Speed Control
• To maximize your vehicle’s driving range only use the speed you need if using the OTF.
• Use the speed knob to control your maximum cruising speed, turn the speed down to the
minimum practical speed necessary for the application. The controller signicantly increases
the operating efciency of the motor as the maximum speed adjustment is reduced.
• Minimize acceleration - hard acceleration demands high in-rush currents from the battery
pack. This increases wear and tear on both the motor and the mechanical systems.
Hill Descent
• Use regenerative braking for hill descent - it puts energy back into the battery and it
increases the life of your brakes. Regenerative Braking can be applied gradually and can
reduce the likelihood of losing traction when going down a hill.
Low Battery Warning
• When the battery discharged warning (1-5 ash) is given by the OTF (if present), the
controller will reduce the amount of power it supplies to the motor to protect the motor.
• Cycling the key will reset full controller power for 1 minute but doing so repeatedly will
adversely affect the life of your motor. Recharge the batteries as soon as possible.
Heavy Duty Usage
• If you notice that your cables or motor are becoming too hot to touch, then your application
is probably too demanding and we recommend that you upgrade the motor to a speed/torque
system, and upgrade the cables to at least 4 AWG.
Warnings
• Always monitor the motor & battery wiring temperatures after changing the programmer
settings (if OTF is present) – particularly when going to higher speeds
• If your battery pack is full, the amount of regenerative braking may be reduced since the
controller has nowhere to put the excess energy.
