This is the interlock and logic designed by the manufacturer. You can choose which ones to invest in – focus on the important ones and ignore the less significant ones; too many interconnections aren’t a good thing.

Firstly, for the pulp production process, there are several process interlocks: low low coal feed rate, low low water feed rate, high high liquid level in the mill outlet tank, mill motor tripping, and clutch disengagement – these five factors can cause the mill unit to stop operating. Secondly, for the coal grinder itself, the factors that can cause it to shut down include: low low low pressure oil flow, low low instrument air pressure, high high temperature of the coal grinder’s ear bearings, high high temperature of its small bearings, and high high temperature of its motor ； Third, the coal grinder will not be able to start if the following conditions are met: low low instrument air pressure, low low high-pressure oil pressure, low low low-pressure oil flow rate, high high temperatures of the ear bearings and small bearings, and high motor temperature. Generally, 90% are the same; some manufacturers may add additional interlocks, all of which serve to protect the equipment.

It seems that the mill’s main motor coil temperature triggers a shutdown at 65 degrees; this value is too low. It appears that the coil can operate safely even at 120 degrees

The second floor is amazing. I was wondering: in addition to instruments, do these interlocks also have electrical components? How do I separate them?
