FUNZIONI

Il dispositivo è dotato di LED verde per segnalazione presenza tensione e può controllare 2 carichi elettrici contemporaneamente (max 1,5A).

Con la misura di corrente maggiore della soglia minima di intervento, quindi in condizione di normale funzionamento, il relè è eccitato con il contatto di allarme chiuso. In caso di intervento si accende il LED rosso ed il relè si diseccita aprendo il contatto.

Questa condizione consente l'intervento dell'allarme an- che in caso di mancanza di alimentazione o per guasto del dispositivo.

I morsetti di alimentazione del dispositivo (1 - 2) si trovano sotto la scatola di contenimento.

FUNCTION

The device is equipped with a green LED to indicate voltage presence and can control two electric loads simultaneously (max 1,5A).

With measured current close to the minimum intervention threshold (normal working conditions) the relay is ener- gized and the relative contact is closed.

In case of intervention the red LED is on and the relay is deenergized with consequent opening of the contact. This working mode allows to have an alarm indication also in case of not energized or faulty device.

Feeding voltage terminals (1-2) are located under contain- ing box.
