5. UNIT OPERATION
Understanding the Charger
The charger is a three bank battery charger that is capable of charging three battery banks
individually. The three battery banks must be the same battery type.
For the charging mechanism, if more than one bank is connected to the charger, the charger will
charge each individual bank continuously for 15 minutes and then switch to the different bank(s)
and cycle until all battery banks reach float mode. Once all battery banks reach float mode, all
the banks are connected in parallel through a separation diode and will be charged together.
The maximum current the charger can provide during the float mode is about ½ the maximum
current rating of the charger.
For charging GEL, AGM and Flooded batteries:
• The charger can be set to 2 stage (Bulk and Absorption mode) or 3 stage (Bulk, Absorption
and Float mode) charging.
• Each battery bank can have its own maximum charging current and absorption to float
mode current settings.
For charging Lithium batteries:
Each battery bank can have its own maximum charging current and termination current setting.
The charger process will terminate when the charging current drops to the set termination
current.
For using charger as Power Supply (Program setting):
The charger can be used as a constant voltage power supply that will deliver the preset output
voltage (13.3, 13.5, 13.7 V) with the maximum current setting. With this setting, only Bank 1
can be used and the other banks are disabled.
Understanding the Display during Operation:
During normal operation that include normal charging, priority charging and silent charging, the
numerical section on the display show battery voltage (e.g. 12.5V), charging current (e.g. 60A)
and charging stage (e.g. ‘bul’ – Bulk stage, ‘abs’ – Absorption stage , ‘flo’ – Float stage)
alternatively.
During equalization operation on flooded battery, the numerical section on the display show a
flashing ‘eq’ indicate the equalization process is in progress and it will not show the battery
voltage or the charging current.
Understanding the Unit ‘INFO’, ‘NEXT’ and ‘SET’ Button Functions:
To change charger setting,
• Press and hold ‘INFO’ key for longer than 3 seconds to enter charger
setting mode and shows function setting.
• Press ‘NEXT’ key once to save the setting and change the display to
display different setting.
• Press ‘SET’ key to select the displayed function.
• Once new setting is done, press ‘INFO’ again for longer than 3 seconds
to exit the charger setting mode.
Understanding the Three-Stage (Mode 3) Charging:
The Three-Stage Charging (Mode 3) has a Bulk, then Absorption and then Float sequence.
During the Bulk stage, the battery accepts the maximum constant current from the charger. In
the Absorption stage, the battery voltage is held to constant voltage and the charging current will
slowly reduce. In Float stage, the charger continuously produces voltage at a lower level to fully
top up and maintain the battery in a fully charged stage.
The charger will automatically restart the charging cycle in Bulk stage if the battery is discharged
to 12.5V. Also, after seven days, the charger will automatically restart the recharging cycle to
refresh the battery.
Understanding the Two-Stage (Mode 2) Charging:
The Two-Stage charging is similar to the Three-Stage charging except there is no float stage
after the absorption stage. The charger will terminate the battery charging after Absorption. After
seven days, the charger will automatically restart the charging cycle to refresh the battery.
