CHARGER CONTROLS AND FEATURES
IMPORTANT! If charging is attempted when the FUNCTION
SELECTOR is in the START position, the automatic circuitry will
be bypassed, causing all settings to be manual.
BATTERY TYPE SELECTOR must be set for the type of battery
being charged. Set to the left DEEP-CYCLE positionfor charging
deep-cycle batteries or any other battery with a built-inhydrometer
"eye", such as the Delco Freedom battery. Set all other battery
types to the right ALL OTHER position.
CAUTION - SET SWITCH CORRECTLY!
Charging a standard battery on the DEEP-CYCLE setting may
result in excessive gassing and possible overcharging.
Charging a deep-cycle battery on the ALL OTHERS setting will
result in an undercharged battery.
Charging a battery (such as a Delco Freedom) with a built-in
hydrometer "eye" on the ALL OTHERS setting will result in a fully
charged battery, but the "eye" may fail to change to indicate a
satisfactory charge level.
AUTOMATIC CHARGING CIRCUIT controls the two 12 volt
settings. It monitors the battery's state of charge and
automatically reduces the current to the battery as it nears full
charge. In some cases, it will taper to such a low rate that the
ammeter wilt appear to be on or near zero for some time. When
full charge is reached, the output to the battery is completely shut
off and the green CHARGE COMPLETE indicatorcomes on. At
this point, the charger continues to monitor the battery's state of
charge. If the battery discharges for any reason, the charger will
turn the output back on until the battery reaches full charge once
again.
NOTE: The 2 amp setting should be selected to charge only
SMALL 12 volt batteries. If used to charge larger automotive or
deep-cycle batteries, full charge may never be fully reached.
The automatic charging circuit is temperature compensating.
will assure that a full charge is reached regardless of the
temperature at which it is being used.
This
REVERSE HOOK-UP PROTECTION CIRCUIT will not allow the
charger to begin charging and will light the red REVERSE
HOOK-UP indicator if the charger is connected to the battery in
reverse.
