and fire.
Charging the Lithium battery requires the user to set the charger termination current. The charging
process will terminate when the charging current drops to the set termination current.
For using Program mode for charging batteries:
WARNING: FIRE HAZARD! When using the Program mode to set the battery charging
parameters, please consult the battery manufacturer on all voltage and current settings. Using a
wrong setting to charge the battery may overcharge and damage the battery, resulting in battery
explosion and fire.
The following parameters can be programmed in the Program mode:
• Bulk/Absorption Voltage (13.8 – 14.8V)
• Float Voltage (13.0 – 13.8V)
• Mode 2 or Mode 3
Note: When program mode is used, the Battery Temperature Functions are disabled.
Understanding the Digital Display and the Function Keys during Normal Operation:
During normal operation, the display shows the related channel's battery voltage, charging current,
and charging stage ('bUL' – Bulk stage, 'AbS' – Absorption stage, 'FUL' – Float stage) alternately.
When all channels reach float stage, the display starts showing 'FUL' indicating that all the batteries
connected are fully charged.
During the equalization operation on a flooded battery, the numerical section on the display shows a
flashing 'Eq' indicating the equalization process is in progress and does not show the battery voltage
or the charging current.
Understanding the Digital Display Function with no AC Input:
With the unit already turned off (by disconnecting its AC-Input power) and the display completely in
blank, press and hold the 'INFO' key for at least 3 seconds until you see something on the display. The
display will show the voltage on each battery bank (channel) alternately (one at a time), as well as the
charger software revisions (e.g. "u1.5" or higher). If you read "0.6V" or "0.7V" it would mean that there
is not any battery connected to that battery bank terminal.
This feature is useful to know what battery banks (channels) are actually connected to the unit.
Understanding the Function Key 'INFO', 'NEXT' and 'SET' during Charger Setting:
'INFO': Press and hold the key for longer than 3 seconds to enter the charger
setting mode and show function setting. Once the new setting is done, press
'INFO' again to exit the charger setting mode.
'NEXT': Press the key once to keep or save the chosen setting and change the
display to show the next menu to continue other settings.
Note: The selected setting will quickly flash 3 times to acknowledge the setting.
'SET': Press the key to view other available settings or Press and hold the key for
3 seconds to activate or deactivate 'Silent Mode' – 'Auto' icon to show on display
(see more details on Page 5).
Please note: on later editions of the remote display, 'SET' is replaced by 'ESC'.
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 lower constant float voltage to fully top up and maintain
the battery in a fully charged stage.
