Override control
Thread Content
Have you ever done the logical diagram for override control? Please provide it
The so-called override control, or selective control, allows for either low or high selection; in abnormal operating conditions, the abnormal-condition regulator takes over from the normal-condition regulator, and it returns to normal operation automatically once production resumes. It is important to note that measures should be in place to prevent integral saturation.
What was said upstairs is completely correct; I’m looking for a way to express it
Override control, also known as selective control, can be divided into three categories: on-off selection, continuous selection, and mixed selection. The components for on-off selection are switches (toggle switches, solenoid valves, etc.), while those for continuous selection are selectors (high-value selectors, low-value selectors). These control systems are represented on P&ID diagrams. I don’t know what logical drawing refers to ?
Mm-hmm, just mark low selection or high selection on the PID diagram, thanks upster :)
