-c. 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 » Throt-
tle » 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.
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.
The polarity of the motor’s
M1
and
M2
connections will affect the operation of
the emergency reverse feature. The forward and reverse switches and the
M1
and
M2
connections must be configured so that the vehicle drives away from the
operator when the emergency reverse button (the belly button switch) is pressed.

Basic vehicle checkout
Using the Monitor menu, observe the status of each of the switches included
in your application: mode, forward, reverse, interlock, emergency reverse, lift
lockout, EM brake. Cycle each input in turn, observing the programmer. The
programmer should display the correct status for each input.
Similarly, check the throttle input. The correct value should be displayed.
Verify that all options, such as HPD, are as desired. Verify the operation
of the horn and the emergency stop switch.
To verify the status of the charge 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.

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.
