Automation Q&A

  • Asked September 24th, 2009

    I do not know of an industry definition. It is really more about the application of Good Engineering Practices. Fail-Safe systems are one method of mitigating risks as determined from my earlier post.
    Here are some examples:

    a. Duplication of sensing.
    b. Redundant sensing, different from above in that you use different methods of sensing.
    c. Sensor checking to verify on - off each cycle.
    d. Design the control system for fail to off (reject all).

    The Risk Assessment described in my earlier post will determine which steps to follow.
