AMF 4.0 AUTOMATIC MAINS FAILURE UNIT
AMF 4.0 genset control unit provides the functions, required in automatic mains failure
applications of gensets. It can be operated in automatic, test and manual modes. It contains
digital displays providing functions of all analog displays needed in generator panels. Device
digital displays show 3 phase mains and generator voltages, 3 phase generator currents, mains
and generator frequencies, battery voltage, oil pressure (bar), engine temperature and engine
hour. Generator is monitored constantly and when generator or mains values exceed the limits
adjusted in the parameter menu, necessary actions are taken and alarm is activated. Last ten
alarms are recorded in the device memory. All operating modes and timings can be adjusted
in the parameter menu. This flexibility is provided for different kinds of generator
applications.
