MP2000 AIR CONDITIONERS

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

REGOLATORE DI VELOCITÀ PER MOTORI MONOFA- SE - RIV 1200

Il dispositivo è posizionato sul condensatore ad aria remoto e trova la sua principale applicazione nel controllo della velocità di rotazione di ventilatori accoppiati a motori elet- trici monofase, tramite un segnale proporzionale 0⎟10Vdc.

FAN MOTOR SPEED CONTROLLER FOR SINGLE PHASE MOTORS - RIV 1200

The device is placed on the remote air cooled condenser and it has been designed to control the rotation speed of the directly coupled single phase fan motors, through a 0⎟10Vdc proportional signal.

FUNZIONI

L'apparecchio regola la tensione di uscita (alimentazione ventilatore) proporzionalmente al segnale di ingresso 0⎟10Vdc proveniente dal condizionatore.

Valori fissi di intervento:

-con segnale da 0 a 2,2Vdc l'apparecchio è in stand-by

-con segnale da 2,2 a 2,8 Vdc l'apparecchio è nel campo di isteresi e non produce alcun effetto

-con segnale da 2,8 a 10Vdc l'apparecchio regola la tensione in uscita da 80 a 230Vac.

L'apparecchio è dotato di interruttore generale luminoso e di relè con contatto pulito in deviazione per segnalazione a distanza dello stato di allarme generale che comprende: termico ventilatore - interruzione connessione per posizio- ne off interruttore o mancanza alimentazione - motore guasto - errore Eprom - stadio di potenza guasto.

Il relè è attivo in condizioni di funzionamento normale e si disattiva in caso di presenza allarme o mancanza tensione. Pertanto si deve utilizzare il contatto del relè normalmente aperto (C-NO).

Non vengono utilizzati l'ingresso 4⎟10mA ed i relativi potenziometri di taratura P1 e P2.

FUNCTIONS

The device regulates the output voltage (fan motor feeding) proportionally to the 0⎟10Vdc analogic input signal coming from the air conditioner.

Fixed values of intervention:

-with signal from 0 to 2,2Vdc the device is in stand-by

-with signal from 2,2 to 2,8Vdc the device is in the hysteresis range and does not produce any effect

-with signal from 2,8 to 10Vdc the device regulates the output voltage from 80 to 230Vac.

The device is fitted with a lighting general switch and with a voltage free deviating contact for remotization of the general alarm status that includes: motor thermal protec- tion - connection interrupted for switch in off position or lack of feeding - fans motor fault - Eprom error - power fault.

The relay is active in normal working conditions and deac- tivates in case of alarm presence of lack of feeding.

For alarm remotization connect the normally open relay contact (C-NO)

The P1 and P2 calibration potentiometers and the 4⎟20mA inlet are not used.
