REGOLATORE DI VELOCITÀ PER MOTORI TRIFA- SE - DVR

Il dispositivo è posizionato all'interno del quadro elettrico e trova la sua principale applicazione nel controllo della velocità di rotazione di ventilatori accoppiati a motori elet- trici trifase, tramite un segnale proporzionale 0⎟10Vdc.

FAN MOTOR SPEED CONTROLLER FOR THREE PHASE MOTORS - DVR

The device is placed in the electric box and it has been designed to control the rotation speed of the directly cou- pled three-phase fan motors, through a 0⎟10Vdc propor- tional signal.

FUNZIONI

P1: determina la minima tensione del segnale di comando. Impostare al minimo, tutto ruotato in senso antiorario. P2: determina il campo della tensione di comando. Con i ventilatori in funzione e il segnale a 10Vdc verificare che la tensione in uscita sia al massimo; eventualmente aumen- tare, ruotando in senso orario, fino al raggiungimento del valore (un incremento elevato restringe il campo di lavoro). P3: determina la minima tensione applicata ai ventilatori con il segnale di comando al minimo.

FUNCTIONS

P1: sets the minimum voltage of the command signal. Set to minimum, turning the knob fully counter-clockwise. P2: sets the voltage command signal range. With fans in working mode and the signal at 10 Vdc, check if the output voltage is maximum; if not turn P2 clockwise to get maxi- mum value (never try to increase the output voltage higher than input voltage).

P3: sets the minimum voltage for the fans with the com- mand signal at minimum value.
