Note

The battery is normally being charged in 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.

BYPASS INPUT

BYPASS

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 pre-programmed duration has elapsed (about 24 hours), this mode will automatically be changed back to float charge. Thus it is not usually required to manually change the recharge mode back to the float charge.
