This diagram shows the motor operation status signals displayed on the DCS. What do XL, HS, and Fa mean?

It’s unclear regarding FA； HS is a switch signal; sometimes it indicates a manual switch, and its exact meaning should be specified on the P&ID homepage ； XL indicates the operating status display ； https://bbs.hcbbs.com/thread-819732-1-1.html] Previous posts on this topic

Isn’t every PID diagram supposed to have a cover page?
