ESD trip problem
Thread Content
When ESD triggers a chain trip and the value that triggered the chain returns to normal, can ESD automatically restore the chain, or does it need to be restored manually?
Most of them must be reset manually. There is no manual recovery interlocking. There are a small number of work sections that can be restored directly (the design is older).
1. For example, equipment interlocks are generally equipped with SR triggers. Such interlocks must be manually reset before the interlock can be restored. 2. However, if there is an interlock such as high-pressure steam venting, the general design is high opening and low closing, and manual reset is not required. 3. Whether manual reset is required is designed based on the interlocking requirements, so it cannot be concluded universally. However, interlocking in the ESD generally requires manual reset.
