Boom Speed to Control Effort Scale

The boom speed to control effort scale value correlates the required PWM duty cycle to the hydraulic valve to create the desired boom speed. To determine the boom speed to control effort scale:

1. Select the Diagnostics icon.

2. Select the Tests tab.

3. Select Target Velocity Test.

   

4. Select Begin.

   

5. Set the Target Velocity to 2° per second.

6. Raise the center rack with one boom lowered near the ground (but at least 24” above the ground).

7. Select Start Test. The boom should raise. When the test is complete, the average velocity will display.

8. Select the Settings (small gear) on the tab.

9. If the boom moved faster than the desired 2° per second, decrease the Boom Speed to control effort value. If the boom moved slower than the desired 2° per second, increase the Boom Speed to control effort value.

   

   

10. Repeat the test for both booms until the speed matches the target velocity (+/- 20%).

    Note:  Test results are affected by solenoid coil temperature. Perform the tests three or more times in rapid succession for best results.
