ATS is Automatic Transfer Switch.
The function is to automatically change the supply from EB
to DG during power failure and again change the supply back
to EB from DG when the power restores.

AMF is Automatic Mains Failure.
The function is to automatically start the DG after a
specific delay when the power from EB fails.
