FUNZIONI

La presenza tensione è segnalata con il LED verde. Quando il segnale di misura supera il valore di soglia Y, viene attivato subito il LED rosso locale e dopo 1s anche il relè di uscita.

La ricaduta del relè avviene quando il segnale di misura è sceso sotto il valore di soglia Y - D (il differenziale D è una percentuale della soglia Y).

Il segnale positivo di misura, proveniente dal regolatore principale, deve essere collegato al terminale 6 (+) e riferito al terminale comune 4 (-) (Gnd).

All'interno del dispositivo è presente un ponticello A/C. Nella posizione A il relè si energizza al raggiungimento del valore impostato come sopra descritto; nella posizione C il funzionamento è contrario con il relè energizzato che ricade al raggiungimento del valore impostato.

FUNCTIONS

Voltage presence is signalled by relative green LED. When the measure signal passes the threshold value Y, the local red LED is immediately activated and, after 1 second, the outlet relay too.

The relay fall happens when the measure signal is below the threshold value Y-D (the differential D is a percentage of threshold Y).

The measure positive signal, coming from the main control, should be connected to terminal 6 (+) and referred to the common terminal 4 (-) (Gnd).

Within the device is located an A/C jumper.

When in position A the relay is energized when the set value is achieved as described above. When in position C the relay is always energized and when the set value is achieved the relay is deenergized.
