Redundancy link chip failure

Series 2 redundant cards contain a microchip that enables redundancy. If the chip fails, the redundant cards stop communicating, and a switchover occurs instantaneously. To correct this issue:

1. Replace the faulty card.

2. Open DeltaV Diagnostics (click Start → DeltaV Operator → Diagnostics).

3. For each card, right-click the card, and then select Clear Saved Fault Information.
