During a recent maintenance upgrade at a petrochemical refining complex, technicians experienced intermittent controller reboots on an AFV30D field control unit. Initial diagnostics pointed toward a failing power rail, but our technical team discovered that an unbalanced load across the 5.1V logic rail and unshielded AC distribution lines caused premature thermal stress.
