1. APPLICATION

The P41 transducer is a digital programmable device destined

to measure and convert of 1-phase power network.

It enables for measurement and conversion of measured quantities into

standarised analog current signal.

Quantities measured and calculated by the transducer:

•phase voltage ................................................. U

•current ............................................................. I

•active power .................................................... P

•reactive power ................................................. Q

•apparent power ................................................ S

•active power factor .......................................... Pf

•reactive power factor ...................................... tg

•averaging active power (e.g.15 min.) ............... P

•Tangent ........................................................

•active and reactive energy .............................. Ept, Eqt,

•frequency ....................................................... f

The transducer has an archive that can store up to 9000

values of a quantity selected by a user, together with time marker.

The transducer stores maximal and minimal values for all

measured quantities. Additionally, it is possible to introduce exter-

nal transmission of measuring transformers which will be taken into

account while measuring and calculating of all measuring quan-

tities. The update time of all available quantities does not exceed

1 second. All quantities and conguration parameters are available

through the RS485 interface and USB.

The transducer output signals are galvanically isolated from input

signals and the supply. Transducer housing is made of plastic.

On the external side of the transducer there are screw terminal strips

socket – plug to which wires of a maximal diameter - 2,5 mm

2 can

be connected.

2. TRANSDUCER SET

The transducer set consists of:

– transducer P41 1 pc

– user’s manual 1 pc

– guarantee card 1 pc

– CD 1 pc

3. BASIC REQUIREMENTS AND OPERA-

TIONAL SAFETY.

In the safety service scope, the transducer meets the require-

ments of the EN 61010-1 standard.

Observations concerning the operational safety:

•All operations concerning transport, installation and commissioning

as well as maintenance must be carried out by qualied, skilled

personnel, and national regulations for the prevention of accidents

must be observed.

•Before switching the transducer on, one must check the corectness

of connections to the network.

•The removal of the transducer casing during the guarantee contract

period causes its cancellation.

•The transducer is destined to be installed and used in industrial

electromagnetic environment conditions.

•A switch or a circuit-breaker should be located near the device, easy

accessible by the operator and suitably marked.

direct measurement

Beforecarryingoutthetransducerconguration,the drivers

provided on the attached CD should be installed. The P41 transducer

uses the software, which is created in the system by the Universal Master

Bus device – Przetwornik / P41 Transducer and by a virtual port Com

named Przetwornik/ P41 Transducer attached to it. The installation

of a driver in the Windows system causes adding another serial port Com

to the list of ports serviced by the operational system.

After the transducer has been added to the USB port, the opera-

tional system will notify on the occurrence of a new device by displaying

amessagepresentedontheg.5. FoundNewWizardoftheUniversal

S B erial us willactivateautomatically.T he wizard’ssuggestionsoughttobe

followedbyselectinginstallationfromtheindicatedlocalizationandgiving

a tract for drivers, which can be found on an attached CD. The drivers are com-

patible with the following systems: Windows 2000, XP, Server 2003, Vista,

Windows 7, Server 2008, Windows 8, Windows 10. At drivers installation,

a message signaling the lack of drivers digital signature can occur. Ignore

it and proceed with further installation.

After successful installation, the system will notify on install-

inganewdevice(g.6).TwonewdeviceswillappearinDeviceManager

converter (if the communication will be carried out through RS485)

or directly through USB.

Select Connection and configure the connection (fig. 8).

For direct connections through USB: address 1, baud rate 9600kb/s,

mode RTU 8N2, timeout 1000ms and the proper port COM where the

driver of the P41 transducer was installed or through the RS485 interface

and PD10: address, baud rate, the mode in accordance with the ones

set in the transducer.

6. ARCHIVE

The direct access to the archive is destined for 15 records

containing the date, time and the value of located in the range addres-

ses1000–1092.Theregister1000isthelocalizationfortheposition

ofthe rst(the oldest)archived sample,whereas in1001 isthe loca-

lization ofthe last archived sample(the youngest). Theregister 1002

contains the value of the rst record of the fteen available ones lo-

catedinregisters1003 –1092.Entering thevalueof therst readout

record (1 – 9000) causes the data updating of 15 records to readout.

In the registers, to which samples have not been entered yet, there are

values 1e20. The archive is arranged as a circular buffer. After the nine

thousandth value has been entered, the next one overwrites the oldest

one numbered 0, the next one another one with the number 1, etc.

If the value of the register 1000 is greater than 1001, it means that the

bufferhasbeenoverowed. Forexample, thevalue15inthe register

1000 and 14 in the register 1001 means that there were more than nine

thousand samples and that the oldest samples are from the record 15

to 9000, then from the record 1 to the youngest record numbered 14.

Erasing of mean power or changing the averaging time does not erase

thearchive. Automaticledeletioncomes withthechangeof current

or voltage ratio.

The P41 transducer comes with the implemented function

that allows for updating the software from a PC with eCon software.

Free eCon program and the updating files are available         by request

from PCE. Either RS485 port and USB port can be used to carry

out the updating process.

Fig. 18. The view of program window:

a) eCon, b) program updating

Note! After updating the software the manufacturer’s settings

for the transducer ought to be set, therefore it is advisable to store

the transducer parameters before its updating using eCon software.

After eCon has been started, one ought to set serial port, baut

rate, mode and the transducer address in . Then choose the Options

P41 transducer from the menu and click the icon in order Devices Read

to read all set parameters (necessary for their later restoration). After

selecting from the menu Updating the option Device software updating,

9.3 Register map of the P41 transducer

The data in the P41 transducer is located in 16 and 32-bit

registers. Process variables and the transducer parameters are located

in the registers address area in a way dependent on the type of the vari-

able value. The bits in the 16-bit register are numbered from the small-

est to the largest (b0-b15). The 32-bit registers contain the numbers

of oat type in the IEEE-745 standard. The register ranges are

presented in the table 2. The 16-bit registers are presented in the table

4,5. The 32-registers are presented in the tables 6. Registers addresses

in the tables 4, 5, 6 are physical addresses.
