NOTES:
1. Input Setting 1 can NOT be set to other than Function No.4. Cable is already connected between CN17
andTB3forInputSetting1.IncaseofusingInputSetting2,modicationofCN17connectorisrequired.
2. Function No.14 is valid only when applied to Input Setting 3.
3.Sameinput/outputfunctionsettingcannotbesettodifferentinput/outputterminals.
If set, a setting of larger function number becomes invalid.
Example:
When setting of input 1 and input 2 are same, input 2 will be invalid.
