Curtis 1230 Manual,
Rev. C
The Battery Discharge Indicator constantly calculates the battery state-of-charge
when KSI is on. When KSI is turned off, the battery state-of-charge at turn-off
is stored in nonvolatile memory. BDI information is viewable via the Spyglass
display and via the Monitor Menu of the 13XX programmer.
Note: BDI values are in units of volts per cell. The standard values for
flooded lead acid and sealed maintenance-free 24V batteries are as follows:
BATTERY TYPE
FLOODED
SEALED
Full volts
2.04 VPC [= 24.5 V]
2.04 VPC [= 24.5 V]
Empty volts
1.73 VPC [= 20.8 V]
1.90 VPC [= 22.8 V]
Reset volts
2.09 VPC [= 25.1 V]
2.09 VPC [= 25.1 V]
Custom values can be entered based on specific batteries in consultation with
a Curtis applications engineer.

DESCRIPTION
Full Battery Voltage
EBV
–
RBV
Sets the voltage at or above which 100% charge is indicated on the BDI
[FBV]
display. The allowable range is from the programmed Empty Battery Voltage
up to the BDI Reset Battery Voltage, in VPC (volts per cell) units.
Empty Battery Voltage
0.90 VPC –
FBV
Sets the voltage at or below which 0% charge is indicated on the BDI
[EBV]
display. The allowable range is from 0.90 VPC up to the programmed Full
Battery Voltage.
BDI Reset Battery Voltage
FBV
– 3.00 VPC
Sets the no-load voltage at which the controller’s battery-state-of-charge
[RBV]
calculator will reset to 100%. When this voltage is present for 6 seconds
(except during regen braking) the BDI is reset to 100%. The allowable
range is from the programmed Full Battery Voltage up to 3.00 VPC.
Battery Recharge Level
20–50 %
Sets the low battery threshold; when the BDI is below the programmed
value, the Battery LED will flash. This will alert the operator that the battery
will need to be recharged soon.
Low Voltage Level
1.33–1.67 VPC
Sets the voltage considered to be a fully depleted battery (16–20 V). When
the battery remains under this voltage consistently, the controller will limit
motor speed to 20%.
