Hello Everybody good day to all. i am facing a new problem in my newly buying sipart PS2 positioner(2wire and without HART) connected with DN25 size , 20mm stroke, single acting linear actuator(gland steam control valve). in both automatic and manual initializing mode its remains RUN4 for longtime.only some frequent actuator movement(30% movement then return to zero) there after a while , its not going to RUN 5 or Finish. air supply is 5.0KG/Sq.Cm, and 4ma input however during initializing in RUN1 its travel 100% movement . the existing valve made by ARCA regler, Germany and using only for 01 year.no visual air leakage there.using old existing positioner the valve open/close 100%.due to some problem of old existing positioner we are going to replace by new one. anyone here who can kindly advice me please. Thanks, Engr.Nizamul ------------------------------------------------------------------------------------------ |
