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
1-a. Put the throttle in neutral, and open the forward/reverse switches.
1-b. Turn on the controller and plug in the 1311 programmer. 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.
Throttle
2
Set the Throttle Type parameter (Program »Throttle »Type)to match the throttle
you are using; see page 15.
It is important to ensure that the controller output is operating over its
full range. The following tuning procedures will establish the Neutral Deadband
and Throttle Max 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 Neutral Deadband
Starting with the Neutral Deadband set to its default value, adjust this parameter
if necessary to provide a good balance. The deadband should be wide enough for
the throttle to reliably return to neutral when released, yet without an excessive
amount of travel in the "dead" zone before power is applied.
2-a. If the throttle travels too far when starting out of neutral before the
brake disengages, decrease the Neutral Deadband value. If the brake sometimes
doesn't engage when the throttle is returned to neutral, increase the Neutral
Deadband value. The default setting of 10% should work for most applica-
tions.
2-b. If a wigwag or unipolar throttle assembly is being used, the procedure
should be repeated for the reverse direction. The Neutral Deadband value should
be set such that the throttle operates correctly in both forward and reverse.
*
If you are using a wigwag or unipolar throttle, you should center it before
proceeding with the throttle tuning procedures. Instructions for centering,
using the Throttle Calibration parameter, are presented on page 17.
