Automatic Override Functions:
When positive power is applied to the “Ignition” terminal (do not connect to ground), it
will force the charger to connect to CH3 as long as CH3 is in within the ‘Override operating
range’ in the specication.
Programming Your Charger
Press and hold the key for longer than 3 seconds to enter charger setting mode and
show function setting. Once new setting is done, press ‘MENU’ again for longer than 3
seconds to exit the charger setting mode.
Press the key once to keep / save the chosen setting and change the display to show the
next menu to continue other settings.
Note: The selected setting will quickly ash 3 times to acknowledge the setting.
Press the key to view other available settings.
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
oat voltage to fully top up and maintain the battery in a fully charged stage.
The charger will automatically restart the full charging cycle if it senses the battery bank is
discharged to lower than 12.5V for lead acid batteries and 13.3V for lithium batteries.
Understanding The Battery Temperature Functions
The Battery Temperature Sensor is included with the charger to protect your battery and
provide better charging voltage accuracy.
When the battery temperature sensor is used, it is highly recommended to be installed on
the main battery bank at the negative terminal. The sensor senses the battery temperature
and overrides the manual temperature settings and makes small adjustments to the charging
voltage. If using lithium batteries, leave temp setting “NOR” (Normal) and leave temp sensor
disconnected.
