Auto Man Failure panel is normally connected to the generator set to control the generator set function. It can call the generator set if the AMF further connected to the Main Switch Board (received power from the other source - normally from the local authority) which equipped with auto transfer switch/automatic changeover contactor. While normal supply serve to main switch board failed, the AMF board will send the power failure signal to generator set. Then the generator set will run and serve the supply to main switch board.
