Cause : AI parametrization - comes when the current/voltage hardware setting of an analog input does not correspond to parameter settings.

1. Check the event log for an auxiliary code.
2. The code identifies the analog input whose settings are in conflict.
3. Adjust parameter 12.15/ 12.25.

Note: Control board reboot (either by cycling the power or through parameter 96.08 Control board boot) is required to validate any changes in the hardware settings.
