Cause : Multi-Function Input Setting Error comes when a contradictory setting is assigned to multi-function contact inputs H1-01 to H1-07.

1. The same function is assigned to two multi-function inputs
2. Excludes “Not used” and “External Fault”
3. Ensure all multi-function inputs are assigned to different functions.
4. Re-enter the multi-function settings to ensure this does not occur.
