Select WHOLE YEAR and confirm with to enter the relevant menu; now you can enter the programming of the daily period as follows: 1- press : the first box (trf=tariff) is highlighted; 2- press again: the TARIFF box will appear on the lower part of the display; now you can choose the tariff (from 1 to 4, e. g. : 1) by means of the and keys; v 17 Min/Max values Energy Meters Management 28 24 v Energy Meters Management 23 1. 2. . . . 2. 1 Proceed with the same principle for the following rows. Diagrams 3- press the key again; the "endtariff" hour is highlighted; 4- press the key again; the HOURS box will appear on the lower part of the display; now you can choose the hours - e. g. 5- press the key again; the "end tariff" minutes will be highlighted; 6-press the key again: the MINUTES box will appear on the lower part of the display; now you can set the minutes - e. g. 7-after the confirmation of the last setting, press and you are back to the selection of the first "trf" parameter you have highlighted. The "starting hour" of the following line becomes equal to the "end hour" you have just selected. Only when the "trf" parameter is highlighted, you can scroll the parameters and modify them: use the key to access to the key to move parameter; use the from left to right and the key to move from right to left. 8- Press to exit the programming of the parameters of the relevant row (no boxes are to be highlighted); 9- press and to select one of the other programming lines; the pointer on the right shows the line where the user can modify the parameters (points from 1 to 7). Reset of the energy meters v 21 22 28 28 v 24 Energy Meters Management a) the day can be divided into up to 8 different periods connected to up to 4 different tariffs according to the following working principle: 20 18 16 22 24 2 4 6 8 trf1 14 12 10 + kWh - kWh + kvarh - kvarh 1 Imported active energy Exported active energy Imported reactive energy Exported reactive energy The measured energy (partial energy) is placed in TARIFF 1 when the time period is from midnight to e. g. 8:00am, in TARIFF 2 when the time period is from 8:00a. m. and again in TARIFF1 when the time period is from 08:00p. m. The total measured energy is the result of the sum of all the partial measures as shown in the figure below: + kWh - kWh + kvarh - kvarh + kWh - kWh + kvarh - kvarh 1 trf1 20 18 16 22 24 2 4 6 8 trf1 14 + kWh - kWh + kvarh - kvarh T 12 10 trf2 2 b) the starting point of the first time period is always 24:00 (midnight) and cannot be changed; c) the starting point of the following period is always the end hour of the previous time period; d) the daily loop is closed by setting 24:00 as last hour of the last time period (to follow this procedure see point 4 on the previous page), confirm the setting by pressing and to go back to the TARIFF SELECTION menu. v 19 Average power calculation Trf holiday period 22 28 26 v Energy Meters Management 25 PROGRAMMING THE HOLIDAY PERIOD To program the HOLIDAY period, proceed in the following way. 10- Choose HOLIDAY in the SEASON menu by means of the and keys and confirm with : the HOLIDAY menu will be displayed (see figure on the left); 11-press : the month corresponding to the start date will be highlighted; 12-press : the box for setting the month will be enabled; and to select the 13-use desired month (from 1 to 12); 14-press the key to confirm the selection and move to the next parameter: day setting; 15-press the key again to open the box where the day is to be set; 16-use the and keys to select the desired day (from 1 to 31 depending on the previously selected month); 17-press the key to confirm the selection and move to the next parameter. 1. 2. . . . 2. 1 On page 26 To reset, press . v 23 Dual tariff management Display of harmonics 21 28 29 v 26 Energy Meters Management To program the "end date" follow the same procedure described above from No. After confirming the "end" day by means of the key, the HOLIDAY box is highlighted to indicate the conclusion of the HOLIDAY period programming cycle. You can also use the (moves from right to left) and (moves from left to right) keys to scroll along the available parameters. It's possible to choose the tariff to be associated to the HOLIDAY period according to the following procedure: From page 25 starting from the box on the previous page, number 10, press the key again: the instrument will display the box shown on the left. Press : the box of the "trf" value is highlighted; key again: the instrupress the ment will display on the lower section the box where the tariff is to be set. Select the desired tariff (from 1 to 4) by means of the and keys and confirm it with .
