4/8

Notes:

4. When Fail Soft operation is detected, regulation sensing will switch from the "S" terminal to the VGO terminal.

5. This condition can happen when the connection between the battery and VGO or the output terminal of the generator is broken.

In this case the delay of 1.1 seconds is not required.
