Which interlock sources generally need to be removed while driving?
What technology? Some chains automatically block it
The original poster is too lazy – clarify which processes determine which interlocks need to be bypassed temporarily!
Generally, those process interlocks whose interlock values fluctuate outside the low-low and high-high limit ranges during startup are removed, in order to prevent process parameters during startup from triggering interlock actions that could cause the plant to stop operating
You could talk about your manufacturing process first, and then we can discuss it further. In coal water slurry gasification, the mechanisms that could cause shutdowns during startup due to parameter changes are usually connected to bypass circuits; once operation is normal, all of these mechanisms must be put into use
It depends on the specific process and the conditions during testing; in my opinion, all possible interlocks should be implemented during the initial commissioning phase
