Introduction -
 
Dynatek make ‘AMF CONTROLLER‘ is one of the most user friendly, Highly reliable & compact microcontroller based AMF Relay system. It is cost effective solution for AMF Controlling system. Most advanced technology is used to provide maximum features required for AMF Controlling system. It offers annunciation and controlling with Audio / Visual signal & potential free o/p contact. It works in Auto, Manual & Test mode
 
When AMF CONTROLLER is in Auto Mode, it continuously scans the mains supply. If Mains supply fails for specific period the controller starts cranking the DG set through start relay. Controller undertakes the set attempts. In case if it fails to start the DG after the set attempt it annunciates accordingly and turns ON hooter for Audio signaling.
 
If DG starts in any of the set attempt it allows DG to reach its operating speed to build up the required voltage and then it puts the load on DG by closing DG contactors automatically. On the resumption of healthy mains with required level of mains voltage controller connects the load on mains after the set delay periods & DG set is returned to standby mode for further operation after the required ideal running ( Cool - Off Delay).
 
In manual mode Controller does not react to Mains failure or Mains restoration. All the operations are to be done manually.
 
Controller is suitable for both 12V & 24V since it has wide operating voltage range ( 7 VDC to 30 VDC).
 
Low Battery -
 
The Controller is equipped with built - in circuit for sensing the battery Voltage. If the operating voltage goes below 8 V ( For 12V DC System) or 17 V ( For 24V DC System) , the controller indicates “LOW BATTERY” alarm. 
 
The Alarm Conditions -
 
1) Low Lub Oil Pressure
2) High Water Temperature
3) Over Speed 
4) Low Diesel level.
5) Oil temp. high
6) Low Battery
7) Engine fail to start
 
Various Time Delays -
 
1) Start Delay : After the Mains fail, the controller will wait for specific time to ensure the continuous failure of Mains before going for DG start - Up cycle.
2) Mains Return Delay : The controller will wait for specific time before putting the load from DG to Mains after the resumption of healthy Mains. 
3) DG Warm-up Delay : The system to allow DG to run idle for specific time before putting the load on DG.
4) DG Cooling Time : The system to allow the DG to run idle for specific time before  cut - off fuel supply to DG.
5) Crank On Time : The System allow the cranking for specific Seted time.
6) Crank Off Time : Silent timing bet’n two cranks.
