Found ILTANK Element #23 off scan since 03-Oct-2024. Although this defeat references Element #23 (Temperature warn) as alternate protection, the alternate protection is actually HESW Spill TC #2, which is active and on scan.

Scan re-enabled itself sometime after being taken off scan. Scan re-defeated.
