-B Tuning the Throttle Max
STEP 1. Jack the vehicle wheels up off the ground so that they spin freely.
STEP 2. Plug the 13XX programmer into the controller and turn on the
keyswitch. If your application has an interlock switch, close it.
STEP 3. When the programmer instructs you to select a menu, select the
Test Menu. The Throttle % parameter should be visible in the
initial display. You will need to reference the value displayed here.
STEP 4. Rotate the throttle forward to its maximum speed position and
observe the Throttle % value. This value should be 100%. If it
is less than 100%, the Throttle Max value must be decreased to
attain full controller output at the maximum throttle position.
Select the Program Menu, and decrease the Throttle Max setting.
Repeat this step until the Throttle % value is 100%.
STEP 5. 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 the
Throttle Max value. This will provide a larger active throttle
range and more vehicle control. Using the programmer, increase
Throttle Max and repeat the test until an appropriate amount of
extra range is attained.
STEP 6. If a wigwag throttle is being used, repeat the procedure for the
reverse direction. The Throttle Max value should be selected such
that the throttle operates correctly in both forward and reverse.
