Mains Failure Controllers AMF3.1 ENKO Electronic Control Systems - IZMIR / TURKIYE Automatic Mains Failure Controller for Gen -Sets AMF3.1 offers versatile control AMF3.1 is a full Automatic Mains Failure unit intended to be used for functions for single or multiple Gen-Set applications. The controller can be used with single or three phase mains systems. Generator/Mains applications. The unit is designed with high process power for versatile and accurate control of all Gen-Set functions. It controls 3 phase mains and single phase generator voltage and also monitors generator load Main features: 3 phase mains voltage single phase generator voltage and current measurement 2 LED displays for parameter value readouts 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 pa- 10 configurable i/o ports for engine and system controls rameters 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. Efficient and Versatile control for all GenSet applications Many of the control variables can be displayed as required. The analog sensor characteristics can be adjusted from the menu to fit any kind of sensor. There are altogether 10 i/o ports available, where each one can be independently configured via program menu. 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 power is also measured and recorded. The controller has intelligent builtin functions for many applications and also provides economical solutions for Diesel Generator control. AMF3.1 control module is optimized for enhanced applications, where customer demands are high and allows minimal solutions for all genset applications with high reliability. 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 Automatic, Manual and Test operation modes Full digital calibration of all analog measuring inputs Characteristic adaptation table for temperature and pressure sensors Small mechanical outline for minimal control applications PC INTERFACE FOR MONITORING AND SYSTEM PROGRAMMING CONFIGURABLE I/O PORTS FOR CUSTOMER SPECIFIC APPLICATIONS Additional features: TRUE RMS VOLTAGE AND CURRENT MEASUREMENTS 9-35Vdc @ 1W maximum power dissipation (12Vdc, relays off) Operating temperature: AC voltage measurement: Frequency measurement: 7 i/p and 3 o/p ports with relay contact (dry contact) Charge alternator excitation current: Measurement accuracy: Phase voltages: ±2% of scale, Frequency: ±0.1Hz System Outputs: Protection class: IP52 (front panel protection) WIDE OPERATING TEMP.

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. The configurable inputs and outputs can be programmed in order to adopt the controller to more specific applications. The controller is suitable for 12/24Vdc systems. For remote monitoring and programming, RS232/485 ModBus RTU protocol can be used. ENKO PRO-Link program is available for on-site programming of all configurable parameters AMF3.1 can be connected to suit many...
