Then, press 7 **S** to carry out the command. _Serial port_ _Up/down alarm_ _**21**_ _**15**_ _**7**_ ## _**18 Useful Information**_ ~~Ce~~ ## I _**How to prevent the programming by key-pad**_ It is possible to prevent any access to programming by keypad by modifying the selector under the power supply slot (see the drawing on the left), or closing the contact number 1 of the digital input module, when present. Selector: turn the selector with a little screwdriver. - **Free** programming. - **Lock** programming. **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.** ## I **Setting Examples** **Example 1 “Analogue output”:** take the measure of a power consumed up to 100kW, and retransmit it with a signal from 4 to 20 mA; the module to be used is AO1050 or AO1026 (single or dual output from 0 to 20mA), the instrument must be set as follows: - VAr: (variable), W ∑ (system active power) - LoE: (minimum electrical scale) 0.0 K; the K and M mul- _Digital outputs_ _What’s ASY_ _**20**_ _**13**_ _**21**_ _**19**_ ## _**Useful Information**_ ~~es~~ tiples are automatically selected by the instrument according to the selected VT and CT values; • HiE: (maximum electrical scale) 100.0 K; the K and M multiples are automatically selected by the instrument according to the selected VT and CT values; • LoA: (minimum electrical scale of the analogue output) 20.0% for 4mA, the calculation to be carried out is: (minimum output value/ full scale output value)*100 = (4mA/20mA)*100 = 20% • HiA: (maximum electrical scale of the analogue output) 100.0% for 20mA, the calculation to be carried out is: (maximum output value / full scale output value)*100 = (20mA/20mA)*100 =100% **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. 2%. • 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. _Reset min and max values_ _Mounting_ _**23**_ _**17**_ _**21**_ _**18**_ _**20 Useful Information**_ ## I _**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 variable is calculated according to the following formula: Vmax - Vmin ASY= *100 Vavg Where: Vmax is the max. value among VL1-N, VL2-N, VL3-N Vmin is the min. value among VL1-N, VL2-N, VL3-N Vavg is the average: (VL1-N, VL2-N, VL3-N)/3 The variable is not displayed by the instrument, but it can be retransmitted by the analogue or RS422 / 485 output and can be controlled by means of the alarm.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 540,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
