Ask an expert some questions about the meanings of the letters related to PID in internal pumps
Thread Content
I’d like to ask some experts about PID issues. What does HS-A mean? Is it a manual startup code? Then what could A, P, and F represent later on? What do MRI-A, MRI-P, and MRI-F mean? What does SCC-P mean again?
HS-P is probably for starting and stopping the pump, MRI-P is likely an operation indicator, and SCC-P may be for frequency conversion control. I found that the drawing representation methods in many institutes are the same. You can take a look at the homepage image of the process; there may be corresponding icon explanations
Thank you, I’ve read the entire design document; there are no annotations, which is why I asked. Thank you
