Cause : Multi-Function Input Selection 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 or Excludes “Not used” and “External Fault.”
2. Ensure all multi-function inputs are assigned to different functions.
3. Re-enter the multi-function settings to ensure this does not occur.
4. The Up command was set but the Down command was not, or vice versa (settings 10 vs. 11).
5. Properly set the functions that required for use in combination with other functions.
6. The Up 2 command was set but the Down 2 command was not, or vice versa.
7. Properly set the functions that required for use in combination with other functions.(settings 75 vs. 76).
8. Check if contradictory settings have simultaneously been assigned to the multi-function input terminals.
