Digital Display Port:
The Digital Display Port has dual functions. It can be used for optional external display or for PC
interface.
Use for external display
The interface port is used for connecting an optional external display. The external display
(sold separately) has identical functions to the built-in unit display.
Use for PC interface
• A KISAE Abso Charger PC Interface Kit (sold separately) is available and is used to
connect between the port and the PC. This can be used to monitor and made changes to
the settings.
• Full details of the KISAE Abso Charger PC Interface Kit, it can be found on the KISAE
website www.kisaetechnology.com
and you can also consult your dealer for more details.
Battery Temperature Sensor Port:
CAUTION
: RISK OF BATTERY DAMAGE. If temperature sensor is not being used, never set
the battery temperature lower than the actual temperature. This may overcharge and
damage the battery.
KISAE Abso Charger Temperature Sensor (sold separately) is available and is used to connect
to one of the negative terminals of the battery. It measures the battery temperature and will
make small adjustments to the battery charging voltage for better battery charging performance.
As Battery Bank 1 is designed for charging the main battery bank on the system, it is highly
recommended to have the battery temperature sensor connected to Battery Bank 1’s battery.
If the temperature sensor is not used, you can also manually set the temperature to Low – ‘Lo’,
Normal – ‘nor’, or High – ‘hi’ to reflect the environmental temperature for better charging effect.
Manufacturing default setting is set to ‘Normal’ temperature. See more details on
Understanding the Battery Temperature Function in Section 5.
Digital Display:
• ‘CH1’, ‘CH2’ and ‘CH3’ represent Battery Bank 1, 2 and 3
respectively. With ‘CH1’ turned on, the numerical value on
the display shows individual battery information like
battery voltage in ‘V’ or charging current in ‘A’. ‘CH 2’ and
‘CH 3’ will always turn on together, the numerical value
on the display shows the total charging current in ‘A’
• ‘GEL’, ‘AGM’, ‘Flooded’, ‘Lithium’ and ‘Program’
represent different battery types setting.
• ‘Auto’ indicates Silent Mode is activated.
• ‘Mode’ only turns on during the setting of charging stage
(Mode 2 - (2 stages): Bulk and Absorption stage only, or
Mode 3 - (3-stages): Bulk, Absorption and Float stage).
• ‘Temp’ only turns on during the setting of battery temperature.

Note 1: Equalization setting can only be used on flooded battery type selection only. See more details on
Procedure to Equalize the Flooded Battery.
Note 2: Charger will terminate charging when charging current drop to below the set charger termination value.
Note 3: Charger act as a power supply with selected constant output voltage and preset maximum output
currents.
