5 — INITIAL SETUP
To congure the 1226 controller so that it is compatible with your vehicle’s characteristics and
requirements, perform the following procedures:
Step 1. Prepare the Vehicle.
Step 2. Congure the rottle. (page 62)
Step 3. Verify the Vehicle’s Conguration. (page 64)
Step 4. Set the System Resistance. (page 64)
Step 1: Prepare the Vehicle
Perform the following steps before programming the controller.
It is critical that you perform these steps.
1. Jack the vehicle drive wheels up o the ground so that they spin freely.
2. Make sure the vehicle is stable.
3. Doublecheck all wiring to ensure that it is consistent with the wiring guidelines. See Installation
and Wiring on page 4.
4. Make sure all connections are tight.
5. Put the throttle in neutral.
6. Turn o the forward/reverse switches.
7. Turn on the controller.
8. Plug the programming device into the controller. e 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.
Step 2: Configure the Throttle
It is important to congure the throttle so that it operates over the throttle’s full range. To do so, you
specify the throttle type, then tune the deadband and the wiper voltage until the throttle performs
satisfactorily.
Note: When you tune the throttle, include a buer around the absolute full range of the throttle
mechanism. is will allow for throttle resistance variations over time and temperature and for
variations in the tolerance of potentiometer values between individual throttle mechanisms.
To congure the throttle, perform the following steps.
1. Select Program » Application Setup » rottle to access the throttle-related parameters. See
rottle Menu on pages 33-34.
2. Set the Direction Source parameter to match the vehicle’s throttle type.
3. Tune the deadband by performing the steps in Congure the Deadband on page 63.
4. Congure the wiper voltage required to produce 100% controller output by performing the steps
in Congure the Wiper Voltage on page 63.
5. Verify that the throttle is correctly congured. See Conrm rottle Operation on page 64.
