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.
