As shown in the figure: I would like to ask the experts about the meaning of the letters in the PID diagram. DRAFT: Mo3: Three hits? FMO: Thank you for getting back to me.

After consulting the expert “Zhi GE”, the answer is as follows: DRAFT: Negative pressure; Mo3: Three-out-of-three selection; FMO: Forced manual opening in case of a fault. Thank you, “Zhi GE”
