AMF means auto mains failure panel, actuvally it is a watch
dog, it always monitor the AC input source, if there is any
failure or any abnormality in the input supply, immediately
it will disconnect the load from main source and change the
load path on generator and also it will send start signal
to gen set. when after resumtions of main AC supply it will
check the healthy ness of the supply if it is healthy then
with little time delay it will change over the load on main
source and also sends stop signal to the genset.
