Tuning the Throttle Max
2-c. Apply full throttle and observe the Throttle value. This value
should be 100%. If it is less than 100%, the Throttle Max value should be
decreased to get 100% throttle. After entering a smaller Throttle Max value
(Program » Throttle » Throttle Max), return to the Monitor menu and repeat
this step until the Throttle % value is 100% at maximum throttle position.
2-d. Now that the full throttle position results in a 100% value for
Throttle, slowly reduce throttle until the Throttle value drops below 100%
and note the throttle position. This represents the extra range of motion
allowed by the throttle mechanism. If this range is large, you may wish to
decrease it by increasing Throttle Max. Entering a larger Throttle Max value
(Program » Throttle » Throttle Max) will provide a larger active throttle range
and more vehicle control. Return to the Monitor menu and repeat this step
until an appropriate amount of extra range is attained.
2-e. If a wigwag or unipolar throttle is being used, repeat the procedure
for the reverse direction. Throttle Max should be set such that the throttle
operates correctly in both forward and reverse.
Confirming proper throttle operation
Select a direction and operate the throttle. The motor should begin to
turn in the selected direction. If it does not, verify the wiring to the throttle
and motor. The motor should run proportionally faster with increasing throttle.
If not, refer to Section 7.
3 Basic vehicle checkout
Using the Monitor menu, observe the status of each of the switches included
in your application: mode, reverse, push, speed inhibit. Cycle each input in
turn, observing the programmer. The programmer should display the correct
status for each input.
Similarly, check the throttle and speed limit pot inputs. The correct value
for each input should be displayed.
Verify that all options, such as HPD, are as desired.
To verify the status of the charger inhibit input, plug in the charger and
apply the throttle; the motor should not run.
If everything checks out, lower the vehicle drive wheels onto the ground.
4 Setting system resistance
It is very important that the System Resistance parameter be set accurately.
This procedure must be conducted quickly and with the motor cold. If the
procedure needs to be repeated, ample time must be allowed for the motor to
cool completely. Conducting the procedure with a warm motor will lead to
erroneous settings.
The correct System Resistance value is determined as follows.
4-a. Position the vehicle up against a wall, high curb, or some other
immovable object.
