Leggere attentamente il manuale prima dell’utilizzo e l’installazione. ● Questi apparecchi devono essere installati da personale qualificato, nel rispetto delle vigenti normative impiantistiche, allo scopo di evitare danni a persone o cose. ● Prima di qualsiasi intervento, rimuovere tutte le tensioni pericolose dall’apparecchio. ●Il costruttore non si assume responsabilità in merito alla sicurezza elettrica in caso di utilizzo improprio del dispositivo. ● I prodotti descritti in questo documento sono suscettibili in qualsiasi momento di evoluzioni o modifiche. Le descrizioni ed i dati a catalogo non possono pertanto avere alcun valore contrattuale. ● Un interruttore magnetotermico va compreso nell’impianto elettrico dell’edificio. Esso deve trovarsi in stretta vicinanza dell’apparecchio ed essere facilmente raggiungibile da parte dell’operatore. Deve essere marchiato come il dispositivo di interruzione dell’apparecchio: IEC/ EN 61010-1 § 6.11.2.1 ● Installare lo strumento in contenitore e/o quadro elettrico con grado di protezione minimo IP40. ● Pulire lo strumento con panno morbido, non usare prodotti abrasivi, detergenti liquidi o solventi. Descrizione • Il DCRM2 consente di controllare la corrente reattiva di un impianto, eliminandola dal totale richiesto al fornitore di energia e quindi rifasando il carico al migliore cosfi possibile. • Esso è in grado di controllare la connessione di max 2 banchi di condensatori. • Ciascuno dei due banchi di condensatori può essere abilitato singolarmente e la sua potenza può essere definita tramite un trimmer dedicato. • E’ inoltre possibile regolare il tempo di inserzione e disinserzione dei condensatori, aggiustando quindi la velocità di reazione del sistema. • L’apparecchio è utilizzabile sia in configurazione trifase che monofase. Caratteristiche • Inserzione mediante TA esterno con secondario /5A. • Riconoscimento automatico del senso di collegamento del TA (diretto / inverso). • Possibilità di abilitare singolarmente il controllo dei due relè (Posizione OFF). • Regolazione soglie di C/K da 0.15 a 2.00. • Ritardo alla connessione delle capacità 1..60 sec. • Ritardo alla disconnessione delle capacità 1..60 sec. • Tempo di riconnessione fisso 60 sec. • Impostazione della configurazione del sistema: 3ph / 1ph. • Uscite a relè con contatto in scambio. • LED verde di segnalazione alimentazione e durata inibizione. • 1 LED rosso di segnalazione inserzione relè 1. • 1 LED rosso di segnalazione inserzione relè 2. WARNING! Carefully read the manual before the installation or use. ● This equipment is to be installed by qualified personnel, complying to current standards, to avoid damages or safety hazards. ● Remove the dangerous voltage from the product before any maintenance operation on it. ● Technical data and descriptions in the publication are accurate, to the best of our knowledge, but no liabilities for errors, omissions or contingencies arising therefrom are accepted. ●Products illustrated herein are subject to alteration and changes without prior notice. ● A circuit breaker must be included in the electrical installation of the building. It must be installed close by the equipment and within easy reach of the operator. It must be marked as the disconnecting device of the equipment: IEC /EN 61010-1 § 6.11.2.1 ● Fit the instrument in an enclosure or cabinet with minimum IP40 degree protection. ● Clean the instrument with a soft dry cloth, do not use abrasives, liquid detergents or solvents Description • The DCRM2 allows to control the reactive current of a plant, eliminating it from the total current drawn from the mains and correcting the cos-phi of the load to the best possible value. • It can control the connection of maximum 2 banks of capacitors. • Each one of the two capacitor banks can be individually enabled and its power can be set through a dedicated trimmer. • It is also possible to adjust the time for connection and disconnection of the capacitors, modifying the reaction speed of the system. • The device can be used both in single-phase and three-phase wiring. Characteristics • Connection by external CT with 5A secondary. • Automatic recognition of CT polarity (direct / reverse). • Capability to individually enable the control of the two relays (OFF position). • C/K threshold adjustment from 0.15 to 2.00. • Connection delay for the steps adjustable from1 to 60 sec. • Disconnection delay for the steps adjustable from1 to 60 sec. • Reconnection time fixed to 60sec. • Selectable wiring configuration 3ph / 1ph. • Output relays each with changeover contact. • Green LED indictor for power on and inhibition time. • Red LED indicator for C/K1 tripping relay. • Red LED indicator for C/K2 tripping relay.
