Mains Failure Controllers AMF3.4 ENKO Electronic Control Systems - IZMIR / TURKIYE Automatic Mains Failure Controller for Gen -Sets AMF3.4 is designed with high de- AMF3.4 is a full Automatic Mains Failure unit intended to be used for manding applications in mind. Highly flexible menu offers very Mains and Gen-Set control, where high process power is required. The controller can be used with single or three phase mains and gen- specific applications for the user. erator systems. 3 phase mains and 3 phase generator voltages are measured in true RMS and also 3 phase generator load current is measured. Phase sequence and Reverse Power Protection is provided for the Generator. User can program any of the auxiliary i/o ports for custom applications. The menu offers extensive control for each i/o and all the parameters can be configured via PC, using the ENKO PRO-Link configuration program. All the parameters can also be configured from the front panel controls. SMS messages can be sent, using optional GSM interface module. The unit can be programmed from remote distance. Many of the control variables can be displayed as required on the front panel. There are 3 analog sensor inputs available and character- Flexible control of Gen-Sets with intelligent system management and Real-Time clock Real time clock function allows the user to program weekly patterns for the generator operation. Time stamped alarm logging is also istics can be adjusted from the menu to fit any type of sensor. There are altogether 13 i/o ports available, among which many can be configured by the user. Load power is also measured and can be used with dedicated functions in the menu. Decisions can be made depending on active and/or reactive power of the load. Total accumulated active/reactive power is also measured and recorded. The real-time clock allows weekly and/or monthly generator control programs to be made, which can manage periodic test run and /or disabling the generator at certain hours or on specific days. Magnetic pick-up input is available for reliable and accurate measurement and control of engine speed. Main features: 3 ph mains voltage, 3 ph generator voltage and current measurement 3 LED displays for variable readouts and programming 13 configurable i/o ports for engine and system controls Measurement of active/ reactive load power and PF Full LED indicators for alarm and status conditions Independent control of MCB and GCB from front panel Phase sequence and Reverse Power protection for Gen-Set Full digital calibration of all analog measuring inputs Characteristic adaptation table for temperature and pressure sensors Daily or weekly control patterns for the generator, Automatic test run mode available for professional user.

APPLICATION CONNECTION DIAGRAM Typical connection diagram is shown and this is one of possible applications among many. The system is shown in 3 phase connection but can also be applied for single phase systems. AMF3.4 controller plastic housing is Mechanical dimensions designed according to DIN norms. Mechanical dimensions are shown in the drawing. Plastic housing is made of ABS (with added fiber) which provides high temperature resistance and good mechanical stability. The electrical order to adopt the controller to more specific applications. Magnetic pick-up can be used for rpm...
