2.2.2 BBS2000 Operating Modes
Purpose: Describes the Operating modes.
TIP: The LCD automatically displays the following modes when they change.
LCD Shows Explanation
STANDBY
This mode is displayed when the unit is first turned on. The inverter remains off
and the BBS2000 does not provide output power to the loads. If Input line power
is qualified, it automatically switches to Line mode. To provide battery power to
the loads, use the Manual On function (see Section 2.2.11)
ON LINE
The normal operating mode. Input Line power is provided to the loads, the
batteries are charging and the BBS2000 is ready to provide backup power.
BOOST*
The unit automatically transfers to BOOST mode to raise the low Input line
voltage when output drops below the user programmable preset limit.
ON BATT
The unit automatically transfers to Battery when Input line power is unqualified.
The batteries provide power to the loads.
BUCK*
The unit automatically transfers to BUCK mode to reduce the high Input line
voltage when output rises above the user programmable preset limit.
SELF TEST
When “Self Test” mode is active, the unit will enter “Battery Mode” automatically to
test or check if output voltage and waveform are correct, then the unit returns to
“Line Mode” in 1 minute. Users may use “Maintenance Mode” to configure longer
time for the self-test. Default time for the self-test is 1 minute.
LOW BATT
The battery begins to discharge on “Battery mode.” If the battery voltage falls
below the user programmed value (40% default setting), “Low Bat” warning
appears.
* When enabled.
The following mode may be programmed by the User (see Section 2.2.12)
