Need help with an English translation! How should this sentence in the PID diagram annotation, regarding instrument logic control, be translated into English?

As indicated in the PID diagram, note NOTE4: The annotation regarding this in the NOTES is: 2003 voting logic for low low pressure trip of instrument air distribution line. As shown in the figure below, I searched for translations of this phrase on three translation websites: Baidu, Youdao, and Google. However, the translations seemed quite incorrect: 1. Google Translate: Voting logic for low-pressure tripping of instrument piping lines in 2003. 2. Youdao Translation: Voting logic for low-pressure shutdown of instrument piping lines in 2003. 3. Baidu Translate: Voting logic for low-low pressure shutdown of instrument air piping lines in 2003. I would like to ask the experts here: How should the English phrase “2003 voting logic for low low pressure trip of instrument air distribution line” be translated?
The image is here! ! ! Does 2003 mean 3 taken to the power of 2? I don’t know much about valves; I’m really seeking advice! ! !
The original text should be 2oo3, not 2003; in automatic control, 2oo3 represents 3 taken modulo 2
Kudos for your attention to detail; those new to this industry might not notice such subtle issues, so you’re really lucky!
Logic for penalty 2oo3 in case of low instrument air pressure
This post was last edited by Ku Liang Zhi Le on 2020-7-1 12:03: the logic for triggering a low-low condition is based on the pressure in the instrument air distribution pipeline, with a 3-out-of-2 approach.
In general terms, PID relates to interlock logic; for unclear interlock logic, one should refer to the interlock logic diagram. Instruments are instruments, valves are valves, and control is control. Here, a two-out-of-three decision is made; what exactly is controlled depends on the interlock logic diagram
