Hello Sir, Have a good day. I have recently facing problem in a newly buying Siemens PS2(2wire, 4-20ma, 2 wire, without HART) smart positioner connect with my existing Single acting, air to open linear actuator(pneumatic control valve) having 20mm stroke when I am going to newly calibation. During commissioning this new positioner with existing control valve/actuator in initial condition its display shows P 85 and NOINI mode, at that time when if i press (+) and (-) button then the actuatortotally doesn’t not move. only small clicking sound hearing inside the positioner and little air Release from actuating pressure line(Y1) of positioner , however pneumatic(4kg air pressure) and electrical(4ma , 24VDc) connection is there. Interesting is if i place old existing positioner there then it easily move the actuator after pressing (+) and (- ) key in NOINI mode. Is there any problem of lever setting or restrictor setting there.i don’t change any restrictor setting in this newly buying positioner during commissioning there. i am confused if there any setting required in restrictor at positioner during newly commissioning? Anybody here who can advice me kindly please to fix this problem. ------------------------------------------------------------------------------------------ |

Closed cause question posted twice. The second thread with the subject SIPART PS2: cannot move existing actuator at all is published within the conference Process Instrumentation / Analytics / Weighing Systems SIWAREX.
