Once fully charged the BBU drops the charge voltage to 13.65 / 27.3V (“float” voltage). “Battery Low” LED (yellow): On when battery voltage is <11 / 22Vdc. “Bat Status” relay is de-energized. If the battery voltage drops below 9.3 / 18.3V the load is switched off. “Charging” LED (yellow): On when BBU is charging the batteries. Off when the “Full Charge” LED is on. “Fault” LED (red): On when AC fails. On when external power supply voltage is <11 / 22V. 22V On when batteries not connected. On when battery voltage is <9.3 / 18.3V Fault relay de-energizes for the above conditions. “Battery Reverse” LED (red): Batteries connected in reverse. Fault relay de-energizes and fault LED turns on. Internal fuse opens to prevent damage to BBU or batteries. “Battery Open” LED (red): No batteries connected - takes approx. 60 seconds to detect after turning on BBU. “Fault” LED is on and Fault relay is de-energized. “Drain” input A temporary short between the “Drain” and “COM” terminals switches the load to the batteries until the battery voltage reaches 11 / 22V. At this point the AC power is returned to the power supply and the BBU starts recharging the batteries. “Drain Reset” A temporary short between the “Drain Reset” and “COM” terminals disables the Drain cycle to the batteries. “Enable” input A connection between the “Enable” and “COM” terminals enables the BBU. If terminals are open circuit (Disabled) the BBU functions as a battery charger only. In the event of AC failure the batteries are not connected to the load via the BBU. The BBU is factory preset as Enabled.
