MP2000 AIR CONDITIONERS

Sistema di controllo a microprocessore per condizionatori d'aria • Air conditioners microprocessor control system

RELÈ SEGNALAZIONE PRESENZA ACQUA - RC420

Il dispositivo è posizionato all'interno del quadro elettrico e, abbinato al sensore RC350 è in grado di rilevare la presen- za di liquidi fornendo un contatto di allarme libero da tensione.

Lo stato di presenza tensione è segnalato tramite il LED verde ed in condizione di assenza di allarme il relè è eccitato con il contatto chiuso. In caso di intervento il relè si diseccita aprendo il contatto segnalando l'intervento tramite il LED rosso. Questa condizione consente l'inter- vento dell'allarme anche in caso di mancanza di alimenta- zione o per guasto del dispositivo.

Con 1 sensore si consiglia la taratura a 2kΩ. Con 2 sensori si consiglia la taratura a 1,5kΩ.

WATER DETECTION RELAY - RC420

The device is placed in the electric box and, when in connection with the sensor RC350, is capable to detect presence of liquid giving an alarm on voltage free contact. The voltage presence status is given by a green LED and in case of lack of alarm the relay is energized with close contact. In case of alarm the relay de-energizes and open the contact signalling the intervention activating the red LED, this allows to give an alarm indication also in case of not feed or faulty device.

With 1 sensor we suggest you to set the device to 2kΩ. With 2 sensors we suggest you to set the device to 1,5kΩ.
