What does it mean in the red box?
Thread Content
Hello everyone, this relates to the temperature control and interlock systems of the reactor. I would like to ask what is meant by the content within the red box?
It seems to be a relatively independent control logic; when the temperature reaches H or HH, a certain action will be carried out.
Thank you. THS likely stands for temperature manual switch. In this process, the temperature needs to be adjusted every hour – does it mean that after setting the desired temperature, this device is used to send a signal every hour?
So H means manual? Can’t figure it out
