Cause : Pri VelFdbk Loss comes when a feedback Loss has been detected for the source of P127 [Pri Vel Feedback]. The feedback loss could be due to a problem detected by the feedback option module selected by P125 [Pri Vel Fdbk Sel] or due to a loss in communication between the feedback option module and main control board.
- The source of primary velocity feedback must be configured not to fault if the feedback loss switchover feature is used.
