Hookup Diagram 

 

This configuration uses an external customer-supplied 12 or 24V battery to build the 
terminal voltage to a point that the automatic voltage regulator can take over and 
perform its function.  The ABF10 will automatically disconnect itself when the sensed 
voltage reaches approximately 10-15vac. 

 
Take special care to follow the wiring directions precisely!  DO NOT use a battery 
voltage different from that marked on the ABF10 unit!  Severe damage to the 
ABF10 will result!

 

 

Note that the maximum input voltage to the ABF10 Automatic Battery Flash Unit 
is 240VAC!

  

DO NOT input 277VAC into the ABF10!

  Severe damage to the unit will 

result!  For use on 480V systems, either connect the unit to the winding center taps T7 
and T8 or use a 480-240V step-down transformer. 

 
 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 
 
 
 
 

 
 
 

 

 

Note 1:

  Customer-supplied battery and charging system.  

An isolated battery is strongly recommended!

 

 

Note 2:

  Flash-Enable switch.  

Should be open whenever the exciter is not operating

.  Rate at 28VDC, 10A or 

greater.  Switch may be a switched B+, oil-pressure switch, or pushbutton switch. 

 

Note 3:

  If Using the ABF10 on a 480V or higher generator, connect terminals 1 and 2 to the center taps of the stator 

leads T7 and T8, or use a step-down transformer as appropriate to supply 240vac to the ABF10.   

   

DO NOT FUSE SENSING LEADS!!! 

 

Note 4:  

Connect battery positive to “12” or 24” terminals for 12V or 24V battery applications
