Cause : Differential Feedback Exceeded comes when the difference between the PID Feedback and Differential Level Source [H3-xx = 2D] is more than the level set in Y4-18 [Pre-Charge Loss of Prime Level 2] for the time set in Y4-19 [Differential Lvl Detection Time].
- Replace the feedback transducer or transducers.
- Set Y4-18 and Y4-19 correctly.
