IL DIP SWITCH N.2 SELEZIONA
LA MODALITA’ DELL’USCITA IN
CORRENTE
DIP SWITCH N.2 SELECTS THE
CURRENT OUTPUT MODE
POSIZIONE “ON”: USCITA ANALOGICA PROPORZIONALE 4-20 mA CORRISPONDENTE ALLO 0-100%
DEL FONDO SCALA
“ON” POSITION: PROPORTIONAL ANALOG 4-20 mA OUTPUT CORRESPONDING TO 0-100% FULL SCALE
POSIZIONE “OFF”: USCITA DOPPIA SOGLIA 10-20 mA PER CENTRALI A VARIAZIONE DI ASSORBIMENTO
(LE SOGLIE OPERATIVE SONO LA 1 E LA 2).
“OFF” POSITION: 10-20 mA CURRENT OUTPUT TO OPERATE WITH FIRE CONTROL PANELS USING A
CURRENT/VOLTAGE CONVERSION (THE OPERATIVE THRESHOLDS ARE THE 1ST AND THE 2ND)
.
I VALORI SONO IN % DEL FONDO SCALA (RIL. OSSIGENO VALORI ASSOLUTI) /
VALUES IN % FULL SCALE (ABSOLUTE VALUES FOR OXYGEN)
USARE SOLO I DIP-SWITCH 3-4-5-6 PER IMPOSTARE LE SOGLIE DI ALLARME /
ONLY USE DIP SWITCHES 3-4-5-6 TO SET ALARM THRESHOLDS
(*) SOLO PER RILEVATORI DI ARRICCHIMENTO - DEFICIENZA DI OSSIGENO /
