G8000 Series Installation and Operation Manual
14.8 Changing to Float Charge from Protection Charge (If applicable)
The manual procedure to change from protection charge to oat charge is shown in Step 1-3.This
operation applies to batteries after they have experienced over temperature condition.
See the Note below for an explanation of oat charge and protection charge.
STEP 1
Make sure that the EQUAL CHARGE LED
is “ON”.
STEP 2
Make sure that the “BATT FAULT1” warning
goes away.
STEP 3
Press “FLOAT/EQUAL” button for at least
0.5 seconds.
Procedure completed.
NOTE
The battery is normally being charged at oat
charge mode. To prevent thermal runaway
of the battery, this mode will automatically
be changed to protection charge when a
“BATT FAULT1” (Battery over temperature)
warning occurs.
In protection charge mode, the battery is
automatically charged at a voltage about 5%
lower than oat charge.
If the “BATT FAULT1” warning message goes
away and a programmed duration is elapsed
(about 24 hours), this mode will automatically
be changed back to oat charge. Thus, it is
not usually required to change the recharge
mode manually back to the oat charge.
