    Yes, I was aware of machine safety but was not aware of categories.
    so far what I dig out. is...

    CATEGORY 1: “A single fault can lead to the loss of safety function.”
    Example: A door switch contact failing in the closed position resulting in the machine continuing to run
    CATEGORY 2: “A single fault can lead to the loss of safety function and the loss of safety function shall be detected.”
    Example: A door switch contact failing in the closed position resulting in the machine continuing to run but a second door switch triggers a warning light.
    CATEGORY 3: “A single fault does not lead to the loss of safety function.”
    Example: a door switch contact failing in the closed position but a second door switch alerts a safe controller which shuts down the machine. The distinguishing detail from Category 4 is that there can be multiple switches used on each channel of the controller.
    CATEGORY 4: “An accumulation of safety faults does not lead to the loss of safety function.”
