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.

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
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
(#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.

Charger will not proceed without user interaction.
LED #2 REVERSE POLARITY:
Lights when the battery connections are incorrect.
The charger is electronically protected so no damage will result, and the output will
remain disabled until the connections are corrected.
VOLTAGE SAFETY CHECK:
12.8V (#1a) and 16V LEDs (#1b) alternate and green test LED (#6)
lights.
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:
for batteries with a battery management system (BMS) that protects
against deep discharge.
IMPORTANT! Before proceeding, confirm the nominal
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.
