Components of interlock control
Thread Content
For example, a temperature interlock is composed of a temperature transmitter, a temperature controller, solenoid valves, etc.; a pressure interlock is made up of a pressure transmitter, a pressure controller, control valves, etc. It’s quite simple. So why, when we carry out technical upgrades and add more interlocks, do the process engineers and instrument technicians keep shifting responsibility to each other? Is that that difficult?
A car has four wheels, as well as steel plates, an engine, etc. Why don’t you buy one and assemble it yourself to drive?
Interlocks should be installed according to process requirements; more is not necessarily better.
The plant stops as soon as a interlock is triggered, and whether this interlock is caused by process issues or instrumentation problems, no one can avoid the consequences! ! ! If it wasn’t included in the original design and was added later, who would be willing to take responsibility for that! But this technological upgrade should be proposed by the process and equipment teams!

A workshop proposed a change; after discussion, a change approval document was prepared, and the instrumentation team was responsible for developing the interlocks, carrying out debugging, and putting them into use.
How to interlock this requirement is usually determined by the process team
The purpose of interlocking requirements should not be specified by the process. If you don’t ask someone to carry it for you, definitely no one will do it

Shifting responsibility in terms of processes is done because there’s no benefit, but you hold a high position... Shifting responsibility regarding instruments is done because it adds more trouble, but you hold a high position...
Otherwise... who diaoni
