■PQTSoft Remote in brief

PQTSoft Remote has been conceived to program PQT-90 by means of a data transmission from the PC to the instrument via RS232 or RS485 serial interface. The choice between one interface or the other is therefore very important for the correct operation of the instrument as shown by the following figure:

Local single PQT connected to the PC by RS232 serial port

Maximum 255 PQT’s in an RS485 local network connected to the PC by RS232 thanks to the RS485-RS232 SIU-PC converter.

Maximum 100 remote single PQT’s connected to the PC by means of a telephone network thanks to an analogue/GSM modem.

Maximum 25000 PQT’s in max 100 remote RS485 networks connected to the PC by means of a telephone network and RS485-RS232 SIU-PC.

■Configuration of PQT-90 ❑Configurations archive and remote PQT programming

PQTSoft Remote

Configuration

PQTSoft Remote manages a configuration archive that may be selected at any time. At first, when the software has just been installed, this file is empty. [1] Click on new configuration to start the programming procedure of PQT90. [2] It allows to load from PQT-90 the pre-existing programming and to modify it, if required. [3] Close the window without modifications.

❑Instrument composition...

[1] Enter the name required for the new configuration of PQT-90. [2] Select the supplied modules installed in the instrument in

the various slots. For the module AR1041 only, if it is present, also the operating mode is to be indicated as follows: “AR1041 module (slave)”: PQT-90 is enabled to the datadownload only on request of the user; “AR1041 module with analogue or GSM (Master+Slave)” modem: PQT-90 is enabled to the data download on request and to the independent transmission of SMS in case of alarm activation; “AR1041 module with GSM modem for SMS (Master)”: PQT-90 is enabled to transmit SMS messages and to send

or without analogue measuring inputs (AQ1018, AQ10109)

[2] Enables the gas and water metering. [3] Selects the ratio of the current transformer. Example: if

the CT (current transformer) primary has a current of 300A and the secondary a current of 5A, the CT ratio corresponds to 60 (that results from: 300/5). [4] Selects the value of the VT (voltage transformer) ratio. Example: if the VT primary connected to the instrument is 20kV and the secondary is 100V, the VT ratio corresponds to 200 (resulting from 20000/100). [5] Selects the serial address of the instrument when the latter is part of a network of instruments. [6] Selects the type of electrical system. If no measuring inputs (AQ1018, AQ1019) have been selected on the previous page, the box “Full scale power” will appear: select the most appropriate full scale. [7] Selects the options for the clock of PQT-90. If the option “Not to be programmed” is selected, the clock will not be programmed; to program the hour, select the option “Synchronize with PC date and hour”, the clock will be programmed with the date and hour present in the system of the PC. To make the instrument automatically switch to the summer time and viceversa, select the option “Automatic switching to summer time”.

and C2 are not available if PQT-90 is supplied with analogue measuring inputs AQ1018 or AQ1019.

❑Harmonics analysis and digital filter setup

[1] Enables the harmonic analysis on the selected phases,

activate the relevant check boxes.

[2] Selects the value of the “Range” parameter of the digital filter. [3]

Selects the value of the “coefficient” factor of the digital filter.

Example: the value of the V

L-N

variable fluctuates between 222V and 228V and it is therefore necesarry to stabilize it. The parameters of the digital filter must be set as follows:

• RANGE: the variable has fluctuations within the average value

whose amplitude is equal to ±1,3% of the rated value of the variable itself (where ±1.3% results from (228-222)/ 2= ±3V, then ±3*100/231V= ±1.3%; 231V being the rated phase-neu-

tral value of a 400V input). The “range” parameter is the action range of the digital filter and it is set at a value slightly higher than the percentage amplitude of the fluctuation: e.g. 1.5%.

❑Digital input working mode setup

[1] Enables digital input A1 (input 1 of the digital input module installed in slot A of PQT-90); [2] Enables digital input A1 working mode: “Gas meter” or “kWh- meter”. [3] Set the amount of the input pulse (pulse/m

ex.: if the value 10 has been set, then 10 input pulses will be required for the following gas metering: 1m

). [4] Enables digital input A2 (input 2 of the digital input module installed in slot A of PQT-90); [5] Choose digital input A2 working mode: “Water meter”, “Day, night tariff of the gas meter” or “kvarh- meter”. [6] Set the amount of the input pulse (pulse/m

ex.: if the value 10 has been set, then 10 input pulses will be required for the following metering: 1m

). [7] Enables digital input C1 to the function of kWh meter, C2 to the function of kvarh meter; [8] Set the amount of the input pulse (pulse/kWh, kvarh ex.: set the value 10: 10 input pulses will be necessary for the energy metering of 1kWh, 1kvarh). The input pulses C1

• COEFFICIENT: if the new value acquired by the instrument is within the action range of the filter, then the new displayed value will result from the sum of the previous value (A) to the variation (B) divided by the filtering coefficient (C), that is: [(A) + (B/C)]. As a consequence, a value higher than this coefficient, will result in a higher settling time and therefore a higher stability. Generally, the best result will be obtained by setting the filtering coefficient to a value equal to at least 10 times the value of the range parameter. In the example above: 1.5*10=15. To improve the stability, the filtering coefficient can be increased: the admitted values are within 1 and 255.

❑Setup of min. and max. values logging and relevant variables

This dialog box allows to associate some variables to the automatic logging of max and min values (from Max. 1 to Max. 12 and from Min. 1 to Min. 8). [1] Select the data to be logged activating the relevant check box. [2] Select the variable to be logged among those available in the drop-down list that will appear after clicking on the arrow on the right of the box.

Page 10

❑Logging variables selection and dmd power calculation

This window allows the user to enable the variables to be logged (Max 8) in the data memory of PQT-90 and the working mode of this operation. [1] Select the variables to be logged (Max8) activating the relevant check boxes. [2] Select if, in addition to the logging of the average values of the variables, PQT-90 is required to log also the min and max values in the time interval. [3] Select the value of the logging time interval (from 1 to 60 min.)

During the measurement, the instrument takes samples of the selected variables every 200ms approx; at the expiry of the set time interval, the instrument cal-

culates the average of the samples and carries out the data logging. The historical value will therefore be guaranteed to be highly accurate. [4] Selects the dmd (W-VA-var-PF) calculation method between FIXED and FLOATING.

FIXED SELECTION: if a value of 15 minutes is selected, the

PQTSoft Remote

Configuration

Data Logging and relevant duration

Configuration

instrument calculates the dmd value and updates it every 15 minutes. FLOATING SELECTION: if for example the value “15 minutes” is selected, the instrument calculates the dmd value and updates its value at first after 15 minutes and then every minute generating a window whose width corresponds to 15 minutes and shifts by units of 1 minute.

The following diagrams show the two working methods.

The WINTER and SUMMER time periods are conventional seasons mainly used to manage in the best way the different energy costs during the year. The reminds at steps a), b), c) d) on page 20 are

also valid for the MULTI TARIFF function.

In the SINGLE TARIFF, only one period exists, referred to the whole year. In the DUAL TARIFF, the “year” can be divided into two periods: whole year and holidays. In the multitariff, the “year” can be divided into 3 periods: winter, summer and holidays.

erated by the measured value (“max. input value”). “Min. output value”: value expressed as % of the zero of the output

range (0-20mA, 0-10V, etc.) that is generated by the minimum measured value (“min. input value”).

Example 1: to measure a consumed power up to 100kW

and retransmit it with a signal from 4 to 20mA, the module to be used is AO1026 (2x from 0 to 20 mA) or AO1050 (1x from 0 to 20mA); the instrument is to be set-up as follows:

• Variable: WΣ (active system power)

• max. input value: 100.0 kW;

• min. input value: 0.0 kW;

• max output value: 100.0% corresponds to 20mA, then: (100*max. output)/fullscale output=100*20mA/20mA =100%

• Min. output value: 20.0% corresponds to 4mA, resulting from: (100* min. output) / fullscale output= 100*4mA/20mA= 20%

Example 2: to measure both the consumed power (up to 100KW) and the generated power (up to -100kW), and retransmit it with a signal from -10 to +10V, the module to be used is AO1033 (2x ±10VDC) or AO1057 (1x ±10VDC). The parameters can be setup as follows:

• Variable: WΣ (system active power)

• Max. input value: 100.0 kW;

• Min. input value: -100kW;

• Max. output value: 100.0% corresponds to 10V, then: (100*max. output)/ fullscale output = 100*20V/20V=100%.

• Min. output value: 0.0% corresponds to -10V, then: (100* min. output)/fullscale output= 100* 0V/20V= 0%; in this case also the “total” excursion of the analogue output is to be considered, therefore from -10V to +10V=20V As a consequence, when the power is -100kW, the output will be -10V, when the power is 0, the output will be 0V and when the power is 100kW the output will be +10V. Example 3: the whole range of the values admitted for the

variable PF corresponds to values between C 0.00 and L

0.00 (for each phase) which, after retransmission, will be respectively 0 and 20mA. When PF is equal to 1 (since it is in the middle of C 0.00 and L 0.00), the output will be equal to the centre of its scale, that is 10mA. As a consequence, the instrument is to be setup as follows:

• Variable: PF L1 (or L2 or L3);

• Max. input value: L 0.001: the max input value will correspond to C if its sign is negative and to L if its sign is positive.

• Min. input value: C 0.000; the min input value will correspond to C if its sign is negative and to L if its sign is positive.

• Max output value: 100%;

• Min. output value: 0.0% The min. input value to be set for L is 0.001 to avoid any undesired variations of the analogue outputs.

■Data logging operating principle and duration

The data logging duration depends on the number of variables that you want to log (from 1 to 8), from the selected integration time (from 1 to 60 minutes) and from the activation, if any, of the max./min. logging for each time interval. The following table simplifies the duration of the data logging according to the selections. The datum logged in the selected time interval (tias shown in the graph below) results from the continuous

average of the measured values (samples). The average value is calculated with an interval of approx. 200 ms between two subsequent measurements (samples); as a result, the historical data value will be extremely accurate.

■Application bar: meaning of the icon

When the PC is going to start the connection with the remote instrument, one icon appears on the application bar [1] indicating the status of the connection. [1] Represents a modem where two “green LEDs” flash alternately during RX and TX between a PC and a PQT.

■How to use SMS messages

Once the instrument is enabled to send and receive SMS messages, the user may ask the instantaneous variables, the last available variables in the data logging, the energy meters and the alarm status. The table on next page identifies the codes to be entered in the mobile phone in order to obtain the desired information. Generic message to be sent to the instrument: “PQT. [instru- ment’s password]. [code of required information]”; then confirm the message and send it (follow the instructions given by your mobile phone).

“xxx”: access password to read the variables via SMS messages. “Log1...Log8”: last integrated variables stored in the flash memory (variables can be read only after programming them and enabling them).

Example: in order to ask information on the dmd variables, enter the following text: PQT.255.DMD; the reply will be: PQT.255: 12.45KWdmd, 16.04KVA dmd, 3.45kvar dmd,

0.79PF avg (where 255 is the password preset in the instrument).

Useful info

The variables measured by the instrument are correct if the inputs have been connected according to the right polarities (see figure below). Should the

connection not be conforming to the right polarities, measuring and retransmission errors may occur, both due to the wrong direction of the current flowing in the primary/secondary of the ammeter transformer being connected.

■What is ASY

The ASY variable allows you to control the asymmetry of the delta voltages (for systems without neutrals) and star voltages (for systems with neutral). The variable is calculated as follows:

where the first formula is to be applied to delta systems, while the minimum value calculated between the two is to be used for the star systems.

■ The software in brief

The PQTSoft Network has been developed for the data transfer from the instrument (PQT90) to the PC. The data download from PQT90 to the PC allows the reading and saving of the values logged in the 2MB memory of PQT; the values can be saved as an Excel table. The PQTSoft Network has been mainly developed to automatically download the values logged in the PQT; it is therefore necessary to configure first of all the “automatic data download” dialog boxes. The data transfer can be carried out in various modes: it depends if the PQT is part of a local or of a remote network of instruments. The figure on the following page shows the possible communication modes and the correct selection to be made in the PQTSoft Network.
