WIRING DIAGRAMS Power supply The SM ART96 Piú can be supplied with nominal 240/230 Vrms, or with 120/115 Vrms as shown in the following picture: FIG 11 - Power supply connections REMARK: since this instrument is not provided with any fuse, the system must be protected with a 0.1 A type T fuse during installation. After connecting to the power supply, the device is switched ON and the first page of the measurement menu is displayed.

SMART96 Piú 5.2 DUCATI energia S.p.A. Typical diagram for direct connection FIG 12 - Direct three-phase connection on the voltmeter and ammeter inputs IMPORTANT: Check that the voltmeter and ammeter terminals are connected to the corresponding voltages and currents on the line. The passage of current in the correct direction is automatically determined by the analyser by means of the voltage and current control of each phase at power up (see section 5.

SMART96 Piú 5.3 DUCATI energia S.p.A. Typical diagram for indirect connection FIG 13 - CT and VT indirect three-phase connection IMPORTANT: Check that the voltmeter and ammeter terminals are connected to the corresponding voltages and currents on the line. When using CT or VT transformers, it is necessary to set the transformation ratio from the relevant page of the configuration menu (Setup). For instance, when using an 250/5 CT, the transformation ratio (KA) to be set is 50 (see 6.4.3. and 6.4.4).

When using CT or VT transformers, it is necessary to set the transformation ratio from the relevant page of the configuration menu (Setup). For instance, when using a 250/5 CT, the transformation ratio (KA) to be set is 50 (see 6.4.

SMART96 Piú 5.5 DUCATI energia S.p.A. Typical wiring diagram for single-phase systems FIG 15 - S ingle-phase connection CAUTION: When fitting you should arrange to feed the ammeter cable into the ferrule on the far right corresponding to phase L1 and connect voltmeter cables to terminals L1 and N. Then, set CFG = 13 on the relevant page of the setup menu in order to place the instrument in the single-phase operating mode; the values of the quantities relating to phase L1 are displayed.

SMART96 Piú 5.6 DUCATI energia S.p.A. Typical wiring diagram for balanced three-phase systems FIG 16 - Balanced three-phase connection Having checked that all three-phase loads are balanced, is it possible to minimise system installation costs using a CT on one phase (L1) only, thus avoiding the need to fit the other two on the remaining phases.
PAGE 23
SMART96 Piú DUCATI energia S.p.A. This means that the fitter does not have to worry about the direction of the ammeter wiring or set special configuration in the setup menu. It should therefore be noted that the device works on two quadrants. Please note that this option can be disabled using the corresponding menu in the setup pages. In this case, using two SM ART96 Più installed in opposition, it could be measured the cogenerated energy. 5.

SMART96 Piú DUCATI energia S.p.A. Setting for both instruments the cogeneration enabled, it will be restrict the TA direction and, while the first SM ART96 Più counts only the input energy (absorbed by the user), on the contrary the second counts only the cogenerated energy (generated by the user). The first SM ART96 Più will measure the active energy and the reactive energy absorbed by the user, while the second SM ART96 Più will measure the active energy and the reactive energy generated by the user.

SMART96 Piú DUCATI energia S.p.A. Practical example: • set value for pulse generation = 125 Wh • entered KV value = 20 • entered KA value = 50 Consequently, the true value associated with the single pulse is obtained with the following formula: 125*20*50 = 150kWh. Remember that if the output is enabled as a pulsed output, then it is automatically disabled as an alarm output and the pulsed output is disabled when the value is set to 0. 6.4.

SMART96 Piú 6.4.9.1 DUCATI energia S.p.A. Alarms 29 ÷ 34: Disconnection Function (D.F.) This function is used to manage a simple forecasting load-disconnecting algorithm, connected to alarms on quantities 29, 31 and 33 which are a mean active power threshold and 30, 32 and 34 which are a mean apparent power thresholdv, respectively. The function means you can avoid exceeding the mean power contractual value, since the alarm output can be used to disconnect a load.

SMART96 Piú 8. DUCATI energia S.p.A. TIPS FOR A CORRECT INSTALLATION In order to avoid misreadings and miscalculations of the data processed by SMART96 Piú beware of the following: S ETUP Both KV (voltmeter constant) and KA (ammeter constant) must be correctly entered to get a correct calculation of the processed parameters. K expresses the ratio between the primary and the secondary of the transformer, be it voltmeter or ammeter. Example: with 2000/5 CT, KA will be 2000/5=400.
