The Breakout board jumper settings are preset, however, verify jumpers are set
appropriately as shown in Figure 3-8, Figure 3-10, or Figure 3-13.
Note: The Breakout board is located on the stationary dyno.
2 Verify the hydraulic motor is filled with hydraulic fluid. Refer to “Filling the
Hydraulic Motor with Hydraulic Fluid” on page 3-31 for more information.
3 Turn the dyno electronics on.
4 Verify the dyno has 100-140 psi of compressed air.
5 Press the red button on the dyno pendant. The button should light up indicating
