1. APPLICATION
The Multi-transducer is a programmable digital instrument destined for
the measurement and parameter conversion of 3 or 4-wire three-phase
power networks, in balanced and unbalanced systems.
It ensures the measurement and conversion of measured values into
standard analog current signals. Relay outputs signal the overow of
selected quantities, and the pulse output can be used for the consump-
tion monitoring of the 3-phase active energy.

2. TRANSDUCER SET
The set of the transducer is composed of:
-The Multi-transducer 1 pc
- user’s manual 1 pc
- CD disc 1 pc
When unpacking the transducer, please check whether the type
and execution code on the data plate correspond to the order.
The transducer possesses an archive, in which 9000 last mean power
values, with time marker, suitably synchronized with the clock (15, 30
or 60 minutes) are stored.
Maximal and minimal values are measured for all quantities. Additional-
ly, there is the possibility to accommodate the transducer to external
measuring transducers. The transducer has a detection and signaling
of incorrect phase sequence. The actualization time of all accessible
quantities does not exceed 1 second. All quantities and conguration
parameters are accessible through the RS-485 interface and the USB
interface.
Transducer output signals are galvanically isolated from the input
signals and the supply.
.
3. BASIC REQUIREMENTS AND
OPERATIONAL SAFETY
In the safety service scope, the transducer meets to
requirements of the EN 61010-1 standard.
Observations Concerning the Operational Safety:
All operations concerning transport, installation, and
commissioning as well as m aintenanc e,
must be carried o ut by
qualied, skilled personnel, and national regulations for the
prevention of accidents must be observed.

4. INSTALLATION
4.1. Fitting
The transducer can be mounted either on top-hat rail or directly on to a wall
by mounting plate.The overall drawing and the tting way are presented
Fig.1 Overall Dimensions and Transducer Fitting Way.
Before switching the transducer on, one must check the
correctness of connections to the network.
The removal of the transducer housing during the guarantee
contract period may cause its cancellation.
The transducer is destined to be installed and used in
industrial electromagnetic environment conditions.
One must remember that in the building installation, a switch or a
circuit-breaker should be installed. This switch should be located
near the device, easy accessible by the operator, and suitably
marked.

5.2 Messages after Switching the Supply on
After switching the supply
on,
the state diode
should light up for a moment
in red, and next should light up in green. The recording conrmation in
registers is signaled by a short extinction of the state diode.
The incorrect work is signaled by the state diode in the way described
in the chapter 7. The data reception
through the RS-485 interface is
signaled by a pulsing of the Rx diode and the data transmission is

signaled by a pulsing of the Tx diode.
The switching of the relay 1 - 4 on causes the lighting of the AL1 - AL4
diode (g. 4).
5.3 Installation of COM Port Controllers in the Computer
Before conguring the transducer, the driver on the CD should be in-
stalled. The transducer makes use of the software, which creates
in the system, a device of Universal Serial Bus – Multi-transducer
and
connected to it, the virtual COM port named Multi-transducer.
The controller installation in the Windows system causes the addition of
a successive serial COM port to the list of ports serviced by the operat-
ing system.
After connecting the transducer to the USB port, the operating system
informs about the appearance of a new device by means of the message
presented on the g. 5.
The creator to nd a new hardware of the Universal Serial Bus will be
started automatically. One must act in compliance with the creator sug-
gestions, choosing the installation from the indicated location and giving
the path to controllers being in the added CD. Controllers are compatible
with following systems: Windows 2000, XP, Server 2003, Vista, server
2008, (x86 and X64). When installing controllers, information about the
lack of the controller digital signature can occur. One must ignore this
information and carry on the installation.

After the successful ending of the installation, the system will inform
about the installation of a new device (g. 7.). Two new devices ap-
pear in the device manager –
Multi-transducer and Port COM named:
Multi-transducer , acc. to the g. 8.
Fig. 7. Systeme message ending the installation of Multi-transducer
After closing the creator, the system detect immediately the succes-
sive device – USB Serial Port (g. 6.). The creator for detection a new
hardware will start again.

5.4 Transducer Conguration by Means of the
eCon Software
The eCon software is destined for the conguration of the trans-
ducer. One must connect the transducer to a PC computer through the
Rs485 converter, if the communication will be performed using RS485
interface or directly through the USB port and after selecting
Multi- transducer the congure the connection (g. 9.). : address 1, baud,
rate 9600 kb/s mode RTU 8N2, timeout 1000 ms and the suitable COM
port under which the controller of the transducer has been installed.

5.4.1 Setting of Transmission Parameters
After choosing the group – transmission parameters, it is possible to
congure following elements:
a) address – address for the communication with the Multi
-transducer through the RS-485 interface from the range
1...247. The value 1 is normally set up by the manufacturer.
b) baud rate – the communication rate through the RS-485
interface from the range (4800, 9600, 19200, 38400 bit/sec.)
The value 9600 is set up by the manufacturer.
c) transmission mode – The transmission mode through the
RS485 interface from t he range (RTU 8N2, RTU 8E 1,
RTU 8O1, RTU 8N1). The transmission mode is normally
set up on RTU 8N2 by the manufacturer.

5.4.2 Setting of Measurement Parameters
After choosing the group: Meter parameters following elements can be
congured (g. 11.):
a) Current transformer ratio. The multiplier is used to
recalculate the current in the transformer primary
side. It is set up on 1 by the manufacturer.
b) Voltage transformer ratio. The multiplier is used to
recalculate the voltage in the transformer primary
side. It is set up on 1 by the manufacturer.
c) Way to synchronize the mean power:
- 15 minutes’ walking window – mean power PAV
will be recalculated for the last 15 minutes, actualized
every 15 seconds, i.e. walking window,
- measurement synchronized with the clock every 15, 30
or 60 minutes - mean power PAV
will be actualized every
15, 30 or 60 minutes synchronized with the external real
clock (g. 12).
It is set up on the walking window by the manufacturer.

5.4.3 Erasing of Watt-hour Meters and Extremal Values
After choosing the group:
Service parameters following commands
are possible to carry out(Fig13.) :
a) erasing of watt-hour meters. All watt-hour meters of active
and reactive energy are erased.
b) erasing of active mean power.
c) erasing of averaging power archive.
d) erasing of min. and max. values. The currently measured
value is copied out to the minimal and maximal value.
