Is there anyone who is skilled in operating the catalytic self-protection interlock?

Your description in words is a bit confusing.....:L 1. Once the device is actually activated, you’d better pray to stay safe and move as little as possible. Although it’s considered a form of training, things can go wrong, leading to further accidents and extra trouble. 2. During regular drills, it is possible to use on-site signs (for outdoor operations) ； Parameter control description (internal operation) ； Assessment is conducted on aspects such as the squad leader’s command. 3. I think you mean the interlock testing process before starting operation. This process is generally divided into static testing and dynamic testing; I won’t go into details here. There should be relevant information on the forum, so you can search for it there.

At the start of operation, there is a self-protection test phase, during which self-protection is triggered manually to check the operation of the respective self-protection valves

I’m sorry; I really didn’t explain it clearly enough. What I would like to know mainly includes: 1. How to interpret self-protection charts? For example, “What do trigger, R, and S mean?” “What do red wires and green wires mean?” ”2. After handling the self-protection trigger, how to reset it? Which button to press? 3. What are the specific steps for static and dynamic debugging at the start of operation? If there is relevant information, how should one search for it? There’s nothing I can do; I really haven’t used this thing before, so please give me some guidance. Thank you

I’m stunned – you don’t have a master to guide you! Go find Master Yang... And there should be detailed descriptions in your operating procedures.

The self-protection logic drawn in the DCS system may not be consistent with the description in the background 1001RS logic diagram. According to the self-protection logic diagram provided by the design institute, there are many instances of 1001, which are usually handled in the DCS backend. Some of the logic and results in the DCS interface involve inversion, which facilitates understanding. Triggers are similar to devices that output 0 or 1 when a condition is met. R denotes reset, while S denotes priority. The red and green lines are related to the drawing of the DCS logic diagrams; green indicates that no trigger has occurred, while red lines indicate that a trigger has taken place, meaning that the interlock conditions have been met. This makes it easier to immediately determine which condition has triggered the safety protection mechanism. Reset is typically achieved by using a reset button; the reset condition is met when the self-protection condition is lifted or removed, and self-protection is ceased once the result of the self-protection action matches the current state of the valve. Finally, it is best for the device not to engage in self-protection actions during production, but this can be studied. It is recommended that you get involved during the process self-protection testing before the installation starts; then you will understand.

Bro, you’re right too; I just want to hear what professionals have to say! Everything in the operating procedures was prepared by the production technology department; there’s not much of interest in it. I just want to understand the logic diagram! I posted it out of pure curiosity.

Thank you, it’s been very helpful! One more question: How should priority be understood for S?

This is much clearer than the logic diagrams of the NAND gate format that we learned back then; importantly, through these logic diagrams it is possible to understand the trigger conditions, the results after triggering, the reset conditions, and so on.
