Tuning the Throttle Max
c. Apply full throttle and observe the rottle value. is value should be 100%. If it is less than
100%, the rottle Max value should be decreased to get 100% throttle. Aer entering a smaller
rottle Max value (Program » rottle » rottle Max), return to the Monitor menu and repeat
this step until the rottle % value is 100% at maximum throttle position.
d. Now that the full throttle position results in a 100% value for rottle, slowly reduce throttle until
the rottle value drops below 100% and note the throttle position. is represents the extra range
of motion allowed by the throttle mechanism. If this range is large, you may wish to decrease it
by increasing rottle Max. Entering a larger rottle Max value (Program » rottle » rottle
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.
e. If a wigwag or unipolar throttle is being used, repeat the procedure for the reverse direction.
rottle 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. e motor should begin to turn in the selected direction.
If it does not, verify the wiring to the throttle and motor. e motor should run proportionally faster
with increasing throttle. If not, refer to Section 7.
1212P models: e polarity of the motor’s M1 and M2 connections will aect the operation of the
emergency reverse feature. e forward and reverse switches and the M1 and M2 connections must
be congured so that the vehicle drives away from the operator when the emergency reverse button
(the belly button switch) is pressed.
Step 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, emergency reverse. Cycle each input in turn, observing the
programmer. e programmer should display the correct status for each input.
Similarly, check the throttle and speed limit pot inputs. e 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.
