AMF Controller
AMF Controller
Dynatek offers an AMF Controller, AMF-02. This is an automatic mains failure module designed to protect and control the diesel generator. It uses advanced single chip microcontroller for an easy and trouble free DG set control. It uses a jumbo 16 x 2 LCD display for read out and membrane keypad for interaction with user for various parameter settings. It has data logging facility to check every event. Operation: this unit works in Auto/Manual mode. If mains supply is available the unit keeps the load on mains. In case of mains failure or under voltage, the AMF controller will be activated by internal 3-phase monitoring; if mains fail for entire start/delay period the crank cycle will be activated. The crank and rest period (interval between crank) and crank attempt are settable by user. When engine takes speed the internal GVM detects the voltage and also checks LLOP to make "NC" to "NO" to disconnect cranking. After the engine warm-up period is elapsed, load is switched over to the DG. When mains supply restores and persists for the entire restore delay time, the DG supply is disconnected after set time delay (settable interchange time delay) mains supply is connected. The engine runs idle without load in cooling time delay before shutdown. In the manual mode the engine Start/Stop, Mains/Gen Contactor On/Off can be done manually by push buttons. In periodic test mode the DG set can start for set duration on particular time and weekday. All the parameters like Day, Time and Duration are settable by user. The generator is protected against any generator related fault, i.e., LLOP, HWT, etc., in auto/manual and periodic test mode or any electrical fault like overload, mains or DG check back or low/high mains or DG voltage.
