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 float 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 float 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 float
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 float 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 float charge. Thus, it is not
usually required to change the recharge mode
manually back to the float charge.
