CHARGE PROGRAM
If voltage selection in STEP 1 matches the expected battery voltage and there are no connection errors as described in
STEP 2, then fully automatic operation starts from STEP 3.

TEST
LED #1a / 1b:
Confirms AC power supply to the charger and selected battery
voltage.
Changing voltage selection: Disconnect charger from battery. Place and hold finger on
6
Select-TOUCH sensor. The selected voltage LED brightens to confirm touch. (i.e. if '12.8V'

was on, then '12.8V' will brighten).
After 3 seconds the voltage selection changes, then SAVE (#3), CHARGE (#4) and TEST
TEST
(#6, 7, 8) LEDs flash twice to confirm selection is in memory.
LED #1a => 12.8V
LED #1b => 16V

NOTE: Selection remains even if AC power is lost.

12.8V is selected and a battery with voltage exceeding 14.8V is connected.
Connected battery may be 16V.

Action: Disconnect battery, select 16V.
16V (#1b) and 12.8V (#1a) alternate and red test LED (#8) lights.

16V (#1b) selected and a battery with voltage below 14.8V is connected:
The connected battery may be 12.8V or it may be a deep discharged 16V battery.
Action: Physically check battery. If nominal voltage is 12.8V, disconnect battery and select
12.8V.
If nominal voltage is 16V, hold finger on Select-TOUCH. After 5 seconds program will
proceed to STEP 3.
BMS RESET:

battery voltage matches the selected charge voltage.
Disconnect the charger from mains supply. Wait for LED #1a/1b to go out. Reconnect to
mains supply. A special BMS reset pulse is delivered for up to 5 seconds. The program
should continue to STEP 4.
TEST LEDs #6/7/8 indicate the battery condition prior to charging. Consult the table on
page 2 to match TEST LED indication to an estimated state of charge percentage (SOC%).
During the test:
OPTIMIZE minimum charge time is set according to the test result, varying between 10
minutes for a battery with 80% or higher state of charge to 120 minutes
for a battery with 40% or less state of charge.
Ambient temperature is measured to determine charge voltage parameters.
Charging commences after 10 seconds.
