We are currently experiencing DCS (Honeywell TDC3000) hardware failures
during lightning storms. During these storms, we have seen failures of
analog input cards, HPM I/O link cards, as well as noise errors on the UCN
cables. We are evaluating the grounding (earthing) of our DCS system and are
wondering if anyone has experienced similar DCS failures? If so, do you have
any recommendations as to how to correct it.
Thanks,
