Dear sir, have a good day. i have recently facing problem in a a newly buying Siemens PS2 positioner connect with existing Single acting linear actuator , 20mm stroke.during comissioning this new control valve/actuator in initial condition its display shows P 85 and NOINI mode, at that time when i press + and - button the actuator totally not move.only small sound hearing inside the positioner and some air release backside of positioner , however pneumatic and electrical connection is ok.if i place old existing positioner there then it easily move the actuator after pressing + and - key in NOINI mode. Moreover when i go in Log 5 ,NOINITM mode 30% open the valve in both YEND1 and YEND2 once i press both + and - key.once i release button then actuator go to zero condition.it doesn't hold at all. If its abnormal what can i do.would you please advice me. if i press only either + or - button then actuator not move in YEND1 and YEND2 mode.but when i press both + and - button simultaneously then it open actuator only 30% but not hold at all then when press hand button its display range message. will you please advice me its normal or abnormal? Really i am facing a horrible condition for this positioner at my site and i am apologetically wish to get you kind advice please. Thanking You, Engr.Nizamul hoq. proprietor.

u can use any positioner which having POT for feedback. so u can use PS2(6DR5120).
what is the value of pot meter i want to do in my plant please help me to do this
Positioner already having POT so why u need another POT....so u can use the same POT. If you want use any other POT then max 10k ohms POT u can use ..
Is the wiring of the potentiometer of the base positioner tapped to the remote positioner?
Yes ....
apni ki BangladeshiI?
there is no calibration done by a positioner. the positioner is long time to take to calibrate and show a error of u...d (
