PARAMETER
ALLOWABLE RANGE
DESCRIPTION
Full Voltage
20.0–28.0 V
Voltage when the battery is fully charged.
Note: Allowable range is restricted by the Empty Voltage, Start Charge Voltage,
and Reset Voltage settings.
Empty Voltage
16.0–24.0 V
Voltage when the battery is fully discharged.
Note: Allowable range is restricted by the Full Voltage setting.
Full Charge Voltage
24.0–32.0 V
Voltage, when a charger is connected, above which the battery is considered
finished charging.
Note: Allowable range is restricted by the Start Charge setting.
Start Charge Voltage
21.0–29.0 V
Voltage above which the battery is considered to start charging.
Note: Allowable range is restricted by the Full Voltage and Full Charge Voltage
settings.
Reset Voltage
20.0–28.0 V
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.
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.
Low BDI Level
0–100 %
Sets the battery charge level at which maximum vehicle speed will be limited
in order to protect the battery from deep discharge.
Setting Low BDI Level to zero disables this function and allows the battery to
discharge completely.
Low BDI Max Speed
10–100 %
Sets the maximum allowed vehicle speed when the battery charge falls below
the programmed Low BDI Level.
External Lift Lockout
On/Off
Available only with 1212P.
When programmed On, the lift lockout input (pin 9) activates the lift lockout
feature.
When programmed Off, the lift lockout feature is activated by the controller’s
internal BDI.
Lift Lockout Enable
On/Off
Available only with 1212P.
When programmed On, the lift lockout output is enabled and the horn
output is disabled. The output can be used to drive a relay to control a pump
contactor.
When programmed Off, the lift lockout feature is disabled and the horn output
is enabled.
Lift Lockout Threshold
0–50 %
Available only with 1212P.
Sets the lift lockout BDI threshold when External Lift Lockout = Off. The lift
lockout output will be active when the BDI falls below the programmed
threshold.
Lift Lockout Output Type
0–1
Available only with 1212P.
When set to 0, the output will be pulled low when active. When set to 1, the
output will be open circuit when active.
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.
