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. 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 . . . 2. 1 Diagrams Meters reset v 21 22 28 28 v Energy Meters Management MULTI TARIFF 27 This function allows the management of the meters according to many periods per day and three periods per year: WINTER, SUMMER and HOLIDAY. To program the parameters relating to the winter season, simply follow the same procedure (holidays) described on page 25 from No. The parameters of the SUMMER season are automatically set by the instrument as a difference between the previous two periods of the Year. To enable the setting of the daily time periods, press when the WINTER or SUMMER seasons are highlighted. To reset your choices and/or go back to the previous menus, use the key. To program the HOLIDAY period, follow the procedure on page 25 from No. 17. The periods WINTER and SUMMER are conventional seasons mainly used to manage in the best way the different energy costs during the year. The reminds from letter a) to d) are also valid for the MULTI TARIFF function. The next page shows a few examples of programming the various time periods.

Reset of the Energy meter The "RESET" menu allows you to reset the energy meters. Press to enter the menu, then use and to select the type of reset you prefer. Confirm the selection by means of the key: the instrument displays the following message: PAY ATTENTION, ALL THE METERS WILL BE RESET!!WILL YOU CONTINUE? v 23 Dual tariff Digital outputs 22 30 v Outputs / Other settings To conclude the RESET procedure, press the TARIFF SELECTION menu, press . 29 ; to go back to The reset procedure allows the user to choose among the following different choices: ALL: reset of all the energy meters (imported/ exported energies); TOTAL + : reset of the imported energy meters (+kWh, +kvarh); TOTAL - : reset of the exported energy meters (-kWh, -kvarh); PARTIAL + : reset of the partial imported energy meters (+kWh, +kvarh); PARTIAL - : reset of the partial exported energy meters (-kWh, -kvarh). s HARMONIC ANALYSIS This function enables the display of the windows relating to the harmonic analysis. Press to enter the menu; then, use the and keys to select the phase where you want to enable the harmonic analysis.
