Hi All, Thank you again for your responses about my DFMEA question they were very helpful.
I have another question about safety design. We are using an absence of voltage tester (AVT) that provides a UL approved method to open an enclosure without having to put on PPE and perform a live dead live test. We recently learned that a batch of these AVTs have an issue where in a specific scenario when power is off the AVT will indicate that it is unable to determine whether the enclosure is live or not. Two questions related to this: Does this make the AVT components that exhibit this error defective and unsafe? Since the AVT does not give incorrect information, (it is unable to determine the electrical state and reports this), and this only happens when there is no power on the AVT, I am wondering if we can just instruct our service personal to wear PPE and perform the live dead live test in these situations. Secondly, does this make the components from the problem batch but not exhibiting this behavior defective? In other words if an AVT exhibits this behavior on enclosure A but not B can we use it on enclosure B?
