Regarding intelligent positioners
Thread Content
What are the structural differences between intelligent positioners and ordinary electrical positioners? One of our smart positioners experiences intermittent power loss; that is, the valve suddenly closes completely. Upon on-site inspection, the LCD screen of the positioner shows no display, and the voltage measured with a multimeter is normal, yet the positioner fails to receive power. Then it suddenly works again, and this repeats several times, with it being functional most of the time. Since this valve is quite important, it has to be manually turned to the fully open position. I hope someone experienced can help analyze it. Thank you
Intelligent comparison is not easy to handle, as it involves modular components. It fluctuates in performance; there are soft faults, and it’s difficult to diagnose. If there are spare parts, try the replacement method.
The locator has also broken; intermittent power outages are one thing, but this is another. Has the circuit been checked in its entirety?
Smart locators are definitely very useful, but of course there is a chance of failures! It is recommended to use products from reputable manufacturers such as Siemens, FISHER, Yamaki, and SAMSON during use.
Smart locators are easy to calibrate; it’s not difficult to check them if there are any problems； It’s entirely modular in design, so it’s generally difficult to identify where the problem lies ； It can only be replaced. .
