Hi Shaga,
I hope you are doing well!
I am wondering if you have found the response to your question here:

"I have a question relate to the Hysys. fro example when pressure control is fail close it ..."

If so, could you please tell me how you ended up doing it,
Thanks!

Hi Neil, Cheng here. Sorry for bothering. It’s now 2025, and I’m still working on the settings for a SD14E relay. Similar to your post, I haven’t been able to find a manual for this relay. Would you be open to sharing any information you have on it? I’d really appreciate any help.
