PO PROTECTION OPEN/ON RO RELEASE OPEN/ON RF RELEASE CLOSE/OFF PF PROTECTION CLOSE/OFF FBO FEEDBACK OPEN/ON FBF FEEDBACK CLOSE/OFF Protection enabled: Exhaust valve open; Exhaust valve closed. Protection disabled: Feedback enabled; Feedback disabled. Feedback is valid. Could someone please help me check if my translation is correct? Please point out any mistakes. Thank you. What is the difference between Open and on? What is the difference between close and off? Thank you all, experts. I’m a beginner and hardly have any ability to make judgments; please those who are not sure not to speak up. Thank you
As I understand it, on and off are used for logic 1 or 0, while open and close are used to indicate the on/off state of devices, depending on the context
