FUNZIONI

Collegamento "A":

L'apparecchio regola la tensione di uscita (alimentazione ven- tilatore) proporzionalmente al segnale di ingresso 0⎟10Vdc. Valori fissi di intervento:

2,8V minima tensione erogata = 80Vac

10V massima tensione erogata = 230Vac I potenziometri P1 e P2 non sono utilizzati.

Collegamento "B":

L'apparecchio è pilotato da un segnale 0⎟10V proveniente da un potenziometro esterno da 4,7KΩ collegato ad una resistenza da 4,7kΩ.

Collegamento "C":

L'apparecchio è pilotato da un segnale 4 ⎟ 20mA prove- niente da un sensore di pressione esterno da 3000kPa. Con i potenziometri P1 e P2, è possibile regolare la minima tensione erogata (P1) e la massima (P2).

Set di fabbrica:

P1 = 11,5 mA = 1400kPa

P2 = 13,6 mA = 1700 kPa

230Vac ±15% - 50/60Hz 2kV (RMS)

FUNCTIONS

"A" connection:

The device regulates the output voltage (fan motor feeding) proportionally to the 0⎟10Vdc analogic input signal. Fixed values of intervention:

2,8V minimum voltage output = 80Vac

10V maximum voltage output = 230Vac The P1 and P2 potentiometers are not used

"B" connection:

The device is driven with a 0⎟10V signal coming from a 4,7kΩ external potentiometer connected to a 4,7kΩ resist- ance.

"C" connection:

The device is driven with a 4⎟20mA signal coming from a 3000kPa external pressure sensor.

With the P1 and P2 potentiometers it is possible to set the minimum voltage output (P1) and the maximum one(P2). Factory set:

P1 = 11,5 mA = 1400kPa

P2 = 13,6 mA = 1700kPa
