Chain system logic diagram
Thread Content
How can I understand the logic diagram of a vaporization chain system? What do \"excited\" and \"unexcited\" mean above? Thank you! ! !
The process of generating a rotating magnetic field in the generator rotor based on the principle of electromagnetic induction is called excitation
Excitation means being charged and exerting an effect; no excitation means no effect at all
Hehe, please give me some guidance regarding instrumentation – I don’t understand it either.
Consider the interlock logic explanations, process descriptions, and P&ID together. This post was last edited by xuqinger on 2009-3-6 at 19:20.]
According to the design specifications provided by the design institute, excitation means the device is powered on, while no excitation means it is not powered on; generally, it is designed to be in the excited state. It should be noted that some valves are designed to close when excited and to open when not excited; special attention must be paid to this.

Agree, ZhuZhu2009 :)
