AMF 3.1 USER MANUAL 

General Descriptions 

  

AMF 3.1 is a microprocessor-based controller, which monitors single or 3 phase Mains voltage, transfers 

the load between the Mains and the Generator and checks for system failures. The unit eliminates the need of 

common panel indicators, hence reduces the cost of the Generator panel. AMF 3.1 has 3 operation modes, which 

are Automatic, Test and Off modes. The desired operation mode can be set via the buttons located on the front 

panel. By pressing the Menu button for 3 seconds, the user can edit and save any parameter among the 425 

parameters in the unit. This feature allows AMF 3.1 to be easily adapted to any engine without the need of a 

separate unit.
