Paul,
Field Engineer came in around Nov 29th 11:30 AM. He thought the issue was due to the connector within the AOP which model is apparently known for getting sensible to noise interferences. He replaced it with another model he brought, and left.
UNFORTUNATELY this didn't helped ! @Paul What's the next step please ?
