Alternator #1 Temperature Threshold.

 

Controls the setpoint at which point field current is 

reduced when the the alternator temperature sensor indicates an over-temp condition at the alter-

nator. Requires temperature sensor installation. Preset at 108

˚

.

Absorption Voltage.

 

Controls the maximum limit of allowable bulk voltage. Starts at value set 

by battery program currently in use. Adjustment spans from 13.5 to 14.8 volts. To reverse direction 

of scroll, release magnet and wait for LED to display Av code. Re-activate switch with magnet and 

release when desired value is indicated.

Float Voltage.

 

Controls the maximum limit of allowable float voltage. Starts at value set by bat-

tery program currently in use. Adjustment spans from 13.0 to 13.8 volts. To reverse direction of 

scroll, release magnet and wait for LED to display Fv code. Re-activate switch with magnet and 

release when desired value is indicated.

Absorption Time.

 

Controls the minimum time period for non-calculated absorption charging. 

Standard  value  set  by  battery  program  selected. Adjustment  spans  in  tenths  of  hours  from  12 

minutes to six hours. To reverse direction of scroll, release magnet and wait for LED to display a1c 

code. Re-activate switch with magnet and release when desired value is indicated.

Float Time.

 

Controls the minimum time period for non-calculated float charging. Standard value 

set by battery program selected. Adjustment spans in tenths of hours from 12 minutes to six hours. 

To reverse direction of scroll, release magnet and wait for LED to display F1c code. Re-activate 

switch with magnet and release when desired value is indicated.

Field Threshold - Float To Absorption .

 

Controls the criteria the regulator uses to deter-

mine how hard the alternator has to be working to stay in calculated absorption charging mode. 

Factory set at 67% field output. Raising “ffl” shortens “ffl” increases calculated absorption charge 

time. Adjusted in 1% increments. Span of adjustment is 16% to 96%. To reverse direction of scroll, 

release “ffl” code. Reactivate switch with magnet and release when desired value is indicated.

Field Threshold - Bulk To Absorption .

 

Controls the criteria the regulator uses to determine 

how hard the alternator has to be working to stay in calculated bulk charging mode. Factory set 

at 67% field output. Raising “fba” shortens calculated bulk charge time. Lower ing “fba” increases 

calculated bulk charge time. Adjusted in 1% increments. Span of adjustment is 16% to 96%. To re-

verse direction of scroll, release magnet and wait for LED to display “fba” code. Re-activate switch 

with magnet and release when desired value is indicated.

Slope Voltage Correction.

 

Adjusts the voltage (in milivolts) the regulator uses when moni-

toring battery temperature sensing. Can be custom adjusted to meet the needs of unique battery 

technologies. Consult with battery manufacturer for specific slope voltage recommendations.

Battery #1 Temperature Threshold.

 

Controls the setpoint at which point field current is dis-

continued when the the battery temperature sensor indicates an over-temp condition at battery #1. 

Requires temperature sensor installation. Preset at 52°C.
