measured values.

2.2.1 Locking and Unlocking of the Instrument
The instruments are supplied in an „unlocked" state (parameter P.00 = 0), that means the basic
parameters can be randomly edited, following the procedure mentioned above. After putting it into
operation, the parameters editing can be „locked" and the instrument can be protected from possible
9

SMV / SMP / SMVQ / SMPQ
unqualified manipulation, by simply switching the parameter P.00 to the position 1(=locked).
Unlocking the instrument requires this particular procedure: following the above - mentioned method,
switch the instrument into the parameters display and by pressing the ▲ and ▼buttons find the
parameter P.00 – value 1 in the second row indicates the locked instrument. At the same time press
the ▲and ▼buttons - randomly selected number will appear in the third row. If it is odd, press ▲ and
if even, press ▼. Repeat this procedure until the parameter value in the 2nd row switches to the value
0, i.e. the „unlock" status. After that, any parameter can be found and adjusted.
2.3 SMV / SMVQ Instrument Operation
After activation of supply voltage, the instrument accomplishes internal diagnostics, updating of
internal database of measured data and then it starts to measure and display the instantaneous
measured values ( inst. ).
The row of LED-diodes on the left side indicate the type of displayed quantities - their summary is
stated in the chart below. The LED diodes k and M determine a multiplier (k=kilo, M=mega, kM=giga)
separately for specifications in rows 1÷3 and extra for row 4 (e.g. when displaying voltage, the diode k
indicates, that the specifications are in kV etc.).
Particular measured quantities can be changed over by using the ▲and ▼buttons. The buttons
►and ◄ can switch the type of displayed quantity: instant (inst.), average (avg.), maximum of
average (max.) or minimum of average (min.), except the quantities THD,harm and EN – these only
show instantaneous values.
Values avg. are evaluated with method and the time window according to parameters P.05 ( for U/I-
group ), P.06 ( for P/Q/S-group ), and P.07 (for PavgE of electricity meter group). Values max./min. are
maximum/mimimum values of the avg.-values reached since last clearing. You can check date & time
of last clearing of each group by listing to window time, which is indicated as Clrt in the 4th row. To
clear max./min. registered values of appropriate group manually, while in the appropriate Clrt -time
window press the ►and ◄ simultaneously and the date/time value starts flashing. Then confirm
clearing with the button ▼( pressing of different button will not clear anything ). Depending on the
listed average values group, only either U/I-group or P/Q/S-group average max/mins or PavgmaxE of
electricity meter group are cleared. If the instrument is locked, clearing is not possible.
In addition, the buttons ►and ◄ can display conditions of the
internal time circuit ( local time ) and immediate conditions of digital
inputs/outputs and so-called error code ( I/O,Err ).
At the I/O,Err.-window actual status of a digital input ( 1st row ) and
two digital outputs (2nd and 3rd row) are displayed. Active state
(closed) is indicated as “1”, inactive (open) as “0”.
At the 4th row the instrument error code is displayed. The E-00 code
means no errors. Other codes can indicate some instrument's
hardware problem – in such case contact the service organization.
The last two LEDs are alarm LEDs A1 and A2. Their function is programmable in the same way as
digital outputs.

•THD, harm : harmonic distortion (THD) and sizes of individual harmonic components of phase
voltages and currents. The evaluation is executed internally up to the 50th order, but the harmonics
up to 40th order only are displayed. The data is in percentage, except current harmonic data directly
in amperes. The order will display for 1sec after the selection by ►and ◄.
•En1p : Single-phase electrical energy. It is evaluated in four quadrants, i.e. separately - consumption
and supply of active energy and inductive and capacitive component of reactive energy. The data
are summary for all the tariff zones. The reset date & time are stated in the last window.
•En3p : Three - phase electrical energy. Again, it is evaluated in four quadrants, and in addition in
three preset tariff zones including a summary for all the zones ( setup of the tariff zones can be
implemented only by using connection with PC and control program ENVIS). Data displayed to 12
places across rows 1 ÷ 3. The last window again shows the reset date & time ( this specification is
equivalent to corresponding specification of En1p ). The energy counter reset ( common to En1p
and En3p ) is executed when „time" is displayed, by simultaneously pressing ►and ◄ and the
confirmation button ▼- pressing different buttons will not reset the counters. If the instrument is
locked, resetting is not possible.
•PavgE : active power demands ( = average active powers ) of “electricity meter group” (evaluated
independently of standard average values) , single-phase and three-phase values. The
instantaneous value (inst.) evaluated as the average with preset method and over preset period
( parameters P.07 ). The maximum achieved values of these power demands can be displayed in
the window „max." and occurrence date & time of the three-phase power demand in the third window
„max" „time". The last window shows the date & time of resetting the maximim value PavgmaxE
( window „time" with a Clrt indication in the 4th row ). The PavgmaxE can be reset manually in the way
already described above.
•Hz, a.i. : the mains frequency ( 2nd row ) is evaluated, if the voltage is present at least on one phase.
If the voltage is not connected or the frequency is out of measurable range, the diode flashes.
In the 4th row, analog input value is displayed. Either 20mA curent loop input value (recalculated to
preset range) or Pt100 temperature sensor input in °C.
Resolution of values displayed can be set to 3 or 4 significant figures ( parameter P.04 / 3 ). In case of
4 negative polarity is indicated by a flashing decimal point of the data.

2.4 SMP / SMPQ Instrument Setup
When switching on the power supply, the instrument will display manufacturer's logo for approx. 0.5
sec and after that usually a group of actual measured values, e.g. phase voltages U1, U2, U3 (or UN), is
displayed. The information is shown on the display as follows, for example:
Quantities' names, i.e. U1, U2 and U3 indicates that actual phase voltages in phases L1, L2 and L3 are
displayed.
To display the real values of voltages, currents and other quantities, the instrument must be preset.
Setup of the instrument is stated by specifications, such as for example type of measured voltage
[direct measuring or via metering voltage transformers (VT) and their ratios], method of voltage and
current connection (star, delta, Aron ), or metering current transformers's (CT) ratios etc.
Besides nominal frequency ( fNOM ), usually it is only necessary to adjust the CT conversion. Assuming
that the conversion of used CT for inputs of current L1 to L3 is 750/5 A. To edit the parameters, press
the MENU button, navigate to the Menu-Setting with the buttons ►and ◄ and then choose it with
the button. In the Setting window choose Setting-Installation option. The Setting-Installation
window appears :
In the window navigate down to the current transformer ratio parameter of inputs I1÷ I3 ( CT ) and
choose with the button.
Now you can type new value of the parameter : with the ►button you can move from a digit to
another one and to set each digit to target value using the ▲and ▼buttons. At the end press the
button and the parameter is set. You can set nominal frequency fNOM and other parameters in the
same way.
Finally, when escaping the window you must confirm new setting by pressing the button and all of
the parameters of the window are stored into the instrument's memory.
The instrument includes a row of other parameters – their description is stated in following chapters.

2.4.1 The Instrument Lock
Three levels of locking to allow protection against unauthorized access are implemented. The active
protection level is symbolized in the main menu by three different states of the Lock icon :
●Unlocked – anyone with physical access to the instrument can freely set-up and
configure all parameters in the instrument, clear archives and other persistent data
or reset counters. In this state anyone can also lock the instrument.
●User Locked – fixed user password (PIN) is required if the instrument
configuration is changed or there is a request to clear any of the data.
●Admin Locked – user defined admin password (PIN) is required if the instrument
configuration is changed or there is a request to clear any of the data.
2.4.1.1 Locking
If the instrument is unlocked, you can lock it to either user or admin mode.
To lock the instrument into the user locked mode, simply switch in the Menu-Lock window the lock
from  to . Then escape from the window with the  button and confirm saving of changed state.
To lock the instrument into the admin locked state, press the buttons  and ▼ simultaneously in the
Menu -> Lock window. Then normally hidden admin password option
appears. Choose it and type the new admin password code – the value
must be different from 0000. Then escape from the Menu-Lock window
with the  button and confirm saving of changed state. The admin
locked state is indicated with the “A”-character inside the lock icon.
Warning ! Store the admin password code at the secure place to be
able to unlock the instrument later in case the code is forgotten !
2.4.1.2 nlocking from the ser Locked State
To unlock the instrument, switch in Menu -> Lock the lock state back from  to  by entering
user password. The value of this password is fixed and equal to the last four digits of the serial
number of the instrument. This serial number can be found in device display under Menu -> Info ->
Serial number .
Then escape from the Lock window with the  button and confirm saving of changed state.
2.4.1.3 nlocking from the Admin Locked State
To unlock the instrument, switch in Menu -> Lock the lock state back from  to  by entering
correct admin password. Then escape from the Menu-Lock window with the  button and confirm
saving of changed state.
Note, that such unlocking is temporary and the instrument will switch to the admin locked state
automatically approx. 15 minutes after last pressing of any button. To avoid this you need to set the
admin password code to value 0000 ( in the same way as the locking as described above ). Only after
that the instrument state changes to permanently unlocked state.
Note : In case the admin password is lost, visits manufacturer's website at www.kmbsystems.eu and
follow instructions to obtain the alternate unlock code.
2.5 SMP / SMPQ Instrument Operation
After an activation of supply voltage, the instrument accomplishes internal diagnostics, updating of
internal database of measured data and then it starts to measure and display actual measured data.
Navigation through all measured data is intuitive with arrow keys. Layout of screens can be found at
following figure.
Two alarm LEDs A1 and A2 function is programmable in the same way as digital outputs.

3. Detailed Description
3.1 Basic Characteristics
The instruments represent combined performance measuring and monitoring device for continuous
evaluation of electrical qualities, complying to power quality measurement methods as defined in IEC
61000-4-30 ed.2 class S requirements. They has been designed to monitor and record line-to-line and
phase voltages, currents, active, reactive and apparent powers, power factors, THD voltages and
currents, harmonic components of voltages and currents, active and reactive energy, average power
maximums, frequency and other electrical quantities in low voltage, high voltage and very high voltage
power grids. Furthermore, it also allows measuring one external quantity via its current loop input or
one temperature with external Pt100 sensor.
For special measurement purposes, the instruments can be equipped with additional firmware
modules : the voltage event module (VE), the ripple control signal measurement module (RCS) and
the general oscillogram recording module (GO).
The SMV/SMP instruments are equipped with the VE module as default. With this module, voltage
sags, swells and interruptions can be detected and registered. Furthermore, the instruments also
evaluate voltage quality according to the EN 50160 standard, measure flicker severity indexes and
inter-harmonic distortion.
The instruments are fitted with inputs for the connection of three voltage signals, a neutral voltage
signal, three fully isolated current inputs ( for use with external CTs ) as standard and additional
neutral wire current input at appropriate models. That allows measuring in five-conductor power
systems (current measurement by middle conductor – „operating zero" and its voltage against PE) –
system TT and TN-S, TN-C-S. Measurement at isolated networks ( IT ) is possible too ( neutral wire
input unconnected ).
Besides standard "X/5A“-option models, which are designed for connection of CTs with 5 AAC or 1 AAC
nominal secondary current, "F“-option models for use with the B3000/1000 Rogowski principle based
flexible current sensors and "S"- or "P"- option models for the miniature JC-line split core current
transformers or, respectively, the JP-line through-hole current transformers are available.
The power supply must be secured by a separate voltage (AC or DC). “L”-option models are designed
for 24 or 48 VDC nominal voltage auxiliary power supplies.
Continuous (gap-less) measuring is applied and true root-mean-square values ( TRMS ) of voltages
and currents are calculated. Furthermore, actual powers, power factors ( PF, λ ) and powers/power
factors of fundamental harmonic components ( cos φ ) are evaluated. The measurement of the level of
the total harmonic distortion ( THD ) of voltages and currents as well as particular harmonic
components is executed up to the 63rd order.
The instruments comprise three-rate tariff four-quadrant electricity meter with maximum average
active power ( maximum demand ) registration. All results for actual month, last month and total sum
since reset are stored in the device. A separate archive dedicated for automated meter readings can
record actual status in preselected intervals.
Except of the main record archive another archives are implemented to store information of occurring
voltage swells, dips and interruptions, archive power quality evaluations and log internal operational
journals of the instrument.
Measured data are saved in high capacity „Flash" type memory. For the time identification of
recorded data, a battery backuped real-time circuit (RTC) is used. The RTC can be synchronized with
either logical input or a remote communication link.
16

SMV / SMP / SMVQ / SMPQ
The front panel of the instrument has a local USB 2.0 communication link. A portable PC and ENVIS
program supplied as standard can, via this link, adjust the instrument and transfer recorded data. In
addition to the instrument adjustment, ENVIS program allows you to display, view and archive the
measured courses in the graphic form, as well as a number of other features.
For remote communication wide range of interfaces is optionally available. As of protocol the
instrument supports fully documented proprietary KMB message format (accompanied with free
ENVIS configuration/DAQ/archiving software). For integration with existing infrastructure the device
also supports MODBUS RTU and MODBUS TCP protocols.
Basic specifications of the instrument can be set up by using the inbuilt keyboard and the display.
Therefore the instrument can be used as a multifunction panel-mounting measuring instrument without
computer application.
Optionally, the instrument can be equipped with digital input and outputs and an analog input. The
digital input can be used for time synchronization, tariff selection or for status monitoring. The outputs
can be relay or pulse. The behaviour of relay outputs can be programmed according to the measured
values. The pulse outputs are used for transmission of active or reactive power (SO, transmitting
electricity meter). The analog input can be either 20 mA current loop type or Pt100 temperature sensor
type.
