3 — PROGRAMMABLE PARAMETERS:
BDI
BDI% will automatically reset to 100%. The reset voltage value can be set from
the programmed Full Volts value up to 3.00 VPC, in 0.01 VPC increments.
BATTERY ADJUST
The battery adjustment parameter is used to adjust the BDI algorithm to
compensate for battery capacity. Higher capacity batteries can spend more time
below the Full Volts setting before beginning to lose charge. The battery
adjustment parameter sets the number of seconds of droop required before the
battery state of charge is decremented by 1%. It is adjustable from 0.1 to 20.0
seconds.
BDI DISABLE
The BDI disable parameter, when programmed On, limits the vehicle’s maxi-
mum speed to the BDI Limit Speed when the battery state-of-charge is 0%.
BDI LIMIT SPEED
The BDI limit speed parameter sets the vehicle’s maximum allowed speed when
the BDI disable parameter is programmed On and the battery state of charge is
0%. The BDI limit speed is adjustable from 0 to 100% of drive output.
If the BDI disable parameter is programmed Off, the BDI limit speed will
not be in effect.
