1. kVArh It should be noted that the reactive energy meter will only increase if reactive power is inductive if capacitive the meter will record no increase For each single phase the maximum energy value that the device can accumulate is 4294 9M Wh or M VArh and relates to the measurement with KA and KV 1 Then the internal value is displayed multiplied by set KA and KV transformation factors If the result of such operation is greater than the maximum value 4294 9M Wh the following string is displayed indicatin g the overflow If exceeding such value rollover occurs 1 e the phase meter is reset the display restarts from 0000 Examp le if KA 20 and K V 100 are set phase meter rollover occurs every 8589934 59 M Wh but the value displayed is when exceeding 4294 9 M Wh The maximum energy value for the three phase meter is always 4294 9 MWh or M VArh but since the three phase meter is always the sum of the 3 single phase meters overflow and rollover will always occur earlier and separately from that of each single phase Example if with KA and K V 1 the meter of L1 1500M Wh that of L2 1600M Wh and that of L3 2000M Wh the three phase meter will indicate 805 1M Wh since a rollover has occurred The minimum quantum of energy that can be displayed also available through RS485 serial protocol is 1Wh KA KV Example if set KA 30 and K V 50 a variation of the displayed value occurs every 1 502. 30 6 4 4 Setting the KA CT transformation atO sss sese 30 s SELLING 0 CO eM erat ioh MO de ii id 30 6 4 6 Selection of the measures of the last measurements page PAr ThdF normal or 31 SMART Piu DUCATI energia S p A 9 047 ACV enero PUET oP ut OUTI id 32 64 8 Reactive enersy pulsed output QUE unta di dia 33 649 Alrm oopa COUT data 33 6 4 9 1 Alarms 29 34 Disconnection Function D E 36 GALA lari Output OUT ccteasih lac thbe E E T 36 CALIDA PACS esn heeded Ee aia dic baa haat dil anes dba bald dle oA Rtas 37 AI M oan ti a a olden a a 37 6 4 13 Setting the parameters for the RS485 serial mterTac sse eee 37 GAA Address OF TING AMY Zei TT 38 6 42 15 Serial CO MmMmunication PTOLOCO P 38 ANO PASS RR 39 6 4 17 Instrument firmware version and Serial numDer 41 OS TINT pace e dl da tates 4 PERFORMANCE AND TECHNICAL CHARACTERISTICS 42 p E R STRIZ ert iE ana aN E A 42 L2 Calculated Incas re Iie io 42 EF AOE Te anaa a ems anecabadanaateunsnauaasee 43 hha A E N E T T NE E ET T E EE 43 TAL VOMS 11T 43 1 E RETETE 43 TD Dtos tanos Visual OM 44 MS EMEP OY COMU AS ASS O 44 76 Conmeurable measurement Mode 44 Tel Acera yorti Meca UEM ss 44 TO Nen e e E TTT 45 TD OP Cali RST EL aT 45 TITO Normativo Teleradio 45 TAA Tor Ch Wa LOPIMatION CAR OO RCP POE UT 46 ACCE GORI sie sewer nee ee eer rere mer ene Ea 46 S L Smart Panel Pra ME e a 46 TIPS FOR A CORRECT INSTALLATION c oooccccnnoncnnonnonconcnncnnonccnc
