Sistem automation yang aman dapat mencegah kecelakaan terjadi dan terjadi pada operation. Ladder logic adalah program komotif yang digunakan untuk menjelaskan interlocks.
Understanding Aman Interlock
Sistem perhubungan aman dan devices or syemt pencegahan mesin operasi faratring under unsafe conditions. They can bare moical, electrical, or electrononic. Inladder logic, saffy intersafy are applimente threogh specic antcalt conficutiontions.
Calculating Safety Interlock Requirements
Ini adalah kalkulation initifying potential berbahaya dan menentukan bahwa kebutuhan yang diperlukan untuk keselamatan.
- Assessing the machinery and esps risks
- Defining safety functions required for each varad
- Menentukan bahwa itu aman device response times
- Kalkulating the logic needed to actitate interlocks
