Product fetures Principle of opertion Converter for sensors Prmeterisle ctutors Simple direct mounting Mnul override High functionl reliility Adjustle ngle of rottion Home position Conventionl opertion: he ctutor is connected with stndrd modulting signl of DC 0...10V nd trvels to the position defined y the positioning signl. Mesuring voltge serves for the electricl disply of the vlve position 0...100% nd s slve control signl for other ctutors. Opertion on the -Bus: he ctutor receives its digitl positioning signl from the higher level controller vi the -Bus nd trvels to the position defined. Connection serves s communiction interfce nd does not supply n nlogue mesuring voltge. Connection option for sensor (pssive or ctive sensor or switching contct). he ctutor serves s n nlogue/digitl converter for the trnsmission of the sensor signl vi -Bus to the higher level system. he fctory settings cover the most common pplictions. Input nd output signls nd other prmeters cn e ltered with the PC-ool MF-P or with the Service tool ZH E. Strightforwrd direct mounting on the ll vlve with only one centrl screw. he ssemly tool is integrted in the plug-in position indiction. he mounting orienttion in reltion to the ll vlve cn e selected in 90 steps. Mnul override with push-utton possile (the ger is disengged for s long s the utton is pressed or remins locked). he ctutor is overlod protected, requires no limit switches nd utomticlly stops when the end stop is reched. Adjustle ngle of rottion with mechnicl end stops. he first time the supply voltge is switched on, i.e. t the time of commissioning, the ctutor crries out n dption, which is when the operting rnge nd position feedck djust themselves to the mechnicl setting rnge. he ctutor then moves into the position defined y the positioning signl.
