AMF controller wiring diagram

This is the typical connection wiring diagram of the BeK3 AMF controller. Despite the fact that you can connect the current transformers closer to the generator, we recommend that you connect the current transformers after the mains and generator changeover breakers. This will allow you to read the current when the load is connected to the power utility. You can set a warning or a shutdown limit for the current. In this case the BeK3 will activate the alarm only when the load is supplied by the generator. We recommend to use contactors with mechanical interlock. This solution will avoid back-feeding in case of troubles of the controller or the driver relays. 

The BeK3 has a special circuit to supply the coils of the relays. This helps to hold the relays during crank. You are required to use automotive relay rated at 12Vdc in case the engine has a 12V battery. When using a 24V battery, you are required to use 24V rated automotive relays.
