Le transformateur de courant doit treimprativement install en amont de labatterie de condensateurs et des rcepteurs.Le paramtrage normal du rgulateur le rendinsensible au sens de rotation des phases etau sens de raccordement du transformateurde courant.Le rgulateur peut tre raccord de deuxmanires :c raccordement type PPLa mesure de tension est ralise entre deuxphases. La mesure du courant est ralise surune phase diffrente des deux phasesprcdemment utilises. Voir shmalectrique page 11.c raccordement type PNLa mesure de tension est ralise entre unephase et le neutre. La mesure du courant estralise partir de la mme phase.Voir shma lectrique page 11.

Attention : le type de raccordement utilisdoit tre cohrent avec le paramtrage durgulateur.

Sur un rseau de tension infrieure 110 V ousuprieure 415 V utiliser un transformateurpour alimenter les entres tension de mesuredu rgulateur. Ce transformateur utilis ne doitinduire quun dphasage minimum.

Attention en utilisation 4 quadrants(type RC12 seulement) la dtectionautomatique du sens de rotation desphases doit tre dsactive ( effectuerdans le mode paramtrage - voir chap. 7).Dans ce cas particulier il faut doncrespecter le sens de connexion du TC et lesens de rotation des phases .

Der Wandler mu so ins Kundennetzeingebaut werden, da die Stromrichtungdurch den Wandler entgegengesetzt zurKompensationsanlage ist.Keine Funktionsbeeintrchtigungenentstehen dem Regler durchPhasenvertauschung oder falschemWandleranschlu.Zwei Anschlumglichkeiten sindmglich:c Auenleiter-Auenleiter-AnschluDie Spannung wird zwischen zweiAuenleitern gemessen. Die Strommessungerfolgt in dem Auenleiter,der nicht zur Spannungsmessung genutztwird. Gem Anschluschema auf Seite 11.c Auenleiter-Nulleiter-AnschluDie Spannung wird zwischen dem Auen-und Nulleiter gemessen. Die Strommessungerfolgt im gleichen Pfad. GemAnschluschema auf Seite 11.

Achtung: Reglerprogrammierung- undanschlu mssen konform sein.

Fr den Reglerbetrieb in Netzen mitabweichenden Spannungsniveausgegenber den Standardbemessungs-spannungen unterhalb von 110 V oderoberhalb von 415 V werdenAnpassungstransformatoren bentigt.Achtung : Spezifikation derAnpassungstransformatoren fr denrichtigen Netzbetrieb auslegen.

Vorsicht: Bei Generatorbetrieb (RC12) mudie automatische Phasenrotationskennungdeaktiviert werden (im ProgrammReglerprogrammierung s. Kapitel 7)Hierbei sind Korrekturen der Phasenlageund der Wandlerpolaritt vorzunehmen.

The current transformer must be installedupstream of capacitor bank and loads.Standard programming of the controllermakes it insensitive to phase rotation andCT polarities.Two different connections may be used:c LL connection typeVoltage is measured between two phases.Current is measured from the phase that isnot used for voltage connection. Refer todrawings on page 11.c LN connection typeVoltage is measured between one phaseand neutral. Current is measured from thesame phase. Refer to drawings on page 11.

Warning: connection type used must bein conformity with programming ofcontroller.

On a network with a voltage below 110 V orabove 415 V use a transformer to connectcontroller voltage inputs. In such casetransformer specifications must include alimited phase variation.

Warning: on generator applications(type RC12 only) automatic detection ofphase rotation polarity must bede-activated (to be done in programmingmode - see chapter 7). In this particularcase phase rotation and CT polaritiesmust be correct.

El transformador de intensidad debe de estarobligatoriamente instalado aguas arriba de labatera de condensadores y de la carga.El regulador funciona correctamente sin teneren cuenta el sentido de rotacin de fases niel sentido de conexin del transformador deintensidad.El regulador se puede conectar de dosmaneras:c conexin tipo FFLa medida de tensin se realiza entre dos fases.La medida de intensidad debe tomarse de enuna fase distinta de las dos fases utilizadasanteriormente. Ver esquema elctrico pgina 11.c conexin tipo FNLa medida de tensin se realiza entre unafase y el neutro. La medida de intensidaddebe tomarse en la misma fase. Ver esquemaelctrico pgina 11.

Importante: el tipo de conexin utilizadadebe ser coherente con la programacindel regulador

En una red de tensin distinta de 220/240 V 380/415 V, utilizar un transformador paraalimentar las entradas de tensin del regulador.El transformador utilizado debe inducir un desfasemnimo.

Atencin: en utilizacin 4 cuadrantes (soloRC12) la deteccin automtica del sentidode rotacin de las fases debe ser desactivada(realizar en el men programacin - vercaptulo 7). En este caso en concreto sedebe respetar el sentido de conexin del TIy la rotacin de fases.

6 - commissioning settings (commissioning mode)Display shows "C/K SEARCH" and thecumulative number of first step connections.When a value is found display shows "OK"and the C/K value.If for reasons of important load variations thecontroller cannot find a proper C/K value"C/K SEARCH ERROR" appears on displayand C/K manual setting must be used.Automatic search of C/K can be stopped bypressing esc. , display then shows"C/K SEARCH STOP".

Manual setting of C/K on type R12 is digital(0...1.99).Examples of C/K calculationa) 400 V network, 500/5A CT,10 kvar first stepcurrent in first step:10000/400/e = 14.4 ACT ratio: K = 500/5 = 100C/K = 14.4/100 = 0.14b) 600 V network, 1500/5A CT,50 kvar first stepcurrent in first step:50000/600/e = 48.1ACT ratio: K = 1500/5 = 300C/K = 48.1/300 = 0.16

Manual setting of response currents on typeRC12 may allow you to define two differentconnection and disconnection thresholds(setting of inductive and capacitive values).This makes it possible to adapt theregulation curve to specific applications.Examples: no overcompensation, minimumcos f guaranteed.

Warning: the sum of the two responsecurrent values must be at least 2 timesthe true C/K value to avoid regulationunstability which would lead to contactorhunting.

Standard settings:inductive value = capacitive value = C/K.

Warning: both values must be entered.

c CT ratio setting (type RC12)digital setting from 100/5 to 3000/5.c manual overrideThis makes possible manual stepconnection and disconnection. After fiveminutes the controller comes back toautomatic regulation. Connection anddisconnection order depends on theregulation program selected. Connectiondelay depends on the programmed delaybetween successive connections of samestep.c interface languageThe interface language can be selectedbetween the following options: english,french, german, spanish or finnish.

Commissioning settings are done in thecommissioning mode which may be enteredfrom the measurement mode by pressing for 2s. The commissioning mode isdefined on the display by symbol " ".

c target cos fffff settingdigital setting from 0.80 inductive to 0.90capacitive.c setting of C/K or response currentsThe C/K value defines the reactive currentthreshold from which the controller connectsone step. It equals value of current in thefirst step divided by ratio of primary andsecondary currents of the currenttransformer. Hence it does not take accountof values of other steps.The C/K value can be automaticallysearched ("C/K AUTO" field) or manually set("C/K MAN." field on type R12 and"RESP VALUES" field on type R12).Automatic search of C/K takes between2 and 8 minutes: the controller connectsthen disconnects the first step several timesand measures the network reactive powervariation.

Use keys and tochange values. Enter and view the next stepby pressing ent. .

Pressing will reset the memoryincluding results of connections /disconnections used to detect steps withreduced power. This is required if stepvalues have been modified. Pressingwill avoid such reset.c step configuration (DOL setup) AUTO(type RC12)Each step of the capacitor bank may beprogrammed in one of the three followingoptions:v fixed step (1),v step not used in regulation (0),v normal step (AUTO).All steps must be viewed.
