ARE Series Chargers

* Equalize charge is required only if cells have experienced a discharge.
** Additional equalize charging is not recommended after initial equalization.
Consult battery manufacturer for particular recommendations.
2.2 FLOAT VOLTAGE ADJUSTMENT
Caution: Do not attempt to set either float or equalize voltage until the unit is out of the current-limit
mode.
The setting of the float potentiometer “FL” on the instrument panel, determines the float voltage level, provided
the rocker switch, also on the instrument panel, is in the “Float” position.
Turning the potentiometer clockwise increases the float voltage. Turning it counterclockwise decreases the
voltage.
In order to correctly adjust, the float voltage, the battery should be in a fully charged condition with some load
connected. Adjust the float potentiometer only while the equipment is operating.
2.3
EQUALIZE VOLTAGE ADJUSTMENT
Caution: Do not attempt to set either float or equalize voltage until the unit is out of the current limit
mode.
The potentiometer for this adjustment is also on the instrument panel and is labeled “EQ”.
Move the rocker switch to the “Equalize” position. Then with the equipment in operation, as it was during float
voltage adjustment, make the equalize voltage adjustment.
The equalize voltage potentiometer works exactly as the float voltage potentiometer – a clockwise turn increases
voltage; a counter clockwise turn decreases voltage.
The equalize voltage setting will depend upon the type of battery used (refer to chart) and the maximum limiting
voltage of the connected load equipment.
NOTE: If used with lead-calcium alloy grid batteries, (not requiring regular equalizing), the equalize
pot should be adjusted to zero (full CCW) to minimize the possibility of over voltage on the load.
2.4 CURRENT LIMIT ADJUSTMENT
Caution: Operating the equipment at greater than 110% of rating is not recommended for periods
greater than 3-4 hours. The current limit setting should be left at 110% for normal operation.
The current limit is factory set at 110% of the rated output current of the power supply. If a lower current limit
setting is desired, it may be set within the range of 50% and 110% of rated DC current. The setting of the current
limit potentiometer, labeled “CL ADJ” and located on the bottom edge of the control board on the inside of the
door, determines the current limit setting.
Turning the “CL ADJ” clockwise increases the current limit setting, turning it counter clockwise decreases the
setting. To adjust, follow on of the procedures outlined below:
A. If dummy load is available:
1. Increase load until 110% of charger rating is reached.
2. Turn “CL ADJ” slowly counter clockwise until the desired setting is reached. For
example, if 90% setting is desired and the equipment rating is 30 amps, stop when 27
amps is reached.
