EDDY CURRENT BRAKE INSTALLATION

This section will walk you through removing the eddy current brake from the crate,
installing the eddy current brake on model 224 automotive dynos, installing the Theta
Controller, and routing cables.
You will need to provide equipment capable of lifting the eddy current brake off the
crate and into position in your dyno room. You will also need a pair of straps. Dynojet
recommends using single loop style straps.

To prevent possible injury, turn off the dyno electronics and unplug the dyno.

OOLING

Placing the eddy current brake on the left or right side of the dyno will determine the
direction that it turns.
For optimal eddy current brake cooling, the brake should turn in the direction of the
arrows on the rotors.
When running mostly rear wheel drive cars, orient the dyno and brake so the brake is
turning in the direction of the arrows when a rear wheel drive car is on the dyno (as
shown in Figure 1-2).

Note: The dyno will function correctly for front wheel drive cars, but cooling of
the rotors will not be optimal.

The rear wheel drive example below shows the brake turning in the direction of the
arrows on the rotors. In this example, the load cell is in compression.
