USE

1. RECEIPT & STARTING OF THE INSTRUMENT

Check that the instrument configuration (see label on the case side) corresponds to yourorder. In case of servicing or on-line assistance, the instrument’s programme version and itsidentification number will be necessary (they can be read with the µconsole or with the PCprogramme). Latch the instrument on a DIN rail. Connect the power supply (see wiring diagrams),

The ON tension LED lights up. The instrument then starts to measure. It has a standard configuration (unless indicated onyour order). The instrument can now be programmed, preferably before connecting the measure signals. Then connect all signals : see wiring diagrams. The standard communication parameters of the PC software or the digital output are thefollowing : slave number = 250 speed = 9600 bauds without parity 1 stop bit

2. ORGANISATION OF THE FRONT FACE

IN CASE OF PROBLEM …

The instrument won’t light up : Check the presence of an auxiliary power supply(even in the case of a self-powered instrument)

The instrument won’t measure : Check the presence of the measure signals.Check the programming.

If LED « ON » flashes : A wiring or configuration error has surged.See chapter 6 – use : « list of the errors ».

If the RS485 does not work : Try to cross the wires, try the function analysis of patterns(code 887 on the µconsole)

4. ODD CASE OF THE SIGNED PARAMETERS :

Powers are always transmitted on the digital output with their sign.Moreover, the cosine display allows a determination of this sign :

- If the programmed COS type is electrical, the reactive power sign can be known, theCOS indicates the load nature (L or C on the micro-console, + or – on the software)

- If the programmed COS type is mathematical, the active power sign can be known, theCOS indicates the current direction : + = Generating and - = Receiving

5. USE OF THE « CUT OFF »

The « cut off » is a programming option on the instrument that allows separate setting of thedisplay to zero for U and I low values (see chapter « programming of the CUT OFF »).Once the menu is validated, the instrument will measure the values on its inputs and enforce tozero any value under the programmed « cut off » in percentage of the full scale.

3-2. CONFIGURATION OF AN ANALOG OUTPUT

3-21. Operating mode of an analog output – General case :To configurate a current output, you must define :

- The output type : 4-20mA , 0-20mA , -20+20mA , -5+5mA , -10+10mA , 0 5mA , 0 10mA- the n° of the parameter dedicated to the output (see list of parameters)- the down and full scale for the measured parameter- The return value for the saturation in case of alarm

N.B : on setting on tension , the output will deliver –22mA during a few seconds.

Example : output 4-20mA for Vr from 50kV to 500Kv. Example : output –20+20mAfor Q from –10kW to +10kW.

3-22. Odd case of the power factor ( COS) :

The power factor can be transmitted on a current output in 3 different ways : MATHEMATICAL COSINE : the cosine sign indicates the direction of current (receiving or

generating)

Example : the load can be either current receiving or generating, a cosine between –0.5 and+0,5 is sent on a 4-20mA output

ELECTRICAL COSINE CENTERED ON 0 :The cosine sign indicates the load nature (capacitive or inductive).

Example : a network is measured with a cosine compensation by capacitors , the load nature isinductive, but if you compensate too much you may obtain a capacitive load. The cosineoscillates around +/- 1. A 4-20mA ouptut is programmed for a cosine between –1 and +1.

To avoid the jumps from 4 to 20mA, use following configuration :

ELECTRICAL COSINE CENTERED ON +/-1 :The cosine sign always indicates the load nature(capacitive or inductive, but the current output will be centered on a +/-1 cosine).

Example : taking up the previous example ,the 4-20mA output is programmed for a –0.5 to +0.,5 cosine

As the cosine oscillates between +/-1 , the current output remains around 12mA.The unlinear transfer funtion forbids the use of a digital panel meter on the current output.

4-3. Addresses of the measuresThe value read in the 1

sttable gives the measure module (on 4 significant ciphers, resolution x10) To know the unit

and the decimal point of this measure, they must be read in the 2nd

table.The unit and decimal point do not vary. They depend only on the programmed CT/VT ratios.Hence, the 2nd table does not need to be read permanently. This allows a quick reading of measures coded ona single integer.

Example : CT ratio = 5kA / 1A, display =5.00kA5000 is transmitted in the table of measures , and 3/1 is transmitted in the table ofdecimal points / units

4-4. Format of the measures

-Coding of an energy :the energy is coded on 4 bytes (double integer) : [byte1-byte2-byte3-byte4] from LSB to MSB, this means Energy =byte1 + byte2.256 + byte3.256² + byte4.256

3

-Coding of the measures :measures are coded on 2 bytes (signed integer) : [byte1-byte2] from LSB to MSB, this means measure = byte1 +byte2.256

The format of the measures transmitted by the digital output depends on the performed programming :

Format Nr1 2143-transmission of an energy : ( Energy = byte1 + byte 2.256 + byte 3.256² + byte 4.256

3)

sent byte = byte 2 2nd

rdsent byte = byte 4 4

thsent byte = byte 3

-transmission of the measures : ( Measure = byte 1 + byte 2.256 )1

stsent byte = byte 2 2

ndsent byte = byte 1

Format Nr2 4321- transmission of an energy : ( Energy = byte 1 + byte 2.256 + byte 3.256² + byte 4.256

3)

1st


sent byte = byte 33







3)

sent byte = byte 23





ndoct sent byte = byte 2


3)

Example in format 2 – 1 / 4 – 3 :Measure = 2000 = 208 + 7 x 256 transmission = 7 and 208Energy = 1503 in the LSB and 43461 in the MSB =223 + 5 x 256 + 197 x 256² + 169 x 256

3transmission = 5 – 223 – 169 – 197

The energy is transmitted with the same unit as total powers.For harmonics, the harmonic value is coded in % a an integer between 0 and 100

WIRING

1. WIRING RECOMMENDATIONS

The input network (U and I) may carry significant disturbances, and the whole processing chainmay be disturbed. In order to avoid this, the parasites immunity may be rendered much betterby respecting following rules :

Do not connect too close : the input network and the power supply wires. Do not connect too close : the input network and all the output wires (pulse outputs, relay

outputs …) Use for all outputs shielded cables connected to the GND on both ends.

In order to avoid any influence of the current intakeon the voltage measure, connect CTs before VTs.

7. WIRING OF THE DIGITAL OUTPUT RS485- The end of line resistor Zo on the master reduces the influence of reflections on the lines.

For speeds <9600 bauds the resistor is not necessary, from 1000m at 9600 bd and 700mat 19200 bd it is compulsory.

- The use of shielded cables is preferable to reduce the environment influence. Connectthe earth to both ends of the cable shielding, and the GND to one of the ends.

- In case of communication problem : invert Rx and Tx polarities on the master. Check thatthe master’s emission arrives on the Tx wire.

- Switch termination and polarisation resistance Zo on the end of line instrument (120 Ohm).7-1. Wiring RS485 / 422 4 wire

CAUTION : The master must always polarise the lines. Switch the end of line andpolarisation resistors et the level of the master. If necessary place the Zo resistor on the endof line instrument (see above).

Notes : In 4 wire, the master’s emission driver must always be enabled. This is performed

either with the software if it has a selection 2/4 wire, or in the interface 485/422using a micro-switch.

In 2 wire, the master’s emission driver must be validated only if it is sending . This isperformed either with the software if it has a selection 4/2 wire, or in the interfaceRS485 using a micro-switch which validates the emission driver with the signal RTS(or DTR).

ANNEXE 1 : READING OF THE HARMONICS VIA THE DIGITAL DATA LINK

The retransmission of the harmonics on the digital output can be done in 2 different ways, according to theperformed programming :

1. Programming 1CH/H50TheTHD and the harmonics from rank 2 to rank 50 are transmitted for the selected channel to address 69Selection of the channel :The number of the channel is written (integer 0 or 3) at address 69Integer=0 : UL1 harmonic Integer=3 : IL1 harmonicThe THD of the chosen channel can then be read at address 70, and the harmonic ranks from address 71.
