When deployed in a fully redundant configuration, a single module can be extracted and inserted under power without interrupting the parallel SISNet channel. The active safety logic functions seamlessly via the surviving redundant media link.\u003c\/p\u003e\n\u003cp\u003eQ: How does the VS6002 respond if the optical signal level drops below the minimum receiver threshold?\u003c\/p\u003e\n\u003cp\u003eA: The card detects the attenuation variance instantly, sets a dedicated physical layer diagnostic flag, and flags a channel degradation status to the DeltaV diagnostic system while forcing the redundant safety loop to rely strictly on the primary or secondary peer channel.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFiber-Optic Bend Radius Constraints:\u003c\/strong\u003e Ensure all fiber-optic interconnect cables maintain a minimum mechanical bend radius specified by the cable manufacturer (typically 30 mm minimum) to prevent optical signal losses and physical fiber fatigue.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDIN-Rail Grounding Verification:\u003c\/strong\u003e Mount the assembly securely onto a standard grounded T-type DIN rail.
