Automatic Mains Failure panels are installed as part of an automatic generator installation. The AMF is connected to the generator set to power control the operational functions. Once a power cut is detected, it automatically signals the generator to start and support the load.
It will also start the generator if it detects that the mains power fluctuates. These are ‘out of pre-set tolerances’ instances, for example power dips.
When the AMF panel detects that the mains has failed or is outside of tolerance, it will send a start signal to the generator to fire up.
Once the generator is ready to accept the load, the motorised switches or contactors within the AMF panel will switch the building load from mains supply to generator. This all happens automatically.
When the mains Gird supply is restored, the opposite will happen. The sequence happens in reverse to place your building off the generator and back onto Grid supply.
The AMF panel will put the building load back on to the mains supply and then stop the generator, once it has performed its cool down process. The Generator cool down is usually pre-set to take 5 minutes. This is called the ‘run on’.
