● Hold enheden og kabler på afstand af kraftige elektromagnetiske felter.
● Brug skærmede kabler for at garantere alle specifikationer i henhold til HART.
● Tilslut en belastningsmodstand på mindst 230 Ω i serier i signalkredsløbet for at sikre fejlfri HART kommunikation. Når der anvendes strømforsyningsisolatorer til SITRANS HART transmittere, er der allerede installeret en
belasningsmodstand i enheden.
ADVARSEL
Forkert ibrugtagning i farlige områder Fejl på enheden eller fare for eksplosion i farlige områder.
● Tag ikke enheden i brug, før den er komplet monteret og tilsluttet i overensstemmelse med informationerne under de
tekniske data i betjeningsvejledningen.
● Før ibrugtagning skal du være opmærksom på effekten på andre enheder i systemet
ADVARSEL
Ibrugtagning og betjening med verserende fejl
Hvis der fremkommer en fejlmeddelelse, kan der ikke længere garanteres korrekt betjening.
● Undersøg alvorligheden af fejlen.
● Ret fejlen.
● Hvis fejlen stadig er der: – Tag enheden ud af brug. – Forhindr ibrugtagning.
