ADVANCED BREAKOUT BOARD
The Advanced Breakout Board (ABOB) can be used to control braking for four-wheel
drive dynos. When two dyno drums are equipped with braking, it is important for
braking to be the same for each dyno drum when slowing a vehicle.
Slowing one set of wheels (front or rear) more rapidly than the other set may
cause serious damage to the vehicle.
The ABOB allows each dyno drum to be slowed as necessary so that the dyno drums
remain synchronized. When the red brake button on the pendant is pressed, the
ABOB uses information from each dyno drum to determine its speed and apply more
braking to the faster drum so that the two drums slow at similar speeds.
The ABOB can also be used to control the braking load applied to the dyno drum
during load control testing to provide advanced load control capabilities.
Note: If your dyno is equipped with an eddy current brake on each drum, use an
Advanced Breakout Board to control the braking.
