Optical port and communication

WM5 thanks to its great flexibility allows to set in the menu (pls see

the relevant section) also the modules being installed in the base (display module). In order to make the programming of the modules easier, it is advisable to note the identification code (ex. AO2050) and the relevant installation slots (A, B, etc.): we suggest to fill in the special module on the last page of this manual.

The front optical port allows a fast and practical communication between PC and instrument. Thanks to the WM5Soft software it’ll be possible to read the measurements and programm the instrument even if the latter is already installed on the electrical board.

ual alarm, fixed light for a real alarm).

Graphic display.

This key allows the user to access programming (only page 00) or the details of the measurement.

Keys allowing the user to scroll the measuring pages, display the details relating to the measurements: dmM=dmd maximum value, dmd=avg value, max=maximum value, min=minimum value. In the page relating to the meters it’s possible to read the value of the energy counted per month (JAN...DEC), per tariff (T01...T12) and per phase (L1, L2, L3). The contemporaneous pressure of these keys also allows the adjustment of the display

When the instrument is switched on, the operating system will be loaded; this implies a short waiting time (during this phase the display shows a sand glass which will stop moving only when the loading phase is completed). Then, the instrument will start measur-

ing and will display the window on the left. This page, called "P00" page, is the only page which can be configured by the user who can choose, by means of the programming, which variables are to be displayed in the 3 sections

(a, b, c) (see “display page” in the program-

ming menu). The (d) section indicates the consumption of the measured energy (kWh and kvarh), a graphical indicator (d1) allows a quick reading of the % value relating to the active system power being used with reference to the installed power value previously set in the instrument. In the other measuring pages, the variable type displayed in the four sections (a, b, c, d) is pre-established and cannot be modified. The display of the lower part of the display is common to all measuring pages.

Let’s for example take into consideration the following tariff plan decided by the energy supplier for December. The working week is from Monday to Friday, while the weekend is made by Saturday and Sunday. During the working days there are two different tariffs with the following time periods: TARIFF 4 (T4) from 8

m to 5 pm, and TARIFF 3 from 5 pm to 8 am., while during the week

a end there is only one time period and therefore a single TARIFF (T2). The first thing to do is to program the week type (4 - 6), the working days will be indicated as follows: Monday (W), Tuesday (W), Wednesday (W), Thursday (W), Friday (W). While the weekend (Holidays) will be indicated as: Saturday (H), Sunday (H). As a consequence, the time periods relating to the working weeks will be divided into the following lines (8 - 13): First line: START TIME = 00, END TIME = 8, START DATE = 01/12, END DATE = 31/12, then select “WORKING” and TARIFF “3”. Second line: START TIME = 8, END TIME = 17, START DATE = 01/12, END DATE = 31/12, then select “WORKING” and TARIFF “4”. Third line: START TIME = 17, END TIME = 24, START DATE = 01/12, END DATE = 31/12, then select “WORKING” and TARIFF“3”. Moreover, a 4th line will be necessary to identify the NON-WORKING days other than the week end (Saturday and Sunday): for example December 25th and 26th. Fourth line: START TIME = 00, END TIME = 24, START DATE = 25/12, END DATE = 26/12, then select “HOLIDAY” and TARIFF “2”.

- Set set-point 1: Set 1 = 235V

- Set set-point 2: Set 2 = 215V Choose to which digital output the alarm you are programming is to

be addressed (the “C0” digital output is to be previously enabled to the “alarm” function; in the same menu it’s possible to select the desired type of output: “ND or NE”).

- Should a DELAY ON (delay on activation) be required, set the desired number of seconds: “5 seconds”.

- Should a DELAY OFF (delay on deactivation) be required, set the desired number of seconds: “5 seconds”

- Choose the kind of logic with which the alarm is to be treated: “OR” (see examples of logic alarm: AND/OR).

The disconnection of a load when a set value of absorbed power is required. For example when 300kW are exceeded, the alarm occurs and a set load is disconnected. An UP alarm is selected. Below you’ll find the recommended programming:

- Choose if the disabling of the first alarm status from the switching of the instrument is to be enabled or not: “OFF”

- Set set-point 1: Set 1 = 300kW

- Set set-point 2: Set 2 = 295kW

- Choose to which digital output the alarm you are programming is to be addr

essed: “D0” (the “D0” digital output is to be previously enabled to the “alarm” function; in the same menu it’s possible to select the desired type of output: “ND or NE”). Should a DELAY ON (delay on activation) be required, set the

Alarm 01

Programming WM5 96

The instrument is able to manage 2 types of alarms:

1. Real alarm = when the alarm is connected to a digital output (relay output or open collector output). The activation of a real alarm causes the switching at fixed light of the “AL” LED on the

ront of the instrument.

2. Virtual alarm = when the alarm is not connected to any output. The ctivation of a virtual alarm causes the switching at blinking light of the

a “AL” LED. In case a virtual alarm and a real alarm occur at the same time, the latter has the prevalence over the control of the above mentioned LED (therefore it will be ON with a fixed light). By exploiting the OR and AND functions, it’s possible to connect together more than one virtual alarm and direct them together to one digital output (relay output or open collector output). In any case the limit of 16 programmable alarms will still be valid.

Alarm 02

The above drawing explains the operation of the alarms described in the example. Having the “OR function been chosen for both the alarms, the operation of the digital output can be r

epresented by two contacts in parallel. The enabling of

only one of the two alarms will enable also the digital output.

ower retransmission by means of a 0-20mA analog output.

It’s necessary to measure a consumed power up to 100kW and retransmit this value by means of a signal from 4 to 20 mA: the module to be used is AO2050 (2x from 0 to 20mA), the instrument is to be programmed as follows:

VARIABLE: W∑ (system active power). MIN OUT: 20.0% means 4 mA the calculation to be carried out is the fol-

lowing: (100*minimum output) / fullscale output =100*4mA/ 20mA=20%. MAX OUT: 100.0% means 20mA, the calculation to be carried out is: (100*maximum output) / fullscale output = 100*20mA/20mA= 100. MIN IN: 0,0k; the multiple k,M,G can be selected on the instrument according to the chosen VT and CT values. MAX IN: 100.0k; the k, M, G multiples can be selected on the instrument according to the selected VT and CT values.

Transmission of active consumed and generated power by means of -5/+5mA analog output.

It’s necessary to measure both the consumed active power up to 100kW and the generated active power up to -100kW and retransmit this value by means of a signal from -5 to +5mA: the module to be used is AO2052 (2x from -5/+5mA), the instrument is to be programmed as follows:

VARIABLE: W∑ (system active power). MIN OUT: -100% means -5mA, the calculation to be carried out is:

(100*minimum output)/ fullscale output= 100*5mA/-5mA=-100%. MAX OUT: 100,0% means 20mA, the calculation to be carried out is: (100*max output)/ fullscale output= 100*5mA/5mA= +100%. MIN IN: -100,0k; the multiples k,M and G can be selected on the instrument on the basis of the VT and CT values. MAX IN: 100,0k; the multiples K, M and G can be selected on the instrument depending on the VT and CT values being selected.

Retransmission of the POWER FACTOR (PF) by means of the 0-20mA analog output.

It’s necessary to retransmit the whole range of the admitted values for the PF with a signal from 0 to 20mA. Particular attention must be paid to the value of the PF variable which may vary from C0,001 and L0,000 (for each phase): these values will be retransmitted and will then correspond to 0 and 20 mA. When the PF will have a value equal to 1, being in the middle between C0,001 and L0,000, the value of the output will correspond to the middle of the scale, that is 10mA. As a consequence, the instrument will have to be programmed as follows:

VARIABLE: PF L1 (or L2 or L3 or PF∑). MIN OUT:0,0%. MAX OUT: 100,0%. MIN IN: C0,001 (the C symbol shows a CAP MAX IN: L0,001 (the L symbol shows an INDUCTIVE value). L0,001

Example 1

How to stabilize the value of the VL-N variable displayed on the

isplay, fluctuating from 222V and 228V.

The parameters of the digital filter have to be programmed as follows:

ANGE:the variable has fluctuations within the mean value whose

amplitude is equal to ±0,75% of the full scale rated value of the variable itself (obtained by the following calculation: (228-222)/ 2= ±3V, then ±3*100/400V= ±0,75% where 400V is the phase-neutral rated value of an AV5 input). The “range” parameter, representing the action range of the digital filter, is to be programmed to a value which must be slightly higher than the percentage amplitude of the fluctuation: ex.

1.0%.

COEFFICIENT:if the new value measur

the action range of the filter, the new displayed value is obtained by adding algebrically the previous value to the variation divided by the filtering coefficient. As a consequence, a value higher than this coefficient implies a longer settling time and therefore a better stability. You generally obtain the best result by setting the filtering coefficient to a value equal to at least 10 times the range parameter value. In the following example: 1,0*10=10, the stability of the filtering coefficient can be improved by increasing the filtering coefficient, the admitted values are included within 1 and 255.

), fluctuating between 300kW and 320kW (the load is connect-

(W∑ ed to the instrument by means of a 300/5A CT and a direct measure of the voltage).

The parameters of the digital filter must be programmed as follows: RANGE: the variable has fluctuations within the mean value whose

2,78% of the full scale rated value of this vari

amplitude is equal to able. This value is obtained by the following calculation: (320-300)/ 2= ±10kW, then ±10*100/360kW= ±2,78%, where 360kW is the rated value of the System Active Power of an AV5 input, at the above mentioned CT and VT ratios and obtained by means of the following formula: (320-300)/ 2= ±10kW, then ±10*100/360kW= ±2,78%, where 360kW is the rated value of the System Active Power of an AV5 input at the above mentioned CT and VT ratios and obtained by means of the following formula: “VLN * VT * IN * CT * 3” where VLN = rated input voltage (400V for the AV5 input), VT= primary/secondary ratio of the voltage transformer being used, IN = rated curr input), CT = primary/secondary ratio of the voltage transformer being used (in this example “400*1*5*60*3=360kW). The RANGE parameter, representing the digital filtering coefficient action range, is to be programmed to a value which must be slightly higher than the percentage of the fluctuation: ex. 3.0%. COEFFICIENT: if the new value acquired by the instrument is within the filtering action range, the new displayed value is obtained by adding algebrically the previous value to the variation divided by the filtering coefficient. As a consequence, a value higher than this coefficient implies an higher settling time

phase current 1), fluctuating within 470V and 486V.

(

To be able to manage the alarm function and following activation and

eactivation of the relay, this value is not to be subject to continuous

d fluctuations. In this example we have considered using a 500/5A CT. The paramters of the digital filter is to be programmed as follows: RANGE: the variable has fluctuations within the mean value whose amplitude is equal to ±1,60% of the full scale rated value of this variable (obtained by means of the calculation: (486-470)/ 2= ±8A, then ±8*100/500V= ±1,60% where 500A is the value referred to the primary of the transformer being used). The “range” parameter, which represents the action range of the digital filter value slightly higher than the pourcentage amplitude of the fluctuation: for example 2.0%. COEFFICIENT: if the new value acquired by the instrument is within the filtering action range, the new displayed value is calculated algebrically adding to the previous value the variation divided by the filtering coefficient. As a consequence, a higher value of this coefficient implies a higher settling time and therefore a better stability. Generally speaking, the best result is obtained setting the filtering coefficient at a value equal to at least 10 times the value of the range parameter. In the example: 2.0*10=20. To improve the stability you can increase the filtering coefficient, the admitted values are within 1 and 255.
