assumes that all other components of the guidance system have checked good. 1. Park the lift truck directly over the guide wire.
Speed Feedback Encoder Test This test should be run when the guidance system is not functioning correctly. 1. Verify the speed feedback encoder is mounted securely to the traction motor. 2. Jack and block the lift truck. 3. Enter Maintenance Mode and travel slowly. See “Maintenance Mode” on page 6-5. The rate of horn chirps should increase as travel increases. Test the encoder in both travel directions.
2. Turn the key switch OFF. NOTE: To test each sensor, you must enter a horn code—one for the load sensor, one for the tractor sensor. When you enter the code, you can test coils individually in each sensor. 3. Enter the horn code to test the tractor or load sensors. To switch between tests, turn the key switch OFF before entering the other code. .
a. If the chirp rate does not change as travel speed changes, or if there are no horn chirps, go to step 4.
Test
Horn Code
Load Sensor
2,1
b. If the chirp rate changes with the travel speed, the speed feedback encoder is good.
Tractor Sensor
2,2
4. Troubleshoot following “Code 2,5” on page 6-50.
a. Hold down the horn button and turn the key switch ON. Do not release the horn yet.
Steer Feedback Encoder Test
b. Wait for the steer LEDs to stop flashing, and release the horn button.
This test should be run when the steering system is not functioning correctly. 1. Verify the steer feedback encoder is mounted securely to the steer motor.
c. Press and release the horn button the number of times as the first digit of the horn code. Each time you press the button, an additional Battery Indicator LED lights.
2. Enter Maintenance Mode. See “Maintenance Mode” on page 6-5.
d. Wait for the Battery Indicator LEDs to turn OFF.
3. Step on the deadman pedal and rotate the steering wheel at different rates of speed. 4. The rate of the horn chirps should increase as you turn the steering wheel faster. a. If the chirp rate does not change, or the horn does not chirp, see “Code 3,6” on page 6-60.
e. Press and release the horn button the number of times in the second digit of the horn code. f. Wait for the Battery Indicator LEDs to turn OFF.
b. If the chirp rate does change with the steering rate, the encoder is good.
Wire Guidance Sensor Test This test should be run when the guidance system is not functioning correctly. This test
