Curtis Model 3401T – August 2022
BDI MENU
The source of the BDI percentage can be either the 3401T’s internal BDI calculations or RPDO1. The
parameters on the BDI menu are used for the internal calculations.

DESCRIPTION
Nominal Voltage
0x6400:00
Enumerated
0–2
32-bit
Field Intermediate
0
Specifies the battery’s nominal voltage:
0 = 12/48/80V
1 = 24/60/96V
2 = 36/72V
The BDI algorithm requires that the nominal voltage
is correctly specified.
Charge Full
0x6420:00
1.500–2.500V
1500–2500
32-bit
Field Intermediate
2.350V
Specifies the battery cell voltage above which the
battery is considered charged.
Charge Full must be at least 0.200V above
Charge Empty.
Charge Empty
0x6421:00
1.500–2.500V
1500–2500
32-bit
Field Intermediate
2.100V
Specifies the battery cell voltage above which the
battery is considered as starting to charge.
Charge Empty must be at least 0.200V below Charge
Full and at least 0.010V above Discharge Full.
Discharge Full
0x641E:00
1.500–2.500V
1500–2500
32-bit
Field Intermediate
2.040V
Specifies the battery cell voltage at which the state
of charge is considered 100%.
Discharge Full must be at least 0.120V more
than Discharge Empty and must be between the
following values:
• Charge Empty − 0.010V
• OCR Reset − 0.030V
Discharge Empty
0x641F:00
1.500–2.500V
1500–2500
32-bit
Field Intermediate
1.730V
Specifies the battery cell voltage at which the state
of charge is considered 0%.
Discharge Empty must be at least 0.120V less than
Discharge Full.
OCR Reset
0x6422:00
1.500–2.500V
1500–2500
32-bit
Field Intermediate
2.090V
Specifies the battery cell voltage above which the
BDI percentage is reset to 100%. OCR Reset is
checked only once; the check occurs when the
3401T is powered up.
OCR Reset must be at least 0.030V above Discharge
Full and at least 0.010V less than Charge Empty.
Integration Rate
0x6423:00
2–600 minutes
2–600
32-bit
Field Intermediate
30 minutes
Specifies the minimum time for the BDI algorithm to
decrease the BDI percentage from 100% to 0% or
increase the percentage from 0% to 100%.
Lift Lockout
0x6424:00
0.0–20.0%
0–200
32-bit
Field Intermediate
10.0%
Specifies the BDI percentage below which lift lockout
is activated.
