Understanding the Priority Bank Charging Function
The charger comes with a unique ‘Priority’ bank charging function that allows the user to force
the charger to fully charge one of the three banks to float mode before it switches to other banks.
This function will only work for GEL, AGM, Flooded, and Lithium battery type setting only.
To set this function, see Appendix A in details.
Once the chosen bank is charged to float stage, this function will turn off automatically and it will
switch to charge the other 2 banks to float stage. Once all 3 banks reach float stage, the charger
will start the float charging process together.
Tips: Only use this mode if you want to fully charge a specific bank as soon as possible.
Understanding the Auto Mode Function
The charger also comes with another unique ‘Auto’ mode function that reduced the fan speed
and charger current automatically for a silent operation.
Tips: Use this function during night time or when a quiet environment is needed. Please also
note that the charging time will increase in this mode because the charger is not running
at maximum power.
This function can switch to ON or OFF at any time during the charging period.
To set this function, press and hold ‘SET’ button for 3 seconds to execute the ‘Auto’ mode. The
‘Auto’ icon will show on the display.
To turn this function off, press and hold the ‘SET’ function for 3 seconds to exit the ‘Auto’ mode.
The ‘Auto’ icon on the display will turn off and the charger current and the fan speed will return
to normal.
Understanding the Protection Features
De-rating Charging Current:
When the charger senses the environmental temperature is above 50°C, the maximum
charger current will de-rate to 1/2 of the value. It will recover automatically back to maximum
charging current when the environmental temperature drops to below 45°C. A02 warning code
will display.
Over Temperature Shutdown:
When the charger senses the environmental temperature is above 60°C, the charger will
shutdown. It will recover automatically when the environmental temperature drops to below
45°C.
Battery Reverse Polarity:
When a reverse polarity is connected to the battery bank, Fault Code E03 on display will
appear. In some case, the user replaceable DC fuse located near the DC Output terminals
may blow and Error code E08 will display.
AC Input Voltage Protection:
The charger will shutdown when it senses the AC input voltage is outside of the operating
range. A fault code will display. The charger will recover automatically when it senses the AC
input voltage has returned back to the normal operation range.
Charging Dead Battery
The charger is designed to charge batteries with terminal voltage greater than 2.5Vdc.
Understanding the Error Codes
Error codes will show on the display when either an internal fault such as high internal
temperature or external fault like AC input voltage out of range is detected. The unit will
shutdown.
Code Condition Corrective Action
A01 Temperature Sensor (BTS) is
defective. Check and or replace the sensor.
A02 with
black
lighting
flashing
Inlet temperature is high >50°C
(122°F) or ventilation of the unit is
blocked charger will shutdown
shortly. Cool down the unit by reducing the
charging current or improve the
ventilation near the unit.
