
MODE-1 is annunciated for 4-seconds after A.C. Power applied, where the Right
Most LED flashes. Refer to the
LED CHARGE MODE INDICATOR TABLE’ and
CHARGE MODE SETTING TABLE .
o
‘Power On’ LED and Detection LED will illuminate to indicate that AC power
is applied AND battery is in the process of being detected.
o
If the Red ‘Power On’ LED Flashes, it is indicating that the pending Charge
Cycle will apply a special charge called ‘Equalization Charge’. Refer to
Equalization Charge Cycle section for description of stage.

STAGE ONE – PRE-QUALIFICATION TEST
o
Yellow (Charging) LED flashes slowly (once per second) to test battery.
Charging stops if faults such as connection of 24v charger to a 36V battery
pack or safety timers timed out, etc. Refer to ‘Troubleshooting Guide’ if an
Error Code was displayed.
o
Duration of this stage is dependent on condition of battery – approximately
10 seconds under average circumstances, but if your battery pack was
allowed to severely discharge to less than 1.75Vdc per cell (example – 21v
for a 24v battery), then the charger may take several hours of slow charging
to try to slowly bring the battery up to above 1.75Vdc per cell.

STAGE TWO – BULK CHARGE (Constant Current)
o
Yellow (Charging) LED illuminates continuously indicating charging at full
rated output. While charging, voltage is monitored for the occurrence of the
next charging stage.

STAGE THREE – ABSORPTION CHARGE (Constant Voltage)
o
Yellow (Charging) LED illuminated continuously. The charger now regulates
at Absorption Voltage Level while monitoring charge current.
o
Once Charge Current has decreased to a sufficiently low level, this stage
exits to the next stage.
o
The Battery Pack has achieved approximately 95% State of Charge.

STAGE FOUR – TOP OFF CHARGE STAGE
o
Both Green (Charged) and Yellow (Charging) LEDs illuminate.
o
Replenishing last 5-10% of battery capacity. Charging at a low Constant
Current rate, this stage monitors for time and dv/dt to terminate.
o
The Battery Pack has achieved approximately 95% State of Charge.
o
NOTE: If using a Charger MODE set to charge a Flooded USBattery only,
this stage may take up to 4 hours to complete.
 STAGE FIVE – EQUALIZATION CHARGE CYCLE
o
This is a special charge condition that is selectively applied and is not
typically applied to every battery, nor with every charge cycle. If it is applied,
the next stage becomes Stage Six. If not applied, then the next stage
becomes Stage Five.
o
The Red ‘Power-On’ LED will flash during the entire cycle in which
Equalization Charge Stage has been invoked, and the flashing will cease
when charge has completed.
