Before operating the vehicle, carefully complete the following initial setup
procedures. If you find a problem during the checkout, refer to the diagnostics
and troubleshooting section (Section 7) for further information.
Before starting the setup procedures, jack the vehicle drive wheels up
off the ground so that they spin freely. Doublecheck all wiring to ensure
that it is consistent with the wiring guidelines presented in Section 2. Make
sure all connections are tight.
Begin the setup procedures

1-a. Put the throttle in neutral, and make sure the forward/reverse
switches are open.
1-b. Turn on the controller and plug in a programming device. The
programmer should power up with an initial display, and the status LED should
light steadily. If neither happens, check for continuity in the keyswitch circuit
and controller ground.

In the programmer's Parameters Menu, set the Throttle Type parameter to
match the throttle you are using (Type 0–5); see page 22.
It is important to ensure that the controller output is operating over its
full range. The following tuning procedures will establish the throttle deadband
and throttle gain parameter values that correspond to the absolute full range
of your particular throttle mechanism.* It is advisable to include some buffer
around the absolute full range of the throttle mechanism to allow for throttle
resistance variations over time and temperature as well as variations in the toler-
ance of potentiometer values between individual throttle mechanisms.
Tuning the Throttle Deadband
2-a. Select the Monitor Menu. The Throttle % field should be visible
in the display. You will need to reference the value displayed here..
2-b. Slowly apply the throttle until you hear the electromagnetic brake
disengage. Use care with this step as it is important to identify the threshold
throttle position at which the brake is disengaged.
2-c. Without moving the throttle, read the value shown in the Throttle
% field. This value should be zero. If the Throttle % value is zero, proceed to
Step 2-d. If it is greater than zero, the throttle deadband parameter must be
increased. Select the Parameters Menu, scroll down to display the
field, and enter a larger

If you are using a wigwag throttle, you should center it before proceeding with
the throttle tuning procedures. Instructions for wigwag throttle centering (using
the Throttle Autocalibration parameter) are presented on page 23.
