2.2.1 Supply voltage
The supply voltage (according to the technical specifications and the instrument type) connects to terminals
AV1 (no. 9) and AV2 (no. 10) via a disconnecting device (switch – see the wiring diagram fig. 16b, fig. 16c). It
must be located at the instrument’s proximity and easily accessible by the operator. The disconnecting device
must be marked as such. A circuit breaker for nominal current of 1 Amp of the required rating makes a suitable
disconnecting device. Its function and working positions must be clearly marked (symbols ’O’ and ’I’ according
to IEC EN 61010-1).
2.2.2 Measured voltage
The measured phase voltages are connected to terminals U1 (no. 12), U2 (no. 13), U3 (no. 14). The common
terminal to connect the neutral wire is identified as N (no. 11; it remains unused with delta and Aron connections).
It is suitable to protect the voltage lines measured for example with 1A fuses of the required rating. Measured
voltages can also be connected via instrument voltage transformers. A connection cable maximum cross section
area is 2.5mm2.
2.2.3 Measured currents
The instruments are designed for indirect current measurement via external CT only. Proper current signal
polarity (k, l terminals) must be observed. You can check the polarity by the sign of phase active powers on the
instrument display (in case of energy transfer direction is known, of course). Terminals I2k, I2l are not used in
case of the Aron connection.
6
X/5A current input option The current signals from 5A or 1A instrument current transformers must be
connected to the terminal pairs I1k, I1l, I2k, I2l, I3k, I3l (No. 1
ö
6). A connection cable maximum cross section
area is 2.5mm2.
X/100mA current input option The supplied current transformers (which are standard accessory) must
be clamped on measured wires and interconnected with corresponding terminal pairs I1k, I1l, I2k, I2l, I3k, I3l
(no. 41
ö
46) using a twisted-pair cable of maximum length of 3 m.
Warning !: Connection of other current to an instrument is strictly forbidden !!! The instru-
ment can be seriously damaged by using unsupported 3rd party CTs!
The secondary winding of the split-core transformers is led to the screw terminals. The ”K“/”L“ and ”k“/”l“
orientation is marked on the CT guide groove. A connection cable maximum cross section area is 1.5mm2.
X/333 mV current input option (333mV CT or RCT only) these instruments are supplied with separate
terminal connector for each current input. The current transformers with nominal output voltage 333 mV must
be clamped on measured wires and interconnected with corresponding terminal pairs using a twisted-pair cable
of maximum length of 3 m. Again, proper current signal polarity (k and l terminals) must be observed.
Connection of the current inputs with X/333mV option is shown in fig. 5: terminals SI1, SI2 and SI3 (nr. 62,
65 and 68) are input signals corresponding to currents I1, I2 and I3 (terminal “k” of the measuring CT or white
wire of the RCT). SG terminals (nr. 63, 66 and 69) are a common pole for signals I1, I2 and I3 (terminal “l”
of the measuring CT or black wire of the RCT) and also a negative pole of the internal 5V auxiliary voltage
supply. These terminals are internally interconnected. SP terminals (nr. 61, 64 and 67) are the positive pole of
the internal 5V auxiliary voltage supply for the connected RCT sensors.
Warning !: Connection of unsupported type of current transformer such as the common type
with 5A or 1A secondary to an 333mV option instrument is strictly forbidden! The instrument
can be seriously damaged!
Warning !: Do not connect the current input signals of the 333mV option with neither ground
nor other potential ! Otherwise, measurement accuracy can be affected or the instrument can be
damaged!
The flexible current sensors with embedded integrator usually require a power supply. For such purpose the
instruments are equipped with auxiliary power supply 5V. Maximum load of each sensor connected is 20 mA.
2.2.4 Communication peripherals
USB communication port for USB slave is located on the front panel in its bottom-right corner. This
communication port is intended for easy local configuration and fast download of archived data to the local
PC. Use the supplied USB cable only. SMY 133 is a USB slave device. For correct operation it needs a driver
installed in your operating system (see the ENVIS user guide for more info).
Ethernet interface (optional) 10Base-T Ethernet interface with RJ-45 connector described ETH is situated
on a back side (terminal panel) of the device. Ethernet interface can be used as substitution for the primary
RS-485 for connection of the device to LAN and for easy connection of remote control PC.
RS-485 Serial Line serves usually as a remote communication for reading of actual data, archive downloading
and device configuration. Serial RS-485 line uses terminals A, B and GND (no. 28, 29 and 30 on fig. 3a and 8).
The final points of the communication line must be properly terminated with resistance.

from an electricity meter or other quantity, as a simple programmable two-position controller or as a remote
application controlled output.
Relay output (R) (SPST-NO: single-pole, single-throw, normally open relay) is used. Maximum allowable
voltage and load current according to the technical specifications must be fulfilled.
Impulse output (I) is accomplished by a semiconductor switching device. It is assumed that the input opto-
couplers of the external recording or control system will be connected to these outputs via proper current–limiting
resistors. The signal polarity is not significant to the device.
10
Digital Input DI1 (optional with RR, RI and II) state is indicated on display and in remote software.
Connect a voltage signal of appropriate magnitude to the the DI1 terminals. The signal polarity is not significant
to the device. If the voltage exceeds declared level, the input is activated and the symbol is displayed. Usual
12 or 24 V DC/AC signals can be connected directly. If you need to connect a voltage signal of magnitude
exceeding maximum digital input voltage, an external limiting resistor of appropriate rating must be used.

2.5 Detailed configuration of SMY 133 on a PC
To begin a measurement it is recommended to configure the SMY 133 instrument appropriately. This setting is
done by PC with an ENVIS.Daq2application.
Warning! This setting will erase all previously archived data in memory of the instrument.
Before writing new configuration to the device make sure to backup the last measured archive.
1. Turn on the instrument. Under normal conditions the unit will boot up and display its predefined initial
screen.
2. Connect the SMY 133 to a computer via USB3, RS-485 or Ethernet interface. Now the unit is ready to
2The ENVIS.Daq application is used for configuration of the instrument. This software is available for download form
WWW.KMB.CZ as a part of ENVIS installation package or as a standalone application. Detailed description can be found in
The ENVIS User Guide.
3If a USB instrument is connected to the PC for the first time it is necessary to install its driver in Windows. You can find
the actual driver for our instruments online on the the WWW.KMB.CZ website. It is also located in the driver folder of ENVIS
software installation folder, for example in: ’C:\Program Files (x86)\KMB systems\ENVIS 1.2\driver’

button Receive user can re-read the stored configuration from a device. This will effectively cancel all the local
modification in the application. Unwritten changes in configuration on each tab is signalized by an exclamation
sign. Buttons Save and Load provide a possibility to archive the actual settings to a file.
For correct operation an appropriate configuration of at least Installation and Time and Date tab is crucial.
2.5.1 Installation (fig.16)
Nominal Frequency - defines the nominal network frequency measured at 50 or 60 Hz. It also influences,
how power quality indice are evaluated.
Connection Mode - the way of connection of the instrument to the measured voltage — either direct voltage
measurement or via voltage transformers (usually in a HV network).
Connection Type - type of measured network according to the actual connection - three-phase star, three-
phase delta or Aron connection. Supported connections schema are in fig. 16b and 16c for illustration.
UNOM ,PN OM (rated voltage and power) — correct configuration of these values influences relative values
used on display and in condition evaluation (alarms, PQ evaluation, IO, ENVIS data processing).
–UNOM is a nominal (primary) voltage of the measured network
–PNOM is a nominal power given by the system transformer or used protection device.
VT Ratio, VTN Ratio - sets the conversion ratio of voltage inputs for Connection Mode: via VT measure-
ment. Must be set accordingly to the primary and secondary rating of the measuring voltage transformer
(transfer ratio). ’VTN’ designates the optional fourth voltage input, available with some Connection Types.
–nominal primary voltage: default value for ’via VT’ option is 22 000 V.
–nominal secondary voltage: default value is 100 V (other common values are 110, 120, 230V)
CT Ratio, CTN Ratio - sets the conversion ratio of current input. ’CTN’ designates the fourth input,
usually a neutral wire.
–For standard instruments with X/5A and X/1A is specified as a ratio between primary and secondary
current. Default value is 100 A/5A resp. 1 A.
–For SMY 133 options X/100mA and X/20mA a nominal primary and nominal secondary current of
the supplied transformer is used. Default value is 100 A/100 mA resp. 20 mA.
–
Multiplier U : this parameter is usually not necessary. Default value is 1. In special cases it can be used to
correct the ratio of measured voltage.
Multiplier I - this parameter is usually not nescessry. Default value is 1.
–in case of direct current measurement (fig. 4) leave the Multiplier I in its default value:1.
–in case of indirect current measurements with nonstandard conversion ratio (multiple loops of mea-
sured wire through the measuring transformer etc) specify the new ratio as a fraction5to which you
need to multiply the original conversion ratio to get the real measured value of current.
5If, for example, primary CT with ratio 100/5 is used, set multiplier to 100
5= 20. Another example, when Multiplier I can
be used, is winding more than one loop of measured conductor through current transformer for sensitivity extension (and range
reduction). For example for 4 loops Multiplier I should be set to 1
4= 0.25.
