Alternator Temperature Threshold. Controls the setpoint at which point eld current is reduced
when the the alternator temperature sensor indicates an over-temp condition at the alternator. Requires
temperature sensor installation. Preset at 108˚.
Float Voltage. Controls the target voltage for oat stage. Adjustment spans from 26.0 to 27.6 volts.
Default is based on battery program selected. To reverse direction of scroll, release magnet and wait for
LED to display Fv code. Re-activate switch and release when desired value is indicated.
Float Time. Controls time setting for oat mode. Standard value set is 18 minutes. Settings are from 6
minutes to 12 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.
Amp Manager. The Amp Manager function allows for precise reductions in the maximum allowable
eld percentage, making it possible to reduce alternator horsepower load on belts, or to provide gover-
nance to protect the alternator from abnormally large battery or system electrical loads. When activated,
the display will indicate OFF, meaning that no eld reduction is occurring. To adjust, remove the magnet
until the AP code is indicated. Re-activate and hold the magnet to the RED dot. The display will scroll
downward until the desired value is indicated
Field Threshold - Float To Absorption . Controls the criteria used to determine the eld current
threshold required to cycle between absorption and oat charging modes. Factory set at 65%. Raising
“f” increases calculated oat charge time. Adjusted in 1% increments. Span of adjustment is 16% to
96%. To reverse direction of scroll, release “f” code. Reactivate switch with magnet and release when
desired value is indicated.
Field Threshold - Bulk To Absorption . Controls the criteria used to determine eld output re-
quired to maintain calculated bulk charging mode. Factory set at 65% eld output. Raising “fba” shortens
calculated bulk charge time. Lowering “fba” increases calculated bulk charge time. Span of adjustment
is 16% to 96%. To reverse direction of scroll, release magnet and wait for LED to display “fba” code. Re-
activate switch and release when desired value is indicated.
Equalization Duration. Controls the length of time the batteries will be held at equalization voltage.
Maximum time adjustment is three hours. If manufacturer guidelines require longer equalization times,
allow for maximum time, and reset for additional periods as required.
Equalization Voltage. Sets the target voltage applied to the batteries during the equalization pe-
riod. Contact your battery manufacturer for voltage guidelines.

BATTERY EQUALIZATION FUNCTION - (Use Extreme Caution While Equalizing!)
Depending on battery technology and battery manufacturer recommendations, it may be necessary to periodically apply
equalization/conditioning voltage to your batteries to reduce sulfation and equalize the specic gravity of the electrolyte
solution. While it is FAR preferable to equalize your batteries with your shorepower charger at the safety of your slip, the
MC-624 does provide the ability to equalize with the alternator and regulator. NOTE: Equalization voltage and dura-
tion should be in accordance with battery manufacturer guidelines. Equalization programming must be done
with the engine running, as the equalization mode will occur as soon as the program adjustments are made.
