What are the criteria for determining the quality of Siemens piezoelectric valves? Is it the coil resistance or?
Based on our experience, it is not possible to make a precise quantitative assessment. As long as the locator passes its normal self-checks and there are no leaks in the gas supply and other related issues, if the valve position still experiences oscillations or slight fluctuations, the amplifier should be replaced
There was no problem originally! Recently, the smart positioners keep breaking down:(Helpless
If the Siemens PS units that have been newly installed are breaking down frequently, first examine their characteristics, then analyze the factors present at the installation site – identify all the factors that could cause such problems and check them one by one.
