be placed in series for a nominal voltage of 12.8 V. This comes close to the nominal voltage of six-cell lead-
acid batteries. This makes the LiFePO
automotive and solar. Like a gel cell, the LiFePO
they are assembled, and an internal protection system is implemented, preventing too deep a discharge.
START/STOP BUTTON
Use this button to start or stop the charging process, after the battery is properly connected and battery voltage
and type have been selected. The display will briefly show "ON" when the START/STOP button is pressed.
After charging has started, pressing the START/STOP button will cause the display to briefly show "OFF".
CHARGING LED INDICATORS
Charging (yellow/orange) lit – The charger is charging the battery.
Charged/Maintaining (green) lit – The battery is fully charged and the charger is in maintain mode.
Reversed Clamps (red) flashing – The connections are reversed.
NOTE: See Operating Instructions for a complete description of the charger modes.

12. OPERATING INSTRUCTIONS

OVERVIEW
Connect AC power and set the front panel ON/OFF switch to the ON position. The switch will illuminate.
Then select an unused charging outlet from the four available. Connect the battery, following the
precautions listed under sections 6 and 7. Select the appropriate Battery Voltage and Battery Type and
press START to begin charging. As charging begins, the Battery Voltage, Type and Display settings are
saved. Then, whenever the unit has been off and AC power is reapplied for 30 seconds and no buttons are
pressed, charging of the battery will resume with the saved settings from the last charging cycle.
DISPLAY
Connecting the station cable clamps to a battery will show the battery voltage, even if voltage was not
previously selected. Change the display setting by pressing the Display Mode Button (see Display Mode
Button, in Section 11).
CHARGING
When charging begins, the yellow/orange Charging LED will be lit.
COMPLETION OF CHARGING
Charge completion is indicated by the green Charged/Maintaining LED. When lit, the charger has stopped
charging and has switched to Maintain Mode of operation.
ABORTED CHARGE
If charging cannot be completed normally, charging will abort. When charging is aborted, the charger's output
is shut off.The display will show "BAD BAT" and an error code. See section 15, Troubleshooting and Error
Codes. To reset after an aborted charge, press the START/STOP button to turn the charger off.
RECOVERY MODE (Non-lithium ion batteries only)
If a battery is left discharged for an extended period of time, it could become sulfated and not accept a
normal charge. The charger will detect this and automatically enter Recovery mode. When this mode is
activated, the display will read "BAD BATT REC". The display will revert to normal operation when normal
charging begins after the battery is recovered. Recovery Mode could take up to 10 hours. If it fails, charging
will abort and the display will read "BAD BAT F02". For more information, see section 16, Troubleshooting
and Error Codes.
MAINTAIN MODE
When the green Charged/Maintaining LED is lit, the charger has started Maintain Mode. This mode of operation
is known as Float Mode Monitoring. In this mode, the charger keeps the battery fully charged by delivering a
small current, when necessary. The voltage is maintained at a level determined by the battery type selected.
GENERAL CHARGING NOTES
• The board-mounted fans run as needed, based on the corresponding board temperature.
• If the charge mode is changed after charging has started (by pressing the Battery Voltage or Battery Type
button), the charging process stops and begins again automatically at the new selection.
• The voltage displayed during charging is the charging voltage and usually will be higher than the
battery's resting voltage.
