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 ok there. Interesting matter is, if i place old existing positioner there then it easily move the actuator after pressing (+) and (- ) key in P85, 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?

I appreciating you if you  advice me kindly please to fix this problem.
