S v 1. 2. . . . 2. 1 w w The prescaler (PrESCAL) sets the weight of the input pulses of the digital input module; e. g. : by setting the prescaler at 10, for each received pulse the meter increases by 10 (10, 20, 30, etc. ). The range of the prescaler varies from 0. 1 to 100. 0. Main Menu Digital Outputs v 9 9 22 16 v Programming 15 The increase of the Water, Gas meters, the selection of night/day tariff of the gas meters or the change of tariff (t1, t2 t3, t4) is carried out thanks to the combination of the input pulses to the AQ1038 or AQ1042 digital input module, according to the following table: SETTING OF DIGITAL INPUTS IN 3 ON OFF ON OFF ON IN 2 ON ON OFF ON RESULT INSTRUMENT Setting "tot Prd" Display of total and partial multi-tariff energy meters. Tariff 1 Tariff 2 Tariff 3 Tariff 4 Setting "tot 1. Cn" Display of total en. meters and GAS day/night tariff. OFF Increase GAS night tariff of GAS meters GAS day tariff (*) Setting "tot 2. Cn" Display of total energy meters, GAS and WATER. Increase Increase of of WATER GAS meters meters (*) (*) (*) The pulse corresponds to an increase of the various meters by the pre-set weight. If the IN 1 contact is closed (3 digital inputs module), the programming from key pad is inhibited. The synchronisation starts at the status modification of the digital inputs (IN2 and IN3) when the instrument is set to "tot" or "tot-Prd". Energy Meters Digital Output 2 v 13 9 22 19 v 16 S Programming s Digital Outputs Digital Output 1 This function enables to set the parameters of the digital outputs. Choose the "diGout" function by means of the v and w keys, to enter the menu press S . Then, set the following parameters: VAr: choose the variable to be associated to the alarm activation by means of the v and w keys and confirm with S . When the instrument asks for the reset, choose, by means of the v w keys: "no" to avoid the reset or "yes" to confirm it. Then, press S to carry out the command. S v RESET s How to prevent the programming by key-pad It is possible to prevent any access to programming by modifying the switch in the power supply slot (see the drawing on the left), or closing the contact N 1 of the digital input module if present. Turn the switch using a little screwdriver. - Lock programming. Retransmittable meters What is ASY v 17 10 24 v Useful Information 23 The variables measured by the instrument are correct if the polarities of the inputs have been observed (as shown in the figure below); if not, measuring and retransmission errors may occur due to the wrong direction of the current flowing in the primary / secondary of the connected current transformer. Example 2 "Use of digital filter": it's necessary to stabilize the displayed value of the VL1-N variable that varies between 222V and 228V. The parameters of the digital filter are to be set as follows: · rnG: the variable varies within the average value, the amplitude of which is equal to ±1. 3% of the variable's rated value, calculated as follows: (228-222)/2=±3V, then ±3*100/231V=±1. 3%, where 231V is the phase-neutral rated value of a 400V input range. The "range" parameter, that corresponds to the action range of the digital filter, is set at a value which is slightly higher than the percentage amplitude of the fluctuation: e. g. · CoE: if the new value acquired by the instrument is within the filter's action range, then the new displayed value is calculated by summing algebraically to the previous value the variation divided by the filtering coefficient. As a consequence, a value which is higher than this coefficient implies a longer settling time and therefore improves the stability. The latter can also be improved by increasing the filtering coefficient: the admitted values are within 1 and 16. Enter the value in consecutive attempts until you reach the desired stability. End of Programming Dimensions v 21 25 27 v 24 Useful Information s What is ASY The ASY variable allows the user to control the symmetry of the delta voltages (for systems without neutral) and star voltages (for systems with neutral). [. . . ] The outputs can be connected to total and/or partial en. Pulse duration: ON=220 ms, OFF 220 ms according to DIN43864 Insulation: By means of opto-couplers, 4000 VRMS between output and measuring input, 4000 VRMS between output and power supply input. Notes: outputs can be open collector or relay type (for the relay output refer to the technical features described in the alarms). Electrical diagrams v 35 v 36 40 38 Technical Features Alarm outputs (optional) Number of outputs: up to 2, independent Alarm type: up or down alarm, phase asymmetry Control on the variables: All variables listed in the paragraph "retransmitted variables" on page 24 can be controlled. Alarm set-point: can be modified from 0 to 100% of the displayed electrical scale. [. . . ]
