PARAMETER RANGE DESCRIPTION
Full Voltage model specic Voltage when the battery is fully charged.
Note: Allowable range is restricted by the Empty Voltage,
Start Charge Voltage, and Reset Voltage settings.
Allowable Full Voltage range:
1212S-2xxx: 20.0 – 28.0 V
1212S-3xxx: 30.0 – 42.0 V.
Empty Voltage model specic Voltage when the battery is fully discharged.
Note: Allowable range is restricted by the Full Voltage setting.
Allowable Empty Voltage range:
1212S-2xxx: 16.0 – 24.0 V
1212S-3xxx: 24.0 – 36.0 V.
Full Charge Voltage model specic Voltage, when a charger is connected, above which the battery
isconsiderednishedcharging.
Note: Allowable range is restricted by the Start Charge setting.
Allowable Full Charge Voltage range:
1212S-2xxx: 20.0 –32.0 V
1212S-3xxx: 36.0 – 48.0 V.
Start Charge Voltage model specic Voltage above which the battery is considered to start charging.
Note: Allowable range is restricted by the Full Voltage and
Full Charge Voltage settings.
Allowable Start Charge Voltage range:
1212S-2xxx: 21.0 – 29.0 V
1212S-3xxx: 31.5 – 43.5 V.
Reset Voltage model specic Voltage at which the BDI calculator will be reset to 100%, after
the charger is disconnected and the controller is powered up.
Note: Allowable range is restricted by the Full Voltage setting..
Allowable Reset Voltage range:
1212S-2xxx: 20.0 – 28.0 V
1212S-3xxx: 30.0 – 42.0 V.
Discharge Factor 0.1–10.0 Discharge rate of the battery. Larger values are for larger batteries,
which discharge more slowly.
Charge Factor 0.1–10.0 Charge rate of the battery. Larger values are for larger batteries,
which charge more slowly.
The Battery menu allows any lead acid battery to be installed and the BDI
algorithm tailored to match it. Actual usage duty cycle greatly affects the settings
and the overall accuracy of the BDI algorithm. The power level and type of
battery charger used also affect the BDI algorithm, and therefore testing must
be done to match the charger as well.
See Appendix C for guidelines on setting up these BDI parameters.
