Page 2: Introduction
The DCRG8F automatic power factor controller has been designed incorporating the state of the art in the functions required for dynamic power factor correction applications. Made with a dedicated housing of extremely compact dimensions, DCRG8F combines a modern front panel design with practical fitting and the possibility of expansion at the back, where modules of the EXP series can be housed. The LCD graphic display permits a clear and intuitive user interface. -
Page 3: Operating Modes
OPERATING MODES The correctly selected mode is displayed in reverse at the centre of the home page. There are three possible operating modes, listed below: TEST Mode – When the controller is brand new and has never been programmed, it automatically enters in TEST mode that allows the installer to manually activate the individual outputs, so the correct wiring of the panel can be checked. -
Page 4: Display Page Navigation
FRONT BUTTON LOCK The front buttons can be locked to prevent involuntary access to the pages of DCRG8F. To enable the button lock, go to the main page and then, holding down the ◄ button, press the L button three times then the M button twice. -

Page 6: Waveform Page
– The graph is automatically updated about every second. EXPANDABILITY – Thanks to the expansion bus, DCRG8F can be expanded with additional modules of the EXP series. – It is possible to connect a maximum of 4 EXP… modules at the same time. -
Page 7: Additional Resources
– The two channels can communicate at the same time. – By activating the Gateway function, it is possible to have a DCRG8F equipped with an Ethernet port and a RS485 port which works as a “bridge” towards the other devices provided with the RS485 port only, and so obtain a saving (one Ethernet access point only). -
Page 8: Limit Thresholds
– These are variables which status can be modified by the user through the communication protocol and that can be used in combination with outputs. – Example: using a remote variable (REMx) as a source for an output (OUTx), it will be possible to freely energise or de-energise one relay through the supervision software. This would allow the use of DCRG8F outputs to control loads, e.g. -
Page 9: Ir Programming Port
In addition is necessary to set a different step number on every DCTL thyristor module, which must be equal to the step number set on the DRG8F regulator (e.g.: if I have configured on DCRG8F the step 3 as “Static-... -
Page 10: Parameter Setting Through Pc
PARAMETER SETTING (SETUP) WITH PC – Xpress configuration and remote control software can be used to transfer parameters (previously set) from the DCRG8F to a PC hard disk and vice versa. – Parameter transfer from a PC to the DCRG8F may be partial, i.e. only the parameters of specified menus will be transferred. -
Page 11: Parameter Tables
– If the user does not press any key for more than 2 minutes, the system leaves the setup automatically and goes back to normal viewing without saving the changes done on parameters. – Remember that, solely for the setup data that can be edited using the buttons, a backup copy can be made in the DCRG8F’s EEPROM. This data can be restored, when necessary, in the work memory. The data backup copy and restore commands can be found in the commands menu. - Page 12 M02 - GENERAL Default Range P02.01 CT primary OFF/1-30000 P02.02 CT secondary 1 / 5 P02.03 Type of plant installation Three-ph Three-phase Single phase P02.04 Current reading phase L1 / L2 / L3 L1-L2-L3 P02.05 CT polarity Aut - Dir - Rev P02.06 Voltage reading phase L1-L2...

– With this configuration is possible to monitor from the display of DCRG8F controller the status and the measures of each DCTL thyristor module. – Note. The EXP1012 mounted on DCRG8F controller is dedicated for the command of DCTL thyristor modules. If necessary to connect the DCRG8F controller to a supervision system (e.g. a PC) is necessary to add another communication expansion module, at choice between the codes compatible with DCRG8F (in the wiring diagram above is shown as example another RS485 module EXP1012). -

Page 27: Introduzione
Il regolatore automatico del fattore di potenza DCRG8F è stato progettato incorporando lo stato dell’arte delle funzioni richieste per le applicazioni di rifasamento dinamico. Realizzato con un contenitore dedicato, di dimensioni estremamente compatte, DCRG8F unisce il moderno design del frontale alla praticità di montaggio e alla possibilità di espansione sul retro, dove è possibile alloggiare moduli della serie EXP. Il display grafico LCD consente una interfaccia utente chiara ed intuitiva. -
Page 28: Modi Operativi
MODI OPERATIVI Il modo operativo selezionato correntemente è visualizzato in negativo al centro della pagina principale. Esistono tre possibili modi operativi, elencati di seguito: Modo TEST – Quando l’apparecchio é nuovo di fabbrica e non è mai stato programmato, entra automaticamente nel modo TEST che consente all’installatore di attivare manualmente le singole uscite, in modo da poter verificare la correttezza del cablaggio del quadro. -

BLOCCO TASTI FRONTALI E possibile inserire il blocco dei tasti frontali per evitare accessi involari alle pagine di DCRG8F. Per abilitare il blocco dei tasti bisogna posizionarsi sulla pagina principale e successivamente, tendendo premuto il tasto ◄, premere tre volte il tasto L e successivamente per 2 volte il tasto M. Sul display tramite una finestra pop-up verrà notificato l'avvenuto blocco dei tasti. Eseguire la stessa procedura per lo sblocco. -

PAGINA FORME D’ONDA – Questa pagina rappresenta graficamente la forma d’onda dei segnali di tensione e di corrente letti da DCRG8F. – E’ possibile vedere una fase per volta, selezionandola con i tasti ◄ e ►. – La scala verticale (ampiezza) è regolata automaticamente in modo da visualizzare al meglio possibile il segnale. -
Page 32: Risorse Aggiuntive
– I canali di comunicazione possono funzionare contemporaneamente. – Attivando la funzione Gateway, è possibile avere una DCRG8F equipaggiata con una porta Ethernet ed una porta RS485 che fa da “ponte” verso altri DCRG dotati della sola porta RS485, in modo da ottenere un risparmio (1 solo punto di accesso Ethernet). -

COMANDO MODULI A TIRISITORI SERIE DCTL VIA BUS RS485 Il regolatore DCRG8F, se utilizzato in abbinamento a moduli a tiristori Lovato serie DCTL, può comandare i moduli a tiristori tramite bus seriale RS485. Rispetto al comando tramite uscite statiche, questa modalità, oltre a realizzare un cablaggio semplice e lineare su bus, consente di monitorare lo stato e le misure elettriche di ogni modulo a tiristori DCTL (es. -
Page 34: Porta Di Programmazione Ir
La porta COM numero n del regolatore DCRG8F è dedicata per il comando dei moduli a tiristori DCTL via bus RS485. In aggiunta è necessario impostare su ogni modulo a tiristori DCTL un nodo seriale differente, che deve corrispondere al numero dello step impostato sul regolatore DCRG8F (esempio: se configuro sulla DCRG8F lo step 3 come “Statico-485”, il corrispondente DCTL deve avere P01.04=3). -
Page 35: Impostazione Parametri Da Pc
IMPOSTAZIONE PARAMETRI DA PC – Mediante il software di configurazione e controllo remoto Xpress è possibile effettuare il trasferimento dei parametri (precedentemente impostati) da DCRG8F al disco del PC e viceversa. – Il trasferimento dei parametri da PC a DCRG8F può essere parziale, cioè solo i parametri dei menù specificati. -

– Se non vengono premuti tasti per 2 minuti consecutivi, il menu setup viene abbandonato automaticamente e il sistema torna alla visualizzazione normale senza salvare i parametri. – Si rammenta che per i soli dati di setup modificabili da tastiera, è possibile fare una copia di sicurezza (backup) nella memoria eeprom di DCRG8F. Questi stessi dati all’occorrenza possono essere ripristinati (restore) nella memoria di lavoro. - Page 37 M02 - GENERALE Default Range P02.01 Primario TA OFF/1-30000 P02.02 Secondario TA 1 / 5 P02.03 Tipologia impianto Trifase Trifase / Monofase P02.04 Fase lettura correnti L1 / L2 / L3 / L1-L2-L3 P02.05 Verso collegamento TA Aut - Dir - Inv P02.06 Fase lettura tensioni L1-L2...
